Although formaldehyde crosslinked *Sargassum* seaweed demonstrates rapid and strong affinity for removing trace copper from urban runoff, the process is significantly compromised by the destabilization of its surface ionic layer, leading to the excessive release of organic matter and high concentrations of potassium, sodium, calcium, and magnesium ions.
MolTabReco is a multi-stage framework that integrates table-coordinate grounding, vision-language models, and optical chemical structure recognition to accurately recover molecular structures from chemical literature tables as canonical SMILES strings, significantly outperforming existing methods that fail to convert structural depictions into computable data.
This study presents a novel Ni-doped γ-Al₂O₃ multifunctional catalyst featuring frustrated Lewis pairs and spinel interlayers that achieves high-efficiency low-temperature CO₂ methanation through synergistic acid-base interactions and strong metal-support stabilization of ultra-fine Ni nanoparticles.
This study demonstrates that a domestic-scale hybrid electrocoagulation-anodic oxidation reactor, optimized with a triple-electrode configuration, effectively treats household greywater with high removal efficiencies for turbidity and organic pollutants while significantly reducing energy consumption, thereby validating its potential for decentralized water reuse applications.
This study demonstrates that cerium oxide-modified biochar, synthesized from bamboo via a hydrothermal method, significantly enhances phosphorus adsorption capacity and rate through a spontaneous, endothermic chemisorption process driven by abundant surface hydroxyl groups, offering an effective solution for phosphorus recovery and eutrophication control.
This study presents a rapid, high-performance dual-model detection system for mercury (Hg²⁺) in aquatic products that integrates a COF-AgNPs nanozyme colorimetric sensor with multimodal machine learning to achieve low detection limits, strong anti-interference capabilities, and 96.08% accuracy within 5 minutes.
This study demonstrates that continuous spatially coherent vacuum ultraviolet irradiation actively controls the dynamic evolution of radical clusters by inducing symmetry breaking and shifting reaction potential wells, thereby significantly enhancing the degradation efficiency of complex pollutants like PFAS beyond traditional kinetic limitations.
This study demonstrates that while non-isodiametric seeds with shoulder structures can reduce costs and enable grain enlargement in CdZnTe crystal growth via the Traveling Heater Method, the resulting intensified thermoelastic stress and parasitic edge grains lead to larger Te inclusions and voids that degrade detector performance, making the planar 0° shoulder configuration the optimal choice for achieving superior electrical properties.
This study systematically investigates how varying iron content (0.2–1.2 wt.%) in cast Al7Si0.3Mg alloys influences the evolution of iron-rich phases and the resulting microstructure and mechanical properties, revealing that while moderate iron levels can enhance high-temperature stability, excessive iron leads to detrimental needle-shaped β-AlFeSi phases that significantly degrade ductility, toughness, and fatigue life.
This study demonstrates that A-site Ca²⁺ doping in Bi₄Ti₃O₁₂–BaBi₄Ti₄O₁₅-based intergrowth ceramics significantly enhances orthorhombic lattice distortion and raises the Curie temperature to 708 °C, with the optimal composition (BBITKC-0.7C) exhibiting excellent high-temperature piezoelectric performance and thermal stability suitable for demanding applications.
