The Solar Impulse 2 aircraft has ended its US portion of its bid to circle the globe using only solar power. “It’s absolutely incredible,” Swiss pilot Andre Borschberg said. “It’s a dream here.” The light, slow-moving aircraft later landed at New York’s Kennedy Airport, completing the 5h flight from Lehigh Valley Airport in Pennsylvania, 1 minute ahead of schedule at 3:59 am (0759 GMT).

It was the 14th leg of an east-west journey that began March 9, 2015 in Abu Dhabi, and has taken the aircraft across Asia and the Pacific to the US. From NY the Solar Impulse team will attempt to cross the Atlantic to Europe and on to the Middle East...

“Our research team has developed a simple and cost-effective fabrication technique to create solar absorbers that can harness a greater share of the solar spectrum, thus increasing their efficiencies, while also maintaining low emission levels,” said Masdar Institute’s Dr. TieJun Zhang, Assistant Professor of Mechanical and Materials Engineering.

Scientists design Energy-carrying Particles called ‘Topological Plexcitons’

Plexcitons travel for 20,000 nanometers, a length which is on the order of the width of human hair. Graphic by Joel Yuen-Zhou

Scientists at UC SD, MIT and HarvardU have engineered “topological plexcitons,” energy-carrying particles that could help make possible the design of new kinds of solar cells and miniaturized optical circuitry. Within the Lilliputian world of solid state physics, light and matter interact in strange ways, exchanging energy back and forth between them.

“When light and matter interact, they exchange energy,” explained Assistant/Prof. Joel Yuen-Zhou. “Energy can flow back and forth between light in a metal (so called plasmon) and light in a molecule (so called exciton)...

Magnetic Material could host wily Weyl fermions

An ORNL-led research team used neutrons (depicted as spheres) to determine the magnetic structure (seen as blue arrows) of an osmium-based material. X-rays (seen as purple waves) revealed the presence of a strong spin orbit effect (illustrated in red). Credit: ORNL/Jill Hemman

An elusive massless particle could exist in a magnetic crystal structure, revealed by neutron and X-ray research. The team studied a material containing the dense element osmium and documented 2 conditions required for the presence of Weyl fermions -predicted in 1929 and observed experimentally in 2015. Researchers are looking for other materials that could host them to harness their unique properties in spintronics and advanced computing applications such as quantum computers.

“Once you have a material that hosts th...
