Landfill gas (LFG) is a natural byproduct of the decomposition of organic material in landfills. LFG is composed of roughly 50 percent methane (the primary component of natural gas), 50 percent carbon dioxide (CO 2) and a small amount of non-methane organic compounds. Methane is a potent greenhouse gas at least 28 times …

Horizontal HVPE. This horizontal hydride vapor phase epitaxy system is simpler and more compact that its vertical counterpart. The samples are easily mounted on a molybdenum susceptor that is inductively heated as high as 1400° C. A venturi pump is used to reduce the pressure within the reactor to improve uniformity of the process gas flow.

Nitrogen is a non-flammable air gas that forms 78% of the earth's atmosphere. Valued for its inert properties in its gaseous form, nitrogen displaces air and therefore, reduces or eliminates the oxidation of materials. It is also used as an assist gas for laser cutting. Given the extremely low temperatures of its liquid state, nitrogen is an ...
