Application

Tungsten (W) wire can be used for a variety of applications such as:
  • fabrication of tungsten tips which can be used as field emitters, nanoprobes and scanning tunneling microscope (STM) probes.
  • increase of the band gap of amorphous silicon germanium alloy.
  • formation of tungsten fibers for potential usage in the lighting industry.

Geometrical confinement effect in exfoliated sheets of layered materials leads to significant evolution of energy dispersion in mono- to few-layer thickness regime. Molybdenum disulfide (MoS(2)) was recently found to exhibit indirect-to-direct gap transition when the thickness is reduced to a...

Hyperlipidemia enhances xanthine oxidase (XO) activity. XO is an important source of reactive oxygen species (ROS). Since ROS are thought to promote atherosclerosis, we hypothesized that XO is involved in the development of atherosclerosis. ApoE(-/-) mice were fed a Western-type...
