A problem with viscoelastic mixtures: numerical analysis and computational experiments
(2021)
Article
Accés obertIn this paper, we study, from the numerical point of view, a dynamic problem involving a mixture of two viscoelastic solids. The mechanical problem is written as a system of two coupled partial differential equations. Its ... -
A type III thermoelastic problem with mixtures
(2021-06)
Article
Accés obertIn this work we study a thermoelastic problem involving binary mixtures. Type III thermal theory is considered for the modeling of the heat conduction. Existence, uniqueness and continuous dependence of solutions are proved ... -
Analysis of the thixotropic behavior and the deterioration process of bitumen in fatigue tests
(2015-12)
Article
Accés obertThe characterization of fatigue damage on bituminous materials under cyclic loading has been classically studied using tests and procedures previously developed for the characterization of metallic materials. However, these ... -

Challenges in synthesis and analysis of asymmetrically grafted cellulose nanocrystals via atom transfer radical polymerization
(2021-06-01)
Article
Accés obertWhen cellulose nanocrystals (CNCs) are isolated from cellulose microfibrils, the parallel arrangement of the cellulose chains in the crystalline domains is retained so that all reducing end-groups (REGs) point to one ... -
Convergence to steady-state and boundary layer profiles in a linear chromatography system
(2015-01-01)
Article
Accés restringit per política de l'editorialWe study the hyperbolic system of equations of the so-called linear transport model in a true moving bed chromatography device with four ports. By using methods based on a suitable energy functional we show that all solutions ... -
Customized fading scaffolds: strong polyorthoester networks via thiol–ene cross-linking for cytocompatible surface-eroding materials in 3D printing
(2021-04-12)
Article
Accés obertPolyorthoesters are a highly desirable class of cytocompatible materials that are able to rapidly surface-erode. Despite their promise, their mechanical weakness and complex synthesis have limited their processability and ... -
Hydrodynamic determination of the kinematic viscosity of waste brines
(American Chemical Society (ACS), 2019-12)
Article
Accés obertWastewater from a potash mine in the central region of Catalonia is transported by means of a collector that runs more than 100 km, spilling into the sea on the Catalan central coast. To analyze the hydraulics of this ... -
Molecular dynamic in binary mixtures and polymer blends with large difference in glass transition temperatures of the two components: A critical review
(2019-09-11)
Article
Accés obertThe dynamics in highly asymmetric mixtures with large difference in Tg of the two components are complex. At low values of the lower-Tg2 component only the a1-relaxation and its Tga1 were found together with a fast relaxation. ... -
Numerical study of the onset of thermosolutal convection in rotating spherical shells
(2012-06-01)
Article
Accés obertThe influence of an externally enforced compositional gradient on the onset of convection of a mixture of two components in a rotating fluid spherical shell is studied for Ekman numbers E = 10−3 and E = 10−6, Prandtl numbers ... -
Selective detection of dopamine combining multilayers of conducting polymers with gold nanoparticles
(2014-05-01)
Article
Accés restringit per política de l'editorialElectrodes based on the combination of three-layered films formed by two different conducting polymers and gold nanoparticles have been developed for the selective voltammetric determination of dopamine in mixtures with ... -
System efficiency analysis of dual interconnected bubbling fluidized bed reactors for solar fuel production
(Universidade do Minho, 2019-08-19)
Text en actes de congrés
Accés obertChemical looping syngas production is a two-step syngas fuel production process that produces CO and H 2 . The process is composed of two fluidized bed reactors (oxidation reaction and reduction reactor), oxygen carriers ...
