In this work, the effects of Cu addition on the microstructure, mechanical properties, and degradation behavior of the hollow glass microspheres/Mg alloy composites (HGM/MA) are investigated. The results indicate that with the Cu content increases from 0 to 2 wt.%, the grain size reduce from 17.89 ± 1.15 to 12.05 ± 0.85 μm, the compressive strength and Brinell hardness increase from 303 ± 5.5 MPa...
Recently, although the technique and the equipment of copper smelting in China has been among advanced international levels, there are still some problems on high energy consumption and instable quality of products. These problems need to be solved by improving automation technique urgently. Soft measurement of key parameters is one of these technologies to improve the automation level of copper smelting...
In this paper, based on the structure of lithium-ion batteries, the electrode materials were separated from spent lithium-ion batteries (LIBs) with aim to recycle all valuable components as possible. The spent LIBs were dismantled first, then the mechanical pulverization and sieving process was adopted in the separation of anodes, and dissolution method was used to partition active components from...
Vegetation reflectance spectra in field with spectrometer to be tested in this study, used eight kinds of spectral parameters to analysis spectral of vegetation, six kinds of heavy metal content in plant leaves to be measured, then the regression model from the spectral characteristic parameters to the heavy metal content can be built, according to this can inverse heavy metal content with spectral...
The investigation of the relation of catalyst particles with resultant carbon deposits has been carried out. In this paper, the influences of catalyst particles on the morphology of carbon fibers are studied. Carbon fibers have been synthesized by the decomposition of methanol/ethanol over copper substrate via catalytic combustion technique and chemical vapor deposition method. The structural characteristics...
