In winemaking, large amounts of grape skin (GS) are generated as by-products, which contain not only abundant degradable cellulose, hemicellulose, and pectin but various functional polyphenols. contrast to most studies focusing on the utilization extractives, current study investigates use ultrasonicated (UGS) containing all components develop a multifunctional composite film. Owing dissociatio...

In the study of polyvinyl alcohol (PVA) alignment layers for liquid crystal devices, we found that the anchoring strength can be greatly varied by changing the alignment film thickness. Both the polar and azimuthal anchoring strengths increased with increasing film thickness; however, they had different film thickness dependences. It was also noticed that the quartic term in the expansion of th...

The effect of temperature on the fluorescence properties of l,8-diphenyl-l,3,5,7-octatetraene (DPO) in polyvinyl alcohol) film (PVA) was investigated in the range from 295 to 428 K. Upon heating above 353 K, the quantum yield of D P O increases rapidly. This effect is irreversible, similarly as the optical density in the long wavelength absorption band (320-440 nm). It has its origin in the cis...

Abstract Questions and potential misperceptions have arisen about the contribution of liquid detergent capsules to environmental microplastics issue. The film these detergents is highly water soluble, also in cold water, as it must fully dissolve during every type washing process. Water-soluble grades polyvinyl alcohol, most commonly used capsule material, are recognised be biodegradable. In cu...

BACKGROUND: Biotechnology applications of magnetic gels include biosensors, targeted drug delivery, artificial muscles and magnetic buckles. These gels are produced by incorporating magnetic materials in the polymer composites. METHODS: A biocompatible magnetic gel film has been synthesized using polyvinyl alcohol. The magnetic gel was dried to generate a biocompatible magnetic film. Nanosized ...
