Summary: Photocatalysis using Co-ZnO as a catalyst showed superior efficiency in degrading organic pollutants in wastewater, particularly methyl orange dye. The inclusion of 10% cobalt in Co-ZnO significantly enhanced its photocatalytic activity, leading to faster degradation compared to pure ZnO. The presence of cobalt inhibited electron-hole recombination, contributing to the improved degradation of the dye.

Summary: In this study, g-C3N4 sheets supported with Fe-doped ZrO2 nanoparticles were prepared as photocatalysts for the efficient photodegradation of methyl orange and tetracycline. The addition of Fe-doped ZrO2 nanoparticles improved the surface area and light absorption capacity of g-CN, leading to enhanced photocatalytic activity. The development of heterojunctions between g-C3N4 and Fe-doped ZrO2 nanoparticles effectively reduced the recombination rate of electron and hole pairs, resulting in improved photodegradation performance.

Summary: Material modification with low surface energy can achieve lower surface free energy on micro-and nano-rough structures, which is crucial for developing superhydrophobic surfaces. In this study, attapulgite (APT) was modified with alkylamine, alkylammonium salt, and stearic acid, and the interaction between low surface materials and attapulgite was explained. The results showed that the hydrophobicity of APT was significantly modified by the modifiers, and the surface free energy of the composites first decreased and then increased with increasing molecular number of low surface energy monomers.

Summary: The main aim of this study was to prepare a drug-drug coamorphous system to improve the physiochemical properties, solubility and stability of Apremilast and Indomethacin. Various solid-state characterization techniques were used to characterize the prepared system. Molecular level interactions were studied using molecular modeling and ATR-FTIR and 1H NMR. Solubility and dissolution studies showed the benefits of the coamorphous system. The system was found to be stable for a period of five months. Permeation study also demonstrated improved flux for both drugs compared to their crystalline forms. The coamorphous system showed anti-psoriatic and anti-melanogenic activity based on molecular docking results. Overall, the developed CAM-based supersaturated system exhibited improved physicochemical properties and physical stability.
