The high-temperature reduction is rapid due to gas-solid reactions, and occurs closer to the plasma discharge, and the low-temperature reduction occurs in the solid phase and is likely kinetically inhibited from proceeding to form phosphides. Known temperature points are the melting point of the ...
Weihong Yang PhD, in Sustainable Resource Recovery and Zero Waste Approaches, 2019 Mechanical Separation and Sorting The next step of WEEE processing is the sorting/separation based on the differences in the physical characteristics of the materials, such as weight, size, shape, density, electric ...
Volcanoes represent one of the largest natural sources of metals to the Earth’s surface. Emissions of these metals can have important impacts on the biosphere as pollutants or nutrients. Here we use ground- and drone-based direct measurements to compare the gas and particulate chemistry of the ...
All functionally specialized, mature blood cells (red blood cells, granulocytes,macrophages, dendritic cells, and lymphocytes) arise from a single cell type, the HSC. The process by which HSCs differentiate into mature blood cells is called hematopoiesis. Two primary lymphoid organs are responsible fo...
