Thermal behavior, spectroscopic study and evolved gas analysis (EGA) during pyrolysis of picolinic acid, sodium picolinate and its light trivalent lanthanide complexes in solid state
(2016-05-01)
Synthesis, characterization, and thermal behavior of light trivalent lanthanide picolinate (La-Gd, except Pm) as well as the thermal behavior of picolinic acid and its sodium salt were investigated employing elemental ...
Nucleation and growth of silver nanostructures onto HOPG electrodes in the presence of picolinic acid
(Elsevier Science, 2013-01)
Silver electrodeposition onto HOPG electrodes in the presence of picolinic acid (PA) has been studied by cyclic voltammetry and chronoamperometry. Changes in the nucleation and growth mechanisms, which are dependent on the ...
Spectroelectrochemical study of picolinic acid adsorption during silver electrodeposition
(Pergamon-Elsevier Science Ltd, 2015-02)
The adsorption of picolinic acid (PA) onto HOPG electrodes during silver electrodeposition at pH 3.0 was examined using conventional electrochemical techniques: cyclic voltammetry and impedance measurements (differential ...
Ruthenium (II) phosphine/picolinate complexes as antimycobacterial agents
(Elsevier France-editions Scientifiques Medicales Elsevier, 2010-02-01)
The synthesis, characterization and the anti-Mycobacterium tuberculosis (MTB) activities of three ruthenium complexes containing the 2-pyridinecarboxylic acid anion (picolinate), with formulae cis-[Ru(pic)(dppm)(2)]PF(6) ...

Novel solid-state compounds of heavy rare-earth (III) picolinates. A pyrolytic study using: TG-DSC-IR, HSM-MS and GC-MS
(2019-11-01)
Heavy trivalent lanthanides and yttrium picolinates were synthesized by complexation of basic rare-earth metal carbonates with an aqueous solution of picolinic acid. The novel compounds were obtained with the general formula ...
Estudo da atividade antibacteriana do picolinato de sacarose em Escherichia coli
(2013-11-19)
Sucrose esters are generally used as surfactants, fat substitutes and antibiotics. The aim of the present study was to synthesize new sucrose esters derived from picolinic acid (2-pyridine carboxylic acid) and study in ...
Monitoring of Silver Electrodeposition onto HOPG Electrodes in the Presence of Picolinic Acid by in Situ Surface-Enhanced Raman Spectra Measurements
(American Chemical Society, 2014-02)
In situ surface-enhanced Raman spectra (SERS) have been recorded during silver potentiodynamic electrodeposition onto HOPG electrodes from solutions containing silver perchlorate and picolinic acid (PA). Modification of ...
