The functionalization process is followed mainly by x-ray photoemission spectroscopy. Indeed, determining the chemical environment around carbon or nitrogen atoms allows to evidence the formation of covalent bounding. In addition, the signatures of iron and copper ions give information on the effective growth of hexacyanoferrate nanoparticles. Furthermore, the cesium sorption mechanism is investigated by comparing the peak intensities associated to the response of potassium and cesium ions. Finally, based on the liquid chromatography analyzes, the sorption of cesium with the functionalized carbon supports is studied. The main results of this work are the demonstration of both a good selectivity of cesium trapping and a high sorption capacity by hybrid single-walled carbon nanotubes.</p></div>2018-07-11T21:52:07+00:00Copyright (c) 2018 Hajer Draouil, Laurent Alvarez, Jeremy Causse, Valerie Flaud, Mohamed Zaïbi, Jean-Louis Bantignies, Meherzi Oueslati, Julien Cambedouzouhttp://caip.co-ac.com/index.php/materialsanddevices/article/view/34Investigation of DNA denaturation from generalized Morse potential2018-09-27T12:52:38+00:00radouane el kinaniradouane_kin@yahoo.fr<p>In this paper, we present a non-linear model for DNA denaturation. We assume that the double-strands DNA interact via a realistic generalized Morse potential that reproduces well the features of the real interaction, as well as the used DNA model and that of Peyrard and Bishop. Using the <em>Transfer Matrix Method</em>, based on the resolution of a Schrödinger equation, we first determine <em>exactly </em>their solution, which are found to be <em>bound states</em>. Second, from an exact expression of the ground state, we compute the denaturation temperature and the free energy density, in terms of the potential parameters. Then, we calculate the contact probability, which is the probability to find the double-strands at a (finite) distance apart. The main conclusion is that, the present analytical study reveals that the generalized Morse potential is a good candidate for the study of DNA denaturation.</p>2018-07-11T21:52:07+00:00Copyright (c) 2018 radouane el kinanihttp://caip.co-ac.com/index.php/materialsanddevices/article/view/66Lecture on the anomalous diffusion in Condensed Matter Physics2018-09-27T12:52:39+00:00Mabrouk Benhamoum.benhamou@ensam-umi.ac.maDiffusion is a natural or artificial process that governs many phenomena in nature. The most known diffusion is the Brownian or normal motion, where the mean-square-displacement of the tracer (diffusive particle among others) increases as the square-root of time. It is not the case, however, for complex systems, where the diffusion is rather <em>slow</em>, because at small-scales, these media present an heterogenous structure. This kind of slow motion is called <em>subdiffusion</em>, where the associated mean-square-displacement increases in time, with a non trivial exponent, alpha, whose value is between 0 and 1. In this review paper, we report on new trends dealing with the study of the anomalous diffusion in Condensed Matter Physics. The study is achieved using a theoretical approach that is based on a <em>Generalized Langevin Equation</em>. As particular crowded systems, we choose the so-called Pickering emulsions (oil-in-water), and we are interested in how the dispersed droplets (protected by small solid charged nanoparticles) can diffuse in the continuous phase (water). Dynamic study is accomplished through the mean-square-displacement and the velocity-autocorrelation-function. Finally, a comparison with <em>Molecular Dynamics</em> data is made.2018-08-27T00:00:00+00:00Copyright (c) 2018 Mabrouk Benhamou
