(1995)Deuterium quadrupole splittings from the aromatic ring of a series of deuterium labeled n-alkylpyridinium ions with linear n-alkyl groups from Ci to Cie have been measured using 2H-NMR spectroscopy. These splittings were ...
-
(1991)A new differential pulse polarographic method is proposed for the determination of nicardipine, based on the electroactivity of the nitroaromatic group of the molecule. The proposed method is applied in the determination ...
-
(1993)Voltammetric studies of nimodipine using a mixed aqueous dimethylformamide (DMF) solvent have allowed us to generate the one-electron reduction product, the nitro radical anion RNO2 .. The cyclic voltammetry technique has ...
-
(Elsevier, 1967)The behaviour of uranium in both organic and inorganic supporting electrolytes is examined, and also the influence of complexing agents on the incision in the curve, dE/dt =f(E). The addition of TEA to supporting electrolytes ...
-
(1988)The enthalpies of the reaction between glutathione and amoxycillin have been measured directly using a flow microcalorimeter. Comparative results are obtained by using an ac polarographic method previously developed in our ...

-
(1994)A polarographic method for the determination of ranitidine is described, based on the reduction of the nitro group at a dropping-mercury electrode. The proposed method permits the drug to be determined, without any prior ...
-
(1990)The exposure of drugs to light produces photodecomposition processes in several cases: the drugs undergo important chemical changes with a parallel change in their activities or potencies and generally with a loss of their ...
-
(2013)A molecularly imprinted polypyrrole polymer-based film and its properties regarding the recognition of gallic acid were investigated. The polypyrrole film was prepared by including a template molecule during the ...
-
(2009)The relationship between the nanoscale structure of vanadium pentoxide nanotubes and their ability to accommodate Li+ during intercalation/ deintercalation is explored. The nanotubes are synthesized using two different ...
-
Solubilization of Alkylpyridinium Ions in Cationic Micelles: Effect of the Electrostatic Repulsion (1993)Binding constants of n-alkylpyridinium, CnPd+ (n = 10, 11, 12, 13, 14, and 16), to CTAX micelles, where X = Br− and Cl−, and to CTAOTOS were determined by ultrafiltration and a steady-state fluorescence method. These ...
-
(1996)Deuterium quadrupole splittings from the aromatic ring of a series of linear N-alkylpyridinium-d5 ions, with alkyl chains from 1 to 16 carbon atoms, were measured using 2H-NMR spectroscopy. The pyridinium ions, 10% deuteriated ...

Study of Aqueous Tetradecyltrimethylammonium Bromide-Brij 35 Solutions by Ion Activity Measurements (1989)Measurements of surfactant ion (tetradecyltrimethylammonium) and counterion (bromide) activities in binary tetradecyltrimethylaznmonium bromide (TTAB)-Brij 35 surfactant mixtures have been performed by using ion-specific ...
-
(2001)A series of S-nitrosothiol compounds, structurally related to the NO-donor S-nitroso-N-acetyl-D,L-penicillamine (SNAP) that contain amidin groups were synthesised by S-nitrosation of the corresponding thiols and characterised. ...
