“…However, for the nondissociating macromolecules, adsorption of these molecules on the particle surface was suggested as the viscosity reduction mechanism. The adsorption of monosaccharides on the alumina surface was also reported by Singh and Mohan . Falkowski et al showed that neither shift in the isoelectric point nor significant change in zeta potential of alumina is observed with the addition of fructose, glucose and their derivatives with carboxylic group attachments.…”

Control of the rheological properties of the nanoparticle suspensions is challenging. In this study influence of the solids content and the fructose addition on the viscosity of nano alumina suspensions have been investigated by low temperature differential scanning calorimetry (LT‐DSC), rheometry, and zeta potential measurements. Analysis of the water melting events in LT‐DSC revealed useful information for explaining the rheological behavior of the nanoparticle suspensions. It was shown that the bound water layer has a negligible effect on the viscosity of micrometer‐size particle suspension while it increases the effective solid content of alumina nanoparticle suspensions significantly leading to high viscosities. The presence of fructose modifies the bound water layer, decreases the effective solids content, hence resulting in viscosity reduction. Fructose addition lowers the pH of the suspension, but has a negligible effect on the zeta potential. The origin of the bound water, and electrostatic and steric effects of the fructose addition on the viscosity are discussed.

“…Both can take place at the same time, but when the antigen and aluminum salts carry the same type of charge (repulsive to each other), ligand exchange plays a key role [41,42]. Other mechanism of adsorption was also proposed, including hydrophobic interactions [41], and other non-charge-associated surface interactions such as monosaccharides on the surface of aluminum oxide at PZC (pH 9.0) [43]. All of these mechanisms of adsorption may co-exist for a single antigen [28].…”

“…Glucose, galactosamine, fructose, rhamnose, arabinose, fucose, glucosamine, galactose, xylose, mannose, ribose, mannosamine, muramic, galacturonic, and glucuronic acids have all been identified in soil [15, 28, 90–96]. Tian et al [60] reported ca.…”

“…Adsorption of carbohydrates, such as glucose or fructose, on alumina interfaces is characterised by an adsorption isotherm of a typical L-type, and an adsorption mechanism based on dipolar interaction has been suggested [90]. The adsorption was pH dependent and was affected by anions (Cl − , SO 4 2− , and PO 4 3− ) and cations; fructose appeared to be better adsorbed than glucose.…”

Organic acids, vitamins, and carbohydrates represent important organic compounds in soil. Aliphatic, cyclic, and aromatic organic acids play important roles in rhizosphere ecology, pedogenesis, food-web interactions, and decontamination of sites polluted by heavy metals and organic pollutants. Carbohydrates in soils can be used to estimate changes of soil organic matter due to management practices, whereas vitamins may play an important role in soil biological and biochemical processes. The aim of this work is to review current knowledge on aliphatic, cyclic, and aromatic organic acids, vitamins, and carbohydrates in soil and to identify directions for future research. Assessments of organic acids (aliphatic, cyclic, and aromatic) and carbohydrates, including their behaviour, have been reported in many works. However, knowledge on the occurrence and behaviour of D-enantiomers of organic acids, which may be abundant in soil, is currently lacking. Also, identification of the impact and mechanisms of environmental factors, such as soil water content, on carbohydrate status within soil organic matter remains to be determined. Finally, the occurrence of vitamins in soil and their role in biological and biochemical soil processes represent an important direction for future research.
