Unexpected speed-dependent friction with graphene

Dec 07, 2022 (Nanowerk News) Due to their low-friction properties, materials consisting of single atomic layers are of great interest for applications where the aim is to reduce friction — such as hard disks or moving components for satellites or space telescopes. One such example is graphene, which consists of...

Breakage-resistant conductive hydrogel extends service life of triboelectric nanogenerators

Dec 07, 2022 (Nanowerk News) Researchers led by Prof. CHEN Tao at the Ningbo Institute of Materials Technology and Engineering (NIMTE) of the Chinese Academy of Sciences (CAS), in cooperation with researchers at Ningbo University, have developed a novel breakage-resistant conductive hydrogel (BRC hydrogel) with excellent mechanical reliability, extending the service...

The perovskite solar cells tough enough to match mighty silicon

Dec 07, 2022 (Nanowerk News) Researchers at Oxford University and Exciton Science have demonstrated a new way to create stable perovskite solar cells, with fewer defects and the potential to finally rival silicon’s durability. By removing the solvent dimethyl-sulfoxide and introducing dimethylammonium chloride as a crystallisation agent, the researchers were...

A nano-based technology to fight osteoporosis

Dec 07, 2022 (Nanowerk News) University of Central Florida researchers have created unique technology for treating osteoporosis that uses nanobubbles to deliver treatment to targeted areas of a person’s body (Nanomedicine, "A novel ultrasound-mediated nanodroplet-based gene delivery system for osteoporosis treatment"). The new technology was developed by Mehdi Razavi, an...

Long-range information transport in antiferromagnets

Dec 07, 2022 (Nanowerk News) Smaller, faster, more powerful: The demands on microelectronic devices are high and are constantly increasing. However, if chips, processors and the like are based on electricity, there are limits to miniaturization. Physicists are therefore working on alternative ways of transporting information, such as about spin...
