Summary: This research explores a green synthesis method for controlled synthesis of copper chalcogenides by electrochemical oxidation of copper substrate in a alkaline solution containing sulfide ions. The size and shape of the synthesized CuxS particles can be adjusted by manipulating the applied potential window or scan rate. The successful synthesis of CuxS was confirmed through cyclic voltammetry and X-ray spectroscopy analysis.

Summary: Covalent attachment of a ferric hemoglobin (metHb) core to three human serum albumin molecules has been used to develop an antidote for hydrogen sulfide poisoning. This study investigated the pharmaceutical integrity of lyophilized metHb-albumin clusters and their reconstitution with different fluids. The results showed that metHb-albumin clusters retained their properties and structure when reconstituted with sterile water for injection or 0.9% sodium chloride injection, but showed changes and higher mortality rate when reconstituted with 5% dextrose injection.

Summary: This study develops an electrochemical biosensor using Cu2O nanoparticles as the nanomaterial, thionine as an electron mediator, and chitosan as a cross-linking agent to immobilize cholesterol oxidase. The biosensor exhibits excellent electrochemical characteristics, good linearity, high sensitivity, and low detection limit for cholesterol detection. It also shows strong anti-interference, good reproducibility, stability, and high recovery rate in actual samples, making it suitable for highly sensitive cholesterol detection.

Summary: In this study, a hybrid catalyst composed of α-Fe2O3 and Cu2S was synthesized and showed excellent surfactant removal performance in a heterogeneous persulfate-AOP system. The AOP containing the catalyst FC75 achieved 100.0% removal of SDS, significantly higher than using α-Fe2O3 or Cu2S alone. The catalyst also demonstrated effective performance in recycling tests and actual wastewater, indicating its potential for surfactant degradation.

Summary: In this study, the Cu content was controlled to reduce the superionic phase transition temperature and extend the high ZT temperature range, in order to improve the average ZT of Cu-rich cuprous sulfide materials. However, increasing Cu vacancies inevitably increases the carrier concentration and carrier thermal conductivity, reducing the ZT value of the material. Therefore, it is necessary to reasonably control the Cu content to balance the carrier concentration and superionic phase transition temperature.

Summary: This study investigated the feasibility of preparing copper foil by treating cuprous sulfide superionic conductor with an electric field. Smooth, complete, and uniform copper foil with different thicknesses was successfully prepared. The concentration of copper and the energy barrier of copper precipitation were found to be the key factors determining the characteristics of the copper foil. This method provides a new option for the preparation of high-quality copper foil, which can be used in lithium batteries and printed circuit boards.

Summary: Cu2O rhombic dodecahedra and cubes functionalized with 4-nitrophenylacetylene were used as photocatalysts for the oxidation of aryl sulfides to produce aryl sulfoxides. Under the supply of oxygen and blue LED light, the reaction could be completed in 12 hours in a water and methanol mixed solution. High product yields and excellent selectivity for sulfoxides over sulfones were achieved, with a thioanisole to methyl phenyl sulfoxide yield of 98%. Mechanistic study revealed the involvement of photogenerated electrons, holes, and superoxide radicals in the oxidation reaction. The simple preparation of the photocatalyst and molecular functionalization demonstrate the effectiveness of surface-controlled ionic solids as photocatalysts for organic transformations.
