Does graphene cause or prevent the corrosion of copper? New study settles the debate

Scientists observe an unprecedented way in which graphene forms a hybrid layer that prevents copper corrosion.

Scientists propose new properties in hollow multishell structure

The Chinese puzzle ball is an ornate decorative artwork consisting of several concentric shells that move independently of each other. In the past decade, scientists provided a universal method for the fabrication of a conceptually similar micronanoscale structure, called the hollow multishell structure. New work proposes a novel concept of temporal-spatial ordering and dynamic smart behavior in these structures.

Ultrafast switching of an optical bit

Researchers have realized an all-optical bit that is temporarily written into a planar semiconductor nanostructure only using light and that can also be reconfigured only using optical techniques.

Catalyst deposition on fragile chips

Researchers have developed a new method of depositing catalyst particles to tiny electrodes. It is inexpensive, simple and quick to perform.
