Avaliação da aderência entre barras finas de aço e concretos de diferentes classes de resistência

Danielle de Maria Paiva Alves Fernandes2018-03-06LA Referencia (Red Federada de Repositorios Institucionales de Publicaciones Científicas)

A aderência aço-concreto é um mecanismo de interação que possibilita a transferência de esforços das barras de aço para o concreto. Ela se mostra como uma das propriedades fundamentais em elementos de concreto armado. Para avaliação da aderência aço-concreto, os ensaios mais utilizados na literatura são: ensaios de ar…

Ionic Motion in Solid Electrolytes: A Solid State NMR Study of Sodium and Lithium in β-Alumina

Albert J. Highe2018-03-06CaltechTHESIS (California Institute of Technology)

Solid state NMR techniques have been used as a microscopic probe of the structural and dynamical properties of the mobile cations in the solid electrolyte β-alumina. The first order quadrupole shifts in the (±3/2 ↔ ±1/2) transitions in the spin 3/2 nuclei sodium and lithium have allowed the electric field gradients (E…
