Polymer extracted from seaweed may improve battery performance

brown-algae-kelp

Collaboration between researchers at the Clemson University and the Georgia Institute of Technology resulted with a promising new binder material for lithium-ion battery electrodes. Known as alginate, the material is extracted from common, fast-growing brown algae, and it could boost energy storage, while eliminating the use of toxic compounds now used to manufacture the components. ... »

First optoelectronically active 3D photonic crystal developed

3d-photonic-crystal-led

Previous attempts at making 3D photonic crystals have resulted in devices that are only optically active (they can’t turn electricity to light or vice versa). A group of researchers, led by researchers from the University of Illinois, have managed to develop the first optoelectronically active 3D photonic crystal. The development could enable new advancements for ... »

Lighter and stronger steel needs less than 10 seconds to be processed

flash-bainite-steel-1

A Detroit entrepreneur surprised university engineers when he invented flash processing – a heat-treatment process which lasts only 10 seconds and it makes steel stronger and more shock-absorbing than the most common titanium alloys used by industry. Now the entrepreneur is working with researchers at Ohio State University (OSU) to better understand the science behind ... »

Research led to faster charging batteries capable to retain capacity

battery-braun-paul

A group of researchers from University of Illinois developed a three-dimensional nanostructure for battery cathodes that allows dramatically faster charging and discharging without sacrificing energy storage capacity. Aside from quick-charge consumer electronics, batteries that can store a lot of energy, release it fast and recharge quickly are desirable for electric vehicles, medical devices, lasers and ... »

Plasmonics with coated nanodomes for thin and affordable solar cells

stanford-plasmonics-imprints

A multidisciplinary team of Stanford engineers led by Mike McGehee, Yi Cui and Mark Brongersma, and joined by Michael Graetzel at the École Polytechnique Fédérale de Lausanne (EPFL), is developing a new type of thin solar cell that could offer a new direction for the field. They succeeded in harnessing plasmonics – trapping light within ... »

MIT researchers on a path to revive solar heat harvesting

fulvalene-diruthenium-molecule

Researchers explored the thermo-chemical approach to capture solar energy since the 1970s, but nobody could find a chemical that could reliably and reversibly switch between two states, absorbing sunlight to go into one state and then releasing heat when it reverted to the first state. Such a compound was discovered in 1996, but it included ... »

Photon Enhanced Thermionic Emission process boosts efficiency of solar panels

new-solar-testing-from-stanford-university

Stanford engineers have found out how to simultaneously use the light and heat of the sun to generate electricity in a way that could make solar power production more than twice as efficient as existing methods and potentially cheap enough to compete with oil. Unlike photovoltaic technology currently used in solar panels (which become less ... »
