Assoc Prof Alfred Tok Iing Yoong1) Carbon-based Field-Effect Transistor Sensors The biosensors market, which is currently at USD 9.9 billion, is expected to reach USD 18.9 billion in 2019 (GIA Report, 2014) propelled by the growing population and health issues. Our group capitalizes on this emergent market and researches on disposable and low-cost sensor suitable for real-time sensing in field conditions. Our group focuses on sensors for biological and gas detection applications. 2) Synthesis of Nanostructured Materials using Atomic Layer Deposition (ALD) Atomic layer deposition (ALD) has evolved to be a unique tool for nanotechnology with atomic level control of the depositions, 3D conformity and homogeneity. Film depositions can be realized for complex non-planar topographies for a wide range of applications such as energy conversion and storage, nanoparticle catalysts, nanostructures for drug delivery, gas separations, sensing, and photonic applications. Our group focuses on ALD materials for solar cell, hydrogen generation and smart window applications. 3) Hard & Tough Materials for Ballistic Protection Application The next generation of military vehicular and soldier system requires light-weight materials with high strength-to-weight ratio. Our research focuses on the synthesis and densification of nanostructured materials & desired composite architecture to significantly raise the ballistic protection capability. The B-C-N-O group of compounds are potential candidates to form novel materials for ballistic protection application as they inherent the unique properties from both boron nitride and boron carbide which are known for their light weight, high hardness, low friction coefficient and high wear resistance. Prof Tok leads a team of collaborators in armour material research ranging from high temperature synthesis of novel superhard materials and consolidation by state-of-the-art Spark Plasma Sintering to advanced characterisation techniques such as depth of penetration test using Two-Stage Light-Gas Gun. 4) Institute for Sports Research Our group is involved in the Institute for Sports Research, working on the damping property of midsoles which is based on carbon nanotube (CNT). CNT’s high aspect ratios (length/diameter) is particularly desirable for mechanical reinforcement, and it is found that the vertical aligned (VA)CNTs perform well in damping, to dissipate the energy absorbed under compression (Figure 7). Our present job is to tune the damping property of VACNT by adjusting the length, diameter and area density etc. parameters and try to reinforce the polymer with VACNT to fabricate midsole material with better cushion property. 5) NRF-CREATE In accordance with the objectives of the Energy Thrust Program of the NRF-CREATE Project, our group is focused on the design and synthesis of highly functional nanomaterials, which enables energy harvesting and conservation. Recently, novel graphene oxide synthesized nanoballs and nanoflowers were synthesized. These exhibit potentials for supercapacitors and energy applications. In general, these activities results in above 50 publications, 17 patent applications and projects discussions with companies regarding commercialization possibilities.

Asst Prof Amir AbdolvandAdvanced photonics relies largely on our ability to “engineer” and “shape” the chemical and geometrical properties of glass as its main building block. In fibre optics, these have resulted in the emergence of speciality optical fibres. These are novel optical fibres with high technological and scientific impact, designed either through materials considerations, e.g. optical fibres from speciality glasses, and/or through structural considerations, e.g. Photonic Crystal Fibres (PCFs)—first proposed by Philip Russell in 1991. In a broad sense, the primary focus of our research at COFT and LUCI is on the design, fabrication and applications of PCFs for controlled laser-matter interaction. Our activities encompass both experimental and theoretical work on topics ranging from fundamental studies of the interaction of electromagnetic waves with matter, and spectroscopy to the creation of new light sources for applications. At the heart of these studies and applications are the PCFs. These are emerging as ideal platforms for controlled interaction of light and matter, e.g. gases, liquids, solids or plasmas, hosted in PCFs. We tailor PCFs’ characteristics such as guidance window, geometry or dispersion, to match our experimental requirements or to improve PCFs’ performance.
