Brain process takes paper shape

A paper-based device that mimics the electrochemical signalling in the human brain has been created by a group of researchers from China.

Waste that is brimming with energy

Together with the Italian GARBO corporation, the University of Greenwich, United Kingdom, and the University of Padua, Italy, as well as the midsized company EAAT from Chemnitz, Germany, the HZDR researchers are working on ...

Guinness World Record for discovery of the thinnest glass

It is only a couple of molecules thick, and could not be thinner: the sheet of glass that scientists at the University of Ulm and Cornell University have discovered by accident. This discovery has now been acknowledged as ...

Controlling friction by tuning van der Waals forces

For a car to accelerate there has to be friction between the tire and the surface of the road. The amount of friction generated depends on numerous factors, including the minute intermolecular forces acting between the two ...

Stirred, not shaken: Nanoscale magnetic stir bars

Anyone who has ever worked in a laboratory has seen them: magnetic stirrers that rotate magnetic stir bars in liquids to mix them. The stir bars come in many different forms—now including nanometer-sized. In the journal ...

Antioxidant with a long shelf life

(Phys.org) —Scientists from ETH Zurich have developed a nanomaterial that protects other molecules from oxidation. Unlike many such active substances in the past, the ETH-Zurich researchers' antioxidant has a long shelf ...

Catalyst keeps fruit fresh longer

(Phys.org) —Ripening fruit, vegetables, and flowers release ethylene, which works as a plant hormone. Ethylene accelerates ripening, so other unripened fruit also begins to ripen—fruit and vegetables quickly spoil and ...

X-rays reveal coexisting structures in glass

The craft of glassmaking extends way back in time. It was over five-thousand years ago when mankind learned how to make glass. Even prior to this discovery, humans had been using naturally occurring glass for tool making. ...
