Sandia National Laboratories has developed a polymer that helps prevents fires caused by ageing solar panel connectors. The problem is that corrosion inside such connectors can cause heating through increased series resistance, and eventually arcing. “As solar panels become more efficient, they’re able to produce more power,” said Sandia researcher Kenny Armijo, who has spent ...

Dublin-based Benetel has integrated its Radio Unit with Radisys’ 5G NR OpenRAN software for OpenRAN deployments in communication, industrial and private networks. The two companies have also made a licensing agreement for Radisys’ LTE software to allow its distribution with Benetel’s eNodeB radio platforms. Pre-integrated, the hardware and software can be deployed in both non-standalone ...

Combing graphene with a metal-organic framework can produce a highly-porous and conductive electrode for supercapacitors, according to the Technical University Munich (TUM), which has built a device to prove it, that can challenge some battery technologies for specific energy capacity. “The new energy storage device does not only attain an energy density of up to 73Wh/kg, ...

US engineers and physicists have identified conditions where independent robots will spontaneously act collaboratively – much as flocks of starlings form shapes in the air. It does not cover every situation nor every type of independently-acting entity, but posits that entities with sufficiently messy dynamics will spontaneously find ‘low rattling’ states. “Rattling is when matter ...

With less that a week to go, there is some real information on how companies should deal with the consequences of Brexit. Sadly, it is only a summary of the main 1,200 page document, which remains unpublished at the time of writing. The UK government ‘UK-EU trade and cooperation agreement summary’ is here. Less than ...

Researchers in Saudi Arabia have demonstrated white light emission from a phosphor-less LED. Generally, ‘white’ LEDs have a blue-emitting die topped with phosphors that convert some of that blue to broad-spectrum amber – which combined with the residual blue is seen by humans as cool white. Adding a red-emitting phosphor in the mix produces warm white ...

Efficient Power Conversion (EPC) is aiming at USB chargers and thin point-of-load converters with a 40V 3mΩ enhancement-mode GaN power transistor. Called EPC2055 it is a “good example of the rapid evolution of GaN FET technology”, according to company founder and CEO According to Alex Lidow. This 40 volt device offers both smaller size and reduced ...

While graphene has some amazing physical, optical and mechanical properties, its lack of a natural bandgap limits its use in electronics. Methods of varying complexity have been found to add bandgaps, and now there is another tool in the box – a chemical whose molecules self-assemble into an evenly-spaced flat lattice as they bond down ...
