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 ...
Magnetic and structural characterization of magnetite nanoparticles synthesized by magnetotactic bacteria.
(2018-10-29)
Las bacterias magnetotácticas son un grupo microorganismos capaces de orientarse en presencia delcampo magnético terrestre, lo que les facilita la búsqueda de un entorno rico en nutrientes y con lascondiciones de oxígeno ...
An Advanced Control Technique for Floating Offshore Wind Turbines Based on More Compact Barge Platforms
(MDPI, 2018-05)
Hydrodynamic Floating Offshore Wind Turbine (FOWT) platform specifications are typically dominated by seaworthiness and maximum operating platform-pitch angle-related requirements. However, such specifications directly ...
Magnetic field-induced rubber-like behavior in Ni-Mn-Ga particles/polymer composite
(Nature Publishing, 2019-03-05)
Single crystalline Ni-Mn-Ga is well known as a prototype ferromagnetic shape memory alloy (FSMA) exhibiting a giant magnetic field-induced strain (MFIS), up to 12%, due to the magnetically driven twin boundary rearrangement. ...
Advanced control for floating offshore wind turbines.
(2019-05-31)
os aerogeneradores flotantes presentan diversos retos tecnológicos, entre los cuales, las atenuaciones de la dinámica producida por el empuje del viento y la inducida por el oleaje, debido a la baja rigidez hidrodinámica ...
PPF-Dependent Fixed Point Results for New Multi-Valued Generalized F-Contraction in the Razumikhin Class with an Application
(MDPI, 2019-01-07)
In this paper, a new multi-valued generalized F-contraction mapping is given. Using it, the existence of PPF-dependent fixed point for such mappings in the Razumikhin class is obtained. Moreover, an application for nonlinear ...
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 ...
Removal of Tetracycline Pollutants by Adsorption and Magnetic Separation Using Reduced Graphene Oxide Decorated with Alpha-Fe₂O₃ Nanoparticles
(MDPI, 2019-02-26)
Nanocomposites of reduced graphene oxide (RGO) with ferromagnetic alpha-Fe₂O₃ nanoparticles have been prepared in-situ by thermal treatment. The structure and morphology of the hybrid material were studied by X-ray ...
A Feedback Control Loop Optimisation Methodology for Floating Offshore Wind Turbines
(MDPI, 2019-09-10)
Wind turbines usually present several feedback control loops to improve or counteract some specific performance or behaviour of the system. It is common to find these multiple feedback control loops in Floating Offshore ...
Magnetoimpedance in Symmetric and Non-Symmetric Nanostructured Multilayers: A Theoretical Study
(MDPI, 2019-04-12)
Intensive studies of the magnetoimpedance (MI) effect in nanostructured multilayers provide a good phenomenological basis and theoretical description for the symmetric case when top and bottom layers of ferromagnet/condu ...
