Future bright for mini synchrotrons

Colliding a stream of electrons with laser light near an array of tiny silver structures could be the recipe for a new X-ray source that could revolutionize medical imaging and security scanning.

Real-time imaging of chemical processes

National University of Singapore scientists observe the real-time formation of hollow structures in the galvanic replacement (GR) reaction between silver and gold with nanometre resolution, gaining insights on the mechanisms ...

Imprinting nano-patterns in metals

Materials scientists at the TU Darmstadt are imprinting nano-patterns in metals, a technology that could give metallic surfaces permanent functionality, like a lotus effect or reduced frictional properties.

Soft decoupling of organic molecules on metal

An international team has discovered an elegant way to decouple organic nanosheets grown on metal surfaces. After iodine intercalation, measurements at the synchrotron source BESSY II of Helmholtz-Zentrum Berlin showed that ...

Successful boron-doping of graphene nanoribbon

Physicists at the University of Basel succeed in synthesizing boron-doped graphene nanoribbons and characterizing their structural, electronic and chemical properties. The modified material could potentially be used as a ...

Hydrocarbon photocatalysts get in shape and go for gold

A combination of semiconductor catalysts, optimum catalyst shape, gold-copper co-catalyst alloy nanoparticles and hydrous hydrazine reducing agent enables an increase of hydrocarbon generation from CO2 by a factor of ten.
