Assoc Prof Alfred Tok Iing Yoong	1) Carbon-based Field-Effect Transistor Sensors The biosensors market, which is currently at USD 9.9 billion, is expected to reach USD 18.9 billion in 2019 (GIA Report, 2014) propelled by the growing population and health issues. Our group capitalizes on this emergent market and researches on disposable and low-cost sensor suitable for real-time sensing in field conditions. Our group focuses on sensors for biological and gas detection applications. 2) Synthesis of Nanostructured Materials using Atomic Layer Deposition (ALD) Atomic layer deposition (ALD) has evolved to be a unique tool for nanotechnology with atomic level control of the depositions, 3D conformity and homogeneity. Film depositions can be realized for complex non-planar topographies for a wide range of applications such as energy conversion and storage, nanoparticle catalysts, nanostructures for drug delivery, gas separations, sensing, and photonic applications. Our group focuses on ALD materials for solar cell, hydrogen generation and smart window applications. 3) Hard & Tough Materials for Ballistic Protection Application The next generation of military vehicular and soldier system requires light-weight materials with high strength-to-weight ratio. Our research focuses on the synthesis and densification of nanostructured materials & desired composite architecture to significantly raise the ballistic protection capability. The B-C-N-O group of compounds are potential candidates to form novel materials for ballistic protection application as they inherent the unique properties from both boron nitride and boron carbide which are known for their light weight, high hardness, low friction coefficient and high wear resistance. Prof Tok leads a team of collaborators in armour material research ranging from high temperature synthesis of novel superhard materials and consolidation by state-of-the-art Spark Plasma Sintering to advanced characterisation techniques such as depth of penetration test using Two-Stage Light-Gas Gun. 4) Institute for Sports Research Our group is involved in the Institute for Sports Research, working on the damping property of midsoles which is based on carbon nanotube (CNT). CNT’s high aspect ratios (length/diameter) is particularly desirable for mechanical reinforcement, and it is found that the vertical aligned (VA)CNTs perform well in damping, to dissipate the energy absorbed under compression (Figure 7). Our present job is to tune the damping property of VACNT by adjusting the length, diameter and area density etc. parameters and try to reinforce the polymer with VACNT to fabricate midsole material with better cushion property. 5) NRF-CREATE In accordance with the objectives of the Energy Thrust Program of the NRF-CREATE Project, our group is focused on the design and synthesis of highly functional nanomaterials, which enables energy harvesting and conservation. Recently, novel graphene oxide synthesized nanoballs and nanoflowers were synthesized. These exhibit potentials for supercapacitors and energy applications. In general, these activities results in above 50 publications, 17 patent applications and projects discussions with companies regarding commercialization possibilities.

We recently developed series of molecules such as for example dipyrranylidenes and organo-cobalt complexes, that we used to fabricate efficient photovoltaic solar cells. 2. Oxide-based photoelectrochemical systems We aim at converting efficiently sunlight into clean and readily usable fuels such as hydrogen or methane on a large scale. One of the most promising technologies consists in splitting water into hydrogen and oxygen through solar irradiation of semiconductor-based devices. We recently designed various efficient PEC systems based on either WO3, Cu2O, or BiVO4 among others, and used them under sunlight illumination to produce hydrogen. 3. Supramolecular self-assemblies on surfaces The self-assembly of organic molecules on solid surfaces provides a versatile route towards functional 2D arrays in view of energy, catalytic and magnetic applications. Our group develops unique supramolecular architectures by controlling the size and shape of the molecular bricks. We then observe and manipulate the assemblies at the atomic/molecular scale by means of scanning tunneling microscopy (STM).

Nature is able to catalyze all of the aforementioned chemical transformations in a highly efficient manner, and does so under ambient conditions using enzymes containing highly abundant first-row transition metals. Being able to reproduce the general function of these enzymes using small molecules would be highly desirable, and that is what our research aims to achieve.

Assoc 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.

Assoc Prof Massimo Pica Ciamarra	We are interested in understanding the physics of disordered many-particle systems via statistical mechanics tools and numerical simulations, which is arguably one of the most pressing needs in material science.

