16 p, 190.5 KB Synthesis and optical characterization of Er-doped bismuth titanate nanoparticles grown by sol-gel hydrothermal method / Fuentes, Sandra (Centro para el Desarrollo de la Nanociencia y la Nanotecnología (Chile)) ; Muñoz, Pamela (Universidad Católica del Norte) ; Llanos, Jaime (Universidad Católica del Norte) ; Vega, Mauricio (Universidad Católica del Norte) ; Martin, Inocencio R. (Universidad de La Laguna) ; Chávez Ángel, Emigdio (Institut Català de Nanociència i Nanotecnologia)
The Er-doped bismuth titanate (BiTiO, BIT) nanoparticles were synthesized by a combined sol-gel and hydrothermal method under a partial oxygen pressure of 30 bar. The composition and morphology were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and Raman scattering. [...]

29 p, 1.5 MB Graphene triggered enhancement in visible-light active photocatalysis as well as in energy storage capacity of (CFO)1-x(GNPs)x nanocomposites / Israr, Muhammad (Institut Català de Nanociència i Nanotecnologia) ; Iqbal, Javed (Quaid-i-Azam University. Department of Physics) ; Arshad, Aqsa (International Islamic University. Department of Physics) ; Rani, Maria (Quaid-i-Azam University. Department of Physics) ; Gómez-Romero, Pedro 1959- (Institut Català de Nanociència i Nanotecnologia) ; Benages Vilau, Raúl (Institut Català de Nanociència i Nanotecnologia)
Cobalt ferrite-graphene nanoplatelets ((CFO)(GNPs)) nanocomposites are promising for efficient photocatalysis and high-performance supercapacitors. Multifunctional (CFO)(GNPs) nanocomposites prepared via facile chemical method have been investigated for their physio-chemical characteristics like crystal structure, morphology, chemical composition, optical properties, infrared vibrational modes, photocatalytic and supercapacitor applications. [...]

10 p, 1.0 MB Electrochemically synthesized mesoporous thin films of ZnO for highly efficient dye sensitized solar cells / Lima, F. Anderson S. (Institut Català de Nanociència i Nanotecnologia) ; Vasconcelos, Igor F. (Universidade Federal Do Ceará. Departamento de Engenharia Metalúrgica e de Materiais (Brazil)) ; Lira-Cantu, Monica (Institut Català de Nanociència i Nanotecnologia)
Abstract In this work, nanostructured thin films of ZnO were electrochemically grown on FTO substrates. The morphology was tuned by modifying the synthesis parameters. The synthesis was carried out by applying Zn(NO<inf>3</inf>)·6H<inf>2</inf>O as the sole component of the aqueous electrolyte, avoiding the use of capping agents. [...]

22 p, 322.6 KB Ultraviolet pulsed laser crystallization of Ba0.8Sr0.2TiO3 films on LaNiO3-coated silicon substrates / Queraltó López, Albert (Institut de Ciència de Materials de Barcelona) ; Pérez del Pino, Ángel (Institut de Ciència de Materials de Barcelona) ; De La Mata, Maria (Institut Català de Nanociència i Nanotecnologia) ; Tristany, Mar (Institut de Ciència de Materials de Barcelona) ; Obradors, Xavier (Institut de Ciència de Materials de Barcelona) ; Puig i Molina, Mª Teresa (Institut de Ciència de Materials de Barcelona) ; Trolier-McKinstry, Susan (Pennsylvania State University)
In this work, BaSrTiO (BST) films on LaNiO-buffered SiO/Si (LNO/SiO/Si) substrates were crystallized by pulsed laser irradiation. Solution-derived amorphous barium-strontium-titanate precursor layers were crystallized with a KrF excimer laser in oxygen ambient at fluences ranging from 50 to 75 mJ cm. [...]
