Photolytic hydration of cyanamides

Photolytic mechanism of riboflavin.

One of the most characteristic properties of riboflavin (I) is its extraordinary photosensitivity. Therefore, many investigations (1-11) have been carried out on the photolytic reaction of riboflavin and related compounds. According to Karrer et al. (2) and Kuhn et al. (3), the type of decomposition by light is dependent on the pH of the solution. When irradiated in neutral or acidic solution, ...

Photolytic depolymerization of alginate.

A photochemical reaction has been developed for the partial de-polymerization of sodium alginate, a polysaccharide utilized in medicine, pharmacy, basic sciences and foods. An aqueous solution of sodium alginate was photochemically depolymerized to approximately 40% of its average molecular weight using ultraviolet light in the presence of titanium dioxide catalyst at pH 7 over a period of 3h. ...

Heterogeneous Photolytic Synthesis of Nanoparticles

Photolytic preparation of tellurium nanorods.

Well-defined tellurium nanorods have been prepared by the photolysis of (t)Bu2Te2 in an aqueous micellar system incorporating dodecanethiol as an auxiliary morphology-directing agent.

Hydration, hydration, hydration.

Throughout the world, large numbers of manual workers perform physically demanding labour in conditions of high environmental heat stress. Although the importance of adequate hydration in combating heat stress is universally recognized, studies in a range of worker groups have demonstrated a disturbingly poor hydration level in a high proportion of at-risk workers. Management of work in hot env...
