A glimpse inside a graphene sandwich

 Nanotechnology News
 27 April 2022
Since the first successful fabrication of a two-dimensional structure of carbon atoms about 20 years ago, graphene has fascinated scientists. A few years ago, researchers discovered that two layers of graphene, slightly twisted against each other, can conduct electric current without loss. In recent...

Researchers develop a paper-thin loudspeaker

 Nanotechnology News
 26 April 2022
Researchers created an ultrathin loudspeaker that can turn any rigid surface into a high-quality, active audio source. The fabrication process can enable the thin-film devices to be produced at scale. ...

Measuring the 'wettability' of graphene and other 2D materials

 Nanotechnology News
 26 April 2022
Wettability of a material is the ability of a liquid to maintain contact with a solid surface, and it is proportional to hydrophilicity and inversely proportional to hydrophobicity. It is one of the most important properties of a solid, and understanding the wettability of different substrates is...

An easily reversed hydrogel male contraceptive

 Nanotechnology News
 26 April 2022
A team of researchers working at China's Fourth Hospital of Harbin Medical University has developed a new kind of male contraceptive that is easily reversed. In their paper published in the journal ACS Nano, the group describes their approach, the elements that went into making their contraceptive...

Learning chemical networks give life a chiral twist

 Nanotechnology News
 26 April 2022
A study shows that the preference of biological molecules for left or right-handedness -- a hallmark of living matter -- could emerge spontaneously as prebiotic chemical networks adapt to optimize energy harvesting. The proposed mechanism of symmetry breaking is general and can apply to other...
