Journal ArticleDOI
Rheological and volumetric properties of TiO2-ethylene glycol nanofluids
David Cabaleiro,María José Pastoriza-Gallego,Carlos Gracia-Fernández,Manuel M. Piñeiro,Luis Lugo +4 more
TL;DR: The rheological behavior was determined for both nanofluids at nanoparticle mass concentrations up to 25%, including flow curves and frequency-dependent storage and loss moduli, using a cone-plate rotational rheometer.
Journal ArticleDOI
Near room temperature dielectric transition in the perovskite formate framework [(CH3)2NH2][Mg(HCOO)3].
Breogán Pato-Doldán,Manuel Sánchez-Andújar,L. C. Gómez-Aguirre,S. Yáñez-Vilar,Jorge López-Beceiro,Carlos Gracia-Fernández,A. A. Haghighirad,F. Ritter,Socorro Castro-García,María Antonia Señarís-Rodríguez +9 more
TL;DR: This is the highest Tt reported so far for a perovskite-like formate that is thus a promising candidate to display electric order very close to room temperature.
Journal ArticleDOI
Specific heat of metal oxide nanofluids at high concentrations for heat transfer
TL;DR: In this paper, isobaric specific heat capacity measurements were performed for five different nanofluid sets designed as dispersions up to 15% mass concentrations of MgO, ZnO, and ZrO 2 in pure ethylene glycol as well as ZnOs, ZOs and ZRs in an ethanol glycol+water mixture at 50:50% in volume.
Journal ArticleDOI
Comparative study of the dynamic glass transition temperature by DMA and TMDSC
Carlos Gracia-Fernández,S. Gómez-Barreiro,Jorge López-Beceiro,J. Tarrío Saavedra,Salvador Naya,Ramón Artiaga +5 more
TL;DR: In this article, the same frequency and temperature using quasi-isothermal conditions in both instruments were compared with three different polymer samples and it was found that when choosing a suitable response parameter, i.e. the phase angle, the dynamic glass transition temperature values obtained by both methods are practically the same.
Journal ArticleDOI
Use of rheology, dielectric analysis and differential scanning calorimetry for gel time determination of a thermoset
TL;DR: In this article, the authors compared the results obtained by rheometry and dielectric analysis to those obtained using the Flory equation and found a reasonable agreement between the two techniques that lead to gel conversion values very close to the ones obtained using DEA.
