This paper deals with methods to predict residue (heel) in a tank after drainage of polymer gels from the tank. Gels of various rheological properties were considered in which a thixotrope (Xanthan gum) and a thickener (carboxymethyl cellulose) were

The properties of heteroaggregates (aggregates of particles that are different in various aspects such as size, surface charge) depend on the properties of the particles along with the initial relative concentration of the particles. In this article,

β-Carotene was used as a probe to investigate the protection offered by 2-ethylhexyl 4-methoxycinnamate, a photostabilizer, upon ultraviolet-A photodegradation. β-Carotene and 2-ethylhexyl 4-methoxycinnamate were arranged in two distinct macroscopi

Natural dyes are normally unstable to photooxidation by UV light. We have measured the stability of a number of natural dyes in combination with high concentrations of antioxidants, excited state quenchers, and UV absorbers. We find that certain comb