The main difficulty is the developing of a theoretical framework connecting the macroscopic and the microscopic scales in the presence of disorder. Some topics of specific interest are: 1. glass transition 2. suspensions of soft deformable particles, e.g. microgels 3. liquid with density anomalies 4. rheological properties of disordered particulate systems, with applications to earthquakes 5. pattern formation in driven particulate systems, e.g. segregation 6. transport properties in disordered media

Prof Ng Wun Jern	NG WUN JERN's research interests are largely in the area of water, wastewater, and sludge and agri-wastes management, with recovery of useful materials and energy. The focus of his efforts has been on investigations into water quality, treatment science, and development of treatment technologies and systems. These investigations span the water quality spectrum - ranging from ultra-pure water to high strength and inhibitory wastewaters, and organic sludges to agri-wastes management for recovery of soil fertility and crop yields. 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 publications are titled "Industrial Wastewater Treatment" (Imperial College Press) and "Wetlands for Tropical Applications" (Imperial College Press). 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 and slurries from industrial and agro-industrial sources. R&D interest is on hydrolysis, staged and phased anaerobic processes, process stability and kinetics, gas productivities and quality, and recovery of resources. Conceptually there is a shift from viewing the anaerobic process as a wastewater pretreatment device to one which is intended to recover resources. 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). Aerobic processes are also used to produce enzymes, phytohormones, and beneficial microbial consortia from horti-and agri-wastes. NG now leads his own research group, the Environmental Bio-innovations Group (EBiG), which as its name would suggest has focus on solutions which can be applied on the issues faced in the region. While not limited to bioprocesses, there are more numerous such solutions with intention to achieving more sustainable and circular approaches.

Assoc Prof Oliver Martin Mueller-Cajar	Photosynthetic organisms provide us with food and other materials by using light energy from the sun to capture carbon dioxide from the atmosphere to make usable sugars. Almost all CO2 enters the biosphere via the enzyme ribulose-1,5-bisphosphate carboxylase oxygenase (Rubisco). In spite of the crucial importance of this process Rubisco is non-specific and slow, which has forced nature to hugely overexpress the protein, or to use tricks such as biochemical or biophysical carbon concentrating mechanisms to saturate the enzyme with substrate. Genomic studies have uncovered that Nature possesses a great diversity of Rubiscos and associated protein machinery to perform the task of CO2 capture, much of it poorly characterized. Research in my laboratory aims to mechanistically describe the biochemistry of CO2-fixation related machinery. By increasing our understanding of the sophisticated mechanisms that have evolved in remote branches of the tree of life, we hope to provide knowledge that can later be applied to improving the photosynthetic efficiency of crop species. An emerging interest concerns the use of cyanobacteria as a synthetic biology platform. This involves both the utilization and implementation of heterologous CO2 fixation machinery, as well as the potential to channel the photosynthate towards compounds of scientific and commercial interest.

His contributions in the field so far has been in the terahertz region where he demonstrated classical active and passive analogues of electromagnetically induced transparency through near field coupled metamaterial resonators, sensing with metamaterials, chiral metamaterials, ultra-high quality factor Fano resonances, and ultrafast superconductor metamaterials. Dr. Singh’s recent research focuses on addressing the issue of losses in subwavelength plasmonic metamaterials and investigates new dynamic materials that could be integrated with metamaterial resonators to achieve the active control of the photonic devices with exotic properties.

