Application
Sputtering is a process whereby atoms are ejected from a solid target material due to bombardment of the target by energetic particles. The extreme miniaturization of components in the semiconductor and electronics industry requires high purity sputtering targets for thin film deposition.

Nanocomposite Coatings with Tunable Properties Prepared by Atomic Layer Deposition
Spintronics offer breakthroughs over conventional memory/logic devices with lower power, leakage, saturation, and complexity.
The properties of many devices are limited by the intrinsic properties of the materials that compose them.

Chemico-biological interactions, 196(3), 87-88 (2011-12-21)
There is emerging evidence that tungsten has toxic health effects. We summarize the recent tungsten toxicity research in this short review. Tungsten is widely used in many commercial and military applications because it has the second highest melting temperature of

Tungsten is a widely used transition metal that has not been thoroughly investigated with regards to its ecotoxicological effects. Tungsten anions polymerize in environmental systems as well as under physiological conditions in living organisms. These polymerization/condensation reactions result in the
Jan R Andreesen et al.
Annals of the New York Academy of Sciences, 1125, 215-229 (2007-12-22)
The history and changing function of tungsten as the heaviest element in biological systems is given. It starts from an inhibitory element/anion, especially for the iron molybdenum-cofactor (FeMoCo)-containing enzyme nitrogenase involved in dinitrogen fixation, as well as for the many
