This review article considers the role of fatty acids and the mutual association of their long-chain (e.g. C18) alkyl and alkenyl groups in some important aspects of papermaking. In particular, published findings suggest that interactions involving fatty acids present as condensed monolayer films can play a controlling role in pitch deposition problems. Self-association among the tails of fatty acids and their soaps also helps to explain some puzzling aspects of hydrophobic sizing of paper. When fatty acids and their soaps are present as monolayers in papermaking systems, the pH values associated with their dissociation, i.e. their pKa values, tend to be strongly shifted. Mutual association also appears to favor non-equilibrium multilayer structures that are tacky and insoluble, possibly serving as a nucleus for deposition of wood extractives, such, as resins and triglyceride fats, in pulp and paper systems.

Interfacial Assembly

Water/toluene interfacial self-assembly of nanostructures is a powerful bottom-up approach for film fabrication because of the low cost and high efficiency, and it is a simple and universal method for almost all low-dimensional nanostructures. The method involved adding alcohol and then toluene (here the dispersant was itself alcohol, only toluene was added) into SiO2 nanoparticle dispersion, and then a large quantity of distilled water was rapidly poured into the mixed system. Simultaneously, nanoparticles in the dispersion were extracted to the water/toluene interface, forming a thin film with a nearly perfect hexagonal close packed phase. Large-area nanoparticle monolayer films (e.g., more than 20 cm2) could be prepared in less than 1 min. The close-packed structures of these thin films were verified by a field emission scanning electron microscopy (FESEM, Hitachi S-4800, Japan). We also investigated the whole process of forming the films and found out the mechanism of water-induced interfacial assembly. As for the specific kinetic mechanism of the fabrication process, it is expected to further study in later time.

Allium Schoenoprasum

Abstract Background: Allium schoenoprasum is a world-wide common vegetable while only its leave is used in the food factory. Its stalk is largely discarded, for potential heavy metal accumulations, which eventually lead to an environmental contamination. To fully utilize this vegetable and minimize its metal content, the major polysaccharide content is purified and characterized with chemical and computational approaches.Results: The major polysaccharide component from the stalk of Allium schoenoprasum (AssP) was extracted and purified. The gel filtration chromatography purified AssP exhibited a molecular weight of around 1.6 kDa, which was verified by MALDI-ToF-MS. Monosaccharide analysis revealed its composition as rhamnose: arabinose: galactose: glucose: mannose: fructose with a molar ratio of 0.0264:2.46:3.71:3.35:1.00:9.93, respectively. Multiple NMR analysis revealed its backbone as α-Ara/Glu/Gal-(1→2)-linked and β-D-Fru-(4→5)-linked sugar residues. There was no tertiary structure of this polysaccharide, however, it self-assembled into a homogenous nanoparticle with a diameter of ~600 nm. The solution behavior of this AssP polysaccharide was simulated, and there was no specific binding site on one molecule for another. Association of this polysaccharide was concentration dependent. As the AssP concentration increased, the spherical particles increased their sizes and eventually merged into cylindrical micelles. The diversity of AssP hydrodynamic behavior endowed potential versatility in its applications.Conclusions: AssP was characterized as a polysaccharide with identified monosaccharide compositions and linkage between them. Although there is no tertiary structure in one AssP molecule, self-assembly of AssP molecules could form nanoparticles or micelles depending on its solution concentrations. The unique AssP solution behavior endows itself a potential biomaterial for nanoparticles preparations.
