Seawater electrolysis is a potentially cost-effective approach to green hydrogen production, but it currently faces substantial challenges for its high energy consumption and the interference of chlorine evolution reaction (ClER). Replacing energy-demanding oxygen with methanol oxidation (MOR) represents promising alternative, as MOR occurs at significantly low anodic potential, which cannot only reduce voltage needed also completely circumvents ClER. To this end, developing high-performance catalysts key. Herein, novel quaternary Pt

Pyroptosis, an immunogenic programmed cell death, could efficiently activate tumor immunogenicity and reprogram immunosuppressive microenvironment for boosting cancer immunotherapy. However, the overexpression of SLC7A11 promotes glutathione biosynthesis maintaining redox balance countering pyroptosis.

Controlling the precise growth of atoms is necessary to achieve manipulation atomic composition and position, regulation electronic structure, an understanding reactions at level. Herein, we report a facile method for ordered anchoring zero-valent platinum manganese with single-atom thickness on graphdiyne under mild conditions. Due strong incomplete charge transfer between metal atoms, formation clusters nanoparticles can be inhibited. The size, structure bimetallic nanoplates are precisely controlled by natural structure-limiting effect graphdiyne. Experimental characterization clearly demonstrates such fine control process. Electrochemical measurements show that active site platinum-manganese interface guarantees high catalytic activity selectivity (~100%) alkene-to-diol conversion.

The highly active and selective oxygen reduction reaction (ORR) is vital to promote the performance of advanced energy conversion systems, such as fuel cells other electrochemical devices. Porous framework materials have capability combine catalytic units with their porous characteristics, making them promising catalysts. However, due difficulty in designing synthesizing units, pore size modulation primarily achieved by altering linkers. We herein report design synthesis three cobalt-corrole-based organic polymers (Co-POP-1, Co-POP-2 Co-POP-3) different sizes, which were obtained extending 5,15-meso substituents Co corroles. Compared Co-POP-1 Co-POP-2, Co-POP-3 has largest size. Benefiting from enhanced mass transfer exposed sites, displayed remarkably boosted activity for four-electron/four-proton (4e−/4H+) ORR a half-wave potential E1/2 = 0.89 V versus reversible hydrogen electrode (RHE) 0.1 M KOH solutions.
