Effect of Molecular Flexibility on the Nematic-to-Isotropic Phase Transition for Highly Biaxial Molecular Non-Symmetric Liquid Crystal Dimers
(MDPI, 2011-10)In this work, a study of the nematic (N)-isotropic (I) phase transition has been made in a series of odd non-symmetric liquid crystal dimers, the alpha-(4-cyanobiphenyl-4'-yloxy)-omega-(1-pyrenimine-benzylidene-4'-oxy) ... -
Efficient Synthesis of Single-Chain Polymer Nanoparticles via Amide Formation
Sánchez Sánchez, Ana Belén; Pomposo Alonso, José Adolfo (Hindawi Publishing, 2015)
Single-chain technology (SCT) allows the transformation of individual polymer chains to folded/collapsed unimolecular soft nanoparticles. In this work we contribute to the enlargement of the SCT toolbox by demonstrating ... -
Hole-Phonon Relaxation and Photocatalytic Properties of Titanium Dioxide and Zinc Oxide: First-Principles Approach
(Hindawi Publishing, 2014)First-principles calculations for the temporal characteristics of hole-phonon relaxation in the valence band of titanium dioxide and zinc oxide have been performed. A first-principles method for the calculations of the ... -
In Vitro Degradation of Poly(caprolactone)/nHA Composites
(Hindawi Publishing, 2014)The degradation behavior and mechanical properties of polycaprolactone/nanohydroxyapatite composite scaffolds are studied in phosphate buffered solution (PBS), at 37 degrees C, over 16 weeks. Under scanning electron ... -
Influence of Humidity on Fiber Bragg Grating Sensors
Montero, Ander; Aldabaldetreku Etxeberria, Gotzon; Durana Apaolaza, Gaizka ; Jorge, Iagoba; Sáez de Ocáriz, Idurre; (Hindawi, 2014-01)
We demonstrate the influence of the relative humidity (RH) on the wavelength of fiber Bragg grating sensors (FBGS), performing tests with five FBGS at different humidity and temperature conditions. These tests were performed ... -
Manipulation of domain wall dynamics in amorphous microwires through the magnetoelastic anisotropy
Zhukov Egorova, Arkady Pavlovich; Blanco Aranguren, Juan María ; ; ; Zhukova Zhukova, Valentina (Springer, 2012-04)
We studied the effect of magnetoelastic anisotropy on domain wall (DW) dynamics and remagnetization process of magnetically bistable Fe-Co-rich microwires with metallic nucleus diameters (from 1.4 to 22 mu m). We manipulated ... -
Nanostructured giant magneto-impedance multilayers deposited onto flexible substrates for low pressure sensing
(Springer, 2012-04)Nanostructured FeNi-based multilayers are very suitable for use as magnetic sensors using the giant magneto-impedance effect. New fields of application can be opened with these materials deposited onto flexible substrates. ... -
