Electrocatalysis of neurotransmitter catecholamines by 2,4,6-triphenylpyrylium ion immobilized inside zeolite Y supercages
1999
2,4,6-Triphenylpyrylium ions entrapped inside the supercages of Y zeolite exert a remarkable catalytic effect toward the electrochemical oxidation of dopamine and norepinephrine (neurotrasmitter catecholamines) in neutral aqueous media. Domenech Carbo, Antonio, Antonio.Domenech@uv.es
Water dissociation and water-gas shift energetics on MgO, MgO/Ag and Au/MgO/Ag surfaces
2011
Water dissociation and the energetics of the WGS reaction on a bulk MgO, an Ag supported MgO thin film and Au/MgO/Ag surfaces is studied based on the density functional theory. The literature results for water splitting on MgO and MgO/Ag surfaces with a step type defect are repeated and further analysis on the origin of the energetically favored dissociative water adsorption are made. The reactivity towards water dissociation on the stepped MgO and MgO/Ag surfaces is attributed to four contributing factors: 1. The change in the interlayer distance of the surface in dissociative adsorption is diminished on the stepped surfaces compared to the flat surfaces. On the flat surfaces the dissociat…
Hybrid materials based on conductive polymers for energy harvesting
2022
Uno de los objetivos de la Organización de las Naciones Unidas (ONU) para el Desarrollo Sostenible 2030 es obtener energía asequible y no contaminante. Por este motivo, se recomiendan encarecidamente las mejoras en la eficiencia energética y las fuentes de energía verde como soluciones óptimas para reducir las emisiones de dióxido de carbono y, por tanto, reducir la huella de carbono de nuestra sociedad. Las emisiones de carbono se han cuadriplicado desde 1950 y actualmente contribuyen en torno al 80 % de las emisiones de gases de efecto invernadero. Como resultado de este cambio, el clima global sufre cambios en las tendencias globales de lluvia y una reducción en los casquetes polares. Co…
Reflections of Hope and Anxiety in Audience Responses to Three Environmental Films
2023
This article discusses the results of a reception study of three environmental films with a focus on emotional reactions and the films’ influence on the respondents’ environmental awareness. The short experimental film Valtakunnat/Realms (Finland, 2018) envisions post-human life, and the potential destruction that the planet is being driven towards. To Teach a Bird to Fly (Finland, 2020), a short documentary fiction film about a woman raising critically endangered birds, imagines a future where the effects of climate change have been reversed. The documentary film The Biggest Little Farm (USA, 2018) follows a couple who buy a barren farm with the aim of restoring its biodiversity. Through t…
Control of Growth and Persistence of Listeria monocytogenes and β-Lactam-Resistant Escherichia coli by Thymol in Food Processing Settings
2020
The main objective of this study was to evaluate the efficacy of thymol in controlling environmental contamination in food processing facilities. The effect of thymol was tested as an agent to prevent planktonic and bacterial biofilm growth of twenty-five Listeria monocytogenes isolates from a variety of foods and five Escherichia coli isolates from a farm. The E. coli isolates were positive for extended spectrum &beta
Eumelanin Coating of Silica Aerogel by Supercritical Carbon Dioxide Deposition of a 5,6-Dihydroxyindole Thin Film
2018
Eumelanin integration in silica aerogel (SA) was achieved via supercritical adsorption of 5,6-dyhydroxyindole (DHI) from CO2. Notably, after the supercritical treatment, DHI evolved towards spontaneous polymerization, which resulted in uniform pigment development over the SA. The new material was characterized for its morphological and physicochemical properties, disclosing the formation of a eumelanin-like coating, as confirmed by UV&ndash
Electron Irradiation Effects on Single‐Layer MoS 2 Obtained by Gold‐Assisted Exfoliation
2022
International audience; Mechanical exfoliation assisted by gold is applied to obtain good quality large lateral size single-layer MoS2. The effects of 2.5 MeV electron irradiation are investigated at room temperature on structural and electronic features by Raman and microluminescence spectroscopy. The exciton recombination emission in the direct bandgap of single-layer MoS2 is affected during irradiation starting from the minimum explored dose of 1 kGy. At higher doses, Raman bands show no relevant modifications whereas the exciton emission is quenched, suggesting that irradiation-induced point defects affect exciton dynamics.
Filmowe wyobrażenia klasztoru: realizm, magia, pragnienia
2016
Monasteries of various religious and spiritual traditions are an interesting subject of numerous films: among them there are portraits of authentic communities (Die grosse Stille, 2004), films on historic characters (Francesco, giullare di Dio, 1948), dramas (Philomena, 2013), horrors (Devils, 1971), comedies (Sister Act, 1992), even erotic films. The paper analyzes three chosen films: Des Hommes et des Dieux (2010), Jasminum (2006) and Ostrov (2006). Their directors present different approaches to the religious communities on the screen: while the French film is an attentive, almost documentary reconstruction of the last months of the Thibirine monks, Jasminum is a fantasy, where the relig…
