[Materials] – A nanoscale lattice of palladium and yttrium makes for a superlative carbon-linking catalyst 23 février 2020

A group of materials scientists at Tokyo Institute of Technology has shown that a palladium-based intermetallic electride, Y3Pd2, can improve the efficiency of carbon-carbon cross-coupling reactions. Their findings point the way to a more sustainable world through catalysis.

[2D materials] – Stretched to the limit and sparkling on curved surfaces 23 février 2020

Two-dimensional (2D) materials could offer new building blocks for future technologies — but only if scientists can control growth and properties. Strain, caused by “stretching” or “bunching” the atomic structure as a crystal grows, is one way to control these properties.

[Photovoltaic] – If you want to catch more light, twist it 23 février 2020

A special class of materials known as “Weyl semimetals” have unusual physical properties. In these materials, researchers can separate electrons by their “handedness.” That’s whether the electrons’ magnetic moment is in the same direction as the electrons’ movement or the opposite direction.
This results in a host of unique phenomena that researchers can use to turn infrared light into electricity and develop very fast electronic circuits.

[2D Material] – No strain, no gain! breakthrough in 2D material that produces single photons 23 février 2020

Quantum information technologies need materials that can produce a regular stream of single particles of light (photons). Two-dimensional materials are made of single layers of coordinated atoms.
Recent research has shown that these 2D materials may have potential as light sources that emit light as single photons.
