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...
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...
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...
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...
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...
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,...
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...
