By the early 1990s, the PCR technique with Taq polymerase was being used in many areas, including basic molecular biology research, clinical testing, and forensics. It also began to find a pressing application in direct detection of the HIV in AIDS.
Abstract. The solubility of fructose in waterâethanol and waterâmethanol mixtures and the saturated density of each solution at 20, 30, and 40 Â°C over a range of water mass percentage have been measured.Also, a new modification of the Wilson model has been proposed to describe solubility data satisfactorily.bstract.

The hydrocarbon tail attached to its vanillin foundation ring doesn't lower the solubility of zingerone much because it contains a carbonyl group (C=O) that can form strong hydrogen bonds with water molecules. Zingerone is sparingly soluble in water, but also freely soluble in fats and oils.he oxygen-containing groups attached to the ring in vanillin can form strong hydrogen bonds with water, making it water soluble (about a gram of vanillin can be dissolved in 100 mL of cold water).
