When hydrophobically modified chitosan (HM-CHI) comes into contact with red blood cells (RBCs), it can cause agglomeration. This property leads HM-CHI to be a potential agent to form a rapid haemostatic plug to stop bleeding at wound sites. In this study, we investigated the properties of the HM-CHI biopolymer to act as an agent that rapidly clots blood. We have examined the synthesis and structural characteristics of HM-CHI - blood substances using X-ray diffraction, infrared spectroscopy and elemental analysis...

The solubility of calcium phosphate in concentrated dairy brine streams is important in understanding mineral scaling on equipment, such as membrane modules, evaporators, and heat exchangers, and in brine pond operation. In this study, the solubility of calcium phosphate has been assessed in the presence of up to 300 g/L sodium chloride as well as lactose, organic acids, and anions at 10, 30, and 50 °C. As a neutral molecule, lactose has a marginal but still detectable effect upon calcium solubility. However, additions of sodium chloride up to 100 g/L result in a much greater increase in calcium solubility...

The microstructure and rheological properties of colloidal suspensions depend on particle size and shape. This work aims to further control the size, shape, and polydispersity of anisotropic silica colloids, to reduce particle size, and to provide additional mechanistic insights on a prevalent, water-in-oil emulsion synthesis method. Key findings show that the dimensions of anisotropic silica particles can be systematically varied by approximately fivefold, with a limiting minimum particle size (D≈60nm, L≈300nm) obtained from emulsions with excess polyvinylpyrrolidone (PVP) and sodium citrate...
