This study utilizes XRF analysis of 44 pottery samples from the Shang–Zhou Longhucun workshop in Chengdu to characterize a consistent high-silica, iron-rich raw material source while identifying diachronic shifts in production variability and technological links to the broader Sanxingdui and Jinsha cultures.
This study characterizes six crosslinked electrospun nanofibrous mats of PVA and PEO incorporating Gelatin and TiO2, revealing that while glutaraldehyde crosslinking failed for PEO due to a lack of reactive groups, it significantly enhanced the tensile strength of PVA/TiO2 nanocomposites by 221%.
This study demonstrates that bio-based solvents synthesized from sorbitol and oleic acid (SOA2 and SOA3) offer a sustainable alternative for separating thorium from rare earth elements with high selectivity, despite exhibiting lower overall extraction capacity compared to conventional organophosphorus extractants like Cyanex and D2EHPA.
This study demonstrates that solvent-free co-evaporation enables the creation of a vertically compositional 2D/3D interface in perovskite/silicon tandem solar cells, achieving a record 30.93% efficiency and exceptional long-term stability by eliminating bulky organic cations while ensuring coherent crystal connectivity and suppressing defect formation.
This paper presents a sustainable, acid-reduced modification of the Hummers Method for synthesizing well-exfoliated Graphene Oxide that significantly minimizes hazardous waste and safety risks while maintaining effective oxidation.
This study reports the synthesis, characterization, and biological evaluation of a novel series of benzoxazolone-hydrazone hybrids, identifying specific derivatives (notably compound 14) as potent dual inhibitors of aromatase and monoamine oxidase enzymes with promising antiproliferative activity against breast cancer cells and favorable drug-likeness profiles.
This study demonstrates that a sequential chemical oxidation followed by polyamine-based coagulation–flocculation, specifically using a linear polyamine coagulant, effectively removes 98.5% of cyanide and 98.8% of color from steelmaking wastewater, offering a scalable and economically viable treatment solution.
This study demonstrates that a hybrid electrochemical-photochemical system utilizing a magnetite-impregnated graphite anode effectively degrades metformin hydrochloride by 95.22% within 75 minutes, following pseudo-first-order kinetics and resulting in a treatment effluent that is non-toxic to yellow onions but remains toxic to broccoli cabbage.
This paper evaluates archived characterization and catalytic data for octahedral ceria-supported CuNi, FeCu, and AuRu catalysts in CO₂ hydrogenation, identifying specific elemental discrepancies and unresolved methodological issues regarding sample identity and carbon balance that prevent definitive conclusions despite partial data corrections.
This study demonstrates a minimally invasive, multi-analytical approach combining XRF, Raman, LIBS, UVF photography, and X-ray CT to characterize the materials, pigments, and internal structure of a fragile 19th-century papier-mâché *Amanita muscaria* model from the Arnoldi collection while optimizing laser parameters to prevent damage.
