Electron conflict leads to 'bad traffic' on way to superconductivity

Rice University physicists on the hunt for the origins of high-temperature superconductivity have published new findings this week about a seemingly contradictory state in which a material simultaneously exhibits the conflicting characteristics of both a metallic conductor and an insulator.

Tracing photochemical reactions

When light hits organic molecules, it triggers processes that are of considerable interest to scientists. But the individual steps of the reaction are very hard to identify. A study group at the University of Würzburg has now accomplished this task - with a sophisticated approach.

A fingerprint of exhaled breath

Researchers could show that exhaled human breath contains a characteristic molecular 'fingerprint'. The scientists want to use this finding to diagnose diseases based on the chemical analysis of patient's exhaled breath, using highly sensitive and precise instrumental methods.

Scientists use cloud of atoms as optical memory device

Talk about storing data in the cloud. Scientists at the Joint Quantum Institute (JQI) of the National Institute of Standards and Technology (NIST) and the University of Maryland have taken this to a whole new level by demonstrating that they can store visual images within quite an ethereal memory device - a thin vapor of rubidium atoms. The effort may prove helpful in creating memory for quantum computers.

Electron microscopy uncovers 'dancing' silicon atoms in graphene

Scientists documented the atoms' unique behavior by first trapping groups of silicon atoms, known as clusters, in a single-atom-thick sheet of carbon called graphene. The silicon clusters, composed of six atoms, were pinned in place by pores in the graphene sheet, allowing the team to directly image the material with a scanning transmission electron microscope.
