Researchers patent new electrolytes based on ionic liquids that prolong the life of solar cells and batteries

Researchers have discovered a new family of ionic liquids that produce electrolytes that improve the performance, stability and durability of electrochemical and electronic devices.

Nanomaterial to help reduce carbon dioxide emissions

Researchers have developed a new nanomaterial that could help reduce carbon dioxide emissions from coal-fired power stations.

Science Team Outlines Goals for NASA's 2020 Mars Rover

The rover NASA will send to Mars in 2020 should look for signs of past life, collect samples for possible future return to Earth, and demonstrate technology for future human exploration of the Red Planet, according to a report provided to the agency.

NASA Invites Media to View Orion Heat Shield Near Boston

NASA officials will visit Textron Defense Systems in Wilmington, Mass., Wednesday, July 17, to view progress being made on the heat shield for the agency's Orion spacecraft.

Researchers perform first direct measurement of Van der Waals force

(Phys.org) —Researchers working at the French National Center for Scientific Research have for the first time, directly measured the Van der Waals force between two atoms. In their paper published in the journal Physical Review Letters, the team describes how they used lasers to hold two atoms steady and a third laser to measure the Van der Waals force between them.

Buckling up to turn: Marine microbes change swimming direction via a high-speed mechanical instability

Bacteria swim by rotating the helical, hairlike flagella that extend from their unicellular bodies. Some bacteria, including the Escherichia coli (E. coli) living in the human gut, have multiple flagella that rotate as a bundle to move the cell forward. These cells turn somewhat acrobatically by unbundling their flagella, causing the cell to tumble, reorient and strike out in another direction.

Scientists solve titanic puzzle of popular photocatalyst

A breakthrough in our understanding of the properties of titania (titanium dioxide) -- the basis of self-cleaning window technology -- has been made by scientists, uncovering a decades old misunderstanding that has clouded our knowledge of how mixed phase titania catalysts operate.

Researchers develop light transistor

TU Vienna has managed to turn the oscillation direction of beams of light – simply by applying an electrical current to a special material. This way, a transistor can be built that functions with light instead of electrical current.
