79. Enhancement of bremsstrahlung radiation generated by electron beam interaction in an axially-oriented scintillator crystal

Riccardo Camattari (FE)

Poster

Since their discovery, scintillator materials have played an important role in nuclear and particle physics, as well as in medical and industrial imaging. In particular, inorganic scintillator crystals are widely exploited for the realization of homogeneous electromagnetic (e.m.) calorimeters for high-energy physics (HEP) and astrophysics to measure the energy of e± and of γ-rays. Since for...

85. Fault Diagnosis Based on Enhancement of Barkhausen Noise Using Hybrid Method Emprical Mode Decomposition-Savitzky-Golay Filter

Rabah Abdelkader (Research Center in Industrial Technologies CRTI, P.O.BOX 64, Cheraga 16014 Algiers, Algeria)

Poster

The barkhausen noise carries important information which can be used in early damage detection and fault diagnosis. The barkhausen noise is corrupted by interference signals from other sources during the measure and the information of fault can be lost. In this paper a new algorithm based on Empirical Mode Decomposition (EMD) and Savitzky-Golay is proposed to extract the information about the...

19. Magnetic Ordering of three Thiosemicarbazonecopper(II) Complexes

Dr Iñigo Etxebarria (Fisika Aplikatua II Saila, Euskal Herriko Unibertsitatea)

Poster

During the last decades, metal-organic compounds constitute an active field of research, and among them, complexes that combine thiosemicarbazone ligands with copper(II) are appealing from the point of view of material science due to their interesting structural and magnetic properties [1]. Complementary, they are also extensively studied due to biological and pharmacological applications that...

60. Manufacturing of bent silicon crystals for steering of particle beam at ultra-high energy synchrotrons

Melissa Tamisari (Istituto Nazionale di Fisica Nucleare)

Poster

Since the ’70, physics of interaction between bent crystals and heavy particles (protons or ions) is investigated at various worldwide particle accelerators, driven by the possibility to use bent crystals as optical elements for steering or focusing charged particle beams.
Recent improvements in crystal manufacturing techniques, joined with a deeper understanding of the physics behind...

22. Molecular and Elastic investigation of proteins self-assembling phenomena

Sara Catalini (European Laboratory for Non-Linear Spectroscopy (LENS))

Poster

Many biocompatible hydrogels are formed by the self-assembly of macromolecules, between these natural polypeptide-based hydrogels are very promising systems. They are good candidates for tissue engineering and drug delivery since they meet the majority of the design criteria for tailored biomaterials [1]. The balance between intramolecular and protein-solvent attractions determines the...

58. Radioisotope production through accelerators in crystalline targets

Giacomo Germogli (FE)

Poster

The production techniques of radioisotopes for medical purposes is a valuable and important field in nuclear medicine. In particular, the expensive cost of the prime materials for the production via cyclotron obliges the search for new solutions to enhance the production rate with minor upgrades of the current instrumentation. Oriented ordered structure can modify particle trajectories inside...

71. Structural, Morphological and Magnetic properties of Fe60-xCox(Al2O3)40 nanocomposite Coating deposited by thermal spraying

Abdo Younes (Research Center in Industrial Technologies )

Poster

FeCo/Al2O3 nanoparticles thermal sprayed on a steel plate with different Co concentration from 0 to 20% by means of a thermal spraying process, Fe60-xCox(Al2O3)40 powder alloy was synthesized using planetary ball mill for different Co concentration at 20 h of milling. The aims of this work are to study the effect of Co concentration and milling time on the magnetic, structural behavior and...

70. Structures, Optical and Mechanical properties of PLA/ ZnO SiO2 Al2O3 Composite Elaborated by a solvent casting method

Bouamer Amirouche (Research Center in Industrial Technologies)

Poster

In this study, granulated polylactic acid and ZnO, SiO2 and Al2O3 powders were mixed to form PLA/ZnO and PLA/ZnO SiO2 Al2O3 composites with different concentrations using a solvent casting method. The influences of ZnO, SiO2 and Al2O3 particles on the physical and mechanical properties of the PLA films were investigated. Chemical and crystal structures are characterized by FTIR-ATR,...

16. The structural origin of composition-driven magnetic transformation in BiFeO3-based multiferroics

Dr U. Khomchanka (CFisUC, Department of Physics, University of Coimbra, P-3004-516 Coimbra, Portugal)

Poster

Perovskite-like compounds are widely known as model systems for studying the relationships between crystal structure and physical properties. Among them, magnetically-ordered ferroelectric oxides have attracted much attention in recent years. Such materials combine spin and electric dipole ordering in the same phase, thus providing the technologically important possibility to control magnetism...
