Component of volcanic gas may have played a significant role in the origins of life on Earth
...H3 gases in a glass apparatus containing a pair of tungsten
electrodes. He subjected the chemicals to an electric discharge, intended to simulate conditions on the early Earth, and he collected and analyzed the molecules that formed--which included the amino acids alanine, glycine, and a few others. In the ye...
Diamonds are a doctor's best friend
...or drill bits and abrasive materials, non-clogging tungsten
carbide milling inserts for engineering applications, and more efficient, lower friction, automotive components that are more fuel efficient. DLC coatings are also biocompatible and unlike other types of coating don't trigger the coagulation of blood...
On the cutting edge: Carbon nanotube cutlery
...n nanotube between two electrochemically sharpened tungsten
needles. In the resulting prototype, the nanotube stretches between two ends of a tungsten
wire loop. The knife resembles a steel wire that cuts a block of cheese. To begin demonstrating the...
Scientists learning to create nanomaterials based on micro-algae patterns
...nique called microparticle bombardment. DNA-coated tungsten
particles are shot on the diatoms under high heliumpressure, thus enabling them to penetrate the strong diatom cell wall. The diatom incorporates the introduced DNA into its genome, and selection of the transfected cells is achieved using the antibio...
