Investigating nanopillars - Silicon brittle? Not this kind!
Silicon, the most important semiconductor material of all, is usually considered to be as brittle and breakable as window glass. On the nanometer scale, however, the substance exhibits very different properties, as Empa researchers have shown by creating minute silicon pillars.

New aluminum-water rocket propellant promising for future space missions
Researchers are developing a new type of rocket propellant made of a frozen mixture of water and "nanoscale aluminum" powder that is more environmentally friendly than conventional propellants and could be manufactured on the moon, Mars and other water-bearing bodies.

A splash of graphene improves battery materials
Researchers would like to develop lithium-ion batteries using titanium dioxide, an inexpensive material. But titanium dioxide on its own doesn't perform well enough to replace the expensive, rare-earth metals or fire-prone carbon-based materials used in today's lithium-ion batteries.

Cement’s basic molecular structure finally decoded
In the 2,000 or so years since the Roman Empire employed a naturally occurring form of cement to build a vast system of concrete aqueducts and other large edifices, researchers have analyzed the molecular structure of natural materials and created entirely new building materials such as steel, which has a well-documented crystalline structure at the atomic scale.

Superconductivity 'fingerprint' found at higher temperatures
New measurements at Cornell have shown that "high-temperature" superconductors may have the potential to go even higher, offering the possibility of creating room-temperature superconductors, or at least superconductors that will work with conventional refrigeration.

New eco-friendly self-cleaning material tough on stains, light on effort
Cleaning oily smears from kitchen countertops, mirrors, garage floors, and other surfaces with plain water — rather than strong detergents or smelly solvents — may seem like pure fantasy. But scientists in Indiana today describe what they believe to be a simple and effective state-of-the-art oil stain remover.

Secrets of the sandcastle worm could yield a powerful medical adhesive
Scientists have copied the natural glue secreted by a tiny sea creature called the sandcastle worm in an effort to develop a long-sought medical adhesive needed to repair bones shattered in battlefield injuries, car crashes and other accidents. They reported on the adhesive here today at the 238th National Meeting of the American Chemical Society (ACS).
