Polytetrafluoroethylene Films in Rigid Polyurethane Foams' Dielectric Permittivity Measurements with a One-Side Access Capacitive Sensor.
2021
As a non-metallic composite material, widely applied in industry, rigid polyurethane (PUR) foams require knowledge of their dielectric properties. In experimental determination of PUR foams’ dielectric properties protection of one-side capacitive sensor’s active area from adverse effects caused by the PUR foams’ test objects has to be ensured. In the given study, the impact of polytetrafluoroethylene (PTFE) films, thickness 0.20 mm and 0.04 mm, in covering or simulated coating the active area of one-side access capacitive sensor’ electrodes on the experimentally determined true dielectric permittivity spectra of rigid PUR foams is estimated. Penetration depth of the low frequency excitation…
Recent Advances on the Halo- and Cyano-Trifluoromethylation of Alkenes and Alkynes
2021
Incorporation of fluorine into organic molecules is a well-established strategy in the design of advanced materials, agrochemicals, and pharmaceuticals. Among numerous modern synthetic approaches, functionalization of unsaturated bonds with simultaneous addition of trifluoromethyl group along with other substituents is currently one of the most attractive methods undergoing wide-ranging development. In this review article, we discuss the most significant contributions made in this area during the last decade (2012−2021). The reactions reviewed in this work include chloro-, bromo-, iodo-, fluoro- and cyano-trifluoromethylation of alkenes and alkynes.

La intervención de Cenicienta en la construcción de las pirámides. Un tipo iconográfico en la primera serie litográfica de las Maravillas del mundo
2020
En el siglo XVI se realiza la primera serie de litografías de las Maravillas del mundo. En ellas se representan las arquitecturas más emblemáticas de la Antigüedad. Pero en la relativa a las pirámides de Egipto se esconde un tipo iconográfico que pasa desapercibido si no se conocen las fuentes historiográficas griegas. Alude a Rhodopis, la primera Cenicienta, y su papel clave en la construcción de las pirámides. Maarten Van Heemskerck y Philips Galle nos guían hasta los historiadores clásicos Heródoto y Estrabón a través de la iconografía, para hacernos conocedores de la historia de la joven Rhodopis, una joven griega cuyo zapato toma un águila y deja caer en el regazo del faraón egipcio. D…
Prevention of 7-Ketocholesterol-Induced Overproduction of Reactive Oxygen Species, Mitochondrial Dysfunction and Cell Death with Major Nutrients (Pol…
2020
The brain, which is a cholesterol-rich organ, can be subject to oxidative stress in a variety of pathophysiological conditions, age-related diseases and some rare pathologies. This can lead to the formation of 7-ketocholesterol (7KC), a toxic derivative of cholesterol mainly produced by auto-oxidation. So, preventing the neuronal toxicity of 7KC is an important issue to avoid brain damage. As there are numerous data in favor of the prevention of neurodegeneration by the Mediterranean diet, this study aimed to evaluate the potential of a series of polyphenols (resveratrol, RSV
