The atomic-scale limits of magnetism and superconductivity explored by electron excitations in tunneling spectroscopy
(2019-01-25)
Esta tesis estudia los fenómenos de magnetismo y superconductividad a escala atómica por medio de Microscopía y Espectroscopía de Efecto Túnel a bajas temperaturas (STM/STS) en condiciones de ultra-alto vacío. Estos ...
Glass-Transition Dynamics of Mixtures of Linear Poly(Vinyl Methyl Ether) with Single-Chain Polymer Nanoparticles: Evidence of a New Type of Nanocomposite Materials
(MDPI, 2019-03-21)
Single-chain polymer nanoparticles (SCNPs) obtained through chain collapse by intramolecular cross-linking are attracting increasing interest as components of all-polymer nanocomposites, among other applications. We present ...
Controlling the stereospecific bonding motif of Au-thiolate links
(Royal Society of Chemistry, 2019-09-07)
Over the last decades, organosulfur compounds at the interface of noble metals have proved to be extremely versatile systems for both fundamental and applied research. However, the anchoring of thiols to gold remained an ...
Design of ancestral enzymes for engineering nanobiomaterials.
(2019-12-16)
La mejora de las enzimas para su uso industrial, donde las condiciones no son las naturales de las enzimas, es fundamental si queremos que operen de una forma eficiente. En esta tesis utilizamos una técnica llamada ...
Soft Magnetic Amorphous Microwires for Stress and Temperature Sensory Applications
(MDPI, 2019-12)
Amorphous ferromagnetic materials in the form of microwires are of interest for the development of various sensors. This paper analyzes and argues for the use of microwires of two basic compositions of Co71Fe5B11Si10Cr3 ...
Development of Magnetic Microwires for Magnetic Sensor Applications
(MDPI, 2019-11-02)
Thin magnetic wires can present excellent soft magnetic properties (with coercivities up to 4 A/m), Giant Magneto-impedance effect, GMI, or rectangular hysteresis loops combined with quite fast domain wall, DW, propagation. ...
Engineering of Magnetic Softness and Domain Wall Dynamics of Fe-rich Amorphous Microwires by Stress- induced Magnetic Anisotropy
(Nature Publishing, 2019-08-27)
We observed a remarkable improvement of domain wall (DW) mobility, DW velocity, giant magnetoimpedance (GMI) effect and magnetic softening at appropriate stress-annealing conditions. Beneficial effect of stress-annealing ...
Microwire-Based Sensor Array for Measuring Wheel Loads of Vehicles
(MDPI, 2019-10-26)
In this paper, a magnetic microwire-based sensor array embedded under the pavement is proposed as a weighing system at customs ports of entry. This sensor is made of a cementitious material suitable for embedding within ...
Impact of Stress Annealing on the Magnetization Process of Amorphous and Nanocrystalline Co-Based Microwires
(MDPI, 2019-08)
The domain wall (DW) dynamics of amorphous and nanocrystalline Co-based glass-coated microwires are explored under the influence of stress annealing. Different annealing profiles have enabled remarkable changes in coercivity ...
Magnetic properties of “thick” glass-coated Fe-rich microwires
(American Institute of Physics, 2019-03)
We report on preparation and magnetic properties of Fe71.7B13.4Si11Nb3Ni0.9 glass-coated microwire with metallic nucleus diameter d = 103 mu m and total diameter D = 158 mu m prepared by Taylor-Ulitovsky method. Amorphous ...
