The structural analysis of nylon/graphene oxide (NY/GO) and polyetherblockamide/ trisilinolphenyl-polyhederal oligomeric silsesquioxane (PEBA/t-POSS) composites were performed using high-resolution spectral domain optical coherence tomography (SD-OCT). This optical technology revealed both cross-sectional, as well as sub-layer depth information of sample. The non-destructive real-time imaging d...

Resumo Este estudo busca refletir sobre a relação entre mediação de leitura imagem e educação estética, cuja metodologia é Pesquisa Educacional Baseada em Arte (Peba). Os dados foram produzidos um encontro para crianças 6 7 anos idade, com participação do artista Marcelo Urizar. O baseia-se nas discussões Martins cultural, Duarte Schiller estética Heidegger Larrosa o conceito experiência. Entre...

Para la resolución de problemas en matemáticas es un prerrequisito comprensión los planteamientos ya que a partir este conocimiento el estudiante puede lograr resultados positivos. Esta investigación tuvo como objetivo determinar relación entre nivel lectora y aritméticos, estudiantes del quinto curso primaria. Se enmarcó paradigma cuantitativo, con alcance descriptivo correlacional utilizando ...

Poly (amide-6-b-ethylene oxide)/Zinc Oxide (PEBA/ZnO) mixed matrix membranes were fabricated using ethanol/water as solvent by solvent casting method. The concentration of ZnO in membrane was set to 0.1 wt.% and the synthesized membranes were characterized by AFM and FTIR. Effects of ZnO nanoparticle on CO2, CH4 and N2 permeabilities, and CO2/N2<...

Poly(ether-block-amide) (PEBA, commercialized as Pebax) copolymer membranes show a highly promising platform for preparing high-performance CO2 capture from process streams containing CH4 and N2. Pebax combines high affinity with the desired mechanical strength polymeric thanks to its flexible polyether segment hard polyamide block, respectively. Furthermore, researchers have been improving per...
