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

[Optic] – Lasers etch a ‘perfect’ solar energy absorber 23 February 2020

The University of Rochester research lab that recently used lasers to create unsinkable metallic structures has now demonstrated how the same technology could be used to create highly efficient solar power generators.

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

[Nanotechnology] – Bending diamond at the nanoscale 23 February 2020

Diamond is prized by scientists and jewellers alike, largely for a range of extraordinary properties including exceptional hardness. Now a team of Australian scientists has discovered diamond can be bent and deformed, at the nanoscale at least.

[Nano-Medecine] – Researchers propose new concept for DNA-based nanorobot to fight cancer 23 February 2020

A group of researchers from ITMO University has come up with the concept of a new drug against cancer: a nanorobot made of DNA fragments, which can potentially be used not only to destroy cancer cells but also to locate them in the body.
