This work aimed to (a) characterize the microstructure and porosity of human nail and bovine hoof by mercury intrusion porosimetry and SEM image analysis, (b) study the effects of hydration and of N-acetyl-l-cysteine treatment on the microstructure of both membranes, and (c) determine whether the microstructural modifications were associated with changes in drug penetration measured by standard...

Surface material loss due to erosive wear is responsible for the increased cost of maintenance and downtime in industries. Hence, hardfacing one most valuable effective techniques employed improve resistance heavy-duty components. The present paper investigates microstructural characteristics a hypereutectic high-chromium cast iron, considering erosion resistance, resulting from impact micro-si...

Five layers, i.e. floss, upper, middle, lower and pelade, exist in cocoon shell from outer to inner portion. An attempt has been made for assessment of microstructural characteristics eri silk fiber different layers cocoons. Wide angle x- ray diffraction revealed increase crystallinity as well degree orientation decrease crystal size besides lattice spacing remains at par floss pelade layers. S...
