Building better electron sources with graphene

Photocathodes that produce electron beams for electron microscopes and advanced accelerators can be refreshed and rebuilt repeatedly without opening the devices that rely on them, provided the electron emitting materials ...

Researchers building a harder diamond, called pentadiamonds

Researchers at the University of Tsukuba used computer calculations to design a new carbon-based material even harder than diamond. This structure, dubbed "pentadiamond" by its creators, may be useful for replacing current ...

Molecular simulations show how drugs block key receptors

Many pharmaceuticals work by targeting what are known as 'G-protein-coupled receptors.' In a new study, scientists from Uppsala University describe how they have been able to predict how special molecules that can be used ...

Exploring mass dependence in electron-hole clusters

In solid materials, when an electron changes position without another to fill its place, a positively charged 'hole' can appear which is attracted to the original electron. In more complex situations, the process can even ...

Physicists study mirror nuclei for precision theory test

It's not often in nuclear physics that you can clearly get both sides of the story, but a recent experiment allowed researchers to do just that. They compared very similar nuclei to each other to get a clearer view of how ...
