The effects of pH, ionic strength and polymer ratio in the complexation of chitosan (CHI) with different anionic polysaccharides, namely gum Arabic (GA), sodium alginate (ALG) and κ-carrageenan (CRG), were investigated. This was made using titration techniques, which allowed the determination of stoichiometry and binding constant of complexes.

The hydration of calcium aluminate cement (CAC) in the presence of sodium alginate which is known to slightly retard Portland cement, was studied using heat flow calorimetry and mortar strength testing. Most surprisingly, addition of alginate resulted in an earlier occurrence of the maximal heat release as well as an increased early strength, thus confirming that in CAC alginate acts as accelerator.

This work investigated the effect of adding low concentrations of nano-SiO2 (0.5, 1.0 and 1.5%) in the properties of films based on sodium alginate, to identify lower thresholds in the proportion of the reinforcing agent. It was found that, even in the smallest proportion, thermal stability of the nanocomposites improved significantly (with degradation onset increased by almost 15% compared with the control film).

This study investigated the impact of heterogeneity of crosslinking on a range of physical and mechanical properties of calcium alginate networks formed via external gelation with 0.25–2% sodium alginate and 2.5 and 5% CaCl2. Crosslinking in films with 1–2% alginate was highly heterogeneous, as indicated by their lower calcium content (35–7 mg Ca⋅g alginate− 1 ) and apparent solubility (5–6%).

Enzymes are thermo-labile and they may lose activity during pelletization of feed. Encapsulation/ coating of enzyme is important for the stability of feed enzymes. Effect of feeding encapsulated amylase enzyme in corn soy pelleted diets on the performance of broilers was studied. Amylase enzyme were encapsulated with sodium alginate and included in diets at 2000 IU/kg.

The optimal composition of ferrous sulphate, L-ascorbic acid, Lactobacillus acidophilus and sodium alginate for encapsulation was studied. The Central Composite Rotatable Design- Response Surface Methodology (CCRD-RSM) was used to determine the optimum proportion of the matrices for higher yield of encapsulation (%) and strength of beads (g). Results showed that the entrapped viable cells and strength of the beads, increased by optimizing ingredients.

Numerical simulation of blood flow with sodium alginate nano particles in stenosed human arteries in the presence of body acceleration is obtained. Effect of sodium alginate (SA) nano particles in the presence of body acceleration is observed on velocity, flow rate and resistive impedance to blood flow in stenosed human artery. The governing equations are discretized by explicit finite difference scheme. The discretized equations are the simulated using MATLAB.
