Roles of gas and solid components in the direct nitridation of silicon

Creator:

Pavarajarn, Varong

Abstract:

The factors influencing the direct nitridation of silicon, including the effects of the native oxide layer covering the surface of silicon, the effects of hydrogen contained in the nitridation gas and the catalytic effects of metals added to the raw material silicon, were investigated, using a tubular flow reactor and...

Feasibility study for the use of a fuel cell to process landfill gas at Coffin Butte Landfill : hydrogen sulfide (H2S) detection and removal

Creator:

Tuinstra, Hannah May

Abstract:

Pacific Northwest Generating Cooperative (PNGC) operates the Landfill Gas to Energy Facility at Coffin Butte Landfill in Corvallis, OR. At this facility, three internal combustion engines use the landfill gas (predominantly methane and carbon dioxide) as fuel to turn generators that produce enough electricity to power 1,800 average sized homes....

Electrochemical modeling of cathodic protection systems applied to reinforced concrete structures

Creator:

Muehlenkamp, Erik B.

Abstract:

A numerical model for the cathodic protection of steel in reinforced concrete is developed. Parameters are set to represent a three-dimensional section of a bridge beam exposed to the atmosphere and coated with a thermally sprayed zinc anode. Both diffusion of oxygen and conduction of charge within the concrete are...
