Microstructure and composition design of magnetic Ni-Mn-Sn Co-sputter deposited films
(2015)"In this work, we study the effect of the substrate temperature (ST) during sputter-deposition as well as co-sputtering deposition on the fabrication of nanostructured Ni-Mn-Sn thin films. Sputtered films show Mn losses ... -
Microstructure and magnetocaloric effect of melt-spun Ni52Mn26Ga22 ribbon
(2012-04)"Microstructural features and magnetocaloric properties of Ni52Mn26Ga22 melt-spun ribbons were studied. Results show that there are four types of differently oriented variants of seven-layered modulated (7M) martensite at ... -
Modeling and optimization of a photocatalytic process: degradation of endocrine disruptor compounds by Ag/ZnO
(Elsevier, 2017)"Artificial neural network (ANN) modeling was applied to study the photocatalytic degradation of bisphenol-A. The operating conditions of the Ag/ZnO photocatalyst synthesis and its performance were simultaneously modeled ... -
Modelling adsorption isotherms of binary mixtures of carbon dioxide, methane and nitrogen
(2011)"A molecular-based approach for modelling mixtures adsorbed onto solid surfaces using the Statistical Associating Fluid Theory for Potentials of Variable Range (SAFT-VR) for three- and two-dimensional systems is presented ... -
Modificación de poliolefinas con poliésteres alifáticos para obtener compositos para aplicaciones biomédicas
(2022-03-21)"Compositos poliméricos a base de polietilenos, como el polietileno de alta densidad (HDPE) y el polietileno de ultra alto peso molecular (UHMWPE) y policaprolactona (PCL) con un relleno cerámico de bioglass (BG) e ... -
Modificación y evaluación de polímeros semiconductores para su potencial uso en dispositivos fotovoltaicos
(2019-11-15)"Actualmente las celdas perovskitas de vanguardia presentan una configuración convencional tipo n-i-p que consisten en óxido de titanio (TiO2), semiconductor tipo n, cubierto por la perovskita y una capa transportadora de ... -
Modification of porous nickel electrodes with silver nanoparticles for hydrogen production
(Elsevier, 2018)"Silver nanoparticles were electrodeposited into the surface of a macroporous Ni electrode. The developed electrodes were characterized morphologically by confocal laser scanning microscopy and field emission scanning ... -
Modified metallic oxides for efficient photocatalysis
(IntechOpen, 2018)"The aim of the chapter is to present modified materials like alternatives for conventional photocatalyst such as titanium dioxide. Discussion about silver/graphene nanoparticles-modified zinc oxide for the degradation of ... -
Multibranched gold nanoparticles coated with serum proteins fit for photothermal tumor ablation
(American Institute of Physics, 2020)"Photothermal tumor ablation might be carried out with multibranched gold nanoparticles (MBAuNPs) having maximum absorbance (A(max)) in the infrared region and functionalized with ligands that would bind them to the target ... -

Multifractal analyses of row sum signals of elementary cellular automata
(2012)"We first apply the WT-MFDFA, MFDFA, and WTMM multifractal methods to binomial multifrac-tal time series of three different binomial parameters and find that the WTMM method indicates an enhanced difference between the fractal ... -
Multifractal analysis of the symmetry of a strictly isospectral energy landscape on a square lattice
(Elsevier, 2021)"We use the Höder regularity analysis to study the symmetry breaking and recovery due to a parametric potential generated via the strictly isospectral factorization method. The initial potential is two-dimensional and ... -
Multifractal properties of elementary cellular automata in a discrete wavelet approach of MF-DFA
(2009)"In 2005, Nagler and Claussen (Phys. Rev. E 71, 067103 (2005)) investigated the time series of the elementary cellular automata (ECA) for possible (multi)fractal behavior. They eliminated the polynomial background atb ... -
Mutually unbiased bases and finite projective planes
(2004)"It is conjectured that the question of the existence of a set of d+1 mutually unbiased bases in a d-dimensional Hilbert space if d differs from a power of a prime number is intimately linked with the problem of whether ... -
Mutually unbiased phase states, phase uncertainties, and Gauss sums

N-step linear phase-shifting algorithms with optimum signal to noise phase demodulation
(2011)"A common way to test an optical wavefront is to use a phase-shifting interferometer along with (for example) a three-step linear phase-shifting algorithm (PSA). The following fundamental question arises: what phase step ... -
