Original Approach to Synthesize TiO2/ZnO Hybrid Nanosponges Used as Photoanodes for Photoelectrochemical Applications
2021
[EN] In the present work, TiO2/ZnO hybrid nanosponges have been synthesized for the first time. First, TiO2 nanosponges were obtained by anodization under hydrodynamic conditions in a glycerol/water/NH4F electrolyte. Next, in order to achieve the anatase phase of TiO2 and improve its photocatalytic behaviour, the samples were annealed at 450 degrees C for 1 h. Once the TiO2 nanosponges were synthesized, TiO2/ZnO hybrid nanosponges were obtained by electrodeposition of ZnO on TiO2 nanosponges using different temperatures, times, and concentrations of zinc nitrate (Zn(NO3)(2)). TiO2/ZnO hybrid nanosponges were used as photoanodes in photoelectrochemical water splitting tests. The results indi…

Mass Accretion Processes in Young Stellar Objects: Role of Intense Flaring Activity
2014
According to the magnetospheric accretion scenario, young low-mass stars are surrounded by circumstellar disks which they interact with through accretion of mass. The accretion builds up the star to its final mass and is also believed to power the mass outflows, which may in turn have a significant role in removing the excess angular momentum from the star-disk system. Although the process of mass accretion is a critical aspect of star formation, some of its mechanisms are still to be fully understood. On the other hand, strong flaring activity is a common feature of young stellar objects (YSOs). In the Sun, such events give rise to perturbations of the interplanetary medium. Similar but mo…
La Ley 17/2021, de 15 de diciembre, ¿hasta qué punto es trasunto de la frustrada proposición de ley de modificación del Código Civil, la Ley Hipoteca…
2022
La virtud de la buena política consiste en aprehender los consensos sociales y saberlos plasmar en normas útiles con vocación de avance y mejora. La Ley 17/2021 es una buena demostración de ello, y el proceso que llevó a su aprobación refuerza el papel del Parlamento como institución que sabe dar continuidad al trabajo realizado en su seno, más allá de las sustituciones en las personas que lo desarrollaron. El propósito del presente artículo es mostrar cómo en 2017 ya existía en España el consenso suficiente para impulsar mediante una Proposición de Ley la reforma de nuestro anacrónico Código Civil para ponerlo al día con las nuevas convicciones ciudadanas sobre la necesidad de respetar a l…
Una experiencia efímera: Enrique de Benito y el Instituto de Estudios Penales de la Universidad de Valencia (1928-1930)
2020
El auge de la Criminología en la segunda mitad del siglo XIX y en los primeros treinta años del XX dio lugar a una pequeña pero importante escuela de criminólogos españoles. El éxito del correccionalismo, junto con la extensión de las teorías de la Escuela Positiva italiana, dio lugar a la creación del Laboratorio de Criminología en Madrid, y la Escuela de Criminología para funcionarios o enseñanzas complementarias al Derecho Penal. En Valencia, la creación del Instituto de Estudios Penales, impulsado por el profesor Enrique De Benito fue una de esas experiencias. De corta trayectoria, el Instituto, con un plantel de profesores multidisciplinar y con un programa que abarcaba los conocimient…

Selective Antimicrobial Effects of Curcumin@Halloysite Nanoformulation: A Caenorhabditis elegans Study
2019
Alterations in the normal gastrointestinal microbial community caused by unhealthy diet, environmental factors, and antibiotic overuse may severely affect human health and well-being. Novel antimicrobial drug formulations targeting pathogenic microflora while not affecting or even supporting symbiotic microflora are urgently needed. Here we report fabrication of a novel antimicrobial nanocontainer based on halloysite nanotubes loaded with curcumin and protected with a dextrin outer layer (HNTs+Curc/DX) and its effective use to suppress the overgrowth of pathogenic bacteria in Caenorhabditis elegans nematodes. Nanocontainers have been obtained using vacuum-facilitated loading of hydrophobic …

Antioxidant Properties of a Supercritical Fluid Extract of the Halophyte Mesembryanthemum nodiflorum L. from Sicilian Coasts: Nutraceutical and Cosme…
2020
The aim of this paper was to obtain different extracts from the aerial parts of Mesembryanthemum nodiflorum, comparing traditional extraction (using solvents with increasing polarity such as hexane, ethanol 80%, acetone 70% and water) with an eco-friendly technique (supercritical fluid extraction (SFE))
Screening of antioxidant potentials and bioactive properties of the extracts obtained from two Centaurea L. species (C. kroumirensis coss. and C. sic…
2020
Herbal medicines, dietary supplements, or infusions with health promoting effects can note strong consumer demand. Hence, researchers and scientists have been increasingly focusing on the promotion of medicinal plants. In this respect, the present study has the evaluation of the biological properties of different extracts (hexane, chloroform, methanol, ultrasonic, essential oil, and supercritical) obtained from two Centaurea species (C. kroumirensis (Coss.) and C. sicula L. subsp sicula) as purpose. Antioxidative activities were assessed by in vitro assays including total phenolic content, free radical scavenging assay and ferric ion reducing power. Among the fourteen extracts examined, the…
