Enhanced mass sensitivity in novel magnetoelastic resonators geometries for advanced detection systems
(Elsevier, 2019-10-01)
Acoustic wave based sensors have a major impact in the detection of low concentration of biological and chemical agents. Magnetoelastic resonator platforms are particularly interesting due to their low cost and wireless ...
Mechanical Force Acting on Ferrogel in a Non-Uniform Magnetic Field: Measurements and Modeling
(MDPI, 2022-07-23)
[EN] The development of magnetoactive microsystems for targeted drug delivery, magnetic biodetection, and replacement therapy is an important task of present day biomedical research. In this work, we experimentally studied ...
Neutron Scattering as a Powerful Tool to Investigate Magnetic Shape Memory Alloys: A Review
(MDPI, 2021-05-18)
Magnetic shape memory alloys (MSMAs) are an interesting class of smart materials characterized by undergoing macroscopic deformations upon the application of a pertinent stimulus: temperature, stress and/or external magnetic ...
Temperature Dependent Stress–Strain Behavior and Martensite Stabilization in Magnetic Shape Memory Ni51.1Fe16.4Ga26.3Co6.2 Single Crystal
(MDPI, 2021-06-04)
The superelastic properties and stress-induced martensite (SIM) stabilization have been studied in a shape memory Ni51.1Fe16.4Ga26.3Co6.2 single crystal. The single crystal, characterized by a thermally induced forward ...
A New Four-Step Iterative Procedure for Approximating Fixed Points with Application to 2D Volterra Integral Equations
(MDPI, 2022-11-14)
This work is devoted to presenting a new four-step iterative scheme for approximating fixed points under almost contraction mappings and Reich–Suzuki-type nonexpansive mappings (RSTN mappings, for short). Additionally, we ...
Exchange biased FeNi/FeMn bilayers with coercivity and switching field enhanced by FeMn surface oxidation
(AIP Publishing, 2013-09)
FeNi/FeMn bilayers were grown in a magnetic field and subjected to heat treatments at temperatures of 50 to 350 degrees C in vacuum or in a gas mixture containing oxygen. In the as-deposited state, the hysteresis loop of ...
Size Dependence of the Magnetoelastic Properties of Metallic Glasses for Actuation Applications
(MDPI, 2019-10-04)
We present an exhaustive study of the magnetoelastic properties of 24 strips with different rectangular dimensions, cut from a long ribbon of Metglas((R)) 2826MB3. The strips have a length-to-width ratio R = L/w ranging ...
ANN-Based Airflow Control for an Oscillating Water Column Using Surface Elevation Measurements
(MDPI, 2020-01-29)
Oscillating water column (OWC) plants face power generation limitations due to the stalling phenomenon. This behavior can be avoided by an airflow control strategy that can anticipate the incoming peak waves and reduce its ...
Accurate Determination of the Q Quality Factor in Magnetoelastic Resonant Platforms for Advanced Biological Detection
(MDPI, 2018-03)
The main parameters of magnetoelastic resonators in the detection of chemical (i.e., salts, gases, etc.) or biological (i.e., bacteria, phages, etc.) agents are the sensitivity S (or external agent change magnitude per Hz ...
