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.

When you mix sugar with water, the sugar dissolves to make a transparent solution. Salt dissolves in water too. Heat can help some substances dissolve faster in water. Salt, for example, will dissolve quicker in hot water than in cold water. Substances that dissolve in water are called soluble substances.Substances that do not dissolve in water are called insoluble substances. When you mix sand or flour with water, they do not dissolve.1  Page: 2  1. 3  2. 4  3. 5  4.6  5.ubstances that dissolve in water are called soluble substances.
