Device That Can Turn Heat Energy to Fuel

Scientists have developed a device that could turn the heat generated by electronics into a usable fuel source, an advance that may help save energy.
The device is a multicomponent, multi layered composite material called a van der Waals Schottky diode.
It converts heat into electricity up to three times more efficiently than silicon - a semiconductor material widely used in the electronics industry.

IRNSS-1H Satellite Launch Unsuccessful

India’s attempt to launch its eighth regional navigation satellite failed. The satellite IRNSS-1H didn’t come out of the heat shield as it should have, though the rocket’s lift off was as planned.
As per ISRO chief A. S. Kiran Kumar, there was no problem in any of the stages. But the heat shield has to separate. And once that happens the satellite gets into the orbit. It got separated internally. But it’s enclosed within the heat shield in the fourth stage.
IRNSS-1H was being sent to space to back up — and mostly replace — the functions of India's first navigation satellite.

New Way to Mix Water and Oil

According to a new study, oily molecules, which normally repel water, can be dissolved in the liquid when the two are squeezed together under extreme pressure.
Understanding the mixing properties could help find ways of replacing expensive and hazardous solvents used in the chemical industry.
