Graphene changes elastic properties depending on applied force

Apr 18 2018 - 00:04
A research group, including scientists from Landau Institute for Theoretical Physics (ITF), described a universal feature, in which many unique graphene properties are hidden. The study showed that abnormal graphene behavior can be fully characterised by Poisson ratio, which determines material capability to shrink or extend in transverse dimension. Moreover, the scientists found key factors that can influence this feature. The results are published in Physical Review B.

Peptide induces chirality evolution in a single gold nanoparticle

Apr 18 2018 - 00:04
Seoul National University has created a synthesis method to make optically active and chiral gold nanoparticles using amino acids and peptides for the first time. Many chemicals significant to life have mirror-imaged twins and such characteristics are conventionally called as chirality. This study describes how the chirality, typically observed in organic molecules, can be extended to three-dimensional metallic nanostructures. The research will be published in Nature and featured in its cover.

Researchers design 'soft' robots that can move on their own

Apr 18 2018 - 00:04
If Star Wars' R2-D2 is your idea of a robot, think again. Researchers led by a University of Houston engineer have reported a new class of soft robot, composed of ultrathin sensing, actuating electronics and temperature-sensitive artificial muscle that can adapt to the environment and crawl, similar to the movement of an inchworm or caterpillar.

Iron Age breeding practices likely influenced lack of stallion lineages in modern horses

Apr 18 2018 - 00:04
Selective breeding just before and during the Iron Age nearly 3,000 years ago is likely the reason for the lack of variability in modern domestic horses' paternally inherited DNA, a trait unique among livestock animals.

Study reveals new Antarctic process contributing to sea level rise and climate change

Apr 18 2018 - 00:04
A new study has revealed a previously undocumented process where melting glacial ice sheets change the ocean in a way that further accelerates the rate of ice melt and sea level rise.Led by IMAS PhD student Alessandro Silvano and published in the journal Science Advances, the research found that glacial meltwater makes the ocean's surface layer less salty and more buoyant, preventing deep mixing in winter and allowing warm water at depth to retain its heat and further melt glaciers from below.
