Abstract
Solar energy is attracting much attention as an eco-friendly source for future energy needs. Herein, NiZnS photocatalysts were synthesized with a hydrothermal method at various sulfur contents. The ZnS material is widely used as a photocatalyst because of its high stability, low toxicity, and excellent charge separation characteristics. Nickel is.....

https://doi.org/10.3365/KJMM.2022.60.10.774
Abstract
Metallurgical remains such as crucible, mould, slag and tuyere are generated in the production of bronze. The analysis of slag in particular can be used to identify the raw materials, processes and environments (temperature and condition) employed in the bronze fabrication . The Gwanbuk-ri site in Buyeo is known as.....

Abstract
Solar water splitting is an attractive method for producing hydrogen from renewable natural resources, and heterostructure photocatalysts have been widely investigated for photocatalytic applications. Hetero-component photocatalysts can reduce the charge recombination process by improving electron utilization, and are considered promising candidates for solar water splitting. Amongst various heterostructure systems, combinations.....

Abstract
The subject of this study was a bronze sword excavated from the early Iron Age area of Sinpung site in Wanju. SEM-EDS, FE-EPMA and Raman Micro-Spectroscopy analysis methods were applied to investigate the manufacturing techniques and corrosion characteristics. The results of the analysis indicated a casting structure composed of both.....
