Prof Bo Gunnar Liedberg	The research interests of Prof. Bo Liedberg can be divided into three main areas Surface Chemistry and Self Assembled Monolayers This part of the research concerns fundamental studies of adsorbates and ultrathin molecular architectures, like Self-Assembled Monolayers (SAMs), on solid supports. The group was very early in studying self-assembly of substituted alkylthiols on gold substrates. A key activity has been to study temperature driven phenomena occurring in such assemblies as well as in adsorbed layers on top such SAMs. Oligo(ethylene glycol) and oligosaccharide SAMs have attracted considerable attention, both experimentally and theoretically, because of their structural characteristics and advantageous properties in contact with biofluids. Another area concerns interfacial water and ice. Temperature programmed studies have been undertaken to improve the understanding of the nucleation and microscopic wetting behavior of water/ice. The complexity of the SAMs has increased over the years and we are today focusing on architectures based on SAMs bearing multivalent chelator heads, helix-loop-helix polypeptides and receptor functions. Bioinspired and Biomimetic Nanoscience This research concerns the development of nanoscale architectures fabricated using either top-down or bottom-up protocols (or a combination of both). We are, for example, developing plasmonic arrays based on 100 nm gold nano dots on silicon and glass surface for amplification of optical fluorescence signals, so-called metal enhanced fluorescence (MEF). We are also developing composite materials based on a combination of de novo designed peptide scaffolds, planar surfaces and nanoparticles of controlled size and shape. A novel concept based on peptide folding has been used for controlled assembly of gold nanoparticles. The group is also involved in the development of Dip Pen Nanolithography (DPN) for patterning of surfaces on the 30-100 nm length scale. This work is performed jointly with a previous student of the group who nowadays is setting up a nanolaboratory at the Institute of Physics, Vilnius. We are also involved in several EC projects where different types of micro- and nanoscale patterning tools are employed for production of coatings for biofouling, sensing and biomedical applications. Optical Biosensors, micro- and nanoarrays The group has a long experience in developing optical transducers for biosensing application. We were the first to demonstrate the use of surface plasmon resonance for studies of bioaffinity interactions at surfaces, a technology that today form the backbone in SPR/Biacore instruments developed for biospecific interaction analysis (BIA). We are today using it in combination with ellipsometric interrogation and imaging optics for microarraying, and in combination with nanoparticle for studies optical enhancement phenomena. This includes, for example, microarray chips for protein multiplexing. The group is also working on the development of generic biochips for studies of ligand-receptor binding. Besides working on microarray fabrication for protein detection and analysis we are also developing biochips for the safety and security area. Selected publications 1.

Asst Prof Chen Gang	The overall goal of my research group is to employ cutting-edge biophysical techniques to better understand the structures and the physical-chemical properties of RNAs and RNA-ligand complexes to provide deeper insight into and to facilitate precise control of the diverse biological functions involving RNA. We aim to use the fundamental knowledge to fight neurodegenerative diseases, cancers, bacterial and viral infections by designing and discovering novel therapeutic ligands targeting RNA. To approach the challenging goals, we have assembled a multidisciplinary team with expertise ranging from molecular biophysics, structure biology, computation, chemical synthesis, cell biology, to medical healthcare. The research projects of current interests are: (1) characterizing the molecular recognition interactions (e.g., hydrogen bonding and aromatic base stacking) accounting for structure, stability, and dynamics of RNA structural building blocks such as internal loops, hairpins, triplexes, and pseudoknots, (2) probing the complex energy landscapes of RNA folding and assembly with protein, (3) designing and discovering therapeutic ligands (small molecules, oligonucleotides, peptides, peptide nucleic acid, etc.) targeting RNA, (4) developing nucleic acid based biosensors to rapidly detect toxic/pathogenic agents in food products and human body, and (5) discovering and characterizing novel nucleic acid based catalysts for important organic and inorganic reactions at mild conditions. We employ various conventional and cutting-edge biophysical and biochemical techniques including laser optical tweezers, NMR, UV-Vis, fluorescence, SPR, gel electrophoresis, PCR, chemical synthesis of modified oligonucleotides and peptides, in vitro transcription, protein expression, and cell culture assay.

