Engineers at the University of Maryland have created a thin battery, made of a few million carefully constructed "microbatteries" in a square inch. Each microbattery is shaped like a very tall, round room, providing much ...
From airplane wings to overhead powerlines to the giant blades of wind turbines, a buildup of ice can cause problems ranging from impaired performance all the way to catastrophic failure. But preventing that buildup usually ...
In a study published in Science this week, the researchers describe the dielectric properties of water that is only a few molecules thick. Such water was previously predicted to exhibit a reduced electric response but it ...
A precise, chemical-free method for etching nanoscale features on silicon wafers has been developed by a team from Penn State and Southwest Jiaotong University and Tsinghua University in China.
Searching for signs of ice on Mars is complex. To explore whether ice lurks beneath the surface of the Red Planet, ESA's Mars Express uses its radar to probe the interior.
A new method to make a low-cost, high-quality lens quickly using a 3D printer has promising potential to create optical imaging lenses, customized contact lenses for correcting distorted vision, or to even turn iPhones into ...
A team of researchers from the U.S., China and Canada has found evidence in diamonds of free-flowing water in the boundary between Earth's upper and lower mantle. In their paper published in the journal Science, the group ...
Graphene floating on water does not repel water, as many researchers believe, but rather attracts it. This has been demonstrated by chemists Liubov Belyaeva and Pauline van Deursen and their supervisor Grégory F. Schneider. ...
Scientists at the U.S. Department of Energy's Ames Laboratory have discovered a new process to sheathe metal under a single layer of graphite which may lead to new and better-controlled properties for these types of materials.
The outermost layer of ice behaves like liquid water, even at a temperature of –30°C. Physicists at AMOLF have irrefutably demonstrated this using a modern surface-sensitive measuring technique. At lower temperatures, ...
