The essay, "What Has Government Done to Our Money?" was written by Rothbard as an objective historical account with a provocative title. In contrast, "The Case for a 100 Percent Gold Dollar" was an essay with an
Ultra-high-purity steam for oxidation and annealing Ultra-high-purity steam for oxidation and annealing Ultra-high-purity steam, also called clean steam, UHP steam or high purity water vapor, is used in a variety of industrial manufacturing processes that require oxidation or annealing. These processes include oxide layers grow on silicon wafers for the semiconductor industry and for passivation layers used to improve the light capture ability of crystalline photovoltaic cells. Several methods and technologies can be employed to generate ultra high purity steam, including pyrolysis, bubbling, direct liquid injection and purified steam generation. The level of purity, or the relative lack of contamination, affects the quality of the oxide