Asst Prof (Adj) Chiam Sing Yang	My application directed interest is directed at energy related research. I am especially interested to study the origin of open circuit voltages in different type of solar cells where charge separation differs. I am also interested in exploring new materials or the use of nanostructures. This can be used for either photovoltaic applications or even photocatalysis. I am also looking at ways to improve transparent conductor. Currently, this is directed at flexible substrates for printed applications. In another aspect of my interest, I’ll like to understand the interface energy separation between different materials. For example, for oxide-semiconductor, it is subtle but important to consider aspect of extra-atomic relaxation, differential charging and various chemical reactions at the interface before directly utilizing measurements from photoelectron spectroscopy to determine the interface energy alignments. In doing so, we can then critically examine different models in alignment, including charge neutrality model and the interface induced gap states model. I hope to extend the technique to overcome issues of ionization cross section from organic materials to give better accuracy in their HOMO/LUMO alignment.

Assoc Prof Cho Nam-Joon	Our research is focused on engineering approaches to solve challenging medical problems with strong emphasis on: 1) biosensing, 2) hydrogel tissue engineering, 3) biopharmaceuticals, and 4) drug delivery. To support these translational projects, we have several ongoing academic and industrial collaborations including those with Harvard University, Stanford University, and Roche Ltd. Despite advances in therapeutic drugs and tools, much work remains towards the early identification and eradication of infectious diseases. We are developing model membrane sensing platforms to interrogate the mechanisms of virus life cycles, especially that of the Hepatitis C virus (HCV). We are also leveraging these engineering strategies to combat a wide range of viruses including dengue and influenza. In a related project, we are characterizing the molecular interactions of phospholipases involved in inflammatory response and the pathogeneses of many cancers. To more effectively translate new medicines into clinical therapies, we also have an active regenerative medicine team focused on liver tissue engineering. The liver is an important organ that is the site of HCV infection. Moreover, liver toxicity is a major challenge which accounts for the costly failure of many drugs late in the pipeline. Therefore, our primary aim in this area is to develop an artificial liver tissue platform to study HCV infection and drug toxicity. Taken together, our overall research initiative seeks to engineer artificial membrane and tissue platforms to probe biological systems, and to translate these findings into enhanced therapeutic and drug delivery options that more effectively target infectious diseases, inflammatory disorders, and cancer.

Therefore we have developed a bottom-up strategy going “from molecules to devices” via organic synthesis, supramolecular self-assembly and device fabrication. - Supramolecular self-assemblies @ surfaces The templated self-assembly of individual nano-objects on surfaces provides a versatile route towards the development of functional 2D arrays for energy, catalytic and magnetic applications. Supramolecular nanoporous networks are unique architectures able to trap atoms, molecules or nanocrystals of pre-determined size, shape and properties. The properties of these highly-organized sophisticated materials are explored at the atomic/molecular scale and finally integrated as active materials into various applications. - Organic solar cells The combination of p-type and n-type organic semiconductors allows to design photovoltaic organic solar cells. In order to enhance the photon-to-electron conversion efficiency of these all-organic devices (today > 10%) it is mandatory to introduce interlayers in the sandwich structures. We investigate novel interlayer materials which could facilitate hole collection at the anodic interface and one day substitute the ubiquitous PEDOT:PSS. - Hybrid organic-inorganic magnetic heterojunctions We investigate the possibility to use organic ultra-thin film semiconductors as tunnel barriers in magnetic heterojunctions such as {Fe3O4/Organic/Co}. Controlling the nanoscale morphology of these organic thin films is essential (AFM, CS-AFM). Magnetic measurements are performed to investigate the decoupling between the two ferromagnetic electrodes via the organic layer.

This allows for a simple approach in the design of copolymer for self-assembly and to understand the conditions for self-assembly.

