Synergistic rGO/MoS E-Shaped Evaporators: Efficient Solar Desalination and Water Purification via Enhanced Photothermal Conversion and Structural Optimization.

Solar-driven interfacial evaporation has garnered significant attention as a sustainable technology for freshwater production. However, its widespread application is impeded by challenges, such as complex fabrication processes, high costs, and vulnerability to pore clogging. Herein, we present an E-shaped evaporator constructed through in situ integration of a binary photothermal nanocomposite comprising reduced graphene oxide and molybdenum disulfide (rGO/MoS) onto a polyurethane sponge substrate.

Design and Synthesis of a NTR-Sensitive Fluorescent HS Donor as a Potential Therapeutic Agent for Myocardial Ischemia-Reperfusion Injury.

Myocardial ischemia is a key feature of myocardial ischemia-reperfusion injury (MIRI), which upregulates nitroreductase (NTR) expression. Targeting this mechanism, the design of NTR-responsive prodrugs has emerged as an innovative strategy for MIRI treatment. Herein, we synthesized HSD-NTR-B, a novel NTR-responsive hydrogen sulfide donor.

A superoxide anion responsive and self-reporting fluorescent HS donor for the treatment of diabetic wound.

Superoxide anion (O) not only serves as a critical precursor for numerous damaging reactive oxygen species (ROS), but also is implicated in a variety of diseases, including cancer, cardiovascular disorders, and diabetes. Consequently, reducing the levels of superoxide anions and alleviating oxidative stress are of paramount importance. Conversely, hydrogen sulfide (HS), recognized as a significant biological signaling molecule, plays vital roles in protecting mammalian cells from oxidative damage and promoting tissue regeneration.
