High-Performance dye-sensitized solar cells with various nanostructured materials as counter electrode

Ouyang J., National University of Singapore, SG

Traditionally, Pt prepared by hydrolysis was used as the counter electrode of dye-sensitized solar cells. But the hydrolysis requires a high-temperature process, so that it is not suitable for flexible substrates like plastics. In addition, [...]

We present a polymer-based microfluidic device capable of performing various DNA preparation processes like enzymatic, end repairing, and purification. The system consisted of a disposable polymeric chip and a controlling unit. Mixing chambers, incubation chambers [...]

Xsim: Benchmark Tests for the Unified DG/GAA MOSFET Compact Model

Zhou X., Zhu G.J., Srikanth M.K., Lin S-H, Chen Z.H., Zhang J.B., Wei C.Q., Yan Y.F., Selvakumar R., Nanyang Technological University, SG

This paper presents benchmark tests of the unified compact model (Xsim) for double-gate (DG) and gate-all-around (GAA) silicon-nanowire (SiNW) MOSFETs, which has been developed over the years with the unified regional modeling (URM) approach. The [...]

Transitions Between Epithelial and Mesenchymal States in Microfluidic Platform: Acquisition of Malignant and Stem Cell Traits

Aref A.R., Huang R.Y.J., Kang W., Jing S.W., Thiery J.-P., Kamm R.D., SMART, SG

Epithelial–mesenchymal transition (EMT) is an indispensable mechanism during morphogenesis, as without mesenchymal cells, tissues and organs will never be formed. Transitions between epithelial and mesenchymal states have crucial roles in embryonic development and without EMT, [...]

Hierarchically Branched Gecko Tapes Imprinted Using Porous Alumina Templates

Yee A.H.Y., Lam Y.C., Institute of Materials Research and Engineering, SG

In this work, we show the methodology to fabricate hierarchical nano-structures of various geometrical parameters to mimic closely gecko’s adhesion system. The relevant geometrical parameters investigated are a) the aspect ratio of the fibrils b) [...]

Functionalization of Carbon Nanotubes for Advanced CNT/LCP Nanocomposites

Sahoo N.G., Cheng H.K.F., Li L., Chan S.H., Zhao J., Nanyang Technological University, SG

A novel approach has been made to the chemical functionalization of multi-walled carbon nanotubes (MWCNTs) for developing advanced polymeric nanocomposites with liquid crystalline polymer (LCP). In the approach, we have selectively introduced two types of [...]

Preparation and Characterization of BiFeO3 Nanosystems as Visible Light Driven Photo-degradation of Organic Compounds

Hengky C., Dunn S., Singh V., Loh L., Nanyang Polytechnic, SG

The use of renewable or low energy sources for the degradation of organic pollutants has generated broad interest in both scientific research and potential applications in recent years. Research on semiconductor photocatalysis came sharply into [...]
