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.

Prof Boey Yin Chiang, FreddyBiodegradable Drug Eluting Stents (15 members): The group, co-led with A/P Subbu Venkatraman, has developed a platform drug eluting stent technology which is applicable for urological, coronary, vascular and cranial therapy. The patent is premised on a multi-layered fully biodegradable stent which can release multi-drugs simultaneously in a controlled release. A start up company, Acacia Biomedical, has been funded to $2m to commercialize the work. Ongoing work seeks to develop nano features on the stent surfaces to promote hemo-compatibility by endothelial cell growth. Electroactive Materials (12 members): The group, co-led with A/P Ma Jan, has developed a PZT blood pump and a frictionless micro-pump using PZT actuators for implanted drug release. The group is presently studying the development of a fully flexible polymer-based impedance pump. The group has formed a start up company to exploit this technology commercially. The group has also initiated computational modeling to seek optimal material designs. Synthesis of Rare Earth Nano-materials (8 members): This project seeks to use a pre-cursor and high energy approach to evolve desired nanosized morphologies for Rare Earth materials, including Yittrium, Cerium, Lanthanum etc. The processes employed include flame hydrolysis, electro-atomization, plasma spraying and atomization etc. Multi-functional bio-imaging probes for targeted cancer therapy (5 members): This project involves the development of biocompatible multi-functional nano-probes, for bio-imaging and targeted cancer therapy. It is a joint-collaboration with the prestigious Mayo Clinic, USA. The group, co-led with A/P Ma Jan and Dr Joachim Loo, has developed the capability of functionalizing these nanoparticles. Results from animal trials have shown these bio-imaging probes to be promising for targeted cancer therapy. The group is currently surface modifying these nano-probes to further increase their tumour-targeting efficiency.
