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.

Do note that solubility of ionic compounds are not absolute. In fact, solubility in water is often given as a value in g/L of water. However, generally, we define solubility as: 1  Soluble substances can form a 0.1M solution at 25 Â°C. 2  Insoluble substances cannot form a 0.1M solution at 25 Â°C.t's just not as immediate as dissolution of the more soluble ionic compounds. You are probably familiar with this phenomenon: This forms because calcium carbonate dissolves. The rock is limestone, which is usually composed of pure calcium carbonate.
