The thermodynamic properties and band gap energies were evaluated for six ortho- and peri-fused polycyclic aromatic hydrocarbons (PAHs): triphenylene; benzo­[a]­pyrene; benzo­[e]­pyrene; perylene; benzo­[ghi]­perylene; coronene. The standard molar enthalpies of formation in the crystalline state and the standard molar enthalpies of sublimation were measured by high precision combustion calorimetry and Knudsen effusion methodology, respectively. The combination of the molar enthalpies of formation in the crystalline state with the respective enthalpies of sublimation was used to evaluate the energetics of the progressive peri-fusion of the aromatic moieties from triphenylene to coronene aiming to investigate the hypothetical superaromaticity character of coronene. The linear trend of the enthalpy of formation in crystalline and gaseous phases in the series (from benzo­[e]­pyrene to coronene) is an irrefutable indication of a non-superaromaticity character of coronene. High accurate thermodynamic properties of sublimation (volatility, enthalpy, and entropy of sublimation) were derived by the measurement of vapor pressures as a function of temperature, using a Knudsen/quartz crystal effusion methodology. Furthermore, the π-electronic conjugation of these compounds was explored by evaluation of the optical band gaps along with this series of compounds. The morphology of perylene, benzo­[ghi]­perylene, and coronene thin films, deposited by physical vapor deposition onto transparent conductive oxide substrates (ITO and FTO), was used to analyze the nucleation and growth mechanisms. The morphologies observed were found to be related to the cohesive energy and entropy of the bulk.

In this study, a homogeneous thin film growth of pentacene onto indium tin oxide (ITO) coated glass surfaces is explored using a high‐resolution and reproducible vapor deposition methodology. Moreover, vacuum thermal evaporation of ionic liquids (ILs) ([C2C1im][NTf2] and [C2C1im][OTF]) onto ITO, gold/palladium (AuPd) and pentacene surfaces were performed. A greater wettability behavior of ILs is observed for surfaces containing AuPd. Sequential and simultaneous depositions of ILs and pentacene were explored. Simultaneous depositions lead to the formation of nanocomposites films, consisting of IL micro‐ and nanodroplets covered by pentacene layers. Plasma surface treatment was used to induce the ILs droplets coalescence and explore the dynamics and phase separation of the nanocomposites. The [C2C1im][OTF] droplets were found to be completely covered with pentacene, which suggests a great affinity between cation‐anion pairs and the aromatic moiety. Pentacene films and their nanocomposites with ILs exhibit a typical optical band gap of Egap=1.77 eV, indicating that the nanocomposite phase domains are large enough to behavior as the bulk.

Microdroplets and thin films of imidazolium-based ionic liquids (ILs) of different sizes and shapes were used as confining agents for the formation of high-quality perylene crystals by vapor deposition. The...

Las poblaciones ante la virulencia del COVID19 mostraron la pérdida de su bienestar y las opciones alimentarse adecuadamente para resistir al confinamiento, o para salvar vida pusieron en ejercicio a los conocimientos científicos de varios grupos de profesionales, que se encontraron ante un virus poco estudiado con una gran letalidad.  Para ello se realizó una investigación analítica eligiendo la literatura científica de aplicación del francés Quinton, quien había descubierto las propiedades del agua de mar, y de algunas plantas medicinales. Se realiza una investigación de campo, orientada a establecer los beneficios anticoagulantes del agua de mar en un consumo adecuado de 30 ml en las personas que alejadas de los fármacos acudieron a la misma como un recurso que mineralizó el cuerpo y sin saberlo al inició de la investigación evitó la coagulación de la sangre en personas que venían bebiendo agua de mar debidamente tratada. De esa manera, en forma inconsciente con los minerales que tenían en su cuerpo por la ingesta de agua de mar procesada, permitió que anticoagulantes naturales como el magnesio actuara como una barrera dentro de la cascada de coagulación, evitando que colapsen los pulmones por los componentes de la misma. La investigación tiene como objetivo establecer el aporte científico del conocimiento de la dosificación del agua de mar en el mejoramiento el bienestar y desarrollo de nuestros pueblos entrevistando a aquellos que la utilizaron para recoger información directa sobre sus beneficios orgánicos según su aplicación. Es un estudio cuantitativo y comparativo de las recomendaciones de la OMS se establecen las pautas mediante el proceso del método científico de observación, análisis, hipótesis y conclusiones. El análisis elige como tamaño de la muestra a 100 personas que se recuperaron luego de la administración del mar respaldado por un análisis de las historias clínicas y estudios de laboratorio luego de su aplicación. Entre los resultados está que el agua de mar ozonificada, en el 90% de la población que mostró ahogamiento a partir de la segunda semana de virulencia al administrarse agua de mar, mostró recuperación a las 72 horas y un restablecimiento progresivo. En el estudio físico de la sangre durante y después de la administración del agua de mar, se observaron cambios en la coloración de la sangre y en la capacidad coaguladora.     Populations in the face of the virulence of COVID19 showed the loss of their well-being and the options to eat properly to resist confinement, or to save life, put into practice the scientific knowledge of several groups of professionals, who were faced with a little-studied virus with a great lethality. For this, an analytical investigation was carried out choosing the scientific literature of the French Quinton, who had discovered the properties of seawater, and of some medicinal plants. A field investigation is carried out, aimed at establishing the anticoagulant benefits of seawater in an adequate consumption of 30 ml in people who, away from drugs, resorted to it as a resource that mineralized the body and without knowing it at the beginning of the research prevented blood clotting in people who had been drinking properly treated seawater. In this way, unconsciously with the minerals that they had in their body from the intake of processed seawater, it allowed natural anticoagulants such as magnesium to act as a barrier within the coagulation cascade, preventing the lungs from collapsing due to the components Of the same. The objective of the research is to establish the scientific contribution of the knowledge of seawater dosage in improving the well-being and development of our peoples by interviewing those who used it to collect direct information on its organic benefits according to its application. It is a quantitative and comparative study of the WHO recommendations, the guidelines are established through the process of the scientific method of observation, analysis, hypotheses and conclusions. The analysis chooses as the sample size 100 people who recovered after the administration of the sea supported by an analysis of medical records and laboratory studies after its application. Among the results is that ozonated seawater, in 90% of the population that showed drowning from the second week of virulence when seawater was administered, showed recovery at 72 hours and a progressive recovery. In the physical study of the blood during and after the administration of seawater, changes in the color of the blood and in the coagulant capacity were observed.
