Many nanofabrication methods based on scanning probe microscopy have been developed during the last decades. Local anodic oxidation (LAO) is one of such methods: Upon application of an electric field between tip and surface under ambient conditions, oxide patterning with nanometer-scale resolution can be performed with good control of dimensions and placement. LAO through the non-contact mode o...

An off-lattice Monte-Carlo simulation was used to study non-isotropic heat conduction in aligned carbon nanotube (CNT)-polymer nanocomposites (PNCs) focusing on the effects of CNT-CNT contact and CNT distribution on heat transfer. CNT-CNT contact significantly affects the effective transport properties of PNCs, including anisotropy ratios, but has not been studied extensively either theoretical...

CO2 capture and storage is a potential means to alleviate global warming and ocean acidification. Herein, CO2 capture with various functionalized graphanes and the effects of functional groups are investigated by density functional theory (DFT). Our results show that CO2 adsorbs weakly on a bare graphane sheet, and absorbs slightly better when functionalized with P-substituted graphane, and inc...

We report the fabrication and improved properties of crosslinked polyarylene ether nitrile (CPEN) interpenetrating with a zinc ion bridged graphene sheet (GS) and carbon nanotube (CNT) network (GS-Zn-CNT) (CPEN/GS-Zn-CNT). Graphene oxide (GO) and acidulated CNT were firstly prepared and then coordinated with zinc ions to form the zinc ion bridged GO and CNT network (GO-Zn-CNT). The mass ratio o...

Carbon nanotubes have unique properties like high stability, high surface to mass ratio and so on which make them suitable for medicinal purpose applications. Treatment of cancer by organoplatinum agents like Cisplatin has become unresponsive in most cases due to low distribution of drug in biological fluids, inability of drug to cross cellular membranes and low stability in biological environm...

The recent application of nanotechnology to structural materials is a promising way to produce new strong materials that exceed current limitations. Grain-size refinement is considered as one of the most effective strengthening methods of materials. At the same time, the addition of carbon nanotubes (CNTs) in a material is known to be more effective than conventional reinforcements. Here, CNT/C...

A hierarchical framework is proposed to address the issues of modeling different type of words in keyword spotting (KWS). Keyword models are built at various levels according to the availability of training set resources for each individual word. The proposed approach improves the performance of KWS even when no training speech is available for the keywords. It also suggests an easier way to co...
