Decomposition Of Carbon Dioxide In A Capacitively Coupled Radio Frequency Discharge, Thao Hoang Dinh
Physics Theses & Dissertations
Decomposition of CO2 was studied in a capacitively coupled radio frequency discharge using Martian Simulant Gas mixture that contains 95% CO2. The discharge was operated at a gas pressure of 3 to 6 Torr and a discharge power density of less than 2.0 W/cm3. The main mechanism of the CO2 decomposition process is the electron impact dissociation and the rate of the process depends on the electron density, Ne, the concentration of CO2, and the reduced electric field, E/N. A self-consistent model was established to describe the CO …
Decomposition Dynamics In Restored And Naturally Recovering Atlantic White Cedar (Chamaecyparis Thyoides) Wetlands, Edward Ratcliffe Crawford
Decomposition Dynamics In Restored And Naturally Recovering Atlantic White Cedar (Chamaecyparis Thyoides) Wetlands, Edward Ratcliffe Crawford
Biological Sciences Theses & Dissertations
Restoration efforts and ecologically based management practices for Atlantic white cedar wetlands have recently focused on soil organic matter sequestration and aggradation as critical ecosystem functions in the maintenance of this imperiled community type. This work addresses how developmental stage, litter quality and environmental conditions influenced above ground leaf litter and below ground root decay in naturally regenerating and restored Atlantic white cedar wetlands. Using standard litterbags for leaf litter and a modified litterbag technique for roots, decay dynamics of naturally regenerating and restored Atlantic white cedar stands were measured to compare ecosystem development trends with restoration conditions. Effects on …
