A/Prof Tan Swee Ching and his team have successfully developed a high output solid state bioelectrochemical device with a Mechanoresponsive Electrolyte, which exhibited a fivefold photocurrent improvement over the previous record. The photocurrent enhancement is achieved through a ‘satellite-dish effect’ whereby an array of natural light-harvesting complexes absorb light from a wide spectral expanse and concentrate the excitonic energy to a base layer of ‘energy trap’ proteins. This work has been published in Advanced Materials..
In collaboration with a network of German research groups A/Prof. Stefan Adams’ group designed and realized the ceramic Na+ ion conductor with the fastest room temperature ionic conductivity, Na11Sn2PS12, and revealed the mechanism giving rise to its superionic performance utilizing the bond valence site energy method developed in Adams' group. The work has been published in Angewandte Chemie International Edition.
A/Prof. Wang Qing Receives NRF Investigatorship Award The explosive growth of computation unit density and the requirement for high-level integration bring huge demand for power delivery and heat dissipation for micro-processors. With the support of NRF Investigatorship Award, A/Prof. Wang will work on a novel “e-blood” concept — a hierarchical fluid network mimicking the human brains, for concurrent powering and cooling of microchips. Redox targeting concept, pioneered by the PI, is expected to endow the redox system with significantly enhanced energy/power density and thermal/power stability.
A/Prof. Ouyang Jianyong and his team discovered the precursor effect on the crystallization of hybrid organic-inorganic perovskites. The methylammonium iodide was found to affect the supersaturation concentration and interfacial energy of the crystallization process of perovskite single crystals. This work has been published in Angewandte Chemie International Edition (http://onlinelibrary.wiley.com/doi/10.1002/anie.201710234/abstract).
Assist. Prof. Tan Swee Ching and his team have successfully developed a new approach to boost the open circuit voltage of protein-based photovoltaic devices by employing highly oxidising redox electrolytes in conjunction with an n-type silicon anode. The design involves photo-generation of electron-hole pairs in both the protein and the silicon electrode complementing each other. This work has been published in Advanced Functional Materials. (http://onlinelibrary.wiley.com/doi/10.1002/adfm.201703689/full).
Dr Benjamin Tee has been awarded the NRF Fellowship Award. The project aims to create new multi-scale sensor technologies that can enable high performance environment sensing by learning from biology.
Goh Pei Shan, year 4 student from the cohort of AY14/15 went for a self-initiated Student Exchange Programme (SEP) at University of College Dublin (UCD) in year 2017.
Fong Cheng Hung; year 2 from cohort AY16/17 whom department nominated to go for the Japan-East Asia Network of Exchange for Students and Youths (JENESYS) programme in Tokyo from 12-19 December 2017.
This programme which focus on Science and Technology aims to promote mutual trust and understanding among the people of Japan and participating countries and regions so as to build a basis for future friendship and cooperation; promote a global understanding of Japan’s society, history, diverse culture, politics and diplomatic relations.
