Introduction: Micrometeoritic impacts on lunar soils produce melt and vapor [1]. A patina of condensed vapor is deposited on lunar grains [2], the melt forms agglutinitic glass [3]. In lunar soils, agglutinitic glass and rinds of grains host submicron-sized globules of pure Fe (Fe-rich globules larger than 1 micron usually contain other elements such as Ni, P, and S). Observation and measuremen...

This study investigates the hypothesis that the mechanisms of chemical coagulationflocculation and electrocoagulation produce specific imprints in nature, and the structure of sludge aggregates-floccules (flocs). Scanning electron microscopy (SEM) methods were used to produce 480 images of 32 types of wastewater sludge. The analyzed sludge was obtained by chemical coagulation and electrocoagula...

novel nano-catalysts (nano zno and fe doped zno (fe(0.1)zn(0.99)o) synthesized by co-precipitation method in aqueous solution as new nanocatalysts and characterized by common techniques as ftir, xrd, sem and uvd. the size of particles obtained from xrd data is 27 and 16 nanometers for zno and fresno respectively. influences of doped fe on zno catalytic properties in oxidation of benzylic alcoho...
