Degradation of Petroleum Hydrocarbons in Wastewater by MnFe2O4@BC Catalysts Activated with Persulfate: Investigation into Radical and Non-radical Transformation Pathways and Mechanisms

This study demonstrates that MnFe2O4-supported biochar catalysts, synthesized via sol-gel method with a 4:1 Fe:Mn ratio, efficiently degrade petroleum hydrocarbons in wastewater through a synergistic persulfate activation system involving both radical (SO4•−, •OH, O2•−) and non-radical (1O2) pathways, achieving removal rates of up to 88.05% within 24 hours.

Magnetic and Electrochemical Dynamics in Thermal Annealed Mg0.5Mn0.5Fe2O4

This study demonstrates that thermal annealing of Mg0.5Mn0.5Fe2O4 nano spinel ferrites creates a functional trade-off where higher temperatures (900 °C) optimize magnetic softness by increasing crystallite size and reducing surface disorder, while lower temperatures (600–700 °C) preserve the porous surface area necessary for superior electrochemical charge storage.

DFT-based prediction of anti-cancer activity of some organo-Pt IV complexes

This study employs Density Functional Theory (DFT) to predict the anti-cancer activity of twenty-three Pt(IV) and four Pt(II) complexes against HCT116 and A2780 cell lines by analyzing their thermodynamic transformation into active Pt(II) species and pharmacokinetic properties, demonstrating that these computational models can reliably forecast the efficacy of novel drugs prior to synthesis.

Observation of Protonation-Assisted Contrary Aggregate Emission with Strong and Weak Electron Donor Substituents in Barbituric Acid-Pyran Conjugate Triads

This study reports the design and synthesis of two barbituric acid-pyran conjugate triads that exhibit aggregation-induced emission enhancement and demonstrate contrasting, protonation-responsive fluorescence behaviors in the solid state—blue-shifted enhancement for the phenyl-substituted derivative and red-shifted quenching for the anisyl-substituted derivative—driven by differences in donor strength and conjugation effects.
