Congratulation to Prof. Ding Jun and his team across FE departments on their successful securing a 3-million, NUS strategic research program to develop 3D printing technology.
Congratulations to Dr. R.P. Rao, D. Safanama and A/P Stefan Adams for winning the best poster award for their poster “Ceramic electrolytes for lithium sulfur semi-flow rechargeable batteries” at the 6th MRS-Singapore Conference on Advanced Materials and “Chemistry of Energy Conversion” workshop, held at NTU from 22nd-24th July, 2014. There the authors first time demonstrated rechargeable semi-flow sulfur batteries of high specific capacity making innovative use of fast-ion conducting solids Li6PS5X (X=Cl,Br) and Li10GeP2S12.
A/Prof Daniel Chua is appointed Assistant Dean to the Office of Vice-Dean (Undergraduate Programs) with retrospective effect from 1 July 2014.
A warm welcome to MSE in the new academic year! Prof John Wang will like to invite all new and existing students and staff in the Department of Materials Science & Engineering to our Department's Welcome Tea, for the start of the new academic year 2014/15. The Tea session will be held on 13th August 2014, 12 noon @ EA Auditorium.
Our heartiest congratulations to our MSE Graduating Class of 2014. We wish them the best in their future endeavours.
A MSE delegation consisting of Prof. John Wang, the head of department, Prof. Ding Jun, A/P Xue Junmin, Dr. Chiu Cheng Hsin and Dr. Wang Qing, visited a few top universities in China during the week of 2-6 June. Education and research were extensively discussed with colleagues in Tongji Univ., Fudan Univ., Nanjing Univ., Nanjing Tech Univ. and USTC during the visit. Collaboration possibilities at department level and among individuals were explored.
Dr. Wang Qing is promoted to Associate Professor with tenure, effective July 1, 2014. His research can be found from here.
Simultaneous control of the microstructure, crystallographic structure and magnetic properties of L10 FePt films is the main blocks for the application for heating assisted magnetic recording media. Although L10 FePt (001) films with high magnetic anisotropy and small isolated grains have been synthesized in the past few years using MgO underlayer, large opening-up of in-plane hysteresis loop (large noise) and low grain aspect ratio (low signal) made it unsuitable for ultra-high density magnetic recording (beyond 1 Tbits/in2). Assoc. Prof. Jing-Sheng CHEN’s group has invented a new media structure which utilises TiON or TiN-oxide composite (001) textured underlayers. L10 FePt (001) films with high magnetic anisotropy, small grain size and small opening-up of in-plane hysteresis loop, as shown in the figure below, were synthesized with these conductive intermediate layers that have a larger surface energy and smaller interfacial energy. The conductive intermediate layers can be fabricated by industry preferred direct-current sputtering. This work is done by Assoc. Prof. Jing-Sheng CHEN’s research group and has published in Applied Physics Express, 6, 075502 (2013). The research is financially supported by Seagate. Recently, Seagate has filled three NUS-owned patents based on this work (US 61/706314; 61/706317; 61/733202) read more
Carbon segregation using metal substrates has been given increasing attention as an alternative graphene growth method due to its reduced temperature. However, not every metal behaves in the same manner during the process, hence it is imperative to study their effectiveness when using this growth method. In this paper, few-layer graphene was fabricated on metal substrates with an energetic carbon source supplied by pulsed laser deposition. The ability of Ni, Cu, Co and Fe thin films to form graphene through segregation was investigated. Graphene was fabricated on Ni and absent in Cu, Co and Fe under a specific cooling profile. This was attributed to either low solubility of carbon in Cu and Fe or low carbon diffusion coefficient in Co. However, by adjusting the cooling rate to cater to the carbon diffusion coefficient of Co, low defect few-layer graphene with large substrate coverage was obtained. The results showed that when using PLD, a metal with sufficient carbon solubility is desired over its catalytic ability. The reasons behind the observed phenomena are also discussed read more
Dual-Layer Protections of Quantum Dots for Stable and Targeted Bioimaging Dr Zhang Yu, from John Wang’s research group, together with collaborators in MSE (Happy Tan, Benedict You-wei Hsu, and Zhengchun Yang), IMRE (Li Xu, Yuan-gang Zheng and Siew Yee Wong), Johns Hopkins Singapore (Miao Wang and Alex Yuang-chi Chang), NUS Yong Loo Lin School of Medicine (Mahesh Choolani), have developed PEOlated Micelle/Silica Dual-Layer Protections of Quantum Dots for Stable and Targeted Bioimaging. The work has been published in Chemistry of Materials, 25 (15) 2013, pp 2976–2985 DOI: 10.1021/cm4005618. Further details: http://pubs.acs.org/doi/abs/10.1021/cm4005618 read more
