Surfaces help quantum switches

The quantum dynamics of hydrogen are central to many problems in nature, being strongly influenced by the environment in which a reaction takes place. In their contribution to PRL, members of the Lise Meitner Group at the ...

Molecular swarm rearranges surface structures atom by atom

The surface of metals plays a key role in many technologically relevant areas, such as catalysis, sensor technology and battery research. For example, the large-scale production of many chemical compounds takes place on metal ...

Why we should leave old oil rigs in the sea, and why we don't

Decommissioning the UK's offshore oil and gas infrastructure will cost the taxpayer £24 billion, according to estimates from HMRC. So why can't we leave man-made structures in the sea and thereby save the cost of removal ...

Giant nanomachine aids the immune system

Cells that are infected by a virus or carry a carcinogenic mutation, for example, produce proteins foreign to the body. Antigenic peptides resulting from the degradation of these exogenous proteins inside the cell are loaded ...

The mathematical magic of bending grids

An amazing construction method for curved structures was developed at TU Wien (Vienna): With a flick of the wrist, flat grids become a 3-D shape.
