Low temperature synthesis of nanocrystalline Y3Al5O12 (YAG) and Ce-doped Y3Al5O12via different sol–gel methods
TL;DR: In this paper, Nanocrystalline yttrium aluminium garnet (YAG, Y3Al5O12) and Ce-doped YAG ceramics were synthesized by two "soft chemistry" sol-gel processes using (i) mixtures of ーテinorganic salts or oxides and (ii) mixture of alkoxides of the respective elements, in the first approach the metal ions, generated by dissolving metal oxides or nitrates in acetic acid and/or water, were complexed by ethylene glycol to obtain the prec

Size-Dependent Photoconductance in SnO2 Nanowires
Journal ArticleDOI
Water-soluble superparamagnetic magnetite nanoparticles with biocompatible coating for enhanced magnetic resonance imaging.
Lisong Xiao,Jiangtian Li,Dermot F. Brougham,Eoin K. Fox,Neus Feliu,Alexey Bushmelev,Annette M. Schmidt,Natascha Mertens,Fabian Kiessling,Martin Valldor,Bengt Fadeel,Sanjay Mathur +11 more
TL;DR: The cell tests performed with primary human immune-competent cells confirmed the excellent biocompatibility of USIRONs and the potential of the DHAA-Fe(3)O(4) nanoparticles as negative contrast agents for MRI with optimal hydrodynamic size for extended blood circulation times was confirmed.
Journal ArticleDOI
Ultralow power consumption gas sensors based on self-heated individual nanowires
Joan Daniel Prades,R. Jimenez-Diaz,Francisco Hernandez-Ramirez,Sven Barth,Albert Cirera,Albert Romano-Rodriguez,Sanjay Mathur,Joan Ramon Morante +7 more
TL;DR: In this paper, the sensing capabilities of self-heated individual SnO2 nanowires toward NO2 are presented, and these proof-of-concept systems exhibited responses nearly identical to those obtained with integrated microheaters.