Assoc Prof Lim Teik Thye	Prof Lim's scope of research projects encompasses both practical application of environmental technologies for pollution control and investigation of the process fundamentals. His core areas of research interest focus on application of advanced oxidation processes for water and wastewater treatment, developing novel functional materials for water purification, and developing innovative subsurface remediation technologies. He has over the years developed a range of nanomaterials for treating organic and inorganic micropollutants in surface waters, industrial wastewaters, and groundwater. He has also worked on projects exploring innovative use of industrial wastes for various applications, such as construction, earthwork, and environmental preservation. His current research projects are as follows: Novel photocatalysts This research engineers a novel photocatalyst for enhancing photocatalytic redox processes under solar radiation to remove emerging contaminants in water. It leverages off the complementary strengths among environmental process engineering, materials engineering and advanced materials characterization to develop a new-generation photocatalyst system. The advanced photocatalyst is a composite of nitrogen-doped titania (N-TiO2) supported on the powdered activated carbon (AC), or N-TiO2/AC. The composite have dual functionality, exhibiting high adsorptive properties for a variety of organics and photoactivity under visible light. The synergistic properties of the N-TiO2/AC composite enables its on-site regeneration, producing zero waste stream. Selective nanoporous adsorbents The goal is to develop various functional nano-structured materials such as layered double hydroxides (LDHs), zeolites, calcium aluminosilicates and nanoporous carbons to selectively adsorb trace inorganic contaminants, organic contaminants, and biomolecules that are difficult to be sequestrated using conventional adsorbents. The materials, such as LDHs and zeolites, can also function as catalysts to remove recalcitrant contaminants in water and air. Several types of LDHs have been synthesized in our laboratory. The LDHs have been evaluated for sorption of Cr(VI), As(III), As(V), Se(VI), and other oxyanions found in groundwater, surface waters and industrial wastewaters. Removals of up to 99% of certain oxyanions are possible. Bimetallic zerovalent metal particles The research group has synthesized nano-scale, bimetallic particles such as Ni/Fe and Pd/Fe for catalytic reductive transformation of halogenated alkanes and haloaromatics. The transformation pathways for these contaminants have been established for different types of synthesized bimetallic particles, through kinetic and mechanistic examinations of the experimental findings. The effects of catalyst content and particle ageing on their reactivities are investigated. Aqueous matrix effect on the transformation kinetics has been also examined in order to understand the possible performance of these reactive particles in industrial wastewater and contaminated groundwater.
Asst Prof Ling Xing Yi	The research programs in our laboratory combine chemistry, nanotechnology, and materials science approaches to develop functional nanostructures with novel catalysis, plasmonic and sensing applications. Our research activities involve nanoparticle synthesis, surface chemistry, self-assembly, nanopatterning, nanofabrication, and materials and device characterization. Nanostructures for optimal solar energy conversion The amount of solar energy striking the earth’s surface in one hour is enough to power human activity for one year. Hence, solar energy provides one of the best options to sustain human civilization. An efficient photosystem is able (1) to absorb a large amount of broadband solar energy at full solar spectrum, (2) convert photons into electron-hole pairs efficiently, and (3) perform catalysis reaction to produce fuel at high yield. Currently, most photocatalysts suffer from low reaction efficiency. The main goal in this project is to design nanostructures with artificial photosynthesis properties to achieve high solar fuel conversion. Our strategy is focused on fabricating well-defined nanostructures by combining bottom-up self-assembly and top-down nanofabrication techniques. Important information will be gained to drive the solar-to-fuel photocatalysis towards commercialization and to reduce human’s dependence on non-renewable fossil fuel.

Asst Prof Loh Zhi Heng	The central theme of our experimental research program is the study of coherent electron and nuclear dynamics in molecules and nanomaterials. Coherent electron motion and the ensuing quantum dynamics set forth by either optical excitation or nonresonant strong-field ionization with few-cycle laser pulses will be probed with attosecond to femtosecond time resolution. This proposed work builds upon my previous work, in which coherent electron motion in Kr+ ions that accompanies the formation of a spin-orbit wave packet is observed (Nature, 2010). In the case of molecules and nanomaterials, the typical ~1-eV energy spacing between their valence electronically excited states translates to a periodicity of a few femtoseconds for the coherent electron motion. Charge migration that is mediated by electronic quantum coherences therefore occurs at rates that are at least two orders of magnitude faster than Marcus-type charge transfer. Moreover, the comparable time scales for motion of the electronic and nuclear wave packets presents, in many cases, the possibility of unraveling non-Born-Oppenheimer dynamics. The main experimental techniques that are employed include attosecond time-resolved core-level transient absorption and transient photoelectron spectroscopies, in which soft x-ray pulses produced in a tabletop setup by high-order harmonic generation are used as probe. These soft x-ray studies are complimented with optical pump-probe measurements employing few-cycle (~5 fs) laser pulses. The ultimate goal of our studies is to exploit quantum coherences to enhance the performance of nanoelectronics and artificial light harvesting systems.
Assoc Prof Loo Say Chye Joachim	I. Particulate Systems as Drug Carriers A range of biocompatible materials (i.e. PLGA and hydroxyapatite) are synthesized as microparticles and/or nanoparticles for drug delivery. In this work, we have synthesized multi-layered particles with drug localization at different layers. The aim is to control the release of drugs by altering particle size, layer thickness and other particulate parameters. On the same platform, mesoporous bioglass and hydroxyapatite are also synthesized to release therapeutic proteins. II. Targeted Delivery of Hybrid Particles for Osteomyelitis Osteomyelitis, or bone infection, is currently treated through systemic delivery of antibiotics over a period of time. Our approach is to utilize nanoparticles as drug carriers to delivery antibiotics to infected bone tissues, thereby increasing efficacy and reducing drug dosage. In this work, we have synthesized hybrid particles, with PLGA as core and hydroxyapatite as coating. These particles will be targeted to infected bone sites through the use of a suitable targeting ligand. III. Drug-eluting Balloons (DEB) The aim of Drug-eluting Balloons (DEB) is to deliver drugs on-site during balloon angioplasty.

