Numerical modelling of low temperature plasma
… of basic physical processes occurring in low temperature plasmas. This is achieved by applying both analytic and numerical models. Low temperature plasmas are found in both technological and astrophysical contexts. Three different situations are investigated: an instability in …

Zircon behaviour in low temperature environments
… In these rocks, zircon readily responds to low temperature events due to radiation damage in its crystal lattice while crystalline zircon remains unmodified. Zircon that alters as a result of metamictization has a low BSE intensity (dark BSE zircon) and electron microprobe measurements show …

Universal properties of low-temperature glass
… from that of crystalline counterparts at low temperatures, regardless of their microscopic nature. Tunneling-two-level-system model (TTLS model) successfully explained several universalities below 1K, but it cannot explain the other glass low-temperature universal properties. Based on …

Microprocessor Controlled Low Temperature Grain Drying
… capable of optimizing the drying process in a low temperature corn drying bin by controlling the drying fan operation. A procedure was developed to predict the moisture profile in a drying bin based on the measured temperature profile. This procedure was incorporated into a controlling …

Recombination in low temperature helium plasmas
A study was made of the afterglows of plasmas produced in pure helium gas at atomic densities ~lo18 - lo19/cc . Qualitative observations were made at a gas temperature of 4.20K while most quantitative results were obtained at a gas temperature of 77 o K at a pressure of 9.5 Torr in a region of free …

Low Temperature Drying of Ultrafine Coal
A new dewatering technology, called low temperature drying, has been developed to remove water from ultrafine (minus 325 mesh) coal particles. The process subjects partially dewatered solids to intense mechanical shearing in the presence of unsaturated air. Theoretical analysis of the thermodynamic …

Low temperature bulk modulus of solid argon
… measured as a function of pressure at constant temperature using a high precision back-reflection X-ray camera. Low temperature measurements, using helium as the pressure transmitting fluid, are reported which cover the pressure range of 10 to 300 bar. These measurements, which are the first …

Low-temperature thermal expansion of amorphous solids
"For most amorphous materials at temperatures below ~ 1 K, the magnitudes and temperature dependences of specific heat, thermal conductivity and ultrasonic dispersion are qualitatively similar, independent of chemical composition. It has been suggested that thermal expansion also exhibits this …

Optimal MOSFET design for low temperature operation
… smaller devices faces significant challenges. Lowering the operating temperature can help achieve the desired increases in performance as device size scales. Lowering the temperature reduces the off-state leakage of a MOSFET removing constraints on reducing the threshold voltage. In addition, …
