The perfect atomic-scale sieve

Graphene is perfectly selective to protons and blocks even smallest ions like chlorine, University of Manchester research shows. This result will be important for the development of graphene-based membranes for applications ...

Developing a model critical in creating better devices

Water is everywhere. Understanding how it behaves at an intersection with another material and how it affects the performance of that material is helpful when trying to develop better products and devices. An undergraduate ...

Modified 'white graphene' for eco-friendly energy

Scientists from Tomsk Polytechnic University (TPU), together with colleagues from the United States and Germany, have found a way to obtain inexpensive catalysts from hexagonal boron nitride or "white graphene." The technology ...

How jackdaws remember what they did where and when

Corvids are capable of cognitive feats that almost resemble those of humans. Neuroscientists at Ruhr-Universität Bochum (RUB) intend to find out how their brain manages to fulfill such complex tasks – although its structure ...
