College Park MD (SPX) Apr 22, 2020 - Lithium ion batteries have already become an integral part of our everyday life. However, our energy-hungry society demands longer life, faster charging, and lighter batteries for a variety of applications from electric vehicles to portable electronics, including lightening the load a soldier carries as numerous electronics become adopted by the Army.

Can we get closer to such lighter and faster-charging batteries? The current generation of lithium ion batteries uses graphite as an anode... Читать дальше...

Philadelphia PA (SPX) Apr 22, 2020 - When electronics need their own power sources, there are two basic options: batteries and harvesters. Batteries store energy internally, but are therefore heavy and have a limited supply. Harvesters, such as solar panels, collect energy from their environments. This gets around some of the downsides of batteries but introduces new ones, in that they can only operate in certain conditions and can't turn that energy into useful power very quickly.

Joensuu, Finland (SPX) Apr 22, 2020 - Researchers at the University of Eastern Finland have developed a new hybrid material of mesoporous silicon microparticles and carbon nanotubes that can improve the performance of silicon in Li-ion batteries. Advances in battery technology are essential for sustainable development and for achieving climate neutrality.

States and companies worldwide are eagerly looking for new and sustainable technologies to achieve climate neutrality in every sector of society... Читать дальше...

West Lafayette IN (SPX) Apr 24, 2020 - New battery technology involving microwaves may provide an avenue for renewable energy conversion and storage.

Purdue University researchers created a technique to turn waste polyethylene terephthalate, one of the most recyclable polymers, into components of batteries.

New York NY (SPX) Apr 24, 2020 - Using electronic devices for too long can cause them to overheat, which might slow them down, damage their components or even make them explode or catch fire. Now, researchers reporting in ACS' Nano Letters have developed a hydrogel that can both cool down electronics, such as cell phone batteries, and convert their waste heat into electricity.

Some components of electronic devices, including batteries, light-emitting diodes (known as LEDs) and computer microprocessors, generate heat during operation. Читать дальше...

Brisbane, Australia (SPX) Apr 22, 2020 - QUT researchers have proposed the design of a new carbon nanostructure made from diamond nanothreads that could one day be used for mechanical energy storage, wearable technologies, and biomedical applications.

Dr Haifei Zhan, from the QUT Centre for Materials Science, and his colleagues successfully modelled the mechanical energy storage and release capabilities of a diamond nanothread (DNT) bundle - a collection of ultrathin one-dimensional carbon threads... Читать дальше...

Given the departures of every significant defensive free agent and all the releases, you knew the Panthers were going to lean heavily toward defense during the 2020 NFL Draft. They did more than lean, they went exclusively on that side of the ball. By using their seventh-rounder on Florida International cornerback Stantley Thomas-Oliver, the Panthers [more]

Research Triangle Park NC (SPX) Apr 23, 2020 - Researchers say a new discovery on a U.S. Army project for optoelectronic devices could help make optical fiber communications more energy efficient.

The University of Pennsylvania, Peking University and Massachusetts Institute of Technology worked on a project funded, in part by the Army Research Office, which is an element of U.S. Army Combat Capabilities Development Command's Army Research Laboratory. The research sought to develop a new design... Читать дальше...

Canberra, Australia (SPX) Apr 23, 2020 - Galaxies grow large by eating their smaller neighbours, new research reveals.

Exactly how massive galaxies attain their size is poorly understood, not least because they swell over billions of years. But now a combination of observation and modelling from researchers led by Dr Anshu Gupta from Australia's ARC Centre of Excellence for All Sky Astrophysics in 3 Dimensions (ASTRO 3D) has provided a vital clue.
