How quantum dots can 'talk' to each other

So-called quantum dots are a new class of materials with many applications. Quantum dots are realized by tiny semiconductor crystals with dimensions in the nanometre range. The optical and electrical properties can be controlled ...

Faster fusion reactor calculations thanks to machine learning

Fusion reactor technologies are well-positioned to contribute to our future power needs in a safe and sustainable manner. Numerical models can provide researchers with information on the behavior of the fusion plasma, as ...

Paving the way for tunable graphene plasmonic THz amplifiers

Tohoku University Professor Taiichi Otsuji has led a team of international researchers in successfully demonstrating a room-temperature coherent amplification of terahertz (THz) radiation in graphene, electrically driven ...

Bluetooth-enabled device detects fermentation process over days

Electrochemical reactions that occur in processes like ethanolic fermentation include the transformation of sugars into alcohol and carbon dioxide. Similar processes occur when the human body breaks down food, drugs or other ...

Self-healing electroluminescent (EL) devices

In a recent study, materials scientists Guojin Liang and his coworkers at the Department of Materials Science and Engineering, City University of Hong Kong, have developed a self-healing, electroluminescent (EL) device that ...
