This study demonstrates that atmospheric UV irradiation of CO₂, CO, and H₂O on the early Earth or Mars can spontaneously generate a self-sustaining "Primitive Respiration Cycle" of aldehydes, organic acids, and amino acids, offering a plausible non-enzymatic pathway bridging geochemistry and the emergence of ancestral metabolism.
This study utilizes an optimized carbon quantum dot fluorescence method to demonstrate that soil nitrogen, pH, ferrous iron, and humic substances collectively promote the reduction and passivation of toxic hexavalent chromium (Cr(VI)) to trivalent chromium (Cr(III)), thereby reducing its mobility and bioactivity in agricultural soils.
This study demonstrates that dual-function metal–organic frameworks (MOFs), particularly those with single-linker structures and high nitrogen content like Co-MOF-I, significantly enhance ammonium perchlorate decomposition and fuel efficiency in composite solid propellants by lowering decomposition temperatures and increasing combustion pressure.
This study presents the development and validation of a robust, stability-indicating, and eco-friendly HPTLC method for the simultaneous quantification of Bilastine, Dextromethorphan HBr, and Phenylephrine HCl in pharmaceutical formulations, utilizing an AQbD approach and achieving a greenness score of 0.62 via AGREE software.
This study presents the first systematic evaluation of nine SMILES tokenization strategies across three model scales, revealing that while rule-based tokenizers excel in generative validity, corpus-based and hybrid approaches outperform in downstream property prediction, ultimately recommending a hybrid strategy for generalizable chemical language models.
This study employs ωB97X-D molecular modeling to demonstrate that hydrogen-atom transfer is the dominant antioxidant mechanism across various solvents for eleven phenolic compounds, with thermodynamic efficiency governed by substituent patterns that enhance phenoxy radical stabilization through reduced spin localization and effective π-delocalization.
This study demonstrates that corrugated helical zeolite pellets significantly outperform conventional smooth spherical pellets by increasing hydraulic conductivity by 55%, reducing pressure drop by 35%, and improving phosphate removal efficiency by 25% through geometric optimization alone.
This study demonstrates that iron-modified biochar derived from coconut fiber in Vietnam effectively removes copper and zinc from wastewater through enhanced surface area and mineralization, achieving high adsorption capacities that are successfully predicted and mechanistically explained by machine learning models.
This study demonstrates that HCl-activated drinking water treatment sludge serves as an effective, reusable adsorbent for removing amoxicillin from water under optimized conditions, with adsorption behavior best described by the Langmuir isotherm and dominated by physical interactions.
This study demonstrates that covalently incorporating a small amount of poly(glycolic acid) into poly(ε-caprolactone)-based polyurethanes significantly enhances their mechanical strength and toughness while lowering the shape memory transition temperature to near body temperature, achieved through hydrogen bonding-driven structural regulation and strain-induced crystallization.
