This paper elucidates the mechanism of molecular oxygen formation within the oxygen-evolving complex, detailing how a peroxo-bond converts to a superoxo-bond and subsequently to O₂ during the S₄ to S₀ transition, thereby completing the S-state cycle.
This study presents a highly sensitive sandwich-style colorimetric immunosensor utilizing a visible-light-activated CdS/Ag₂S/g-C₃N₄ ternary heterojunction nanozyme to achieve rapid and accurate detection of the pancreatic cancer biomarker CA19-9 in clinical serum samples.
This study presents a water-induced supramolecular self-assembly strategy that integrates porphyrin aggregates with a multifunctional MIL-101(Fe)@MoS₂ metal–organic framework to overcome aggregation-caused quenching and create an ultrasensitive electrochemiluminescence aptasensor for detecting 4-fluoromethamphetamine in e-cigarette samples.
This study investigates the stabilization mechanisms and rheological behaviors of AM/AMPS-based gels with varying AMPS content, revealing that while higher AMPS content (60%) enhances thermal stability, lower AMPS content (30%) yields stronger plugging pressure due to a more brittle rheological profile, thereby providing critical insights for optimizing gel properties for high-temperature, high-salinity oilfield water shutoff applications.
This study reports the synthesis of carboxylated magnetic polymer microspheres with tunable poly(acrylic acid) shells that exhibit rapid, high-capacity, and selective adsorption of cationic dyes via electrostatic attraction, while maintaining excellent magnetic recoverability and reusability.
This study demonstrates that recycled Nd–Fe–B nanocrystalline particles, despite exhibiting lower spatial resolution than commercial powders due to larger particle sizes, are viable for 4D magnetic printing and can effectively enable the fabrication of magnetically actuated soft robots and devices.
This study demonstrates that incorporating 7.5% honey into PCL-PVA nanofiber solutions stabilized in formic acid/acetic acid solvents prevents time-dependent acidic hydrolysis, thereby maintaining spinnability for over 21 days while enhancing the resulting scaffolds' mechanical strength, hydrophilicity, and biocompatibility compared to honey-free controls.
This study demonstrates that the phase-selective mechanosynthesis of Zn-BDC coordination polymers via liquid-assisted ball milling is governed by the specific liquid additive used, where water yields a 1D structure while DMF or optimized water-DMF mixtures selectively produce the 2D metal-organic framework MOF-2 with gas adsorption properties comparable to solution-synthesized samples.
This study demonstrates that incorporating carbon quantum dots into UiO-66-NH2 creates hybrid materials capable of visible-to-ultraviolet upconversion and interfacial photophysical coupling, significantly enhancing visible-light photocatalytic degradation of pollutants compared to the pristine framework.
This study demonstrates that optimized chitosan-supported zero-valent iron nanocomposites (nZVI@CS) packed in recirculating columns offer a technically feasible and economically competitive decentralized alternative for removing hexavalent chromium from laboratory waste, achieving high removal capacity while reducing treatment costs by up to 57% compared to conventional methods.
