Ultrasonically sprayed nanostructured SnO2 thin films for highly sensitive hydrogen sensing

Patil L.A., Pratap College Amalner, IN

Nanostructured SnO2 thin films were prepared by ultrasonic spray pyrolysis technique. The aerosol produced by nozzle was sprayed on glass substrate heated at 150oC. The sensing performance of the films was tested for various gases [...]

Violet-Blue Emission From TiO2/SWCNT Hybrid Structure Synthesized by a Simple Chemical Route

Paul R., Kumbhakar P., Mitra A.K., NIT Durgapur India, IN

Using a lucid wet chemical process under room temperature, titania nanocrystallites of average size 5 nm have been adhered to the surfaces of SWCNT bundles. The hybrid structure has been characterized by high resolution transmission [...]

Enhanced Field Emission properties of Titanium decorated Multiwalled Carbon Nanotubes

Sharma H., Kaushik V., Shukla A.K., Vankar V.D., Indian Institute of Technology Delhi, IN

we report the role of Ti on the growth and field emission properties of multiwalled carbon nanotubes (MWCNTs), prepared by microwave plasma enhanced chemical vapour deposition technique (MPECVD). First set of studies were carried out [...]

Electron irradiation induced stuructural changes in nickel nanorods encapsulated in carbon nanotubes

Kulshrestha N., Hazra K.S., Roy S., Bajpai R., Mohapatra D.R., Misra D.S., Indian Institute of Technology - Bombay, IN

Nickel nanorods encapsulated inside the multiwalled carbon nanotubes were prepared using MPCVD technique. As prepared tubes encapsulating nickel were investigated by SEM, XRD and HRTEM. HRTEM study of these tubes exhibits long, good crystalline nickel [...]

Effect of Position and Orientation of Stone-Wales Defects on the Fracture Behavior of a Zigzag Single-Walled Carbon Nanotube

Talukdar K., Mitra A.K., NIT Durgapur India, IN

A (10, 0) SWCNT of length 42.59 Å and aspect ratio 10.9 is studied by Molecular Dynamics (MD) simulation both in perfect condition and also with one, two, three or four SW defects introduced into [...]

Magnetic properties of Sputter deposited and magnetically annealed IrMn/CoFeB nanometric bilayers for exchange biased magnetic tunnel junctions

Fulara H., Raju M., Chaudhary S., Kashyap S.C., Pandya D.K., Inidan Institute of Technology Delhi, IN

The work relates to the exploring the means of controlling the coercivities of the ferromagnetic thin films in a Magnetic Tunnel Junction Stack. Exchange bias route is a very powerful route in achieving this task. [...]

The SURVISMETER – a Green Technology in Service

Singh M., Bhanumati S., Shukla A., Shukla S.S., Shukla A., Shukla S.S., University of Delhi, IN

Viscosity is a measure of stickiness and the reverse is fluidity. It is a valuable data for all liquids in the oil, lubricant, paint, polish, food, beverage, cosmetic, biosolvents, drugs and pharma, polymer, nanomaterials, and [...]

Non bacterial way of production of alcohols and biofuel

Gorakavi P.K., Gorakavi P.K., University college of Technology, Osmania University, IN

Biofuel which is currently being produced through a variety of bacterial uses can be replaced by a much more faster and economical process of production which involves production in laboratory with ot using metabolism. This [...]

Non Bacterial Way for Production of Biofuel for Jet Engines

Gorakavi P.K., Osmania University, IN

Production of a biofuel for jet engines is a priority research topic. Construction of similar chemical composition as that of the existing jet fuels is of absolute requirement. A similar production technique of producing the [...]

Transesterification by Reactive distillation for characterisation and synthesis of Biodiesel

Sapkal R.S., Sapkal V.S., Sapkal R.S., Sapkal V.S., Raut N.B., Shinde G.B., University of Pune, IN

The awareness in alternative fuels has increased dramatically in recent years due to the rising cost and the environmental concerns related to fossil fuels use. Biodiesel represents a more environmentally friendly and cost-effective fuel produced [...]
