Agricultural soil is contaminated with dangerous heavy metals (HMs) from anthropogenic activities and natural processes. These HMs are passed to humans through the consumption of crops produced in soil. Crop production a field irrigation raw untreated sewage industrial effluents exposed food contaminations. Consumption foods can be due their persistent nature tendency accumulate human tissues. ...

Since the discovery of the first metallic glass in 1960 (1), amorphous metals have been made in a variety of compositions. However, they have been largely fabricated as thin ribbons less than a millimeter in thickness because fast cooling rates (;10 K/sec) have been required to retain the metastable amorphous phase. Recently, however, a new class of amorphous metals has been developed which req...

Xylose isomerase from Piromyces sp. E2 (PirXI) can be used to equip Saccharomyces cerevisiae with the capacity to ferment xylose to ethanol. The biochemical properties and structure of the enzyme have not been described even though its metal content, catalytic parameters, and expression level are critical for rapid xylose utilization. We have isolated the enzyme after high-level expression in E...

Production of high quality interpolation maps of heavy metals is important for risk assessment of environmental pollution. In this paper, the spatial correlation characteristics information obtained from Moran's I analysis was used to supplement the traditional geostatistics. According to Moran's I analysis, four characteristics distances were obtained and used as the active lag distance to cal...

The atomistic mechanisms active during plastic deformation of nanocrystalline metals are still a subject of controversy. The recently developed approach of combining automated crystal orientation mapping (ACOM) and in situ straining inside a transmission electron microscope was applied to study the deformation of nanocrystalline Pd x Au1- x thin films. This combination enables direct imaging of...
