The studies at UPR15 are performed in the context of physico-chemistry and interfacial reactivity. Various domains are concerned: corrosion and its inhibition, surface treatments, storage and conversion of energy, and, more recently, applications in biology, cultural patrimony protection, and, more generally, natural environments to understand the behaviour of electrochemical interfaces. This explains why the laboratory is positioned at the junction of fundamental research, its primary assignment, and activities with partners of various economic sectors using electrochemical concepts, techniques, and processes.


Development of methods dealing with concepts of electrochemical kinetics and design of sophisticated instrumentation able to apply these concepts to various physicochemical processes occurring at metal-electrolyte interfaces.

Preparation or modification, structural or chemical characterization of electrochemical interfaces and systems, modelling of their electrochemical behaviour. This activity may lead to the characterization of specific functionalities and to the development of innovative applications.


I. Measurement methodology and experimental developments in electrochemistry

Control and development of original characterization methods are a strong axis of LISE to study the kinetics of complex electrochemical phenomena. The skills of LISE are recognized all over the world in the fields of electrochemical impedance spectroscopy and multiple transfer functions (electric, gravimetric, mass transfer). Theme #1 of the 2007-2012 activity report of the laboratory presents techniques recently developed to study local and transient electrochemical phenomena at various scales (local impedance, SECM, AFM and CS-AFM, STM, bi or tri-electrodes). Coupling techniques (impedance-Raman, impedance-noise, electrochemistry-AFM), which is not possible with available commercial equipments, is also an important development axis to reach additional physico-chemical parameters.

II. Modelling of electrochemical kinetics

Theme #2 presents some examples of kinetic phenomena models for various systems, from model or complex interfaces to electrolytic media. These modellings, performed systematically in support of experimental measurements, are sometimes still based on analytical calculations but, more and more, numerical calculations by finite elements using commercial software (COMSOL…) are involved.

III. Thin layer materials: development and applications in electrochemistry

Preparation of thin films with specific functionalities in LISE allows a better control of their properties and thus helps modelling their behaviour. A spray pyrolysis reactor is available in LISE for the synthesis of transparent electrodes of strongly doped tin dioxide. Two cathode sputtering reactors are also available, one of them being dedicated to the preparation of amorphous thin layers of nitrogenated and hydrogenated carbon (a-C:N:H) as substitutes to boron-doped diamond. Theme #3 describes the reactivity properties of materials elaborated using these reactors or electrochemical and soft chemistry methods. The expected applications are clearly related to the environment field (water treatment, biocide surfaces, biosensors, chemical sensors) or the energy field (photoelectrochemistry, storage, active protection of metals).

IV. Corrosion and protection against corrosion

The objective of Theme #4 is the comprehension of the corrosion mechanisms and the implementation of protection methods in very diverse systems. The elaboration of anti-corrosion protection methods from the study of the corrosion mechanisms represents a significant part of the requests of the industry (automobile, metallurgy, chemistry…) at UPR 15, in the context of sustainable development and drastic environmental regulations. Theme #4 strongly profits from the development of the innovating techniques and the numerical models described in Theme #1 and 2, in particular the local electrochemical methods to study localized corrosion by pitting or cracking, and from the development of original devices as the thin layer cell to study corrosion in confined media.

V. Electrochemistry and environment

Theme #5 concerns very various fields related to environment, in particular natural environments (formation of calco-magnesian deposit or scale, biocide surfaces, bioanalysis, biocorrosion of steel in nuclear plants…). Sensors have been devised to detect various entities (specific proteins, water pollutants like nitrate, toxic micro-organisms…) and miniaturized systems (microchannels, microelectrode networks, electroacoustic microsystems), as well as new detection means for these microsystems, have been developed for bioanalysis (electrical and/or optical transductions).