In vitro cytotoxicity tests are conducted through a range of assays and in vivo tests are conducted on zebrafish models. Toxicity results will be evaluated in reference to various particulate parameters to ascertain the key properties that influence toxicity and biocompatibility.
Asst Prof Loo Sun Sun Leslie	Our group has been interested in studying the role of molecular structure and dynamics upon the properties of polymers and polymer nanocomposites. Organic-inorganic hybrid nanocomposites have shown potential for a wide range of applications due to their enhanced mechanical, thermal and electrical properties. However, while many hybrid systems have been characterized and properties evaluated, much current work is not systematic and addresses only macroscopic issues. There is still little understanding of how to put together an optimal organic-inorganic combination which will achieve a certain enhancement in nanocomposite properties. This is evidenced by the fact that not all nanocomposites demonstrated improvement in properties due to a lack of understanding of the basic interactions at the organic-inorganic interface. To date the nature of this interface is not well-characterized. - We have formulated our research thrusts in two different aspects: one is through the use of spectroscopic techniques and the other is through the fundamental study of molecular interactions at interfaces. In the first area, spectroscopic techniques are important for investigating molecular and surface properties at the nanoscale level. The nanoscale dimensions of the nano-particles require the use of instruments which can probe the nanoscale interactions between the particles and the polymer matrix. Spectroscopic techniques allow the discrimination of inter- and intra- molecular forces that exist between polymer and nanofillers. Furthermore, the strength of such interactions can also be studied. The use of solid state nuclear magnetic resonance (NMR) spectroscopy has allowed us to demonstrate the enhanced mobility of polymer chains during active tensile deformation (Loo et al., Science 2000). We have also employed Fourier transform infrared spectroscopy to elucidate the mechanics of deformation and thermal degradation in polymer nanocomposites (Zhang and Loo, Polymer 2009; Loo and Gleason, Macromolecules 2003). - In the second area, we have formulated model systems in which we can better ascertain the role played by interfaces in affecting the performance of polymer nanocomposites. Recently, we have demonstrated with our model system of the different effectiveness of nano-fillers in enhancing the mechanical properties of fully amorphous versus semi-crystalline polymers (Zhang and Loo, Macromolecules 2009). We have also succeeded in using Langmuir-Blodgett technique to deposit layered silicate onto a polymeric surface and studied its properties (Zhou and Loo, accepted by J. Colloid & Interface Sci. 2009). - From our work, we endeavour to produce organic-inorganic nanocomposites with better properties by intelligent manipulation of the interfacial interactions. This will have a great impact on the design of new materials with novel applications.

