Effect of substituents on the 13 C chemical shifts of the azomethine carbon atom of N-(phenyl substituted) pyridine-4-aldimines
(Elsevier, 1999)
13 C chemical shifts of the azomethine carbon atom for N-(substituted phenyl)pyridine-4-aldimines, 4-Py-CH=N-C 6 H 4 -X, X having a wide range of substituent effects, have been determined in CDCl 3 solution. Exceptionally ...
Chemical composition of the essential oil of micromeria albanica (Griseb. ex K. Maly) Silic
(Taylor & Francis, 1999)
The composition of the essential oil of the Balkan peninsula endemic plant Micromeria albanica (Griseb. ex. K. Maly) Silic was analyzed for the first time by GC and GC/MS. The oil, which was present in 0.9% (v/w) yield, ...
Real surface area of the aluminium electrode in sodium chloride solution / Stvarna površina eletrode od aluminijuma u rastvoru natrijum-hlorida
(Belgrade : Serbian Chemical Society, 1999)
By combining the techniques of electrochemical slow potentiodynamic, AC impedance and atomic force microscopy (AFM), it was shown that the differences in the anodic dissolution rates of Al in 0.5 NaCl solutions as measured ...
Corrosion rates and negative difference effects for Al and some Al alloys
(Springer, 1999)
The rotating disc-ring technique with a Pt ring was used to quantitatively detect hydrogen evolved on an Al-disc electrode during spontaneous corrosion at open-circuit potential or during anodic polarization of an Al disc ...
