摘要： An abrupt interface electroreduction catalyst includes a porous gas diffusion layer and a catalyst layer providing a sharp reaction interface. The electroreduction catalyst can be used for converting CO 2 into a target product such as ethylene. The porous gas diffusion layer can be hydrophobic and configured for contacting gas-phase CO 2 while the catalyst layer is disposed on and covers a reaction interface side of the porous gas diffusion layer. The catalyst layer has another side contacting an electrolyte and can be hydrophilic, composed a metal such as Cu and is sufficiently thin to prevent diffusion limitations of the reactant in the electrolyte and enhance selectivity for the target product. The electroreduction catalyst can be made by vapor deposition methods and can be used for electrochemical production of ethylene in reaction system.

摘要： Disclosed herein is a low cost and rapid microfluidic based method and test device for quantifying male fertility potential. The device can simultaneously measure three critical semen parameters rapidly, namely live sperm concentration, motile sperm concentration, and sperm motility. The device includes a transparent substrate and a top sheet with two holes therethrough and an intermediate sheet sandwiched between the substrate and the top sheet. The wells formed by holes form a concentration measuring well (C) and a motility well (M) formed by the top sheet with these two holes bonded to the intermediate sheet. A colorimetric agent is located on the top surface of the intermediate sheet at the bottom of each well which changes color when in contact with sperm. In the motility well a porous membrane is located on top of the colorimetric agent and a liquid buffer may be placed on the top surface of the porous membrane. Applying part of a sperm sample to the C well results in direct contact of any live sperm with the colorimetric agent causing a color change, applying part of the sperm sample to the M well results in live sperm with sufficient motility to swim vertically down through the liquid buffer and through the porous membrane to the colorimetric agent. Evaluating the intensities of the color change of the colorimetric agents before and after contact with the sample gives a measure of total concentration of live sperm and motile sperm from which sperm motility is calculated.