Prof Ng Wun Jern	NG WUN JERN's research interests are largely in the area of water and wastewater management. The focus of his efforts has been on investigations into water quality, treatment science, and development of treatment technologies. These investigations span the water quality spectrum - ranging from ultra-pure water to high strength and potentially inhibitory wastewaters. His research output may be found in some 400 publications. These include journal papers, conference presentations, book chapters and monographs, reports, and patents. His latest book publication is titled "Industrial Wastewater Treatment" (Imperial College Press). He is currently working with colleagues on a book on engineered wetlands in tropical applications and one on water reclamation. Current R&D interests revolve around effluent treatment and include dehalogenation under bioreductive conditions. Of particular interest are the chloro-compounds and dehalogenation under acidic conditions with biomass sculptured into granules. The interest in bioreductive (instead of bio-oxidative) processes stems from concern over energy costs and carbon footprints of treatment processes. Anaerobic processes are therefore of interest when used to manage strong wastewaters from industrial and agro-industrial sources. Current R&D interest focuses on thermophilic anaerobic processes and gas productivities and quality. Conceptually there is a shift from viewing the anaerobic process as a wastewater pretreatment device to one which is intended to recover energy from the wastewater. Extending this interest is the work on biosorption where sorption is used to concentrate carbonaceous material from low strength wastewaters prior to anaerobic degradation of the sorbent with gas recovery. This approach deviates from the conventional approach of using anaerobic processes such as the UASB or anaerobic filter to address low strength wastewaters. Laboratory studies typically use the cyclic process configuration although larger scale studies can be with the cyclic or continuous flow configuration. In aerobic treatment, there is interest in the MBR applied with granulated biomass. The interest is on biofouling mitigation using this modified biomass morphology. There is also interest in using the MBR and the concept of "back seeding" to achieve better nutrients removal and degradation of resistant organics (eg textile dyes).

Prof Peter Preiser	My research interests focus on the molecular mechanisms by which the malaria parasite is able to avoid host immunity and adapt to changes in the host cell environment. One of the main problems in developing an efficient malaria vaccine is the ability of the parasite to evade host immune responses. Immune evasion happens both at the level of the infected red blood cell and at the process of invasion, the step at which the parasite infects a new cell. A key focus area of the lab is to understand the mechanisms on how the malaria merozoite recognizes and penetrates the erythrocyte. To address these questions we have particular focused on the role of the Reticulocyte Binding Protein Homologues (RH) family of proteins which is found in all malaria species and has been implicated on playing a role in immune evasion and parasite virulence. Using both the human parasite Plasmodium falciparum as well as the rodent parasite P. yoelii we have been able to address question relating to mechanisms regulating parasite virulence as well as getting a cleared understanding on how these large proteins mediate their function. An interesting upshot of this work is the possibility of using them as part of a malaria vaccine formulation. In addition to merozoite invasion the lab has also spend significant effort in elucidating the biological role of the STEVOR and PIR multigene families identified in P. falciparum and P. vivax respectively. While STEVOR is unique to P. falciparum the PIR multigene family is found not only in P. vivax, but also rodent and simian malaria parasites. My research group has focused on developing a range of reagents that allow us to address what the role of STEVOR is in parasite development. We have recently been able to show that STEVOR is highly expressed in patient isolates and may play an additional role in immune evasion. We are now further characterizing how STEOVR functions. The PIR gene family provides a unique opportunity to study antigenic variation in a rodent model and possibly utilize the information gained in this system to understand how these genes may work in the intractable human parasite P. vivax. Currently, our efforts focus on understanding how the pir genes are transcriptionally regulated. A more recent effort is to gain new insights into how human malaria parasites interact with their host. Until recently most research efforts have focused on using culture adapted parasites but it has become clear that significant information in relation to host parasite interactions are lost in this system. We are therefore interested in using the P. falciparum and P. vivax microarray platform developed here at NTU (in collaboration with Professor Zbynek Bozdech) to investigate differences in the transcriptional profile of parasites obtained directly from patients with different clinical symptoms. This effort has recently given significant new insights into the biology of P. vivax.

Asst Prof (Adj) Quek Su Ying	The focus of my research group is ‘Materials Design for Next Generation Electronics, Spintronics and Thermoelectrics’. With Moore’s law and advances in nanoscale materials synthesis, next generation devices will be one million times smaller than a mosquito. Charge transport at such length scales is fundamentally different from that in present-day macroscopic devices. We use first principles approaches (i.e. approaches with well-defined approximations but no adjustable parameters) to make predictions on the electronic structure and transport properties of different material systems, such as graphene, topological insulators and single-molecule junctions. The uniqueness of our approach is that we can combine many-electron theories with mean-field theories into a practical and predictive tool to predict transport properties in nanoscale systems. We also work closely with experimentalists to understand experimental observations and guide experiments.

