Saccharin (o-sulfobenzimide; 1,2-benzothiazole-3(2H)-one 1,1 dioxide; Hsac, Figure 1) is one of the best known and most widely used artificial sweetening agents. Initially, investigation of the interaction of saccharin with different biologically relevant cations attracted great interest due to the suspected carcinogenicity of this compound which, notwithstanding, was recently definitively rule...

Xylitol is a polyalcohol of five carbon atoms which is widely used in the food and chemical industry. Its interest is due to the sweetening power similar to that of sucrose. However, it has been shown that the use of xylitol as a sweetener is better due to its anticariogenecity, tooth rehardening and remineralization properties. It is suitable as sugar substitute for diabetics, and it limits th...

• Selective removal of H 2 S and CO is essential in natural gas sweetening. Four azole based protic ionic liquids were studied. Density functional theory molecular dynamics simulations performed to understand absorption phenomenon. binds the nitrogen anion form a C-N bond, whereas generates an HS - anion. MD results indicate that [1,2,4-triaz] better compared [1,2,3-triaz] To achieve efficient ...

low caloric sweeteners have been investigated to substitute sugar as an advantage for both nutritional and medicinal purpose. these sugar substitutes are interesting particularly for concepts marketed under a natural claim. among these, stevia rebaudiana is a small shrub; its leaves are used as a sweetener. serial dilution of the hot water crude extract of s. rebaudiana leaves and aqueous solut...

A new approach to the computation of long integers cube third power computation based on a splitting in two divide et impera approach and on a modified Toom-Cook unbalanced method is presented. A detailed description of its practical implementation by using the GMP library and performance comparison are also described. AMS Subject Classification: 11A05, 11A25, 11K65, 11Y70
