Our heartiest congratulations to our MSE Class of 2018. We wish them the best in their future endeavours.
Continuously tune the work function of conductors in a wide range for the first time. Ouyang Jianyong and his team developed a novel method to continuously tune the work function of ITO, Ag, Au, PEDOT:PSS and rGO in a wide range by using controlling the ratio of Cu2+ to poly(amido amine) (generation 3) (PAMAM). The mechanism for the work function change is ascribed to the effect of Cu2+ on the interfacial dipole moment between substrates and Cu2+-PAMAM. They also demonstrated its application in high-performance polymer solar cells. This work has been published in Advanced Functional Materials.
Professor Shih Choon Fong, NUS University Professor and former NUS President, has been awarded the Centennial Medal by Harvard University’s Graduate School of Arts and Sciences (GSAS) for his innovative research and leadership in higher education.
A/Prof Tan Swee Ching and his team have successfully developed a new method of optically manipulating metal work function. Work function of a material is typically known to be independent of light intensity based on our present understanding. However, the team has discovered a special case where there is a ‘light-intensity dependent’ change in work function in metal thin films. This work has been published in Science Advances.

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.
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.
