Transfer of asymmetric free-standing TiO2 nanowire films for high efficiency flexible dye-sensitized solar cells

Xue Z., Wang L., Liu B., National University of Singapore, SG

A free-standing TiO2 nanowire thin film was prepared using the doctor-blade method. The film is composed of big and small nanowires on each side. The big nanowires have the functions of weakening adhesion to its [...]

Fabrication of complex three-dimensional multilevel silicon micro- and nano-structures

Azimi S., National University of Singapore, SG

We have developed a new process to fabricate arbitrary-shaped, multilevel, three-dimensional free-standing micro- and nano-structures on bulk silicon using focused high energy proton beam irradiation, followed by electrochemical anodization. We make use of the fact [...]

Mass Production of Metal Oxide Nanoparticle Dispersion for Heat-ray Shielding Application

Shen Z., Soh W., Zhang J., Wang A., Chen J., Chen W., Yun J., Sher D., Chen J., Chen W., NanoMaterials Technology Pte Ltd, SG

A unified approach, HGCP process was applied to produce various metal oxide nanoparticle dispersion with low cost. The process involved achieving instantaneous molecular mixing for metal salts and precipitant reactants by using HGCP reactor to [...]

Unified Regional Approach to High Temperature SOI DC/AC Modeling

Chiah S.B., Zhou X., Chen H-M, Chen Z., Chen H-M, Chen Z., Nanyang Technological University, SG

This paper extends the recent model development [1] to include temperature effect in a range from room temperature to 300C. The extraction of the temperature coefficients used in the model and the prediction of the [...]

A Simplified Model for Dynamic Depletion in Doped UTB-SOI/DG-FinFETs

Zhou X., Chiah S.B., Nanyang Technological University, SG

Compact modeling for doped-body MOSFETs, such as ultra-thin body (UTB) SOI and double-gate (DG) FinFETs, represents the most challenging task since it involves the Poisson’s solution with two boundary conditions, which is not available when [...]

An analytical 2DEG model considering the two lowest subbands

Zhang J., Zhou X., NTU singapore, SG

A general 2DEG density model that considers the lowest two subbands (subband split) as well as the subthrehold region is derived and validated through comparison with the numerical (exact) solutions. Good agreement is obtained between [...]

Capture of circulating tumor cells (CTCs) using a novel micro-device

Ranjan S., Yong Z., National University of Singapore, SG

Circulating tumor cells (CTCs) are metastatic cells that are detached from a tumor and are found in the blood of cancer patients. The presence of CTCs in the blood indicates the metastatic stage of cancer, [...]

Polymer microfluidic chip with embedded CNTs for DNA sample preparation

Khuntontong P., Chan J.X., Gong M., Wang Z.P., Singapore Institute of Manufacturing Technology, SG

We present a polymer-based microfluidic chip which has deposited carbon nanotubes (CNTs) onto the microchannel. The chip is capable of performing DNA preparation process like restriction enzyme digestion and ligation of DNA. The advantage of [...]

Novel three-dimensional porous film for single-cell microarray applications

Ranjan S., Yong Z., National University of Singapore, SG

Cell-based studies yield data averaged over a large number of cells which overlook the rich information that can possibly be obtained when cells are studied individually. For this reason, much emphasis has been placed over [...]
