1. Clear-fused quartz is the choice for cold-wall reactors, especially because of its transmittivity over the required light frequencies. 2. For hot-wall reactors, quartz still dominates, but there are some appliions for silicon carbide tubes; however, SiC use is less common for process tubes than for carriers.

Diffusion of Adhesion Layer Metals Controls …

The electrical results of these devices agree with the scenario that Ti or Cr can diffuse through the 15 nm bottom Pt electrode to react with the TiO 2 at the bottom interface during hot deposition of TiO 2 and form a locally reduced oxide, denoted TiO 2−x (i.e. an oxide characterized by significant oxygen vacancies). We propose this diffusion creates the seeds for subsequent growth of

Ultra-High-Temperature Ceramics (UHTC) materials based on refractory metal diborides (HfB2 or ZrB2) and containing optimum silicon carbide concentration (in either bulk or CMC form) have demonstrated the best performances to date. However, these alloys are still not thermal shock resistant enough for reliable use in a cyclic environment.

Multiple forms of mobility, manipulation and human-robot interaction offer great promise in exploring planetary bodies for science investigations and to support human missions. Enhancements and potentially new forms of robotic systems can be realized through advances in component technologies, such as actuation and structures (e.g. 3D printing).

US Patent for Methods and structures for metal

A typical integrated-circuit fabriion requires interconnecting millions of microscopic transistors and resistors with metal wires. Making the metal wires flush, or coplanar, with underlying insulation requires digging trenches in the insulation, and then filling the trenches with metal to form the wires. The invention provides a new “trench-less” or “self-planarizing” method of
