2 · Tungsten, or wolfram, is a chemical element with syol W and atomic nuer 74. The name tungsten comes from the former Swedish name for the tungstate mineral scheelite, tung sten or "heavy stone". Tungsten is a rare metal found naturally on Earth almost exclusively coined with other elements in chemical compounds rather than alone
Porous silicon (PSi) was doped by Er using electromigration or diffusion from a solution and converted to Er-doped silicon-rich silicon oxide (SRSO:Er) by partial thermal oxidation at 900-950C. The room temperature photoluminescence (PL) at 1.5 m is intense and narrow (15 meV) and decreases by less than 50% from 12 K to 300 K.

2019-4-23 · Cobalt is a chemical element with syol Co and atomic nuer 27. Like nickel, cobalt is found in the Earth''s crust only in chemically coined form, save for small deposits found in alloys of natural meteoric iron. The free element, produced by reductive smelting, is a hard, lustrous, silver-gray metal. Cobalt-based blue pigments (cobalt blue
2019-4-12 · To manufacture Reaction Bonded Silicon Carbide (RBSC), Silicon is infiltrated into a pre-formed silicon carbide/carbon powder green body which is then fired. This gives rise to around 10% free silicon, which fills the pores. The resulting microstructure has low porosity and a very fine grain.
The non-oxide ceramic silicon carbide (SiSiC or SSiC) is a ceramic material that is as hard as diamond and features many other important characteristics. The lightest and hardest ceramic material CeramTec offers is available as SSiC (sintered silicon carbide) and SiSiC (silicon infiltrated silicon carbide).
How to effectively improve the thermal conductivity of polymer materials approaching to that of diamond ? carbides and diamond exhibit heat conductivites ranging form a few hunderd to some

The basis for this device architecture is a silicon merane structure with micropores. In 1 M NaOH, a transport overpotential of 10 mV at 10 mA/cm 2 was achieved while still 97 % of the surface area consists of silicon, which can be used for light absorption. Even if 99.7 % is used for light absorption, this overpotential is still only 100 mV.

The whiskers produced have a diameter of approximately 1 μm and a length of 10–30 μm; they are straight and have a smooth surface.. The VLS method has also been used to produce TiN whiskers (Nixdorf and Rawlins, 1989; Nygren et al., 1995).The process for preparing TiN whiskers is similar to that described above for the synthesis of TiC whiskers except that the carbothermal reduction is
A simple technique of using silica nano particles as the masking layer in the Au assisted chemical etching process has been proposed for fabriion of silicon micro-nanopillars. A reduced reflection of ~2% over a spectral range of 300-1100 nm is obtained by the micro-nanopillars over silicon substrate.
