Scientists use Nanotechnology to resist wear

In a recently published study, scientists at the Indian Institute of Science, Bangalore, are addressing one of the biggest challenges faced by many appliances - wear and friction due to usage. Wear and friction affects the lifetime of industrial equipment, which directly correlates with the profitability of the business. The teams of researchers, led by Prof. M.S. Bobji at the Department of Mechanical Engineering are now experimenting with alumina based nanocomposite coating for wear resistance.

Living on the edge – shape affects cell movement

You may have thought that the cells in your body are stationary, sitting in fixed locations and forming the tissues and organs of your body. Research has shown however that the cells within the body actually do a lot of moving. Cells move for a variety of reasons - during wound healing when healthy cells around a damaged area move to cover up the wound, or in diseases such as cancer where cancerous cells spread from organ to organ.

An Indian Cyrocooler for Space Applications

Have you ever wondered how the images taken by the Hubble Space Telescope can reveal galaxies and stars which are many light years away? The Telescope itself is subject to intense cycles of hot and cold as it revolves around the earth, but seldom falters in its performance. The fantastic high resolution images taken by the Hubble telescope have Cryogenic Technology to thank, for keeping their imaging sensors working well.

Bursting droplets give new insights into making fuels better and less polluting

By studying how individual droplets of fuels, loaded with nanoparticles behave, researchers have found a way to extract more energy from fuels and make them less polluting. This is a significant insight because our fossil fuel resources are depleting, and also our usage of available fuels is adversely affecting environment. The study was carried out by researchers from the Department of Mechanical Engineering, Indian Institute of Science, Bengaluru.

A mobile robot that does not slip

Robotic engineers at IISc have designed a wheeled mobile robot that can move in a stable manner on an uneven terrain with minimal slipping. Prof. Ashitava Ghosal from the Department of Mechanical Engineering, Indian Institute of Science, Bangalore and Dr. Tharakeshwar Appala from SSJ Engineering College, Hyderabad have successfully demonstrated a prototype of an “autonomous mobile robot” that can travel in a straight line, make turns and also switch lanes on bumpy terrain, without the risk of falling off and with minimal slip.

Improved solar trackers for better solar energy harvesting

Researchers from the Indian Institute of Science have developed an improved version of a device that can track and orient mirrors, also called heliostats, towards the Sun. These tracking devices are important components of large scale solar thermal power plants, and are not new. But, the new version, developed at the Indian Institute of Science, is lighter, cheaper, remains stable even in strong winds, and of course, is better at tracking the sun.

Virtual reality machines to train endoscopists better

Engineers from the Indian Institute of Science have developed an endoscopy simulator that simulates the effect of physical contact. In the long run, this technology can be made economical and can be used to train endoscopists by providing them an immersive training environment.
