The water soluble tris-aqua complex [Gd(dhqN-SO3)(H2O)3](3-) based on a hexadentate hydroxyquinoline ligand shows high thermodynamic stability and high relaxivity (12.54 mM(-1) s(-1) at 1.2 T). Its non-covalent confinement in 25 nm silica nanoparticles prevents transmetallation and endogenous anion binding and leads to higher relaxivity over a wide range of magnetic fields.

Tin dioxide (SnO2) possesses great potential as an anode material for lithium-ion batteries (LIBs) owing to its high theoretical specific capacity. However, the irreversible conversion of Sn SnO2 and enormous volume variation during charge/discharge process limit battery energy storage performance. In this study, ultrafine NiO nanoparticles (NPs) decorated on a three-dimensionally (3D) intercon...

Tin oxide nanoparticles were synthesized by electrochemical oxidation of a tin metal sheet in a nonaqueous electrolyte containing NH4F. The as-prepared nanoparticles were then thermally annealed at 700 C for 6 h. The resulting particles were characterized by a variety of experimental techniques, including X-ray diffraction (XRD), high-resolution transmission electron microscopy (HRTEM), Raman, ...

We fabricated nitrogen dioxide (NO2) gas sensors with p-type carbon nanotubes (CNTs) / n-type tin (SnO2) nanoparticle heterojunctions using one-step dielectrophoretic assembly and investigated the effect of CNT/SnO2 ratio on their NO2 detection properties. CNTs SnO2 nanoparticles were mixed in various ratios, suspended deionized water, assembled by dielectrophoresis. The normalized response het...

Nanocrystalline SnO2 core and ZnO as well as SiO2 shells coated core shell nanoparticles have been successfully synthesized by co-precipitation method. The as prepared samples were characterized by X-ray diffraction, FTIR, UV-Visible absorption, PL, FESEM, HRTEM with EDX measurements. The X-ray analysis showed that the obtained SnO2 core with tetragonal rutile crystalline structure and the shel...

Tin dioxide (SnO2), an n-type semiconductor with a wide band gap of 3.6 eV, has been widely used in photocatalytic degradation of organic dyes, photovoltaic devices, rechargeable lithium batteries, and so on. In particular, remarkable receptivity to variations in gaseous environments and excellent chemical stability have made SnO2 the bestknown gas-sensing material. Over the past decades, consi...

Proteins adsorbed on nanoparticles (NPs) are being used in biotechnology, biosensors and drug delivery. However, understanding the effect of NPs on the structure of proteins is still in a nascent state. In the present paper tin oxide (SnO2) NPs were synthesized by the reaction of SnCl4·5H2O in methanol via the sol-gel method and characterized by x-ray diffraction (XRD), Fourier transform infrar...

A sandwich-type immunosensor is designed and fabricated to detect the human immunoglobulin G (HIgG) using polyaniline and tin dioxide functionalized graphene (GS-SnO2-PAN) as the platform and biotin-functionalized amination magnetic nanoparticles composite (B-Fe3O4@APTES) as the label. GS-SnO2-PAN is used as the sensing agent to capture the primary anti-HIgG (Ab1) and SnO2 reduces the stack of ...

The influence of cobalt doping in SnO2 crystal lattice tailored the optical, structural, and surface properties SnO2.
