New chemistry for longer-lived batteries

28 April, 2014

US researchers have developed a new design mechanism that could allow batteries to last 30-50 years.


Unlocking secrets of new solar material

24 April, 2014

Researchers at the US Energy Department's National Renewable Energy Laboratory (NREL) are analysing a new solar material that has the same crystal structure as a mineral first found in the Ural Mountains in 1839. The material, perovskite, is extremely efficient.

To ensure that power electronic components are reliably protected from the effects of non-permissible operating conditions, fast and reliable error detection and effective protective measures are essential.


Li-S batteries for electric vehicles

17 April, 2014

PNNL researchers have packed lithium-sulfur batteries with a unique powdery nanomaterial that helps them last longer.


New material absorbs sun's heat and releases it on demand

14 April, 2014 by David Chandler

A team at MIT and Harvard University has come up with a material that can absorb the sun's heat and store that energy in chemical form, ready to be released again on demand.

The LS03-R2S AC or DC input series (high-voltage DC-DC) is offered in a small 35 x 27 x 11 mm size with open frame construction. The series is designed for use in less demanding EMC applications.


Analog Devices ADuM124x dual-channel digital isolators

31 March, 2014 | Supplied by: Mouser Electronics (Hong Kong) Ltd

Analog Devices' ADuM124x dual-channel digital isolators are micropower devices based on iCoupler technology. Combining high-speed CMOS and monolithic air core transformer technologies, the isolation components are said to provide high performance yet consume low power.


Surge protection 101

26 March, 2014 by Mike Smyth, specialist technical writer

Surges or sudden bursts of voltage and current can be disastrous to electronic and electrical equipment and to the cables feeding them. Surge protectors limit the voltage getting through to equipment and often the feed lines, either by blocking it or diverting to earth voltages above a predetermined level.


A breathing battery

19 March, 2014

Most electrical vehicles won't take you farther than 160 km on one charge. Japanese researchers are working towards increasing the range to 480 km or more with the help of a breathing battery that could one day replace the lithium-ion technology of today's EVs.
