Vg Asst Prof Andreas Markus KiebeleMy current research is focused on electrochemical charge storage systems. Specifically we are working on printable, flexible energy storage which include primary and secondary batteries, supercapacitors and hybrid electrochemical capacitors (HEC). Through the use of nano-materials such as carbon nanotubes (CNT), nanowires (made by electro spinning or synthesis) and other nanoparticles we aim to achieve better device characteristics and easier printability. In addition to this, we are also investigating suitable printable electrolyte materials.

Reliability physics and characterization of nanoscale transistors (negative-bias temperature instability, hot-carrier effects, gate oxide breakdown, low frequency/RF noise, metal gate/high-kappa gate stack, non-volatile memories, silicon-on-insulator transistors, nanowire devices etc.) 2. Nano-characterization techniques (conductive atomic force microscopy, high-resolution transmission electron microscopy and associated anaytical techniques for alternative gate dielectrics, nanowire devices etc.) 3. Characterization of novel devices (e.g. tunneling FETs, novel memories etc.)
Asst Prof Arvind RajendranArvind's research interests are in adsorption and chromatography. His focus is on using supercritical fluids as eluents for large scale chromatographic separations, such as the simulated moving bed (SMB) and preparative chromatography, applied to the separation of pharmaceutically active enantiomers. His interests and specializations include adsorption of supercritical fluids, swelling of polymers in supercritical media and gas separation using rapid pressure swing adsorption (PSA) processes.
Assoc Prof Cai WenjianProf Cai's areas of expertise are system modelling, control and optimization, multivariable system identification and control, sensor and instrumentation, mechanical system simulation and design, and intelligent systems. His current research works focus on industry applications in building HVAC processes, renewable energy processes and environmental processes.
Asst Prof Cesare SociWe are interested in the fundamental properties of materials related to small dimensionality and large interface area. Understanding these properties is essential to exploit them in emerging technologies, such as renewable energy sources. In particular we focus on two classes of nanostructured materials, namely organic and inorganic semiconductors, and on their interplay, from basic scientific issues all the way to the device level. Some topics of specific interest are: 1. Nanowire synthesis and devices: semiconductor nanowires are synthesized by different approaches, including top-down and bottom-up methods, and lithographic techniques are used to fabricate nanowire arrays and devices. 2. Organic semiconductors: we study the fundamental properties of organic semiconductors and their use in "plastic electronics." In particular we focus on the interplay between charge carrier photogeneration and exciton recombination, which is a determining factor of the performance of organic solar cells, light-emitting diodes and field-effect transistors. 3. Organic-inorganic hybrid systems: we investigate the optoelectronic properties of hybrid organic-inorganic heterostructures specifically targeted to light sensing and photovoltaic applications, combining microscopy, optical and photocurrent spectroscopy, and nanofabrication technologies.
