Summary: This study explores the effects of chalcogen bonding interactions, particularly N-oxidation, on the properties of bithiazole-containing materials. It shows that N-oxidation can impact the electronic band gap by altering HOMO and LUMO levels, and the intramolecular S-O chalcogen bonding in bithiazole contributes to rigidifying the conjugated system. Computational analysis reveals that the N-oxide chalcogen bonding interaction is significantly stronger than other common chalcogen bonding interactions in conjugated materials.

Summary: The composite Fenton nanocatalyst was prepared by integrating Fe3O4 nanoparticles within a self-assembled 3D reduced graphene oxide aerogel in a water-based process. This hybrid showed efficient degradation of Acid Green 25 organic dye in aqueous solution with the presence of H2O2, with pH adjustment found to enhance electrostatic interactions between the dye and the 3D structure. The high performance was attributed to the charge-transfer complex formation between rGO and Fe3O4 nanoparticles, facilitated by the in situ synthesis procedure.

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.
