Nonlinear stability in the spatial attitude motion of a satellite in a circular orbit
(Society for Industrial and Applied Mathematics Publications, 2021)
info:eu-repo/semantics/article,
The paper considers the attitude nonlinear stability analysis of the spatial satellite problem and takes it one step further. A study of the Lie (formal) stability is presented and long-time estimates related to the Lie ...
Lipschitz free spaces isomorphic to their infinite sums and geometric applications
(American Mathematical Society, 2021)
info:eu-repo/semantics/article,
We find general conditions under which Lipschitz-free spaces over metric spaces are isomorphic to their infinite direct _1-sum and exhibit several applications. As examples of such applications we have that Lipschitz-free ...
Contactless magnetic nanoparticle detection platform based on non-linear GMI effect
(Elsevier, 2021)
info:eu-repo/semantics/article,
A detection platform based on non-linear Giant Magnetoimpedance Effect was analyzed for the design of a contactless and low-cost detector of magnetic nanoparticles. The sensor consists of two soft magnetic amorphous wires ...
Luminance calibration of a full sky HDR imaging system using sky scanner measurements
(Solar Energy Society, 2022)
Artículo / Artikulua,
A full sky High Dynamic Range imaging system, based on a Single-Lens Reflex camera with a fisheye lens, has been constructed and calibrated with a sky scanner luminance meter. The method considers the geometrical, spectral, ...
Nonlinear stability of elliptic equilibria in Hamiltonian systems with exponential time estimates
(American Institute of Mathematical Sciences (AIMS), 2021)
Artículo / Artikulua,
In the framework of nonlinear stability of elliptic equilibria in Hamiltonian systems with n degrees of freedom we provide a criterion to obtain a type of formal stability, called Lie stability. Our result generalises ...
Nanoparticle size distribution and surface effects on the thermal dependence of magnetic anisotropy
(ACS Publications, 2022)
info:eu-repo/semantics/article,
Standard approaches to investigate the anisotropy of nanoparticle assemblies are either by means of zero-field-cooled-field-cooled DC magnetization curves or by analyzing the coercivity at low temperatures. However, these ...
Catalytic photodegradation of organic compounds using TiO2/pillared clays synthesized using a nonconventional aluminum source
(Elsevier, 2022)
Artículo / Artikulua,
This study evaluates the photocatalytic degradation of 2,6-dichlorophenol (2,6-DCP), triclosan (TCS) and bisphenol A (BPA) by ultraviolet (UV) and visible (VIS) light in the presence of TiO2/catalysts synthesized by wet ...
Cellulose polymers with β-amino ester pendant group: design, synthesis, molecular docking and application in adsorption of toxic metals from wastewater
(BioMed Central, 2022)
Artículo / Artikulua,
Background: Cellulose polymers with multidentate chelating functionalities that have high eficiency for toxic metal
ions present in water were designed, synthesized, and analyzed. The synthesis was carried out by reacting ...
Induction of radiata pine somatic embryogenesis at high temperatures provokes a long-term decrease in DNA methylation/hydroxymethylation and differential expression of stress-related genes
(MDPI, 2020)
info:eu-repo/semantics/article,
Based on the hypothesis that embryo development is a crucial stage for the formation of stable epigenetic marks that could modulate the behaviour of the resulting plants, in this study, radiata pine somatic embryogenesis ...
Tailoring magnetic and transport anisotropies in Co100−x –Cux thin films through obliquely grown nano-sheets
(MDPI, 2022)
info:eu-repo/semantics/article,
The magnetic and transport properties of pulsed laser-deposited Co100−x –Cux thin films were tailored through their nano-morphology and composition by controlling for the deposition geometry, namely normal or oblique ...
