Nothing but air - novel cellulose-silica gel nanocomposite aerogels

Delicate and translucent as a puff of air, yet mechanically stable, flexible, and possessing amazing heat-insulation properties - these are the properties of a new aerogel made of cellulose and silica gel. Researchers have introduced this novel material, which consists almost completely of air.

Graphene can also be used for distilling alcohol

A team led by Andre Geim shows that graphene-based membranes are impermeable to all gases and liquids (vacuum-tight). However, water evaporates through them as quickly as if the membranes were not there at all.

Berkeley Lab to develop novel materials for hydrogen storage

The biggest challenge with hydrogen-powered fuel cells lies in the storage of hydrogen: how to store enough of it, in a safe and cost-effective manner, to power a vehicle for 300 miles? Lawrence Berkeley National Laboratory (Berkeley Lab) is aiming to solve this problem by synthesizing novel materials with high hydrogen adsorption capacities.

Speed limit on the quantum highway

A quantum computer based on quantum particles instead of classical bits, can in principle outperform any classical computer. However, it still remains an open question, how fast and how efficient quantum computers really may be able to work. A critical limitation will be given by the velocity with which a quantum signal can spread within a processing unit. For the first time, a group of physicists has succeeded in observing such a process in a solid-state like system.

Scientists create first free-standing 3-D cloak

Researchers in the US have, for the first time, cloaked a three-dimensional object standing in free space, bringing the much-talked-about invisibility cloak one step closer to reality. Whilst previous studies have either been theoretical in nature or limited to the cloaking of two-dimensional objects, this study shows how ordinary objects can be cloaked in their natural environment in all directions and from all of an observer's positions.
