- Precipitating Rare Earth by NH4HCO3 from a Concentrated Rare Earth and . . .
The ammonium bicarbonate precipitation method has become one of the main ways to extract rare earths from rare earth leaching solutions due to its advantages of simple operation, mature technology, and low cost Therefore, the objective of this study was to explore the precipitation of rare earth carbonate (REC) from a concentrated rare earth and magnesium sulfate solution by ammonium
- Research on Microstructure and Properties of AlSi10Mg Fabricated by . . .
In order to obtain high-performance aluminum alloy parts fabricated by selective laser melting, this paper investigates the relationship between the process parameters and microstructure properties of AlSi10Mg The appropriate process parameters are obtained: the layer thickness is 0 03 mm, the laser power is 370 W, the scanning speed is 1454 mm s, and the hatch spacing is 0 16 mm With these
- Lactic Acid Salts of Nicotine Potentiate the Transfer of Toxic Metals . . .
The designs and liquid formulations of Electronic Nicotine Delivery System (ENDS) devices continue to rapidly evolve Thus, it is important to monitor and characterize ENDS aerosols for changes in toxic constituents Many ENDS liquid formulations now include the addition of organic acids in a 1 to 1 molar ratio with nicotine Metal concentrations in aerosols produced by ENDS devices with
- The Use of ZnO Quantum Dots to Improve the Electrical Properties of . . .
Silicon-based solar cells dominate the photovoltaic market, with commercial monocrystalline silicon cells reaching efficiencies as high as 27 3% by May 2024 An alternative to monocrystalline silicon solar cells is polycrystalline solar cells Despite their lower efficiency (record: 23 81%), their manufacturing process is simpler and cheaper, and their energy conversion efficiency is less
