Plasma

A new, extremely efficient source of terahertz radiation has been developed at TU Wien (Vienna): Lasers turn air into plasma, thereby producing terahertz rays for many possible applications. Terahertz radiation is used for security checks at airports, for medical examinations and also for quality ch more

Using a trick modelled on the Trojan Horse, a novel electron source can generate extremely brilliant particle beams. The new method uses plasma acceleration technology and promises 100 to 10,000 times more tightly focused electron beams than conventional accelerators can currently deliver. An intern more

A plasma tears through the water within a few nanoseconds. It may possibly regenerate catalytic surfaces at the push of a button. Electrochemical cells help recycle CO2. However, the catalytic surfaces get worn down in the process. Researchers at the Collaborative Research Centre 1316 “Transient atm more

In this paper, we explore a variety of aqueous digestion techniques for the determination of gold, in a wide variety of mineral matrices. These include feldspar, basalt, pyrites, and other gold-containing minerals. The acid-based digestion methods compete effectively with fire assay to deliver accur more
