2D-Coordination polymers based on 1H-indazole-4-carboxylic acid and transition metal ions: magnetic, luminescence and biological properties
(Royal Society of Chemistry, 2020-08-14)
We report the formation of five novel multifunctional coordination polymers based on 1H-indazole-4-carboxylic acid (HL). To the best of our knowledge, these complexes are the first examples of coordination compounds ...
Biological and synthetic approaches to inhibiting nitrification in non‑tilled Mediterranean soils
(Springer, 2021-10-13)
[EN] Background: The increasing demand for food production has led to a tenfold increase in nitrogen (N) fertilizer use since the Green Revolution. Nowadays, agricultural soils have been turned into high-nitrifying ...
Co-Catalyzed C(sp3)−H Oxidative Coupling of Glycine and Peptide Derivatives
(American Chemical Society, 2017-09-22)
obalt-catalyzed selectiveα-alkylation andα-heteroarylation processes ofα-amino esters and peptide derivativesare described. These cross-dehydrogenative reactions occur undermild conditions and allow for the rapid assembly ...
América Latina ante las demandas inversor-estado
(Sociedad de Economía Mundial, SEM-WES, 2012-09)
Este artículo estudia las demandas presentadas por empresas multinacionales contra estados latinoamericanos en instancias internacionales
de arbitraje. Como esas demandas derivan de la suscripción de numerosos acuerdos ...

Relativistic force between fast electrons and planar targets
(IOP Publishing, 2014-07-30)
The full retarded electromagnetic force experienced by swift electrons moving parallel to planar boundaries is revisited, for both metallic and dielectric targets, with special emphasis on the consequences in electron ...
Emotional Self-Regulation in Primary Education: A Heart Rate-Variability Biofeedback Intervention Programme
(MDPI, 2022-04-30)
This study investigated the benefits of using a biofeedback intervention programme to train children in controlling their heart rate variability (HRV) through slow-paced breathing in real time. HRV biofeedback interventions ...
Role of Eu2+ and Dy3+ Concentration in the Persistent Luminescence of Sr2MgSi2O7 Glass-Ceramics
(MDPI, 2022-04-22)
In this study, glass-ceramics based on Sr2MgSi2O7 phosphor co-doped with Eu/Dy were obtained from the sintering and crystallisation of glass powders. The glasses were melted in a gas furnace to simulate an industrial ...
On the Stabilization through Linear Output Feedback of a Class of Linear Hybrid Time-Varying Systems with Coupled Continuous/Discrete and Delayed Dynamics with Eventually Unbounded Delay
(MDPI, 2022-04-23)
This research studies a class of linear, hybrid, time-varying, continuous time-systems with time-varying delayed dynamics and non-necessarily bounded, time-varying, time-differentiable delay. The considered class of systems ...
Parental Burnout Assessment (PBA) in Different Hispanic Countries: An Exploratory Structural Equation Modeling Approach
(Frontiers Media, 2022-04-07)
Parental burnout is a unique and context-specific syndrome resulting from a chronic imbalance of risks over resources in the parenting domain. The current research aims to evaluate the psychometric properties of the Spanish ...
