FeN4 active sites generated on dipyridylpyridazine functionalized reduced graphene oxide for high-performance air electrode in a Zn-air battery

The growing global electricity demand requires the development of cost-effective energy conversion and storage systems, integrating inexpensive, eco-friendly, and high-efficiency catalysts. Oxygen reduction reaction (ORR) is considered crucial process to achieve high-power-density fuel cells and Zn-air batteries (ZABs). The latter have attracted the attention of scientific community due to its high theoretical energy density, reliable safety and low-cost. However, several limitations must be overcome, designing ORR catalysts thought versatile and economical synthetic routes. In this sense, the non-noble iron–nitrogen-carbon materials (Fesingle bondNsingle bondC) have been reported as the most potential candidates for attaining superior activity toward ORR in substitution of the high-priced commercial Pt-C catalysts. Herein, Diels-Alder surface adducts based on dipyridylpyridazine units have been created along 2D surface of reduced graphene oxide (rGO) nanosheets for the controlled generation of FeN4 active sites at the edges through successive solvent-free mechanochemical reactions and an additional thermal treatment. The optimized catalyst provided high content of pyridinic-N, graphitic-N and Fe2+ species, contributing to the excellent activity delivered as electrocatalyst for ORR processes. In addition, a flooded ZAB assembled with this material as cathodic/air electrode exhibited excellent specific capacities of 4.94 and 2.77 A·h·g−1 at -1 and -5 mA, respectively, improving the catalytic performance obtained for the 10 wt% Pt-C benchmark electrocatalyst

APLICACIÓN DE MATERIALES DIDÁCTICOS SUSTENTADOS EN EL MÉTODO FÓNICO-ANALÍTICO-SINTÉTICO PARA DESARROLLAR LA LECTO-ESCRITURA EN ESTUDIANTES DE EDUCACIÓN GENERAL BÁSICA

El proyecto ejecutado consistió en la aplicación de materiales didácticos sustentados en el método fónico-analítico-sintético para el desarrollo de la lectoescritura en estudiantes de tercer año de Educación General Básica. Este proyecto tiene como finalidad mejorar la adquisición de la lectoescritura aplicándolo a inicios del año lectivo para reforzar el aprendizaje adquirido en los años anteriores. Al inicio se efectuó una encuesta dirigida a los docentes de la institución de los grados correspondientes, luego se realizó una observación directa a los estudiantes que permitió conocer el nivel de desarrollo cognitivo y grafológico en la lectoescritura. Una vez tabulado los datos obtenidos en la presente investigación se realizó la aplicación de los materiales didácticos apropiados para conseguir el objetivo planteado. Los materiales seleccionados se sustentan en el método fónico-analítico-sintético y se aplicaron con su respectiva planificación y un instrumento de control para verificar el progreso. Finalmente los resultados que se obtuvieron al culminar la ejecución del proyecto fueron satisfactorios, verificados a partir de la contrastación de los indicadores en el antes y el después de la intervención y comparado con otro grupo en el que no se aplicó los materiales, lo que demostró que mediante la aplicación de los materiales didácticos los estudiantes de tercer año de Educación General Básica lograron desarrollar las habilidades de la lectoescritura.

APPLICATION OF SUSTAINED DIDACTIC MATERIALS IN THE AUDIO-ANALYTIC-SYNTHETIC METHOD TO DEVELOP THE LECTURE-WRITING IN BASIC GENERAL EDUCATION STUDENTS ABSTRACT The project was executed in the application of teaching materials for literacy development in the third year students of General Basic Education. At the beginning a survey of teachers in a institution of the corresponding degrees was made after direct observation of the students was performed and an observation guide that was used to determine the level of cognitive development and literacy handwriting was developed. Once tabulated data obtained in this investigation that appropriate techniques are performed to achieve the objective. Selected techniques were applied to their respective planning and control instrument to check progress. Finally the results obtained on completion of the project implementation were satisfactory because they showed that by applying the teaching materials students of third year of General Basic Education succeeded in developing literacy skills.

Plan de contingencia para los servicios de medicina intensiva frente a la pandemia COVID-19

In January 2020, the Chinese authorities identified a new virus of the Coronaviridae family as the cause of several cases of pneumonia of unknown aetiology. The outbreak was initially confined to Wuhan City, but then spread outside Chinese borders. On 31 January 2020, the first case was declared in Spain. On 11 March 2020, The World Health Organization (WHO) declared the coronavirus outbreak a pandemic. On 16 March 2020, there were 139 countries affected. In this situation, the Scientific Societies SEMICYUC and SEEIUC, have decided to draw up this Contingency Plan to guide the response of the Intensive Care Services. The objectives of this plan are to estimate the magnitude of the problem and identify the necessary human and material resources. This is to provide the Spanish Intensive Medicine Services with a tool to programme optimal response strategies
