The spectral, structral and thermal characterizations of dimethyl sulphoxide, pyridine, ethanolamine and N-methyl formamide intercalated kaolinites
(Verlag der Zeitschrift fur Naturforschung, 2010)
The intercalation of dimethyl sulphoxide (DMSO), pyridine (Py), ethanolamine (Ea), and Nmethyl formamide (NMF) molecules into the kaolinite interlayers led to an appreciable decrease of 3697 cm-1 of the hydroxyl band. The ...
Volatile constituents and antimicrobial activities from flower and fruit of arbutus unedo L.
(2010)
Essential oils isolated by hydrodistillation from flower and fruit of Arbutus unedo growing in Turkey were analyzed by GC and GC/MS. Forty-nine compounds, representing around 95% of the total oils were identified. ...
