Encapsulation of hydrophilic and lipophilized catechin into nanoparticles through emulsion electrospraying
2017
In this work, we investigated the potential of emulsion electrospraying that contained bacterial cellulose and proteins for the encapsulation of epigallocatechin gallate (EGCG). Specifically, two different catechins, hydrophilic (H-EGCG) or lipophilized (L-EGCG), were encapsulated either on the aqueous or the oily phase of the emulsions in order to compare the antioxidants’ stability. Emulsion properties in terms of stability, droplet size, bulk and interfacial viscosity were studied combined with the evaluation of the properties of the produced particles, namely the morphology and size of the particles, the encapsulation efficiency (EE) of catechin and the stability of the EGCG within the …
Antibacterial biopolymeric foams: Structure–property relationship and carvacrol release kinetics
2019
Abstract In this work, the feasibility of antibacterial biopolymeric foams containing carvacrol (CRV) for potential food packaging applications was investigated. Sodium bicarbonate (SB) was chosen as foaming agent and a commercial biodegradable polymer, Mater-Bi® (MB), as a matrix. MB/SB and MB/SB/CRV systems were prepared by melt mixing and the foaming process was conducted in a laboratory press. The influence of foaming agent and antibacterial additive content was investigated. The foamed samples were characterized through morphological analysis, mechanical tests and measurements of CRV release kinetics. Moreover, a mathematical model, i.e. power law model, was used to fit the release dat…
Blackwood's Magazine - "Nodier's Promenade"
2013
We have translated and annotated an extended review from "Blackwood's Edinburgh Magazine" reporting on the publication, in English translation, of "Promenade de Dieppe aux montagnes d'Écosse" by Charles Nodier ("Promenade from Dieppe to the Mountains of Scotland", Edinburg, Blackwood, London, Cadell, 1822). The reference of the original article is as follows: "Nodier's Promenade", Blackwood's Edinburgh Magazine", march 1822, vol. XI (January - June 1822).
Comparison of thermal‐ and photo‐polymerization of lauryl methacrylate monolithic columns for CEC
2009
Lauryl methacrylate-based (LMA) monolithic columns for CEC, prepared using either thermal initiation or by UV-irradiation in the presence of AIBN have been compared. Thermal polymerization was carried out at 70 degrees C for 20 h. For UV initiation, the effects of the time exposure to UV light and irradiation energy were investigated. For each initiation process, the influence of composition of porogenic solvent (1,4-butanediol/1-propanol ratio) on the physical and electrochromatographic properties of the resulting monoliths was also evaluated. Photochemically lauryl methacrylate stationary phases initiated showed higher permeabilities and better efficiencies than those prepared by thermal …
Fluorination of Cu(001) Surface by C60F48 Molecule Adsorption
2019
Copper surface functionalization by defluorination of C60F48 molecules with submonolayer and monolayer coverages on the Cu(001) crystal is studied by X-ray photoelectron spectroscopy. At room tempe...
Características y visibilidad de las revistas españolas de ciencias de la salud en bases de datos
2015
Se describen las características de 207 revistas españolas de ciencias de la salud activas en 2014 y su visibilidad en seis bases de datos biomédicas y multidisciplinares. Scopus e Ibecs son las bases de datos que mayor número de revistas cubren, y Medline y WoS las que menos. La disciplina mejor representada es medicina, seguida de psicología, enfermería y farmacia. Se observa la práctica ausencia de revistas editadas exclusivamente en papel, la existencia de revistas publicadas en inglés, el aumento de versiones bilingües español-inglés y el acceso gratuito a los contenidos. El artículo incorpora el censo de revistas, que puede servir de referencia para los investigadores para selecciona…
Strategies of Eliciting Young People’s Affective and Quick Participation in a Youth Magazine’s Instagram Community
2022
Traditional media have merged with social media and pursue to produce engaging content and form relationships with online audiences. At the same time, social media has allowed young people a venue to practice their basic needs of interaction, identity, and self-expression, and provides communities of shared issues and social/political aspirations. By analysing the Instagram post caption data of the largest Finnish (girls’) youth magazine, this case study investigated what posting strategies used by the magazine elicited youth participation, and how do the strategies and participation align with young people’s media and online communication preferences. The study found the magazine to use va…
Topics and Argentine and Latin American Authors in Publishing Projects of the Galician Exiled in Argentina during the 40s
2016
En el contexto de la época de oro de la industria editorial argentina, un grupo de exiliados de ascendencia gallega desempeñó un papel destacado a través de la edición de revistas culturales y de colecciones de libros: De Mar a Mar y Correo Literario, Buen Aire, Mar Dulce, Paloma y Botella al Mar. El presente trabajo analiza el lugar que ocuparon los temas y los autores latinoamericanos –y, especialmente, argentinos– en esos proyectos editoriales, teniendo en cuenta las relaciones entre los exiliados y el campo cultural local.
Bilayer biodegradable films prepared by co-extrusion film blowing: Mechanical performance, release kinetics of an antimicrobial agent and hydrolytic …
2020
Abstract Bilayer biodegradable, eco-friendly films were prepared by co-extrusion film blowing, coupling polylactic acid (PLA) and Bio-flex ® (BIO). Furthermore, in the PLA layer, carvacrol (CRV) was added as a natural antimicrobial additive, whereas a nanoclay (D72T) was integrated to protect CRV from volatilization and to modulate release. The materials were analyzed by morphological, chemical-physical, mechanical testing. Furthermore, CRV release and degradation tests were performed. The results pointed out that coupling the two matrices allows gathering the stiffness of PLA with the ductility of BIO. Furthermore, the interlayer adhesion is promoted by CRV. D72T exerts a key-role in avoid…
The voice of a heterodox authority on love in the First Francoism. Amparo Rivelles’ sentimental advice columns
2021
Entre 1948 y 1952, el semanario cinematográfico Primer plano publicó un consultorio sentimental firmado por la actriz Amparo Rivelles. La estrella española más popular del momento se convertía así en consejera sobre la moral, el noviazgo y los usos amorosos entre los jóvenes; una cuestión que el Régimen consideraba como una pieza fundamental en la regulación de las relaciones de género. Se trata de un consultorio singular, alejado de la gravedad, el dramatismo y la grandilocuencia de otros, surgidos en diversos medios periodísticos a raíz de la buena acogida de público que estas secciones gozaron durante aquellos años. El presente artículo analiza las implicaciones de unos textos en los que…