Asst Prof Rupshi Mitra	Neurobiology of Resilience Stress targets everyone; but not everybody succumbs to it. Some develop stress-related psychopathology, anxiety, depression, dementia, while others weather it well and even emerge healthier. What makes some individuals resilient and others not? Comprehensive studies on 9/11 survivors and war veterans report that positive emotion helps resilient people re-route physiological resources activated by stress into successful coping strategies. Stress is known to cause brain damage, shrink neurons of hippocampus (memory center of brain) and enhance emotional learning along with neuronal growth in amygdala (emotion center of brain). Our research (@ Resilieo) is geared to find out how we can minimize and prevent brain damage caused by stress. Also, what is different and special in resilient individuals in terms of brain changes during/after stress? With this backdrop, we venture into 4 different lines of investigation. 1. Is there any difference in brains of resilient and vulnerable individuals? Our study on rats exposed to predator stress showed distinctive pattern of neuronal branching within amygdala of resilient individuals. Well-adapted (resilient) animals had more densely packed neuronal branching and maladapted (vulnerable) animals had more spread out neuronal branching of amygdala neurons. Questions we are pursuing now include, what determines individual variation in neuronal branching? And what are the possible factors mediating this? 2. How to rescue or prevent stress-induced damages (enhance resilience)? In addressing this question we employed gene therapy as a technique to deliver genetically altered proteins through viral vectors into specific brain regions. Targeted infusion of therapeutic molecules within amygdala rescued stressed animals from maladaptive anxiety, abnormal stress-response and neuronal over growth (hypertrophy). We continue to identify newer molecules for therapeutic intervention within amygdala and other brain regions. 3. Developing animal model of resilience Enriched environment is known to induce positive behavior and protection against brain damage. We are testing different enrichment paradigms to develop a testable animal model of resilience. Initial results are promising. Short term enrichment rescues maladaptive fear response in stressed animals. 4. Are resilient individuals better adapted? In an interesting new finding we showed that male rats exposed to enriched environment for a short 2 week period were more attractive and preferred as mates by females over non-enriched males. The enriched male rats also had stronger defense response against predator. Thus resilience not only makes individuals cope better with stress, but also has a bigger scope of adaptability in an ever-changing environment. Resilience triggers several physiological pathways that are directly beneficial for basic survival drives, namely, reproduction/mate-choice and protection from danger. We continue to investigate how enrichment drives basic physiology to be more adaptive? What are the pathways and molecular factors triggered by enrichment in this context?

Asst Prof Samir Hemant Mushrif	Continuously depleting petroleum resources, energy shortage due to ever increasing demands, and environmental concerns are driving the research towards finding novel, low cost, functional materials, catalysts and processes, capable of being commercialized for sustainable energy in the future. Hydrogen production and storage, fuel cells, biomass conversion to fuels and chemicals are some of the high potential areas that are currently being explored. Microscopic understanding of the governing physico–chemical interactions in materials and processes is crucial in developing these technologies. Gleaning fundamental insights into the mechanistic details of a process or into aspects that determine how a material is formed and it functions can help optimize the process operating conditions and material properties. The general focus of the research in the group is to characterize (i) the synthesis and behavior of catalytic and energy storage materials, particularly carbon based and active metal doped materials, and (ii) the chemistry of lignocellulosic biomass conversion, in the presence of these materials, using a multiscale modeling and simulation approach. The hierarchical multiscale approach, developed on the foundation of first principles/quantum mechanical laws and in synergy with experimental findings are implemented for materials and process design. Advanced multiscale molecular modeling methods like density functional theory, first–principles molecular dynamics, metadynamics and reactive force–fields are gaining increasing attention from researchers in chemistry, catalysis and materials community for the advancement of knowledge in these fields. Given the important role that chemical engineers play in developing novel materials, catalysts and processes, a paradigm shift in modeling and simulation in chemical engineering is now occurring and a strong workforce skilled in employing these molecular modeling techniques in chemical engineering research needs to be developed. Samir strongly believes that the students and post-docs working in his group will be trained to spearhead this emerging area in chemical engineering. Additionally, they will also gain international exposure through collaborations with experimental and theoretical researchers abroad.

