The synthesis of keratin proteins during development of the embryonic chick feather was studied by quantitative gel electrophoresis of the reduced and carboxymethylated proteins. The results demonstrated a coordinated synthesis of the major keratin proteins, during and after the onset of keratin synthesis. The results from gel electrophoresis correlated well with electron microscope visualizati...
tio2 nanorods can be used as dye-sensitized solar cells and as various sensors and photocatalysts. these nanorods are synthesized by a using thermal corrosion process in a naoh solution at 200 oc with tio2 powder as a source material. in the present work, the synthesis of tio2 nanorods in anatase, rutile and ti8o15 phases and the synthesis of tio2 nanorods by using the sol-gel method and alkali...
in this thesis, a better reaction conditions for the synthesis of spirobarbiturates catalyzed by task-specific ionic liquid (2-hydroxy-n-(2-hydroxyethyl)-n,n-dimethylethanaminium formate), calcium hypochlorite ca(ocl)2 or n-bromosuccinimide (nbs) in the presence of water at room temperature by ultrasonic technique is provided. the design and synthesis of spirocycles is a challenging task becaus...
Highly dispersed Co particles in MCM-41 were prepared by direct addition of CoCIz to the synthesis gel. The small clusters of Co did not sinter during reduction and sulfidation. Incorporation of Co into the MCM-41 lattice was not observed. The addition of Co to the synthesis gel did not alter the structural characteristics of the MCM-41 samples.

Titanium silicate-2 (TS-2) is synthesized in the presence of different amounts of methylamine. The as-synthesized samples were characterized using IR, DRS UV and SEM techniques. The effect of hydrogen fluoride and methylamine on the synthesis is studied. Results showed that the TS-2 crystallinity and titanium content in the framework increase with addition of both hydrogen fluoride and methylam...
