Synthesis of Hydroxyapatite by Using Calcium Carbonate and Phosphoric Acid in Various Water-Ethanol Solvent Systems
(Versita, 2009)
The purpose of the present study is to synthesize hydroxyapatite by using CaCO(3) and H(3)PO(4) in various water-ethanol solvent systems. It was observed from experiments that formation of ammonium phosphate compounds ...
Thermal Decomposition Of Allantoin As Probed By Matrix Isolation Ftir Spectroscopy
(Pergamon-Elsevier Science Ltd, 2009)
The optimized geometries, energies of the possible conformers of allantoin (2,5-dioxo-4-imidazolidinyl urea, the diureide of glyoxylic acid) as well as the barriers for conformational interconversion have been calculated ...
Flavonoid, Phenylethanoid And Iridoid Glycosides From Globularia Aphyllanthes
(Walter De Gruyter Gmbh, 2009)
A new flavone glycoside, 6-hydroxyluteolin 7-O-[6 '''-benzoyl-beta-D-glucopyranosyl-(1 -> 2)]-beta-D-glucopyranoside (aphyllanthoside, 1) was isolated from the MeOH extract of the aerial parts of Globularia aphyllanthes. ...
