Summary: The content of hard segments and the degree of cross-linking have an effect on the mechanical properties of waterborne self-healing polyurethane, while tensile strength and self-healing conditions also influence the self-healing properties. Increasing the content of hard segments/cross-linking agent improves tensile strength but reduces the self-healing performance. The self-healing ability is attributed to the dynamic exchange of disulfide bonds and the thermal reversibility of hydrogen bonds in the system.

Summary: Sustainable self-healing polyurethanes have been developed using bile acid units and oligo(ethylene glycol)s as hard and soft segments, respectively. These polyurethanes exhibit similar mechanical performance to soft tissues and achieve a high self-healing efficiency of 90% in tensile strength. Multiple hydrogen bonds from bile acid hydroxyl groups and urethane bonds contribute to the self-healing ability, making them the first reported elastomers with quadruple hydrogen bonds from sustainable molecules. With their desirable biocompatibility in vitro and in vivo, these metal-free self-healing polyurethane elastomers are expected to find practical applications in soft tissue repair.

Summary: This study focuses on manganese doped CdS thin films synthesized by chemical bath deposition. The incorporation of Mn2+ cations in CdS was found to influence the crystalline structure, morphology, and optoelectronic properties. Doped thin films exhibited a uniform hexagonal structure, changed growth orientation, and showed scale-like and needle-like morphologies. The bandgap and rectification speed of Schottky diodes were modified by introducing manganese. This study suggests the potential for affordable high-speed optoelectronic devices.
