Summary: As the most abundant renewable aromatic polymer on the planet, lignin is gaining growing interest in replacing petroleum-based chemicals and products. However, only <5% of industrial lignin waste is revalorized in its macromolecular form as additives, stabilizing agents or dispersant and surfactants. In this study, an environmentally-friendly continuous sonochemical nanotransformation process was implemented to obtain highly concentrated lignin nanoparticles (LigNPs) dispersions for added-value material applications.

Summary: The general objective of this research was to investigate the impact of initial concentration of reactants and ultrasonic irradiation power on the nanostructure of copper (II) coordination polymer. The study found that reducing the concentration of reactants and increasing the power of ultrasound irradiation can result in the formation of nanoparticles with uniform morphology and reduced particle size. Thermogravimetric and differential thermal analyses were used to determine the thermal stability of the nanoparticles. Additionally, the research successfully synthesized CuO nanoparticles through thermal decomposition.

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.

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.
