Energy-Based Molecular Fragmentation Methods
The review covers the state-of-the-art of energy-based molecular fragmentation methods of which both authors have made significant contributions. The defining characteristic of an energy-based molecular fragmentation method is that the molecule (also cluster of molecules, or liquid or solid) is broken up into a set of relatively small molecular fragments in such a way that the electronic energy of the full system is given by a simple linear combination of the energies of these fragment molecules. The successful application of the method enables accurate solution of the Schrodinger equation for molecules the size of proteins. Reported by Associate Professor Ryan P A BETTENS group.

“Temporal full-color tuning through non-steady-state upconversion”
Assoc Professor LIU Xiaogang group reported that producing luminescence materials with tunable emission colors that can be applied for high quality displays is a very difficult task. Especially, it is challenging to develop light-responsive materials that are possible to produce any desired colors in a broad spectrum range on demand through the use of a simple external stimulus. Now they have achieved this goal by exploiting a novel concept, non-steady-state upconversion, based on the design and synthesis of lanthanide-doped core-shell upconversion nanomaterials. The emission color of the core-shell upconversion nanocrystals was turned by adjusting the pulse width and intensity of near-infrared laser excitations. R. Deng, F. Qin, R. Chen, W. Huang, M.

The 8th Singapore International Chemistry Conference (SICC-8) 14th - 17th Dec 2014, University Town, NUS
SICC-8, which attracted close to 400 participants, including 180 foreign delegates, was jointly organized by the Department of Chemistry, NUS, and the Singapore National Institute of Chemistry (SNIC). With over 150 oral presentations, including 6 plenary and 16 keynote presentations given by highly-established scientists, and 200 poster presentations, the conference was a huge success with a high level of scientific discourse!

Prof Loh Kian Ping also won the National Research Foundation Investigatorship Award.
Building Bonds in Chemistry @ Kyoto
The inaugural International Collaborative and Cooperative Chemistry Symposium (ICCCS) was initiated and organized by NUS chemistry in 2010. This year, ICCCS-5 shifted to Kyoto. Prof Loh Kian Ping, Prof Lu Yixin, A/P Liu Xiaogang, Assist Prof Ang Wee Han, and Assist Prof Zhao Yu attended the symposium, among 40 professors from 8 universities in the region. Many exciting scientific advances in chemical sciences were presented, and the delegates had thoroughly enjoyed scientific interactions, as well as renewed their friendship during the symposium.
Illuminating test measures fat in milk
Prof. Chang Young-Tae’s group reported the first fluorescent milk fat sensor (Chem Comm, 2014, 50, 10398-10410). It exhibits magnificent, yet selective turn-on feature towards fat molecules in complicated milk matrix, through the disaggregation-induced emission mechanism. Further construction of a handy fluorescence milk fat detector provides a convenient rapid tool to measure fat amount quantitatively. This discovery may greatly help enhance the milk quality control process. This work was highlighted in Chemistry World: http://www.rsc.org/chemistryworld/2014/08/milk-fat-fluorescent-probe
The Department has just established a research collaboration with its counterpart at the King Fahd University of Petroleum & Minerals (KFUPM), Dhahran, Saudi Arabia. Under the collaboration, six projects involving faculty members from both departments will receive funding of S$1.1 million over three years. From our department, Professors Lu Yixin, Richard Wong and Lee Hian Kee, and Associate Professors Chuah Gaik Khuan, Han Vinh Hyunh and Stephan Jaenicke will be involved in the collaboration with their colleagues from KFUPM on environmental analytical chemistry, catalysis, nanostructured materials and computational electrochemistry.
Professor WONG Ming Wah, Richard has joined the editorial board of Australian Journal of Chemistry as Associate Editor for 3 years.
Congratulate Mr Fung Fun Man for being the 1st Singaporean and 3rd Asian to be elected into the IChO (International Chemistry Olympiad) Steering Committee.
