Abstract
Concerns have arisen regarding the high concentrations of sodium sulfate in wastewater resulting from the waste Li-ion battery wet recycling process. In addressing this issue, Bipolar electrodialysis was employed to desalinate high-concentration sodium sulfate and recover it as sulfuric acid and sodium hydroxide. The investigation encompassed various experimental variables, such.....

DOI:
https://doi.org/10.3365/KJMM.2023.61.4.231
Abstract
Global warming and air pollution have forced greater attention to new energy sources to replace fossil fuels. Among several eco-friendly energy sources, polymer electrolyte membrane fuel cells have been increasingly investigated since they have zero emissions, high energy density, and high energy efficiency. Carbon-supported Pt catalyst is generally used for.....

Abstract
Due to environmental pollution and global warming, research on new energy sources that can replace fossil fuels is important. A fuel cell is an eco-friendly energy conversion system that discharges water, and uses hydrogen as fuel. Although platinum is a widely used catalyst in PEMFCs, it has commercial limitations because.....

Abstract
In micro/nano electro-mechanical system, silicon nitride (SiNx) membrane has been widely used in sensors, energy harvesting and optical filters because of its mechanical/chemical stability. However, it is necessary to verify mechanical and thermal properties of nanoscale SiNx membranes to ensure the desirable reliability and durability of a device because the.....

https://doi.org/10.3365/KJMM.2018.56.5.406
Abstract
Industrially meaningful hydrogen production process from mixture or syngas certainly must have a cooling process, which is typically pressure swing adsorption (PSA). However, the PSA process involves an exothermic reaction during adsorption. Recently, hydrogen separation research has been in progress in order to develop a cooling process to minimize or.....
