Microwave processing and conventional furnace heating of dried sorghum leaves at temperatures in excess of 1400 °C in either vacuum or inert atmosphere produced nanoscale particles and nanorods of silicon carbide (SiC). This simple and fast method o

A simple method is presented for the analysis and design of gyrotron output couplers based on a Vlasov-type launcher and a single focusing mirror. It is shown that a quasi-analytical solution to the Kirchhoff diffraction integral can be implemented t

Mg-Ti alloys are attractive for structural applications because of low density and improved corrosion resistance by selective oxidation including hydrogen storage and switchable mirror applications. Titanium has a melting point (1670°C) that greatly

The emerging reduction technologies for titanium from ore produce powder instead of sponge. Conventional methods for sintering and melting of titanium powder are costly, as they are energy intensive and require high vacuum, 10-6 Torr or better, since

We present results on microwave, millimeter-wave, and millimeter-wave-driven plasma-assisted processing of materials. The research is primarily based on two systems- a 2.45 GHz, 6 kW S-band system and an 83 GHz, 15 kW gyrotron-based quasi-optical sys
