“…21,22 Moreover, by working at low temperature both the electron transfer kinetics and reaction kinetics are attenuated thus allowing more insight into the mechanisms that are involved. 17,18 These electrochemical studies show, in this case, an agreement between the solution electron transfer results and intrinsic physical parameters.…”

“…Using THF as the electrolyte solvent is particularly interesting in regard of the large cathodic potential window available for electrochemical measurements. 1,13,[17][18][19][20][21] In contrast to macroelectrodes, microelectrodes allow the acquisition of voltammograms that are negligibly affected by the high resistivity of the medium. 21,22 Moreover, by working at low temperature both the electron transfer kinetics and reaction kinetics are attenuated thus allowing more insight into the mechanisms that are involved.…”

“…Over the past 5 years, a protocol and a methodology for electrochemical studies in tetrahydrofuran (THF) at low temperatures was developed in our laboratory 1–14. Our interest in this work was initiated by a wish to work in conditions that would be similar to those typical for the synthetic work using reductions by lithium metal.…”

“…Electrochemical studies in THF were initiated more than 40 years ago by Périchon and Buvet,15–19 and, as far as experiments at low temperature are concerned, Van Duyne and Reilley20–22 were the first to design electrochemical studies of unstable species at temperatures down to 178 K for DCM and even down to 93 K for butyronitrile. Apart from our own recent studies,1–14 a very limited number of electrochemical studies have been performed in THF at low temperature 23–25. The advantages of working at low temperature will be briefly reviewed in this paper.…”

This review describes the protocol, procedures and methods for electrochemical studies in THF and at low temperature that have been developed in the course of the last 5 years in our laboratory. Electrochemical studies in THF benefit from a large accessible potential window. In practice, it is however necessary to avoid the presence of humidity in the electrochemical cell. A specific reference electrode had to be designed for those measurements. Microelectrodes, the voltammetric response of which is negligibly affected by the resistivity of the medium, were preferred to macroelectrodes. Moreover, a methodology has been developed for the quantitative analysis of both voltammetric and chronoamperometric curves obtained for the microelectrodes. The fitting of chronoamperometric measurements using the Shoup and Szabo's expression allows us to estimate the diffusion coefficient of the substrate. The modelling of the cyclic voltammograms measured over a large range of scan rates allows the confirmation of the diffusion coefficient of the substrate D A , the determination of the diffusion coefficient of the electrogenerated molecule D B , of the formal potential E 0 f , of the transfer coefficient a and of the standard heterogeneous rate constant for the electron transfer k 0 . Typically, systems are investigated at temperatures ranging from room temperature to 192 K. Parameters obtained at various temperatures are used to extract, through Arrhenius plots, the activation energies both for the diffusion coefficient E A (D) and for the electron transfer reaction E A (k 0 ).

“…The aspects of low temperature electrochemistry did develop as cryoelectrochemistry [125]. Cryoelectrochemistry (at around −70 • C), however, has been limited to electrochemical analysis in nonpolar solvents [126][127][128] and has rarely been investigated for aqueous solutions and electrochemical synthesis. Studies have been limited to synthesis of insoluble products to as low as 10…”

This review discusses briefly the important aspects of thin films. The introduction of the article is a summary of evolution of thin films from surface engineering, their deposition methods, and important issues. The fundamental aspects of electrochemical deposition with special emphasis on the effect of temperature on the phase formation have been reviewed briefly. The field of sonoelectrochemistry has been discussed in the paper . The literature regarding the effects of temperature and sonication on the structure and morphology of the deposits and nucleation mechanisms, residual stress, and mechanical properties has also been covered briefly.
