Expert Reviews

Jules L. Routbort, (Argonne National Laboratory, Argonne, USA)

Metallic tungsten has well-known chemical, physical, electrical, and mechanical properties that make it very useful for various applications: electron sources for field electron source application, protective coatings resistant to corrosion or atomic diffusion at high temperatures, interconnection lines, gate electrodes for integrated circuits, and diffusion barriers in integrated circuits with blanket or selective deposited film

Tungsten Nanowires: Due to its high stability of Tungsten, this material is used in various applications in engineering. The trend of miniaturization of devices increases the demands for the selected materials to consider size effects of their properties. Most of the mechanical phenomena are well-known on a macroscopic scale, however, they are hard to determine on a nanoscopic scale. There is a variety of theoretical predictions of hardness and Young’s modulus; mainly for carbon nanotubes, but only a few for nanowires (e.g., Au) which could not be confirmed experimentally up to date.

Tungsten Nanowires: Tungsten is a brittle refractory metal that crystallizes in body-centered cubic form. It has high tensile strength and good creep resistance. Due to its high stability, tungsten or tungsten oxide nanowires are promising candidates for a vast range of applications including, smart coatings, lithium-ion batteries cataly, electrochromatic materials, and nanostructured sensors

Dr. Myron Rubenstein, Ph.D, (Polytechnic University of Turin, Italy)

Tungsten Nanowires: Nanowires are unique for sensing applications as they exhibit high sensitivity, long-term stability, and large surface to volume ratios. For sensing applications, tungsten or tungsten oxide nanowires, are known to have a high sensitivity for detecting gasses such as ammonia, nitrogen dioxide, hydrogen sulfide, hydrogen, pH, and etc. at low parts per million and even as low as parts per billion levels.

Dr. Ms. Guixin (Susan), Ph.D, (Switzerland-Institute for Inorganic Chemistry, Zurich, Switzerland)

Tungsten Nanowires: One-dimensional nanowires are very attractive for high integrated nanoelectronics as well as nanomachine applications, showing low dimensional quantum physics, and thus they have been intensively studied by various synthesis method. In particular, metallic nanowire say as tungsten nanowire can be offer the possibility for both the first level nanogate and the second level nano-ohmic contact and interconnection for all nanocircuits or nanodevices.
