Four new D-glucose derived m-s-m type gemini surfactants with variable spacer and tail length have been synthesized by a simple and efficient synthetic methodology utilizing the free C-3 hydroxy group of diisopropylidene glucose. The synthetic route to these gemini surfactants with a quaternary ammonium group as polar head group involves a sequence of(More)
With increasing gap in the demand and supply of vital organs for transplantation there is a pressing need to bridge the gap with substitutes. One way to make substitutes is by tissue engineering which involves combining several types of synthetic or biomaterials, cells and growth factors cross-linked together to synthesize a functional scaffold for repair(More)
Seed germination and seedling growth as well as chlorophyll and carotenoid contents of mustard and gram seeds were inhibited or reduced significantly due to the treatment of different concentrations (100, 250, 500, 1000 and 2000 ng/ml) of aflatoxin B1. The range of inhibition in all the parameters was found to be directly influenced by the concentrations of(More)
