Plenary Lecture:          First-order Reversal Curves (FORC) Diagram Characterization Technique of Hysteretic Processes

Abstract: One of the most significant contributions to the development of characterization techniques in magnetism is based on the measurement of a special category of minor loops known as first-order reversal curves (FORC) instead of the well-known use of the data from the major hysteresis loop. Typically, 100 FORCs that cover the surface of the major hysteresis loop are sufficient to produce an experimental FORC diagram. This diagram was for many years seen as a sort of magnetic sample fingerprint and was used to identify various phases present in the magnetic materials. This initial success was the fundament for the effort to transform the method from a virtually qualitative one to a powerful quantitative tool able to identify not only the presence of different phases but also to give information about the distribution of the coercive fields and of the intensity of interactions between the ferromagnetic particles/domains. The method was recently applied in other fields of physics and gradually became the standard characterization tool of hysteretic processes observed in ferroelectricity, geology, archeology, spin-transition materials, etc. The main research effort in the last few years is focused on the developing of the tools to improve the strength of the FORC diagram technique as a quantitative one able to provide a wealth of physical information in various technological problems. The talk will present the state-of-the-art in the FORC technique and the main recent developments in this area.

Plenary Lecture:          Measuring Biological Interactions at the Single-Molecule Level by Atomic Force Microscopy

Abstract: Long- and short-range interactions between life macromolecules are very important for the energetic comportment of biological systems. The investigation of these interactions by thermodynamic and kinetic approaches does not provide an accurate evaluation of the intermolecular binding because the well-defined quantitation of the force (the derivative of energy with respect to separation distance) is not possible. In order to obtain in-depth data concerning the distribution of interaction energy, i.e. binding strength, between two biological structures, we have used atomic force microscopy (AFM). The atomic force microscope is a proper device for quantifying intermolecular forces between nanometer-scale entities. The intrinsic interactions can be measured in real time with a high three-dimensional resolution. By means of AFM we investigated the interaction between cell adhesion macromolecules in well-defined physiological conditions. We selected the glyconectin 1 (GN1) as a model system (a cell adhesion proteoglycan isolated from the marine sponge Clathria prolifera). The GN1 mediates in vivo cell recognition and adhesion via homophilic, specific, polyvalent, and calcium ion-dependent glycan-glycan interactions.

Plenary Lecture:          Upper Bounds for Photothermal and Photovoltaic Conversion Efficiency

Abstract: The available work exergy of thermal radiation may be derived ab initio by using a simple statistical thermodynamic approach. A general upper bound exists for the efficiency of thermal radiation conversion into work. This efficiency is different from the Carnot efficiency and generalizes the Petela efficiencylike factor appearing in the available work of blackbody radiation. The maximum efficiencies of photothermal and photovoltaic conversions are particular cases of this general result. One proves by using available work considerations that the maximum efficiency of photothermal conversion is higher than the maximum efficiency of photovoltaic conversion.

Plenary Lecture:          Electrostatic Processes Applications of Electrical Discharges

Abstract: Most electrostatic processes involve the action of electric field forces on electrically charged bodies. The corona discharge is frequently used as charging mechanism in such processes. Thus, DC corona-charged dust particles can be captured by the electrodes of electrostatic filters, while the non-conductive constituents of a granular mixture can be separated from the conductive ones in the electric field of a corona-electrostatic separator. DC corona exposure of non-woven textiles for filtering media can significantly enhance their particle collection efficiency. The dielectric barrier discharge can modify the surface state of the materials exposed to it. For instance, this non-thermal plasma treatment may enhance the efficiency of the tribocharging process of granular mixed plastic wastes in view of their electrostatic separation. The presentation will briefly describe recent applications of corona and dielectric barrier discharges developed by the PPRIME Institute of the University of Poitiers, France, in partnership with researchers from “Politehnica” University in Bucharest, Technical University of Cluj-Napoca and University of Sidi-Bel-Abbes, Algeria. R & D of new electrostatic processes can largely benefit from the use of these techniques.
