AI Article Synopsis
Article Abstract
Little information exists on the effects of ensiling on condensed tannins or proanthocyanidins. The acetone-butanol-HCl assay is suitable for measuring proanthocyanidin contents in a wide range of samples, silages included, but provides limited information on proanthocyanidin composition, which is of interest for deciphering the relationships between tannins and their bioactivities in terms of animal nutrition or health. Degradation with benzyl mercaptan (thiolysis) provides information on proanthocyanidin composition, but proanthocyanidins in several sainfoin silages have proved resistant to thiolysis. We now report that a pretreatment step with sodium hydroxide prior to thiolysis was needed to enable their analysis. This alkaline treatment increased their extractability from ensiled sainfoin and facilitated especially the release of larger proanthocyanidins. Ensiling reduced assayable proanthocyanidins by 29%, but the composition of the remaining proanthocyanidins in silage resembled that of the fresh plants.

Applying cellulose paper on the triboelectric material is the trend of developing eco-friendly triboelectric nanogenerator (TENG). However, the researchers always pay attention to improve the triboelectric property of cellulose paper by the grafting of functional groups and the introduction of conductive or high dielectric property materials, while neglecting the effects of lignocellulose fiber composition including hemicellulose and lignin. In this work, the contents of hemicellulose and lignin were adjusted by sodium hydroxide and sodium chlorite, respectively; and the effects of hemicellulose and lignin on the triboelectric performance of cellulose paper were evaluated.

In alkali/surfactant/polymer (ASP) flooding systems, alkalis react with clay minerals such as Illite, montmorillonite, and kaolinite, leading to reservoir damage and impacting oil recovery rates. Therefore, studying the dissolution effects of strong alkalis on clay minerals is crucial for improving oil recovery. This study uses Illite as a representative clay mineral and employs the ReaxFF reactive force field and molecular dynamics simulations to model its dissolution in NaOH solution.

Chitin hydrogel and hydrogel-based products are some of the frequently reported biomaterials for biomedical applications. Yet there is a void in understanding chitin's dissolution mechanism and its most suitable solvent system(s). Chitin is a natural polysaccharide polymer which can be dissolved in solvents such as calcium chloride- methanol, sodium hydroxide/urea (NaOH/urea), lithium chloride diacetamide (LiCl/DMAc), ionic liquids and deep eutectic solvents.
