How metal atoms can arrange themselves on an insulator

In order to produce tiny electronic memories or sensors in the future, it is essential to be able to arrange individual metal atoms on an insulating layer. Scientists at Bielefeld University's Faculty of Chemistry have now ...

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 ...

Soft support can make unexpectedly stable glass

Glasses are ubiquitous materials found in building materials, beverage containers, soft electronics, and mobile phone screens. The creation of naturally dense and rigid glass occurs through a process known as aging. It involves ...

Cherry picking molecules based on their Pi electrons

Specialized windshield glass, everyday plastic water bottles, and countless other products are based on ethylene, a simple two-carbon molecule, which requires an energy-intense separation process to pluck the desired chemical ...

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.

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.
