Summary: This study presents experimental evidence that specific molecular weights of poly(vinyl alcohol) (PVA) are necessary to enhance the freeze-thaw resistance of portland cement paste. The enhancement is achieved through the interaction between biomimetic polymers like PVA and ice, rather than improved hydrophobicity or an adequately entrained air void system.

Summary: Self-healing proton-exchange membranes (PEMs) made of poly(vinyl alcohol) (PVA) and Nafion were synthesized using the freeze-thaw method. The blend membrane successfully reduced methanol permeability and improved selectivity compared to the recast Nafion membrane due to the selective nature of PVA towards water. The addition of PVA promoted hydrogen bond formation and enabled the Nafion-PVA membrane to undergo a self-healing process, recovering its methanol barrier function.

Summary: Phytic acid-assisted PANi/PVA hydrogel with self-reinforcing features is developed, showing enhanced mechanical performance. Phytic acid plays a crucial role in salinizing aniline and forming hydrogen bonds with PVA, resulting in conductive PANi and structure orientation. The hydrogel exhibits improved fracture strength, Young’s modulus, and toughness after repetitive stretching, attributed to the anisotropic structures fixed by hydrogen bonds. The PVA/PA/PANi hydrogel shows good mechanical durability and reusability, making it a reliable strain sensor.

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.
