Dynamics of High- and Low -Pressure Plasma Remediation
The use of DBDs as excimer ultraviolet (UV) lighting sources was also studied. The mixture Xe/Cl2 ≈ 99/1 was found to be an optimum gas mixture for the generation of the XeCl*. Higher applied voltage improves both the intensity and efficiency of UV photon generations. The strong attachment at high …

Solid oxide fuel cell electrolytes produced via very low pressure suspension plasma spray and electrophoretic deposition
… as hydrogen, into electrical energy. Both very low pressure plasma spray and electrophoretic deposition allow working with high melting temperature SOFC suspension based feedstock on complex surfaces, such as in non-planar SOFC designs. Dense, thin electrolytes of ideal composition for SOFCs can …
