A novel cationic hydrophobically associating polymer gel (PADL) was synthesized and characterized, demonstrating superior injectability, thermal stability, and salt-resistant water shutoff performance in high-salinity fractured reservoirs due to its dense 3D porous network and synergistic electrostatic and hydrophobic interactions.
This study demonstrates that low-temperature ultrasonic co-impregnation of poplar wood with glycerol and anthocyanin creates an eco-friendly, dual-functional substrate that passively buffers humidity and visually indicates moisture changes, offering an effective solution for the preventive conservation of wooden artifacts in museum display cases.
This paper presents a sequential template-mediated strategy that successfully integrates interstitial boron into ultrathin ordered intermetallic Pt-M nanosheets without sintering or disordering, resulting in highly active and durable catalysts for the oxygen reduction reaction.
This study demonstrates that a Co₃O₄/ZnS heterojunction fabricated via in situ deposition significantly enhances sacrificial-agent-free photocatalytic nitrogen reduction to ammonia by improving light utilization and charge separation, achieving a rate of 607.6 µg h⁻¹ gcat⁻¹ with a 2:1 mass ratio.
This paper presents a sustainable, one-pot synthesis of a Mirabegron advanced intermediate that integrates esterification, reductive amination, and nitro reduction to eliminate genotoxic intermediates and hazardous reagents while significantly reducing solvent usage, processing steps, and operational hazards for large-scale manufacturing.
This study reveals that Chinese purple octagonal prisms and lead-barium glass originate from a shared high-temperature reaction system, where local liquid formation, component redistribution, and selective crystallization govern the coexistence of barium copper silicates and lead-barium silicate glass within a single artifact.
This study utilizes PHREEQC modeling to demonstrate that magnetite effectively reduces U(VI) to U(IV) in Beishan groundwater, promoting uraninite precipitation and reducing uranium mobility, particularly at higher temperatures and when using appropriate thermodynamic databases, although low uranium concentrations may hinder precipitation.
This study demonstrates that optimizing the mass ratio of ZnO and SGDC in a composite electrolyte creates abundant heterointerfaces that significantly enhance ionic transport and suppress electronic leakage, resulting in a 58% increase in power density for low-temperature semiconductor-ionic fuel cells.
This study demonstrates that nitrogen-doped TiO₂ synthesized via the sol-gel method with an N:Ti ratio of 1:20 serves as a highly efficient, stable, and reusable photocatalyst for the visible light-induced degradation of the organophosphate pesticide dichlorvos in aqueous solutions.
This study demonstrates that incorporating aluminum hydroxide and carbon molecular sieve into silicone rubber foam via physical blending creates a synergistic system that significantly enhances flame retardancy and smoke suppression by forming a dense SiO₂/char barrier layer, achieving a UL-94 V-0 rating and substantial reductions in heat release and smoke production at optimal loadings.
