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 [...]

Thermo Catalytic decomposition of methane on Ni/SiO2 catalyst into pure hydrogen and carbon nanotubes

Sarashwat S., Pant K.K., IIT Delhi, IN

The current methods of producing hydrogen are based on steam methane reforming (SMR), coal gasification, electrolysis, biomass gasification and thermochemical processes A comparison between the cost of hydrogen production from renewable energy, and fossil sources, [...]

Fabrication of Structurally Tailored Cobalt Nanowires

Debburman P.K., Kaur D., Pandya D.K., IIT Delhi, IN

we report an interesting observation of effecting structural transition of electrochemically deposited cobalt nanowires with change in aspect ratio of the nanowires. This change can be controlled by the deposition temperature. These nanowires were deposited [...]

Growth of improved ultrathin pristine SnO2 films by electric field modified spray pyrolysis technique

Shikha S., Pandya D.K., Kashyap S.C., Chaudhary S., IIT Delhi, IN

In the present paper, deposition of good quality polycrystalline pristine SnO2 thin films (25-200 nm) at ~ 450C by a modified spray pyrolysis technique is reported.DC electric field is applied during deposition to improve growth [...]

Structural and magnetic Properties of electrochemically grown Co-Fe and Ni-Fe alloy nanowire arrays

Pandya D.K., Kaur D., Chaudhary S., Kashyap S.C., IIT Delhi, IN

Magnetic nanowires are of immense importance in ultrahigh density magnetic storage media, micromagnetic sensors in read heads and spintronics devices. The nanowires of binary alloys of ferromagnetic metals like Co, Ni and Fe are particularly [...]

Carbon Nanotubes as Machine Elements – A Critical Assessment

Rao P.V.M., Singh M., Jain V., IIT Delhi, IN

Gears, Bearings, Springs, Beams etc. are some of the commonly used machine elements used build machines and mechanical systems. Carbon nanotube can be used as these machine tool elements when building nano-machines or nanomechanical systems [...]

Solid Modeling of Nanoscale Artifacts

Rao P.V.M., Sharma M., Venugopal R., IIT Delhi, IN

Solid modeling involves creation and manipulation of complete and unambiguous mathematical representations of 3-D objects. The purpose of such representation is to provide tools for visualization, calculation of geometric properties and realization by design and [...]
