Porous Silicon Structures as Optical Gas Sensors
... responsible for enhanced sensitivity to ethanol vapors for analyte concentration above about 10 ppm. Since the porous Si structure has a high surface area, a large number of analyte molecules per unit volume can be expected to adsorb, owing to physisorption. Nevertheless, as a rule, physisorption fo ...

Short-time Dynamics of Frictional Strength in Dry Friction
... A series of experiments performed by Rubinstein et al. [10, 16] demonstrated that, when shear forcing is non-uniformly applied a sample’s edge, arrested (precursory) slip events occur at shear loads well below the threshold for overall slip of the entire block. These precursor events were shown to b ...
