Development of MOF@Polymer Composite Materials Through Bottom-Up Self-Assembly Techniques

MOF-based mixed matrix membranes (MMMs) are a promising new class of MOF/polymer composite materials. Currently, fabrication of MMMs is based on top-down methods with limited control over MOF positioning, integration, or morphology. This work focuses on the growth of well-defined one-dimensional (1-D) MOF nanostructures within the pores of a nanoporous polymer template, either commercially available or through the self-assembly of block co-polymers having tailor-designed surface functionalities. Studies were conducted using zeolitic imidazole framework-8 (ZIF-8) and polycarbonate track etched (PCTE) membranes, which demonstrated the feasibility of the outlined approach, and revealed the formation of distinct super- and nanostructures with controlled morphologies and orientations through variations in reactant concentrations and pore dimensions. A combination of electron microscopy and X-Ray techniques were used to fully characterize the new templated MMMs and identify the key factors that contribute to crystal growth and help determine the underlying mechanism for growth. Additionally, new polymeric materials were targeted and synthesized which will ultimately lead to the fabrication of designer block co-polymer asymmetric membranes for the in-situ growth of MOF

Technoethics

Este artículo intenta unir las ciencias y las humanidades para poder solucionar los problemas éticos que aparecen con las aplicaciones de la tecnología. Los códigos morales han sido creados por el hombre, pero para saber si algo es bueno o malo para la humanidad se necesitan estudios científicos de todo tipoThis article attempts to join Science and Art in an attempt to solve the ethical problems that appear with the applications of Technology. Moral codes have been created by men, but to know if something is good or bad for the Human race it is necessary to make scientific studies of all kind

Evaluation of technology and technology assessment

La tecnología no puede ser confundida con los abusos y mal usos de su utilización, para evitar esto se ha de hacer una evaluación de la tecnología. La previsión tecnológica sirve para revisar y modificar objetivos tecnológicos de tal manera que sean compatibles con el futuro logro, a continuación se debe hacer una guía de planificación, programación, control y evaluación que constituye la evaluación de la tecnología (Technology Assessment)Technology can not be confused with its abuse and wrongful use, to avoid this, it is necessary to evaluate technology. Technological provision helps us check and modify technological objectives in such a way that they will be compatible with future achievement, a planning, programming, control and evaluation guide, all of which constitutes an evaluation of technology, should then be drawn up (Technology Assessment

"El \uabPinocho\ubb de Salvador Mestres (Barcelona, 194-)".

In questo articolo si presenta l'analisi di un adattamento spagnolo di \u201cLe avventure di Pinocchio\u201d, realizzato negli anni '40 dall\u2019illustratore Salvador Mestres per la casa editrice Bruguera di Barcellona. L'analisi inizia con una revisione delle traduzioni e adattamenti spagnoli dell\u2019opera, segue con la presentazione della figura di Mestres e si conclude con l'analisi della sua versione: si identificano i cambiamenti nella macrostruttura del testo originale; si stabiliscono i parallelismi e differenze con la versione originale e la versione cinematografica della Disney; e si analizzano i processi di adattamento alla lingua e alla cultura di arrivo

Technological truth and Modern Empiricismo

En este trabajo se reflexiona sobre el concepto de verdad en el marco de 1a filosofía de la tecnología y se contraponen las posiciones de tendencias empiristas recientes -especialmente la formulada por van Fraasen- al realismo epistemológico como formas alternativas de desigual valo

Economics and systems: the institutionalist approach

El enfoque institucionalista trata de la aparición de nuevas ideas de control social como un contrapeso a la economía tradicional. Los institucionalistas buscan para una teoría de desarrollo manejable encarnado en ideas de reforma social. Como se revisaron las bases metodológicas y prevalecen las nociones teóricas del ofneoclasicismo y keynesianismo y cayeron al suelo, surgió una tendencia a la socialización del pensamiento económic
