As global demand for green hydrogen grows, scientists are exploring direct seawater electrolysis as a sustainable way to produce hydrogen without consuming scarce freshwater. Yet, seawater contains abundant chloride ions, which corrode electrodes and drastically shorten device lifetimes — a major barrier to commercialization.

In a significant stride towards enhancing the efficiency of hydrogen production, researchers are exploring the role of lignin-derived carbon Co-based composites in overcoming photocorrosion in CdS photocatalysts. The study, titled "Overcoming Photocorrosion in CdS Photocatalysts: The Role of Lignin-Derived Carbon Co-Based Composites in Hydrogen Production," is led by Prof. Xueqing Qiu and Prof. Yanlin Qin from the Guangdong Provincial Key Laboratory of Plant Resources Biorefinery at Guangdong University of Technology in Guangzhou, China, in collaboration with the Guangdong Provincial Laboratory of Chemistry and Fine Chemical Engineering Jieyang Center and the Guangdong Basic Research Center of Excellence for Ecological Security and Green Development. This research offers critical insights into improving the stability and performance of CdS photocatalysts for sustainable hydrogen production.

Tendinopathy is a common and complex musculoskeletal disorder, unfortunately current clinical strategies for tendinopathy have low therapeutic efficacy because of complicated pathogenesis. Oxidative stress is considered as the major cause of tendinopathy as well as the important target, but still lacking ideal antioxidant solution. To this end , an efficient reactive oxygen species (ROS) biocatalyst, PtIrRuRhCu high-entropy alloy nanozyme (HEANZ), has been designed for treatment of tendinopathy. The non-ionic block copolymer (polyvinyl pyrrolidone) coated PtIrRuRhCu HEANZ with size of ~4.0 nm exhibit good biocompatibility and multiple enzyme-like antioxidant activity (including peroxidase, catalase and SOD-like) to modulate ROS. The therapeutic efficacy of PtIrRuRhCu HEANZ in tendinopathy has been systematically demonstrated in vitro and in vivo.  PtIrRuRhCu HEANZ can alleviate the TBHP(t-Butyl Hydroperoxide) stimulated tendinopathy by clearing ROS, reducing inflammation and restoring mitochondrial autophagy. Using PGAM5 siRNA and FUNDC1 siRNA for intervention, we clearly revealed that PtIrRuRhCu HEANZ promoted mitochondrial autophagy through upregulating the PGAM5/FUNDC1/GPX4 axis. This study provides a nanozyme strategy for the antioxidant treatment of tendinopathy and provides insights into the therapeutic mechanism. 

Color change during fruit ripening greatly influences visual appeal and market value. In apples, the transition from green to red or yellow depends on chlorophyll breakdown, yet the molecular link between hormonal and light cues has remained elusive.
