This study demonstrates that synthesizing chitosan-loaded Ce–Fe oxide magnetic biochar (CCFBC) significantly enhances methylene blue adsorption through a synergistic mechanism involving amino and metal-oxide functional groups, achieving a maximum capacity of 142.8 mg·g⁻¹.
This paper reports the rapid, wet-chemical synthesis of stable, self-assembled Rhodium-CTAB organosols with nanochain morphology that demonstrate superior catalytic activity in nitroarene reduction and high surface-enhanced Raman scattering performance compared to existing methods.
This study demonstrates that pyruvic acid-modified chitosan films reinforced with ZnO–MgO nanoparticles exhibit superior thermal, mechanical, barrier, and antimicrobial properties, effectively extending the shelf life of strawberries and serving as a promising sustainable material for active food packaging.
This study demonstrates that incorporating an optimal amount of activated carbon into Ni/MoC catalysts enhances methanol steam reforming activity and stability by promoting the formation of the α-MoC1−x phase and improving nickel dispersion, whereas excess carbon hinders performance by blocking catalyst pores.
This study demonstrates that zeolite pore topology acts as a molecular switch governing solvent behavior in liquid-phase catalysis, where narrow MFI channels expel solvent molecules to favor reactant adsorption while larger FAU supercages permit solvent-reactant co-occupation, a mechanism elucidated through combined NMR, thermodynamic, and machine learning-enhanced simulation analyses.
This study demonstrates that Tunisian *Hertia cheirifolia* exhibits significant chemotypic diversity in phenolic content across populations, organs, and phenological stages, with leaves harvested in October–November from Siliana or Kessra populations yielding the highest flavonol levels that strongly correlate with potent antioxidant and anti-acetylcholinesterase activities, thereby validating the plant's traditional use for neurological disorders and supporting its potential as a source of multi-target agents for Alzheimer's disease.
This study presents a synergistic dual-scaffold catalyst featuring nitrogen-doped carbon networks and graphene-templated SBA-15 that effectively prevents cobalt nanoparticle sintering, achieving high-efficiency and ultra-stable ammonia decomposition through optimized metal-support interactions and electronic modulation.
This study demonstrates that optimized micro-laser-induced breakdown spectroscopy (Micro-LIBS) serves as a reliable, near-non-destructive tool for precisely identifying pigments and mapping layer thicknesses in ancient Dunhuang murals, successfully reconstructing the painting sequence of a detached fragment with high spatial resolution.
This study demonstrates that while the methanolic extract of *Bergera koenii* leaves exhibits superior antioxidant activity, the green-synthesized zinc oxide nanoparticles derived from the same plant possess enhanced antibacterial efficacy against *E. coli* and *S. aureus*, highlighting their distinct potential for pharmaceutical and biomedical applications.
This study demonstrates that dehydrated *Saccharomyces cerevisiae* granules act as a physical buffer in citric acid-sodium bicarbonate systems by undergoing rapid capillary hydration and structural softening, which significantly delays hydronium ion diffusion and gas evolution compared to pure mineral effervescent reactions.
