The bioprocessing of CeO2 nanoparticles after uptake in lung tissues is compared with the formation of nanoparticles after inhalation of CeCl3 aerosols. In both cases, high-resolution TEM/STEM analyses indicate that cerium phosphate nanoparticles (NPs) had precipitated in phagolysosomal regions within macrophages. Importantly, the primary particle size, morphology, and agglomeration tendencies ...

Plate-like BaTiO3 particles with a size of about 200 nm in thickness and 3 μm in width were prepared by using a novel solvothermal soft chemical process in ethanol and water-ethanol mixed solvents. A layered titanate of H1.07Ti1.73O4 with a lepidocrocite-like structure and plate-like nanoparticle morphology was used as the precursor, and solvothermally treated in the Ba(OH)2 solution to prepare...

Abstract The detailed characterization of snow particles is critical for understanding the settling behavior and modeling ground accumulation various applications such as prevention avalanches snowmelt‐caused floods, etc. In this study, we present a particle analyzer simultaneous measurements properties fresh falling snow, including their size, shape, type, density. consists digital inline holo...

In this experimental study, aerosol methods for producing titanium dioxide powders and increasing our knowledge of particle and crystal formation have been developed. Powders and ultrafine particles of titanium oxide were produced by an aerosol droplet decomposition route in tubular laminar flow reactors in air and nitrogen atmospheres. Reactor temperatures up to 1500°C were used with residence...

   We report an investigation on the synthesis of Copper Oxide nanostructures via the Electro-Explosion of Wire method. Cu-CuO and Cu-Cu2O nanoparticles with mean particle size of 21.1 to 59.1 nm were synthesized by changing the applied current density and amount of used Tetra Methyl Ammonium Hydroxide as the surfactant. The X-ray diffraction analysis, field emission scanning ele...

Production of Fe-C alloy powders by mechanical alloying was studied. Fe and graphite elemental powder mixtures containing 0.8 and 1.5wt.% graphite were mechanically alloyed using a planetary ball mill. The structural changes of powder particles during mechanical alloying were studied by x-ray diffractometery, scanning electron microscopy and microhardness measurements. For both compositions, me...

Nanostructured iron oxide powder that has been recovered from waste pickling liquor unit of steel industry was studied for oxidation catalytic applications. In this research, the powder was characterized by X-ray diffraction (XRD) and transition electron microscopy (TEM) for determination of phase structure, morphology and particle size. Furthermore, the specific surface area of the powder was ...

We report on the measurement of morphology-dependent resonance within a laser-trapped micro-sphere excited under two-photon absorption. Both trapping and two-photon excitation are simultaneously achieved by a single femtosecond pulsed laser beam. The effect of the laser power as well as the pulse width on the transverse trapping force is first investigated. The dependence of two-photon-induced ...
