This study demonstrates that incorporating a 15% mixture of wastepaper ash and waste ceramic powder as a supplementary cementitious material significantly enhances the mechanical, durability, and microstructural properties of cement mortar, offering a viable and sustainable solution for partial cement replacement.
This study presents a smartphone-assisted colorimetric platform for detecting mercury ions using a Mn-Au hybrid nanozyme whose oxidase-mimicking activity is reversibly controlled by an aptamer that desorbs upon specific Hg²⁺ binding, enabling sensitive and on-site environmental monitoring.
This paper proposes a general phenomenological framework demonstrating that geometric order, quantified by a new surface uniformity parameter, acts as an independent control variable that allows prebiotic systems to maintain useful chiral symmetry breaking despite substantial microscopic disorder, with gradual rather than threshold-like tolerance confirmed through modeling and falsifiable experimental predictions.
This study demonstrates that Fourier transform infrared (FTIR) spectroscopy coupled with machine learning outperforms near-infrared and fluorescence techniques in detecting synthetic acetic acid adulteration in white rice vinegar, while highlighting the critical necessity of tailoring chemometric models to specific vinegar brands due to significant variability in optimal preprocessing and feature selection strategies.
This study presents a low-cost, accessible TLC-UV/Vis spectrophotometric method for screening the total content and relative proportions of branched-chain amino acids in dietary supplements, offering a viable alternative for routine quality control despite its inability to fully replace reference chromatographic techniques.
This study demonstrates that Pt,Ru-codoped In₂S₃/Ta₂O₅ heterostructured films, optimized with 75 wt.% In₂S₃ and fabricated via hydrothermal and doctor blading methods, achieve 92.0% visible-light degradation of Rhodamine B within 120 minutes by leveraging narrow bandgap absorption, oxygen vacancies, and strong electronic interactions to enhance charge separation and superoxide radical generation.
This study demonstrates that microwave drying at 300W yields lemon verbena essential oil with the highest concentration of secondary metabolites and diverse bioactive compounds, while oven drying at 30°C produces the strongest antimicrobial activity against *Streptococcus pyogenes*, highlighting the significant influence of drying techniques on the oil's chemical profile and pharmaceutical potential.
This study presents a surrogate-free inverse-design workflow combining recurrent-neural-network-guided Monte Carlo Tree Search with in-loop GFN2-xTB scoring to successfully generate a library of polyimide constitutional repeating units that simultaneously achieve deep ionization potentials and large electron affinities, overcoming the typical trade-off between these properties.
This paper reports the synthesis of a gel polymer electrolyte with a tetra-branched network structure via a thiol-yne click reaction, demonstrating that its ionic conductivity is influenced by polymer content and PEG chain length, which facilitates lithium cation transport along the polymer chains in addition to the electrolyte solution.
This study reports a MOF-derived prismatic rod-like CoP electrode (CoP/NF) that exhibits exceptional hydrogen evolution reaction performance and long-term stability through synergistic electronic modulation, a conductive carbon matrix, and a nanoarchitecture rich in active sites.
