Hollow platinum-gold and palladium-gold nanoparticles: synthesis and characterization of composition-structure relationship
Springer Science and Business Media LLC - Tập 24 - Trang 1-15 - 2022
Gisella Liliana Lucero Lucas, Henry Romanus, Adriana Ispas, Andreas Bund
Hollow palladium-gold (PdAu) and platinum-gold (PtAu) alloy nanoparticles (NPs) were synthesized through galvanic replacement reactions. PdAu NPs denoted PdAu-99.99 and PdAu-98 were produced using palladium precursors with different purity degree: Na2PdCl4 ≥ 99.99% and Na2PdCl4 98%, respectively. The effect of the addition time of the gold palladium precursor solution on the size of the generated ...... hiện toàn bộ
PEGylation of SPIONs by polycondensation reactions: a new strategy to improve colloidal stability in biological media
Springer Science and Business Media LLC - Tập 15 - Trang 1-14 - 2013
Wesley Renato Viali, Eloiza da Silva Nunes, Caio Carvalho dos Santos, Sebastião William da Silva, Fermin Herrera Aragón, José Antonio Huamaní Coaquira, Paulo César Morais, Miguel Jafelicci
In this study, we report on a new route of PEGylation of superparamagnetic iron oxide nanoparticles (SPIONs) by polycondensation reaction with carboxylate groups. Structural and magnetic characterizations were performed by X-ray diffractometry (XRD), transmission electron microscopy (TEM), thermogravimetric analysis (TGA), and vibrating sample magnetometry (VSM). The XRD confirmed the spinel struc...... hiện toàn bộ

Electron beam-induced structural transformations of MoO3 and MoO3−x crystalline nanostructures
Springer Science and Business Media LLC - Tập 14 - Trang 1-9 - 2012
D. E. Diaz-Droguett, A. Zuñiga, G. Solorzano, V. M. Fuenzalida
Electron beam-induced damage and structural changes in MoO3 and MoO3−x single crystalline nanostructures were revealed by in situ transmission electron microscopy (TEM) examination (at 200 kV) after few minutes of concentrating the electron beam onto small areas (diameters between 25 and 200 nm) of the samples. The damage was evaluated recording TEM images, while the structural ch...... hiện toàn bộ

Effects of grain boundary width and crystallite size on conductivity and magnetic properties of magnetite nanoparticles
Springer Science and Business Media LLC - Tập 16 - Trang 1-12 - 2014
K. L. Lopez Maldonado, P. de la Presa, M. A. de la Rubia, P. Crespo, J. de Frutos, A. Hernando, J. A. Matutes Aquino, J. T. Elizalde Galindo
The structural, electrical, and magnetic properties of magnetite nanoparticles, with crystallite sizes 30, 40, and 50 nm, are studied. These crystallite sizes correspond to average particle sizes of 33, 87, and 90 nm, respectively, as determined by TEM. By HRTEM images, it is observed that grain boundary widths decrease as crystallite size increases. Electrical and microstructural properties are c...... hiện toàn bộ
Controlled synthesis and characterization of layered manganese oxide nanostructures with different morphologies
Springer Science and Business Media LLC - Tập 11 - Trang 1107-1115 - 2008
Naicai Xu, Zong-Huai Liu, Xiangrong Ma, Shanfeng Qiao, Jiaqi Yuan
Layered manganese oxide nanostructures with different morphologies, such as nanowire bundles, cotton agglomerates, and platelikes were successfully fabricated by a simple and template-free hydrothermal method based on a reaction of KMnO4 and KOH solutions with different concentrations. The obtained nanowire bundles were assembled by nanowires with diameters of 10 to 200 nm and lengths up to 5–10 μ...... hiện toàn bộ
