Not all ions in tokamaks go with the flow

For the first time, scientists are measuring the rotation of the main (deuterium) plasma in the edge region of a fusion device. New spectroscopic measurements combined with state-of-the-art spectroscopic simulation made this ...

High performance graphene-based catalysts

NUS scientists have developed design guidelines that increase the catalytic effectiveness of graphene-based solid state catalysts for potential industry applications.

Individual impurity atoms detectable in graphene

A team including physicists from the University of Basel has succeeded in using atomic force microscopy to obtain clear images of individual impurity atoms in graphene ribbons. Thanks to the forces measured in the graphene's ...

How do impurities move in tungsten?

One part of the vacuum vessel (the plasma facing material) of the fusion experimental device and future fusion reactor comes into contact with plasma. When the plasma ions enter into the material, those particles become a ...

Controlling interactions between distant qubits

A big part of the burgeoning science of quantum computation is reliably storing and processing information in the form of quantum bits, or qubits. One of the obstacles to this goal is the difficulty of preserving the fragile ...
