This study demonstrates that Cu and Zn doping of NiTiO₃ nanoparticles yield divergent bandgap responses due to their distinct electronic configurations, where Cu²⁺ introduces impurity states that significantly narrow the bandgap and enhance visible-light photocatalytic activity, while Zn²⁺ has a negligible effect.
This study demonstrates that MnCo2O4 spinel nanostructures anchored on multi-walled carbon nanotubes, synthesized via hydrothermal-assisted calcination, deliver exceptional pseudocapacitive performance with high specific capacitance, superior rate capability, and outstanding cycling stability, making them a promising electrode material for next-generation high-performance supercapacitors.
This study employs a multidimensional approach combining Taguchi optimization, kinetic and thermodynamic modeling, and life cycle assessment to evaluate n-Hexane, n-Heptane, and Ethanol for spent coffee grounds oil extraction, revealing n-Hexane as the most efficient solvent while identifying Ethanol as the most environmentally sustainable option for biodiesel production.
This study presents an autonomous, multi-stimuli-responsive bilayer hydrogel actuator that, when coupled with a newly developed NaOH–Sultone pH-clock, achieves programmable bidirectional mechanical motion and synchronized fluorescence modulation without external intervention.
This paper presents a programmable deconstruction–reconstruction strategy that enables the divergent skeletal editing of pyridines into structurally diverse multisubstituted benzenes through controlled single-atom and atom-pair transformations, offering a versatile platform for late-stage functionalization of pharmaceuticals and bioactive molecules.
This paper presents a comprehensive theoretical framework for analyzing sequential double-regenerative enzymatic mechanisms in protein-film voltammetry, revealing distinct electrochemical fingerprints that enable the quantitative extraction of kinetic parameters and the mechanistic interpretation of redox protein behaviors.
This study establishes a robust analytical framework for characterizing complex bauxite residue by combining closed-vessel microwave-assisted multi-acid digestion with suppressed ion chromatography and helium-collision cell ICP-MS to accurately quantify both trace rare earth elements and soluble inorganic anions while effectively managing matrix interferences and fluoride hazards.
This study successfully isolated and characterized a linoleic-linolenic acid mixture, spinasterol, and lupeol from *Strobilanthes dyeriana* leaf extract using a combination of chromatographic and spectroscopic techniques, confirming the plant's phytochemical composition.
This study demonstrates that in confined polymer–ionic liquid materials, competing ordering tendencies can be resolved through frustration-mediated structural-state selection, where the suppression of long-range order into a predominantly amorphous state (as seen in pMBA–FSI) uniquely optimizes ionic conductivity by overcoming the traditional trade-off between structural order and molecular mobility.
This study demonstrates that treating soybean hull agro-waste with sulfuric acid followed by pyrolysis at temperatures up to 800°C effectively transforms its morphology and chemical composition, yielding a value-added material with promising characteristics for use as a renewable reinforcement in sustainable composite applications.
