Can isotropic wet chemical etching be controlled with a spatial resolution at the nanometer scale, especially, for the repetitive microfabrication of hierarchical 3D m-nanostructures on the continuously curved surface of functional materials? We present an innovative wet chemical etching method called “electrochemical buckling microfabrication”: first, a constant contact force is applied to gen...
Hundreds of people are killed or injured annually in the United States in accidents related to ice formation on roadways and bridge decks. In this paper, a novel embedded sensor system is proposed for the detection of black ice as well as wet, dry, and frozen pavement conditions on roads, runways, and bridges. The proposed sensor works by detecting changes in electrical resistance between two s...
In many urban areas, groundwater has been exploited neglecting to wet and dry periods owing to of surface water deficit. In this study, using the percent of normal rainfall index, 36 year (1971-2008) were studied and a drought event and a wet event were determined. The reason to choose two consecutive years is the effect of early wet period on groundwater quality. Physicochemical characteristic...
