Journal ArticleDOI
Synthesis and characterization of Fe3O4 nanoparticles coated with fucan polysaccharides
V. A. J. Silva,P. L. Andrade,M. P. C. Silva,Luis De Los Santos Valladares,Luis De Los Santos Valladares,J. Albino Aguiar +5 more
TL;DR: In this paper, the preparation of fucan-coated magnetite (Fe3O4) nanoparticles by the co-precipitation method was reported, which showed quasi-spherical morphology with mean sizes around 10nm.
Journal ArticleDOI
Crystallization and electrical resistivity of Cu2O and CuO obtained by thermal oxidation of Cu thin films on SiO2/Si substrates
L. De Los Santos Valladares,L. De Los Santos Valladares,L. De Los Santos Valladares,D. Hurtado Salinas,D. Hurtado Salinas,A. Bustamante Domínguez,D. Acosta Najarro,Saiful I. Khondaker,T. Mitrelias,Crispin H. W. Barnes,J. Albino Aguiar,Yutaka Majima +11 more
TL;DR: In this paper, the authors studied the electrical resistivity of the formed oxides in a Cu/SiO2/Si thin film after thermal oxidation by ex-situ annealing at different temperatures up to 1000°C.
Journal ArticleDOI
Screening of pair fluctuations in superconductors with coupled shallow and deep bands: A route to higher-temperature superconductivity
TL;DR: In this article, a coexistence of a shallow carrier band with strong pairing and a deep band with weak pairing, together with the Josephson-like pair transfer between the bands to couple the two condensates, realizes an optimal multicomponent superconductivity regime.
Journal ArticleDOI
Superconductivity between standard types: Multiband versus single-band materials
Alexei Vagov,A. A. Shanenko,Milorad V. Milošević,Vollrath M. Axt,V. M. Vinokur,J. Albino Aguiar,François M. Peeters +6 more
TL;DR: In this paper, the authors show that the same picture of the two standard types with the transitional domain in between applies also to multiband superconductors, such as recently discovered borides and iron-based materials, can belong to the intertype regime.
Journal ArticleDOI
Superconducting properties of a parallelepiped mesoscopic superconductor: A comparative study between the 2D and 3D Ginzburg–Landau models
TL;DR: In this paper, the authors theoretically investigate the local magnetic field, order parameter and supercurrent profiles of a parallelepiped mesoscopic superconductor submersed in an applied magnetic field; this same geometry with a pillar on its top surface is also considered.