Asst Prof Sum Tze Chien	My research interests are on the development and application of time-resolved and time-integrated optical spectroscopy techniques to study a broad range of emergent nanoscale and light harvesting systems. Specifically, I focus on investigating light matter interactions; energy and charge transfer mechanisms; and probing carrier and quasi-particle dynamics in these systems. Broadly, I can categorize my group’s efforts in three main areas: (a) nanomaterials nanophotonics; (b) mixed dimension heterostructures; and (c) organic photovoltaics (OPV) and plasmonic OPV. 1. Nanomaterials Nanophotonics One of the longest on-going project is on investigating the carrier and quasi-particle dynamics in Semiconducting Nanostructures Nanophotonics. We have worked on a range of systems – ZnO nanowires, CdS nanowires and nanobelts, ZnSe nanowires, ZnTe nanowires and nanobelts etc. New insights were gained in these studies – for example, (1) in one study involving ZnO nanowires, we established that the fast trapping of carriers to the green-emission related centers is through an ultrafast excitonic Auger recombination mechanism; (2) in another project on Cu-doped ZnO, we verified the charge transfer times from the ZnO host to the Cu subsystem occurs within 39 ps to form an “intermediately bound exciton” that is reponsible for the Green Emission in Cu-doped ZnO; (3) A depiction of semiconductor nanowires under lasing action with single photon excitation (SPE) vs two photon excitation (TPE). The commonly accepted paradigm that the higher pump intensities needed for TPE would correspond to higher exciton density threshold (nth) for two-photon pumped lasing is re-examined by Tze-Chien Sum and co-workers using femtosecond time-resolved spectroscopy. Our results show that a much lower nth is needed to achieve lasing in single ZnSe nanowires with TPE compared to SPE. This finding has significant implications for the photo-stability and durability of nanowire lasing. (4) recently, in a project involving CdS nanowires, we developed a new method for tailoring the nanowire lasing modes utilizing the intrinsic self absorption via the Urbach tail states etc. This work is published in Nanoletters. 2. Mixed Dimension Heterostructures In this project, we focus on controlling the light harvesting and light emission properties of novel CdSe dot/CdS nanorod heterostructures (a system of mixed dimensionality). This is achieved through a good understanding the optical properties and charge transfer dynamics in these nanoheterostructures. Utilizing the CdS shell as an antenna for light harvesting and the quantum confinement afforded by the size of the dot, our group has been able to achieve ultralow threshold lasing over a range of emission wavelengths. This ultralow threshold is achieved through the large absorption cross-sections and suppressed Auger recombination rates in these nano-heterostructures. This work is published in ACSNano. 3. Organic Photovoltaics (OPV) and Plasmonic OPV In this work, we seek to understand energy transfer mechanisms in hybrid organic photovoltaic devices, in particular that of the exciton and polaron dynamics resulting from interchain effects under device conditions (field-induced changes in the optical behaviour). Systems include hybrid Au nanowire/P3HT-PCBM photovoltaic devices and fiber-P3HT-PCBM systems. The recombination pathways will be investigated using both time-resolved photoluminescence and transient absorption spectroscopy. The knowledge gained would serve to guide the design of such organic materials inimproving the PCE through chemical and structural modifications. One recent highlight is the acceptance of our paper on investigating the loss mechanisms in Ag nanoparticle blended OPV cells in Nature Communications.

The project focuses on the development of nano-sized achiral and chiral packing materials for Super-critical fluid Chromatography (SFC), Capillary Electrophoresis (CE) and Capillary Electrochromatography (CEC). Judging from the viewpoint of novelty of science, there are to date no known research work published in open literature on the application of chiral-nanomaterials having size ranging < 1.5 ?m for SFC, CE and CEC analyses.

