Evidence for a direct interaction between poly-dispersed single-wall carbon nanotubes and murine erythrocytes resulting in in vitro and in vivo cytotoxicity

Sachar S., Saxena R.K., Jawaharlal Nehru University, IN

Single wall Carbon Nanotubes (SWCNTs) are highly hydrophobic in nature and agglomerate strongly. Treatment of SWCNTs with sulphuric and nitric acid (acid functionalization) results in the introduction of carboxy and sulfonate groups on SWCNTs and [...]

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 [...]

Orally Delivered Polymeric nanoparticles of Lopinavir: Development and Statistical optimization, in vitro and ex vivo studies

Joshi G., Sawant K.K., M S University of Baroda, IN

Nanoparticles (NPs) have been extensively studied for oral drug delivery. NPs are taken up intact by M cells of peyer’s patches of gut associated lymphoid tissue (GALT) followed by its systemic circulation thereby preventing first [...]

A Novel Single Step Method of Synthesizing Large Unilamellar Liposomes for Biomedical Applications

Phapal S.M., Sunthar P., Indian Institute of Technology - Bombay, IN

We have investigated various coacervation techniques for liposome synthesis. The aim is to study various local mixing conditions and their effect on the size of liposomes formed. To control the extent of mixing, four different [...]

Physics based Analytical Model for a Pocket Doped p-n-p-n Tunnel Field Effect Transistor

Narang R., Saxena M., Gupta M., Gupta R.S., Gupta M., Gupta R.S., University of Delhi, South Campus, IN

Tunnel FET working on the principle of band-to-band tunneling mechanism has come up as a promising candidate with advantages of going below the limitation of 60mV/decade sub-threshold slope, and lower leakage current and thus capable [...]

Modeling and Analysis of MOS Capacitor Controlled by Independent Double Gates

Thakur P.K., Mahapatra S., Indian Institute of Science, Bangalore, IN

This paper, for the first time, explores the charcatersictics of MOS capacitor controlled by independent double gates by numerical simulation and analytical modeling for its possible use in RF circuit design as a varactor. By [...]

Analytical Drain Current Model for Damaged Gate All Around (GAA) MOSFET Including Quantum and Velocity Overshoot Effects

Gautam R., Saxena M., Gupta M., Gupta R.S., Gupta M., Gupta R.S., University of Delhi, South Campus, IN

The Cylindrical Gate All Around (GAA) Nanowire MOSFET exhibits strong drive currents and reduced short channel effects due to enhanced gate control and high surface quality of NW channels [1]. Apart from short channel immunity, [...]

Switching and Release Dynamics of an Electrostatically Actuated MEMS Switch under the influence of Squeeze-film Damping

Shekhar S., Vinoy K.J., Ananthasuresh G.K., Indian Institute of Science, IN

This paper reports analytical modeling, simulation and experimental validation for switching and release times of an electrostatically actuated micromachined switch. Presented work is an extension of our earlier work [1] that analytically argued, and numerically [...]

Linearity evaluation of Silicon Nanowire Surrounding Gate MOSFET for high performance ULSI applications

Aggarwal N., Sikka K., Gupta I., Chaujar R., Delhi Technological University, IN

The inspiration of this work is that the search for high performance ICs has led to scaling of MOSFETs down to sub-50nm regime and thus Silicon Nanowire (SNW) MOSFETs offer a promising solution for realizing [...]

Heat transfer behaviour of Nanofluids

Nayak A.K., Kulkarni P.P., Singh R.K., Vijayan P.K., Bhabha Atomic Research Centre, IN

Nanofluids are stable colloidal suspensions of nanoparticles, nanofibers, or nanocomposites in common base fluids, These nanofluids can possess properties that are substantially different from their parent materials. Study on nanofluids heat transfer is rather a [...]
