Inorganofunctionalization of Ti(IV) and Zr(IV) on the MCM-41 Surface and its Interaction with a Mixed Valence Complex to use as Isoniazid Sensing
(2021-01-01)
In this work, it describes the preparation of Titanium and Zirconium functionalized MCM-41 and subsequent chemical modification with nickel hexacyanoferrate. The obtained materials (MTiNiH and MZrNiH) were characterized ...
Electroreduction of 4-(nitrophenyl) substituted 1,4-dihydropyridines on the mercury electrode in aprotic medium
(Elsevier Ltd, 1997)
Electrochemical studies on 4-(nitrophenyl) substituted 1,4-dihydropyridines of pharmacological importance have allowed us to generate the one-electron reduction product, the nitro radical anion, ArNȮ- 2 , in aprotic media. ...
ESR and electrochemical study of 5-nitroindazole derivatives with antiprotozoal activity
(PERGAMON-ELSEVIER SCIENCE LTD, 2006-01)
The electrochemistry of 3-alkoxy- and 3-hydroxy-1-[(omega-(dialkylamino)alkyl]-5-nitroindazole derivatives were characterized using cyclic voltammetry in DMSO. The nitro reduction process was studied and this was affected ...
Unexpected effect of citrate ions on the corrosion process of carbon steel in alkaline solutions
(Elsevier, 2017-08-24)
The effect of citrate ions on the passive film stability on carbon steel, at pH 13, was evaluated. The study involved cyclic voltammograms, potentiodynamic polarization curves, micro-Raman spectroscopy and weight-loss ...
Characterisation of polypyrrole electrosynthesised on aluminium
(Pergamon-Elsevier Science Ltd, 2004-11)
Cyclic voltammetry has been used to investigate the role of the anions and the solution pH on the redox properties of polypyrrole electrosynthesised onto aluminium in alkaline solutions. The polymer film was characterised ...
Voltammetric studies of titanium (IV) phosphate modified with copper hexacyanoferrate and electroanalytical determination of N-acetylcysteine
(Springer, 2011-07-01)
Titanium (IV) Phosphate copper hexacyanoferrate composite (TiPhCuHCF) was prepared using a new methodology for the synthesis. A preliminary characterization of the precursor and resulting materials was defined using ...
Effect of hydrogen charging on the stability of SAE 10B22 steel surface in alkaline solutions
(Elsevier B.V., 2005-11-01)
The influence of hydrogen charging into a quenched and tempered boron steel membrane electrode (SAE 10B22) was studied using borate buffer (pH 8.4) and NaOH solutions (pH 12.7), with or without the addition of 0.01 M EDTA. ...
Spectroscopy and electrochemical characterization of Langmuir-Blodgett and physical vapor thin films of 29-membered diazocrown ether 1 with two n-octyl substituents
(Elsevier B.V. Sa, 2012-07-01)
UV-vis and FTIR spectroscopy and electrochemistry studies were performed on Langmuir-Blodgett (LB) and on physical vapor deposition (PVD) films of 29-membered diazocrown ether with two n-octyl substituents. FTIR and UV-vis ...