Asst Prof Terry W.J. Steele	Surface Functionalization of Thin Films Surface functionalization of biocompatible materials is an area under tremendous development for medical implants. The medical implant bulk materials often lack the required surface properties needed for blood compatibility (hemocompatibility), tissue adherence, or promotion of host-cell growth. Secondary surface modifications attempt to address these issues with the grafting of known biocompatible polymers. To address the significant need for a highly versatile surface coating, we have designed a surface function methodology that incorporates water based ‘green chemistry’, acrylate-based combinatorial libraries, and living polymerization techniques. This strategy will be applicable to most known materials typically employed for solid medical implants, while providing an unprecedented versatility with a wide choice of functional groups, surface densities, and layer thicknesses. Ocular Delivery Through Periocular, Unidirectional, Biodegradable Discs We propose an innovative practical and proactive strategy to circumvent the practical hurdles in delivering the anti-CMV drug to the retina, in a safe, effective and affordable manner. We propose to develop a unidirectional nano-drug delivery technique that remains periocular (subtenon’s space) but provides drug delivery into the vitreous over a prolonged or intermittent period yet maintain an adequate concentration at the retina. We will design a biodegradable disc with selective permeability on the two surfaces. The surface adjacent to the sclera will be permeable for unidirectional drug delivery into the eye, while the other surface will be non-permeable, thus obviating the risk of diffusion of the drug externally. The aim of the therapy is to suppress viral replication, halt the progression of disease, minimize retinal damage, prevent drug resistance, prevent local complications and preserve visual function. In short term, the proposed biodegradable disc will aim to deliver the optimal concentration of the drug near site of lesion and the concentration of the drug will remain sustained over period of six months thereby preventing the need for repeated intraocular injections and also prohibit the patient to come to clinic for repeated injections. Removable after six months won’t be necessary as well, as the polymer components are designed to slowly dissolve and be metabolized into the tissue. Blood Vessel Joining (Anastomosis) With Adhesive Biodegradable Inserts Anastomosis—the joining of two blood vessels—requires precise placement of sutures through the two blood vessels that need to be healed together. The technique is technically challenging and requires a long learning curve through practice on cadavers, in vivo animal sacrifices, or both. The suturing practice of today has been nearly the same for 100 years. As the surgical theatre continues toward laparoscopic and keyhole surgeries, catheter based methods for surgical anastomosis will be sorely needed. Practical limitations to vascular surgeon’s abilities limit sutures to only the most easily accessed vessels and vessel diameters greater than 1 mm. New methods are needed for impossible to access areas such a cerebral blood vessels (i.e. stroke treatments). Methods to join micro-vasculature—such as arterioles and venules—are needed to advance severed limbs and associated limb or organ transplants. Pipe sleeves in construction and plumbing are commonly used to join gaps, protect pipes from the environment, and repair damaged or leaky plumbing. Similarly, we have designed biodegradable pipe sleaves made from FDA approved implantable polymers. In our design, the polyesters would be cast into thin film cylinders, no longer than 1-2 cm, 0.5-5 mm in diameter, and 100-500 micrometers thin. These cylinders would incorporate pressure sensitive adhesives on their outer surface to seal and join two opposing blood vessels.

Assoc Prof Zhao Yang	Miniaturization of electronic and mechanical devices over the past century has brought immeasurable impact onto human lives. Commercial microelectromechanical systems have reached micron scales, and bona fide molecular apparatuses began to emerge setting the stage for upcoming integrated nanoelectromechanics. Dr. Zhao and coworkers systematically investigate carbon-nanotube-based oscillators, bearings and rotators via molecular dynamics simulation in order to establish their optimal operating conditions and to facilitate function-oriented designs. In addition, particular attention is paid to utilization of nanomachinery devices as nanolabs to study energy exchanges among various degrees of freedom, ergodicity on energy surfaces, and equipartition as systems relax, and to test fundamental hypotheses of thermodynamics and statistical mechanics. The advent of ultrafast femtosecond laser spectroscopy brings about intense research interest in relaxation dynamics of photo-excited states in liquids and solids. Newly-arrived technological capabilities to control femtosecond pulse durations and down-to-one-hertz bandwidth resolutions provide novel probes on vibrational dynamics and excitation relaxation. Dr. Zhao and coworkers formulate time-dependent polaronic wave functions that facilitate microscopic modelling of photo-generated excitation relaxation and realistic computation of various third-order optical response functions, and help to achieve a satisfactory comparison between theory and experiment. Carbon nanotubes are attractive candidates for a variety of applications thanks to their remarkable physical, chemical, and mechanical properties. Optical absorption and fluorescence spectroscopy measurements have become an important tool for structure-based characterization and DNA-assisted manipulation of carbon nanotubes. Dr. Zhao and coworkers establish visual, intuitive connections between optical absorption line shapes and their underlying nanotube structures, which are scrutinized by more sophisticated semi-empirical and DFT calculations.
Asst Prof Zhao Yanli	The research programs in the Zhao group focus on organic and materials chemistry and branch out into the related fields of biological, physical, and medicinal chemistry. We utilize interdisciplinary approaches to investigate the emerging problems at the forefront of chemistry and materials, aiming to address some of the technological needs in today’s society, such as responsive nanomaterials, general approach for controlled drug delivery, and sensing devices for medical diagnostics and gene-chip technologies. The applications in cancer therapy, energy, and sensor technology are keenly investigated at the more advanced stages. Those undergraduate students, graduate students, and postdoctoral scholars who get involved in these programs will gain multi-faceted knowledge in several areas. They will participate in the transformation of simple compounds into more complex ones, and ultimately into advanced materials for real life applications.
