Nanoporous silicon powder was produced via efficient magnesiothermic reduction. In this work, the thermal effect and reduction process time were investigated on the porous silicon structure. The nanoporous silicon powders were characterized by  X-ray diffraction analysis and field emission scanning electron microscopy. The results demonstrate that porous structure was changed to homogeneous and...

The magnitudes of basic slag (BS) at 0, 10, 20 and 30 t ha-1 on iron dynamics in two acid sulfate soils (ASSs) under moisture field capacity, saturated condition wetting-drying cycle were studied during months incubation (25-30 0C). impacts BS Sarisabari ASS almost similar as those obtained Purbapukuria various treatments, but the increments pHs not pronounced observed ASS. pH values increased ...

in this study, the recycling possibility of residual oil fly ash (rofa) towards preparing activated carbon and its application in environmental remediation through adsorbing cu (ii) and pb (ii) ions from aqueous solutions were investigated. activated carbons were prepared using two different physical activation methods such as under steam flow at 950 0c, and combined steam and co2 flow at 850 0...

Postharvest quality in stone fruits is ultimately defined in terms of consumer satisfaction, and includes appearance, texture and flavor, and nutritional value and safety. These result from all decisions and practices beginning with site and cultivar selection, and extending through cultural practices and all stages of postharvest handling. The development of high quality fruit is influenced by...

Structural inhomogeneities are observed in RF sputtered C079Cr21 layers, studied for perpendicular magnetic recording. The effective perpendicular anisotropy is strongly affected by the occurrence of inhomogeneities in the growth direction (e.g. an initial layer), which can be diminished by changing the substrate or by using a Ge underlayer. Lateral inhomogeneities (e.g. due to segregation) hav...
