Photochemical Synthesis of Vitamin B1: [By Cable]

Vitamin B1

Vitamin B1 is a watersoluble vitamin. It consists out of a pyrimidineand a thiazol ring, which are synthesized independently and linked afterwards.Vitamin B1 is de novo produced by many plants and microorganisms. Humans and animals have to take it up by nutrition. They are only able to do the phosphorylation reaction of the thiamin molecule. Thiamin is found free and as mono-, diand triphosphat...

Cxxix. Synthesis of Vitamin B1 by Intestinal Bacteria of the Rat

MANY types of micro-organisms have been tested by various workers for their ability to synthesize "vitamin B" (=complex). In such studies the organisms were grown in various nutrient media and the " vitamin B " was detected by its growth-promoting action or by curative tests on experimental animals such as the rat, the mouse or the pigeon. Thus "vitamin B " has been reported to have been produc...

Synthesis and characterization of transition metal doped ZnSe/ZnS nanocrystals by a rapid photochemical method

In the present work, a one pot, rapid and room temperature photochemical Synthesis of transition metal (TM; Cu, Mn, Cr)-doped ZnSe/ZnS core/shell nanocrystals (NCs) was reported. FT-IR spectrum confirmed the capping of ZnSe by thioglycolic acid. XRD and TEM analysis demonstrated zinc blende phase NCs with an average size of around 3 and 5 nm for TM:ZnSe and TM:ZnSe/ZnS NCs, respectively. PL spe...
