This study reports the fabrication and characterization of Mo-free Cu₂ZnSn(S,Se)₂ solar cells using elemental precursors and a solution-process method, demonstrating that selenium addition optimizes crystallinity, reduces bandgap, and enhances efficiency, with a locally sourced variant achieving performance comparable to the selenium-rich sample.
This study demonstrates that homogeneous Sr²⁺ doping, achieved by controlling diffusion along radially oriented primary grains in Ni-rich NCM831106 cathodes, significantly enhances structural stability and high-rate electrochemical performance, a finding further validated through deep learning analysis of particle morphology.
By optimizing the thiourea-to-metal ratio in the precursor solution to tailor film porosity, this study enhances the vertical crystallization uniformity and defect properties of MOE-based CZTSSe absorbers, thereby boosting solar cell efficiency from 8.1% to 12.1%.
This study demonstrates that a rigid-flexible synergistic design strategy using 3,3′-DDS and BAPT monomers enables the systematic tuning of mechanical, thermal, and dynamic properties in polyimine vitrimers, yielding recyclable materials with balanced performance, high flame retardancy, and efficient reprocessability.
This study demonstrates the successful fabrication of biocompatible, hemostatic, and highly antibacterial CMC/Alg hydrogel films incorporating in-situ synthesized ZIF-8 nanoparticles, presenting a promising candidate for advanced wound dressing applications.
This paper reports a photoinduced "sew-and-cut" strategy that enables controllable, tunable carbon-increasing homologation of electron-deficient alkenes by utilizing cycloalkyl hydroperoxides as carbon sources to directly insert (CH₂)ₙ units (n = 1–8) through a sequence of radical-mediated C–C bond cleavage, Giese-type addition, and Norrish type II reaction.
This study demonstrates that synergistic functionalization of corn straw fibers using a gallic acid–laccase system significantly enhances their mechanical toughness and interfacial compatibility, thereby markedly improving the high-temperature rheological performance and molecular stability of SBS-modified asphalt binders through strengthened intermolecular interactions.
This study demonstrates the successful fabrication of a tungsten-modified Fe-rich Cantor-type high-entropy alloy with a homogeneous single BCC solid-solution microstructure and enhanced mechanical properties using metal powder cored wire feedstock in wire arc additive manufacturing.
This paper reports a novel polymerization strategy that utilizes a hydrogen atom-coupled electron transfer (HCET) process to bridge radical and anionic mechanisms, enabling the synthesis of diverse polymers under aerobic conditions with Earth-abundant reagents and unpurified chemicals.
This study demonstrates that human myeloperoxidase (MPO), released by neutrophils during skin sensitization, enzymatically oxidizes specific aromatic diamines and phenylpropanoids into protein-reactive metabolites, thereby revealing a previously unrecognized biological activation pathway that complements existing abiotic and epidermal metabolic mechanisms.
