Self-assembling nanomaterial a pathway to more efficient, affordable harnessing of solar power

Singlet fission reaction creates more and extends the life of electronic charges

28-Jan-2019

Solar rays are a plentiful, clean source of energy that is becoming increasingly important as the world works to shift away from power sources that contribute to global warming. But current methods of harvesting solar charges are expensive and inefficient--with a theoretical efficiency limit of ...

Combining 3D printing and metals science leads to stronger, crystal-inspired materials

24-Jan-2019

Imperial materials scientists have created new artificial materials which combine our knowledge of metals with 3D printing. The findings could speed up the use of 3D printed materials in everything from construction and vehicles to medical devices. 3D printing is often used to produce engineering ...

A transparent flexible material of silk and nanotubes

Nanotube interactions with silk fibroins - key to flexible, degradable electronics

02-Nov-2018

The silk fibers produced by Bombyx mori, the domestic silkworm, has been prized for millennia as a strong yet lightweight and luxurious material. Although synthetic polymers like nylon and polyester are less costly, they do not compare to silk's natural qualities and mechanical properties. And ...

Nanoparticles' defects can be useful

27-Jun-2018

According to Yulia Kuznetsova, defects in nanoparticles play a very serious role in the formation of their real structure and physical properties. Therefore, having learned to create the necessary defects in the required quantities, we can control characteristics of such materials. In other ...

A path to sustainable and biodegradable polyesters

04-Jun-2018

There's a good chance you've touched something made out of the polyolefin polymer today. It's often used in polyethylene products like plastic bags or polypropylene products like diapers. As useful as polyolefins are in society, they continue to multiply as trash in the environment. Scientists ...

Squid skin could be the solution to camouflage material

01-Mar-2018

Cephalopods -- which include octopuses, squid, and cuttlefish -- are masters of disguise. They can camouflage to precisely match their surroundings in a matter of seconds, and no scientist has quite been able to replicate the spectacle. But new research by Leila Deravi, assistant professor of ...

Charge order and electron localization in a molecule-based solid

23-Jan-2018

Charge ordering in cationic mixed-valence compounds is of crucial importance for materials science. The prototypic example for a transition from a charge-disordered to a charge-ordered state has been magnetite, Fe3O4, where Evert Verwey observed a sudden jump in resistivity near -150°C. In the ...

Harnessing the rattling motion of oxygen ions to convert T-rays to visible light

01-Dec-2017

Scientists have successfully visualized terahertz radiation, popularly known as T-rays, using a crystal called mayenite (Ca12Al14O33). Their method cleverly utilizes the rattling motion caused by the vibration of oxygen ions inside the cage-like structures of the crystal. In recent years, there ...

A material with promising properties

Successful synthesis of an important ferromagnetic semiconductor

23-Nov-2017

The Collaborative Research Centre CRC 1214 at the University of Konstanz has developed a method for synthesising Europium (II) oxide nanoparticles - a ferromagnetic semiconductor that is relevant for data storage and data transport Ferromagnetic semiconductors have attracted increasing attention ...

'Ion billiards' cue novel material synthesis method

21-Nov-2017

A team of Hokkaido University researchers has developed a novel material synthesis method called proton-driven ion introduction (PDII) which utilizes a phenomenon similar to "ion billiards." The new method could pave the way for creating numerous new materials, thus drastically advancing ...
