TCAD AC analysis of Gate Electrode Workfunction Engineering Silicon Nanowire MOSFET for High Frequency Applications

Gupta N., Kumar A., Chaujar R., Delhi Technological University, IN

In this paper, we present the quantitative investigation of the high frequency performance of Gate Electrode Workfunction Engineered Si-Nanowire (GEWE-SiNW) MOSFET up to THz and compared with its conventional counterparts using device simulators: ATLAS and [...]

Synthesis of Nanostructured Calcium Silicate Hydrates

Kumar A., Scrivener K., Bowen P., LTP, EPFL, Switzerland, CH

Cementitious material contribute to about 5-8% of total world Carbon emission per year. Calcium Silicate Hydrates (C-S-H) is the main product of hydrated Portland cements. A better understanding of its kinetics, growth mechanism and atomic [...]

Toxicity of Titanium Dioxide Nanoparticles on Growth Kinetics of Activated Biomass

Das P., Bagdiya N., Kumar A., IIT Delhi, IN

The objective of this study was to study the effect of titanium dioxide (TiO2) NPs on growth kinetic parameters of aerobic sludge bacteria. TiO2 NPs (2 mg/L and 20 mg/L concentrations) were exposed to activated [...]

Voltage Control Of A 3-Ø Self – Excited Induction Generators Using TSC (Thyristor Switched Capacitance)

Kumar A., Chaubey A., Infosys Limited, IN

An induction generator requires reactive power to set up and sustain magnetization and hence generates power. In grid connected induction generators this requirement is met by the grid, which unnecessarily burdens the grid and in [...]

Characterization of Nanostructured Phenolic and Epoxy Composites Under Pulse Laser Degradation

Young S., Kumar A., Ludwick A., Aglan H., Tuskegee University, US

Phenolic and epoxy nanocomposites were fabricated and exposed to pulsed laser. The nanoreinforcements were alumina nanofibers (ANF) and multi-walled carbon nanotubes (MWCNT). The loading of the nanoreinforcement was kept the same for both the epoxy [...]

Enhanced Biodegradation of 2,3,4,5,6-pentachlorocyclohexan-1-ol — a b-HCH Metabolite — in the Presence of a and g-HCH Isomers by Pseudomonas aeruginosa ITRC-5

Singh A., Kumar A., Misra K., Rice University, US

Chlorinated insecticide hexachlorocyclohexane (HCH), which is still used in many countries in agriculture and forestry, leads to environmental problems. HCH consists of a mixture of four isomers: a-, b-, g-, and d. Efforts have been [...]

Catalyst assisted zinc oxide nanowires for gas sensors

Joshi R.K., Kumar A., University of South Florida, US

We present the room temperature detection of 100 ppm carbon monoxide using metal ( Pd and Au) decorated Zinc Oxide (ZnO) nanowires. Zin oxide nanowires were grown via Vapor Liquid Solid method whreas the palladium [...]

Comparative Study Of Effect Of Various Reducing Agents On Size And Shapes Of Gold Nanoparticles

Kumar A., Dhawan N., Stanford University, US

Nanoparticles have attracted considerable interest because of their unique optical, electromagnetic and catalytic properties that differ from bulk ones. The origin of these properties is their large surface to volume ratio and from the coherent [...]

Studies on Carbon Nanotubes – Polyaniline Based Composites

Lal C., Kumar A., Kumar S., Kumar A., Kumar S., Gupta T.K., National Physical Laboratory (NPL), IN

ABSTRACT-: Carbon Nanotubes (CNTs) have become leading material for tremendous strategic applications. We have prepared CNT composites with the Polyaniline by solvent and powder methodology. The adhesion, alignment and the effect of composite nature have [...]
