Summary: This study investigates the effect of nano-ceria and nano-zirconia particles on the weather resistance property of polyurethane coatings. The results show that both nano-ceria and nano-zirconia have the potential to enhance the weather resistance performance of PU-coated fabrics, and the weather resistance improves gradually with increasing nanoparticle concentration. Nano-ceria has a better effect on improving weather resistance compared to nano-zirconia, especially at higher concentrations.

Summary: This paper presents a theoretical investigation on a new actuator design using anisotropic colloidal particles grafted with stimuli-responsive polymer chains. These artificial muscles combine the osmotic actuation principle of hydrogels with the structural alignment of colloidal liquid crystals for directional motion. The study identifies the solubility, degree of polymerization, salt concentration, and grafting density of the polymer chains as important factors for actuator performance and tunability. Computational results suggest that the proposed material matches or exceeds the performances of natural muscles, providing guidelines for the realization of artificial muscles with predefined actuation properties.

Summary: An amorphous 3D-Ti(IV)-(syn-anti)-(Me, Me)-Bimane polymeric MOFs were successfully synthesized for the first time by fast assembling syn and anti isomers of (Me, Me)bimane under microwave assisted hydrothermal procedures. The mixed ligands of (syn-anti-(Me, Me) bimane) isomers were expected to form crystalline Ti-MOFs but instead produced an amorphous Ti(IV)-MOFs, with a high specific surface area of approximately 689 m(2)/g as characterized by various techniques like XPS, TEM, and BET analysis.

Summary: This study aimed to synthesize BaTiO3 nanocrystalline particles using the tartrate precursor process, and then prepare nanocomposite films with PVA. Analysis using XRD and FTIR showed complex interactions between BaTiO3 nanoparticles and the PVA matrix. As the concentration of BaTiO3 nanoparticles in the PVA matrix increased, the optical band gap decreased while the Urbach energy increased.

Summary: This study outlines the fabrication and characterization of pamidronate (PDS) embedded nanofibrous scaffolds based on polycaprolactone/polycaprolactone-polyethyleneglycol-polycaprolactone (PCL/CEC) blends for osteoporotic bone defect management. The electrospinning technique was utilized to fabricate PDS-loaded scaffolds, and the effect of PDS on the blends was evaluated in terms of surface morphology, wettability, biodegradability, and in vitro cytocompatibility. The results showed that the PCL/CEC-PDS scaffolds had a fibroporous architecture, appropriate mechanical properties, and the ability to support cell growth, indicating their potential for managing osteoporotic bone defects.
