This study demonstrates that a balanced 50% sisal and 50% false banana fiber hybrid epoxy composite exhibits superior flexural strength, stiffness, and toughness compared to single-fiber counterparts, making it an effective sustainable material for structural applications.
This study demonstrates that mixing specific tannery effluents from different processing stages, particularly liming with chrome tanning and neutralization with chrome tanning, can achieve up to 99.99% chromium removal and significant reductions in organic and physical pollutants without requiring additional chemical or biological treatments.
This paper demonstrates an efficient, reagent-free electrochemical method for preparing UCl₃-LiCl-KCl molten salt in a frit-separated cell using a bismuth cathode, which successfully achieves high current efficiencies and precise concentration control without introducing metallic impurities or corrosive gases.
This study demonstrates that a Mn/SnS/graphite composite synthesized via high-energy ball milling significantly enhances the lithium storage performance and cycling stability of SnS anodes by utilizing Mn to improve electrical conductivity and buffer volume expansion.
Through semi-rational design, researchers engineered the halohydrin dehalogenase IcHheG into an L103H/N196W double mutant that achieves highly enantioselective synthesis of (R)-5-phenoxymethyl-2-oxazolidinone (99% ee) via the kinetic resolution of 1-chloro-3-phenoxy-2-propanol, with molecular docking revealing that mutations in the substrate-binding pocket enhance selectivity by altering substrate positioning relative to catalytic residues.
This study presents a rapid, robust, and green AQbD-guided RP-HPLC method utilizing a chaotropic agent (KPF₆) for the simultaneous determination of rosuvastatin, atorvastatin, and ezetimibe, which was systematically optimized via Box-Behnken design and validated for routine quality control with confirmed environmental sustainability.
This study developed and validated a rapid, solvent-efficient solid-phase extraction method for quantifying oil and grease in Copacabana beach sand, which yielded results statistically comparable to the traditional Soxhlet extraction technique.
Lanthanum doping of cobalt ferrite nanoparticles synthesized via a protein-assisted sol-gel route effectively enhances superparamagnetic behavior and significantly increases the electrochemically active surface area, with the composition exhibiting optimal multifunctional properties for magnetic and electrocatalytic applications.
This study demonstrates that stir-cast Al7068 hybrid composites reinforced with varying micro-particle percentages of Si₃N₄ and SiC, particularly when shot-peened, exhibit uniform microstructures and enhanced impact resistance, making them promising candidates for lightweight aerospace applications.
This study employs Density Functional Theory to investigate the electronic structures and thermodynamics of oxygen reduction intermediates in an Fe-porphyrin biomimetic model of cytochrome c oxidase, revealing favorable reaction energetics and moderate interaction strengths that offer molecular-level insights for designing efficient Fe-based catalysts.
