Catalytic and Non-catalytic Conversion of Methane to C2 Hydrocarbons in a Low Temperature Plasma

The direct conversion of methane to C2 hydrocarbons, in a quartz tube reactor enforced by a DC corona discharge, was investigated at atmospheric pressure. The process was carried out in the presence of metal oxide catalysts of Mn/W/SiO2, Mn/W/SiO2 (tetraethyl orthosilicate, TEOS), and Mn/W/CNT (supported on carbon nanotubes). The total yield to C2 hydrocarbons in the presence of metal oxide cat...

Impact of low-temperature plasmas on Deinococcus radiodurans and biomolecules.

The effects of cold plasma on Deinococcus radiodurans, plasmid DNA, and model proteins were assessed using microbiological, spectrometric, and biochemical techniques. In low power O(2) plasma (approximately 25 W, approximately 45 mTorr, 90 min), D. radiodurans, a radiation-resistant bacterium, showed a 99.999% reduction in bioburden. In higher power O(2) plasma (100 W and 500 mTorr), the reduct...

Collision Processes in Low-Temperature Hydrogen Plasmas

Collision processes among the constituents of low-temperature hydrogen plasmas (e,H,H,H,H2,H + 2 ,H + 3 ) play a key role in technical plasma applications as well as in the boundary regions of magnetically confined fusion plasmas. In this work a review of the current knowledge on their cross sections is presented. Collision processes of electronically and vibrationally excited species are also ...

Application of Low-Temperature Plasma Processes for Biomaterials

Proceedings of the Symposium on Low Temperature Electronics and High Temperature Superconouctivity

This paper discusses the electrical properties of the complementary heterojunction field-effect transistor (CHFET) at 4 K, induding the gate leakage current, the subthreshold transconductance, and the input-referred noise voltage. The CHFET is a GaAs-based transistor analogous in structure and operation to silicon CMOS, and is being explored for possible application in readout electronics opera...