Prof Sum Tze Chien	My research focuses on investigating light matter interactions; energy and charge transfer mechanisms; and probing carrier and quasi-particle dynamics in a broad range of emergent nanoscale light emitting and light harvesting systems using Femtosecond time-resolved spectroscopy. These can be categorized under two main research themes: (1) light emitters/lasing and (2) photovoltaics. I have also established a 3rd category: (3) Aspirational Areas to explore new ideas and concepts away from my two core research themes. Specifically, I seek to address the following three questions in these systems: (a) Where did the energy go? That is the interplay of carrier/quasi-particle dynamics between the host energy levels, defect energy levels and the dopant energy levels. (b) What are the underlying photo-physics and light-matter interactions that give this system its unique characteristics? That is the various processes such as carrier-carrier scattering, carrier-phonon scattering, radiative recombination and auger recombination etc. (c) How can these properties/technologies be improved for practical applications? That is how the knowledge gained be used for the development of novel optoelectronic devices; nanolasers; and photovoltaic devices. Today, my group tackles a broad spectrum of research problems in emergent materials (such as halide perovskites, 2D materials etc) ranging from novel photophysics, solar cells, LEDs, lasing, spin phenomena, hot-carrier phenomena and nonlinear properties. (1) Light Emitters/Lasing: We seek to understand the interplay of carrier/quasi-particle dynamics between the host energy levels, defect energy levels and the dopant energy levels and the factors affecting amplified spontaneous emission or lasing in these II-VI nanostructures such as ZnO nanowires, CdS nanowires and even the mixed dimension CdSe dot/ CdS nanorod heterostructures and organic-inorganic halide perovskites. (2) Photovoltaics: Ultrafast optical spectroscopy allows us to trace the fate of the carriers and quasi-particles in photovoltaic devices from genesis to the end with timescales spanning over ten orders of magnitude. Correlated with electrical characterization techniques, new insights into the mechanisms of charge generation, transfer, trapping, recombination and transport in novel PV materials can be gained through these studies. (3) Aspirational Areas: Presently, we live in a highly competitive era of rapid technological changes and shortened innovation cycles, where a keen sense and nimbleness to seek out opportunities is key to sustaining economic growth and our quality of life. These aspirational areas on 2-D Materials, novel nonlinear optical properties and spin phenomena allow us to explore new ideas and concepts apart from our core research.

Assoc Prof Tan Soon Keat	Dr Tan's research interests include application of geographical information system (GIS) in water resources, numerical simulation of flow for hydraulics and coastal engineering applications. His current research projects include hydrodynamic consideration of mega underwater structures and application of wetland technologies in the removal of pharmaceutical products from wastewater streams. Dr Tan specilaises in urban water management, rainfall-runoff modeling as well as water quality modeling, flooding, drainage, urban response, climate change and future scenarios analysis. Managing surface water in terms of quantitative distribution, storage and transport, removal of water-borne contaminant, particularly trace quantity of drugs and pharmaceutical products from waste-water streams are challenges in the management of water resources, and in particular, supply of raw water in the face of climate change and rapid urbanisation. A viable and feasible solution is to employ wetland technology as a means to remove contaminants and management of peak runoff. Under the supervision of Dr Tan, a research team is carrying out a series of constructed wetlands experiments with raw water spiked with selected contaminants. The research work has produced meaningful results and highly cited publications since its inception in 2009. Currently Dr Tan is leading research work on strategic development of coastal, urban scape and water resources, in response to climate change as well as developmental scenarios.

Asst Prof Wang Mingfeng	Biological systems are featured by emergent properties in many processes such as energy and chemical transduction, communication, adaptation, self-repair and reproduction. They provide the proof-of-concept for what can physically be achieved with nanotechnology. For example, the ways in which biological systems transform and store energy, as well as their capabilities to perform self-repair and to adapt to external conditions inspire materials scientists and engineers how to manipulate energy, entropy and information in synthetic nano/micro systems. The mission of my research group is to develop novel polymeric and supramolecular materials with bioinspired hierarchical structures and advanced functions, broadly defined, for energy sustainability and human health. We enable this goal through a highly interdisciplinary research program across chemistry, materials science, biology and engineering. Our specific aims include: 1) To develop bioinspired light-harvesting complexes by design, synthesis and assembly of functional molecules, polymers and nanoparticles. 2) To understand interfacial transport of energy, charge and mass in hierarchically assembled structures with integrated functions. 3) To explore new materials and device structures for sustainable energy conversion and storage. 4) To develop multifunctional nanoscale vectors for smart biodiagnostics and nanomedicines.

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.
