1 Introduction The Great Salt Lake(GSL)is the defining hydrological feature of the Great Basin,North America’s largest desert--and it is the largest waterbody in the western USA.Despite the early(Eardley,1938)recognition of'bioherms,'algal layers,and mats covering hundreds of square km of lake area,these features have…
A strong influence of nitrogen gas on the content of surface hydroxyl groups of TiO2 films by atomic layer deposition(ALD) was investigated by X-ray photoelectron spectroscopy(XPS), contact angle measuring system, and UV–Vis spectrophotometer. XPS spectra of O 1s indicate that the content of surface hydroxyl groups is…
Multi-arc ion plating technique was adopted to prepare TiN film on the surface of LY12 aluminum alloy.The structure of as-prepared TiN film was analyzed by X-ray diffraction,and its interface morphology was examined with a scanning electron microscope.Furthermore,single point scratch test and friciton and wear test we…
