Ultrathin electrolytic copper foils with a thickness of 6 μm were prepared by a test machine using copper sulfate electrolyte with gelatin, hydroxyethyl cellulose (HEC), and sulfonic acid-containing organics as additives. The effects of four sulfonic acid-containing organic additives, sodium 3-mercaptopropanesulfonate (MPS), bis-(sodium sulfopropyl)-disulfide (SPS), sodium 3-[[(dimethylamino)thioxomethyl]thio]propanesulfonate (DPS), and sodium 3-((4,5-dihydrothiazol-2-yl)thio)propane-1-sulfonate (TPS), on the physical property of copper foils were investigated. The results show that all these additives can effectively improve the gloss and tensile strength of electrolytic copper foil, and the texture coefficients of Cu(111) selectivity increase.

Iron sulfide (FeS) exhibits superior reactivity toward a wide range of contaminants, making it a promising candidate for environmental remediation in various media, including surface water, wastewater, soil, and groundwater. Driven by green and sustainable development principles, efficient, low-cost, and environmentally friendly biosynthesis has attracted considerable attention and has great environmental remediation potential. This review provides a comprehensive overview of the recent advances in biogenic FeS (bio-FeS), focusing on its synthesis mechanisms, performance characterization, and environmental applications.

In this study, we developed an innovative CuSe/PDA/AIPH nanoparticle platform that combines photothermal therapy and chemotherapy for effective tumor treatment. The CuSe nanoparticles, known for their strong near-infrared (NIR) absorption, were encapsulated within a polydopamine (PDA) and 2,2'-azobis[2-(2-imidazolin-2-yl)propane] dihydrochloride (AIPH) matrix. Upon NIR irradiation, the platform triggers localized heating and subsequent thermal decomposition of AIPH, releasing ROS to induce significant oxidative damage in tumor cells.

Cardiovascular diseases such as myocardial infarction or limb ischemia are characterized by regression of blood vessels. Local delivery of growth factors (GFs) involved in angiogenesis such as fibroblast blast growth factor-2 (FGF-2) has been shown to trigger collateral neovasculature and might lead to a therapeutic strategy. In vivo, heparin, a sulfated polysaccharide present in abundance in the extracellular matrix (ECM), has been shown to function as a local reservoir for FGF-2 by binding FGF-2 and other morphogens and it plays a role in the evolution of GF gradients.

Nowadays, it is challenging to achieve SO-tolerant environmental catalysis for NO reduction because of the thermodynamically favorable transformation of reactive sites to inactive sulfate species in the presence of SO. Herein, we achieve enhanced low-temperature SO-tolerant NO reduction by manipulating the dynamic coordination environment of active sites. Engineered by coordination chemistry, SiO-CeO composite oxides with a short-range ordered Ce-O-Si structure were elaborately constructed on a TiO support.
