In the present work different quality of alumina are taken along with different metals as the starting materials. Different compositions are formulated taking single or combination of metals which are mixed with phenol formaldehyde resin and pressed with a specific pressure of 2000kg/cm2. The bricks are cured at 240°C for 12 hours. Physical, thermal and thermo mechanical properties are evaluated.

Partial Discharge (PD) is characterized by current pulses that appear in high voltage (HV) electrical equipments obtained from ionization process when damaged insulation is submitted to high values of electric. That means ageing and deterioration is mainly occurs due to the presence of partial discharge in an insulator used in the high voltage power equipments.

Core–shell nanoparticles are gaining lots of importance recently due to their exciting applications in different fields like biomedical, pharmaceutical, electronics, catalysis etc. They also show new properties than the single materials when coated one material with other. In this report we studied the preparation and growth kinetics of sulfur nanoparticles as a core in aqueous surfactant ...

Energy requirements for the developing countries like India in particular are met from coal-based thermal power plants. The ash generation has increased to about 131 million tonne during 2010-11and shall continue to grow. Huge amount of coal ash generation creates major problems for their disposal. Primarily, the coal ash is disposed off using either dry or wet disposal scheme.

Electric Railway Traction Drive has been introduced as a solution to the environmental problem caused by the diesel or steam engines. Generally, an AC electrified railway system is supplied with 25kV, 50 Hz AC supply. It is fed to the traction motor after stepping down to three phase, 400 V, 50Hz with the help of a transformer. This magnetically coupled transformer lead to high weight, several ...

Technology Day: IIT Delhi innovators bag National Award for nasal filters A team of IIT Delhi researchers was awarded the Startups National Award 2017 by the Technology Development Board for creating a promising new technology to protect against air pollutants and minimize the risk of respiratory diseases.

The architecture of the 3D IIR frequency planar filter is the building block of cone shaped filter or beam filter for antenna beamforming. Each PPCM essentially implements (1) in real time for a particular spatial location. The straightforward direct-form I implementation of (1) inside each PPCM is described in [14],[6].
