Synthesis and characterization of epoxy polymers containing azobenzene groups that exhibit optical birefringence
(2007-12-03)
A push–pull azo dye (DO3) was used as photosensitive substance to satisfactorily synthesize new epoxy polymers containing azo groups covalently linked. Three different amines BA, TA and MXDA were used as hardeners. Materials ...
Jejunal microvilli atrophy and reduced nutrient transport in rats with advanced liver cirrhosis: improvement by Insulin-like Growth Factor I
(BioMed Central, 2004-06-14)
