Electrochemical oxidation of diethylenetriamine (DETA) charged with 0.1 M LiSO3CF3, leads to a polymeric coating (polyethyleneimine film: PEI) on the porous silicon (PS) surface. The obtained passivated electrode is characterized through IRTF spectro

Liquid ammoniates, which are highly conductive electrolyte (more than 100 mS.cm-1 at 20 °C), are proposed as solvents for a redox battery working around room temperature, and up 80 °C. In the negative compartment, the anolyte is NaI · 3.3NH3, and

It is shown that the conductivities of LiBF4, LiPF6, LiN(SO2CF3)2 (LiTFSI), NaPF6, KPF are abnormally high in two diamine solvents: ethylenediamine (EDA) and 1,3-diaminopropane (1,3 DAP). This is particularly evident for KPF6, κMAX(EDA) = 35 mS cm

Five potentiometric pH sensors based on thin polymer films, obtained from electropolymerization of their respective monomers: 1,3-diaminopropane, diethylenetriamine, pyrrole, p-phenylenediamine and aniline, were compared. All these molecules have bee

It is shown that not only the relative permittivity or the dynamic viscosity, but also the chemical nature of the salt and that of the solvent can be taken into account to predict the most important properties of electrolytes: the conductivity maximu

This study concentrates on two polymers: linear polyethylenimine, L-PEI, and linear polypropylenimine, L-PPI. Detailed atomistic molecular models have been developed with the help of ab initio and quantum-mechanical calculations. The vibrational spec

The development of a new electrochemical sensor consisting in a glass-sealed metal microelectrode coated by a polyethylenimine film is described. The use of polymers as the entrapping matrix for enzymes fulfils all the requirements expected for these

The aim of this work was to elaborate on a thin polymeric film for coating transparent fluorine-doped tin oxide (FTO) electrode supported on a glass substrate for trapping Cu 2 + ions. Possible applications are the easier detection of Cu 2 + ions due

The electrochemical oxidation of paraphenylenediamine (1,4-diaminobenzene, PPD) leads to the passivation of the electrode surface by a thin film as shown by using Cyclic Voltammetry technique. This film can be identified by InfraRed-Attenuated Total

Thin polyethyleneimine (PEI) films were deposited on p-silicon-based transducers. The polymer acts at the same time as the insulator and the sensitive membrane of an electrolyte/insulator/semiconductor (EIS) structure. Electrochemical measurements su
