This study presents an atomic-layer-deposited ZnF₂-coated aluminum current collector that electrochemically transforms into a synergistic NaF/Na–Zn interphase, enabling highly reversible sodium plating and achieving exceptional cycling stability in high-energy-density anode-free sodium batteries.
This study reports the synthesis of microflower-like NiCo alloy nanoparticles anchored on nitrogen-doped carbon nanotubes (NiCo@NCNTs) via hydrothermal and calcination methods, which function as highly efficient and stable bifunctional electrocatalysts for overall water splitting, achieving a cell voltage of 1.70 V at 10 mA cm⁻².
This study demonstrates that Ni8CrMoV high-strength steel exhibits superior corrosion resistance compared to Ni2CrMo steel in marine environments due to its higher Ni and Mo contents, which promote the formation of a protective rust layer and isolated pitting, whereas the lower alloying content of Ni2CrMo leads to rapid pit coalescence and accelerated transition to uniform corrosion.
This paper presents the development and validation of a simple, accurate, and stability-indicating HPTLC method for the simultaneous quantification of Polmacoxib and Paracetamol in bulk and tablet formulations, demonstrating excellent linearity, specificity, and robustness under various stress conditions.
This study demonstrates that a ternary synergistic flame retardant system combining ammonium polyphosphate, nanosepiolite, and MXene significantly enhances the flame retardancy and mechanical properties of ethylene vinyl acetate copolymer by forming a dense, reinforced carbon layer, offering a promising solution for high-performance new energy cable protection.
This study demonstrates the successful fabrication of novel organic-inorganic hybrid beads, composed of crosslinked chitosan, kaolin, and grafted HEMA, which effectively co-adsorb Congo Red and Crystal Violet dyes from binary mixtures with high efficiency under acidic conditions, following pseudo-second-order kinetics.
This study demonstrates that optimizing submerged arc welding parameters, particularly by increasing welding speed to reduce heat input, significantly enhances the mechanical properties and corrosion resistance of API 5L X60 steel in sulfur-rich environments by refining the microstructure and mitigating the severe degradation caused by high sulfur exposure.
This study synthesizes and characterizes both lead-based Methylammonium Lead Iodide and lead-free Methylammonium Bismuth Iodide perovskites using a precursor solution method, conducting a comparative analysis of their structural and optical properties to evaluate the latter as a safer alternative for photovoltaic applications.
This study demonstrates that functionalized graphite–palladium nanocomposites, synthesized via a wet-chemical route and featuring well-dispersed Pd nanoparticles, function as effective room-temperature hydrogen sensors with optimal performance at 33 wt% Pd, driven by a charge-transfer mechanism involving PdHx-mediated work-function modulation and defect-assisted electron transfer.
This study demonstrates that adding nitrogen and vanadium to a cast austenitic high-manganese steel significantly enhances its strength, ductility, and cryogenic impact toughness through interstitial solid-solution strengthening, vanadium nitride precipitation, and twinning-induced plasticity, resulting in a notably higher stacking fault energy compared to baseline and commercial alloys.
