This study reports the sol-gel synthesis of a thermally stable PANI@Zn-NA-MOF nanocapsular composite that demonstrates bifunctional electrocatalytic efficiency for both oxygen and hydrogen evolution reactions, offering a promising pathway for sustainable hydrogen production via water electrolysis.
This study provides the first coordinated chemical and ATR-FTIR characterization of olive oils from small-scale producers in San Lorenzo Maggiore, Southern Italy, establishing an analytical baseline for this previously undocumented region while demonstrating that the collected heterogeneous samples are better suited for descriptive spectral profiling than for quantitative prediction of free acidity.
This study demonstrates that the heterogeneous hydrogenation of HTPB using a Pd-Zr-charcoal catalyst in a bi-solvent system achieves an 87.5% degree of hydrogenation under hydrogen-air conditions within 6 hours, resulting in a thermally stable, waxy solid with preserved hydroxyl values and a marginal increase in molecular weight.
This study optimized the cellulase hydrolysis process for tobacco stems using Response Surface Methodology to achieve a 36.2% reducing sugar yield and 70.7% cellulose degradation, thereby significantly improving stem quality for cigarette production by reducing ligneous taste and enhancing industry sustainability.
This study reports a purely supramolecular hydrogel that achieves both strain stiffening and structural plasticity through orthogonal physical crosslinks and inter-fibril sliding, offering a new design framework for bioinspired adaptive soft matter.
By combining real-time isomer characterization with kinetic modeling, this study reveals that acid-driven IEPOX isomerization on sulfate aerosols produces highly volatile compounds, leading to a significant downward revision (up to 65%) of simulated isoprene-derived secondary organic aerosol in major global regions and highlighting the need to account for other formation processes.
This study reports the synthesis of a durable, covalently bonded flame retardant and antimicrobial finishing agent (FRA-PHMG) that significantly enhances the fire safety and microbial resistance of cotton fabrics while maintaining mechanical properties and enduring over 50 washing cycles.
This paper presents the development and full validation of a highly sensitive, selective, and regulatory-compliant LC-MS/MS method for the accurate quantification of the genotoxic impurity N-Nitroso Fluoxetine in Fluoxetine Oral Solution, demonstrating excellent linearity, precision, and specificity for routine quality control.
This study establishes a reproducible HPTLC fingerprint for the methanolic extract of the brown marine alga *Padina tetrastromatica*, qualitatively identifying key phenolic compounds such as quercetin, rutin, and gallic acid to support its authentication and potential as a source of bioactive pharmaceutical agents.
This study reports the successful fabrication of a BiOBr/MoWO4 p-n heterojunction photoanode via in situ hydrothermal synthesis, which significantly enhances visible-light-driven photoelectrocatalytic degradation and mineralization of norfloxacin in wastewater through improved charge separation and synergistic effects compared to individual components.
