Nanoparticles, particles with a diameter of 1-100 nanometers (nm), are of interest in many applications including device fabrication, quantum computing, and sensing because their decreased size may give rise to certain properties that are very different from those exhibited by bulk materials. ...
UV-Vis spectra show that the surface plasmon absorption feature of Au colloids is significantly reduced with increasing the amount of reduced Pt. TEM images that the metals are found always appear as spherical nanoparticles and their sizes grow apparently due to the reduction of PtCl2 6 ions, ...
Here we focus on the RS cross section of carbon nanoparticles of finite length, finding that the longitudinal polarizability of nanoparticles with different aspect ratios has resonances at frequencies that depend on the size and shape of the nanoparticle, originating characteristic signatures in the RS ...
isolated nanoparticlesA new technique for determining the magnetization direction of individual nanoparticles using the Foucault method of Lorentz microscopy is described. Experimental images for isolated SmCo 5 nanoparticles as a function of the objective aperture shift direction are shown. In preparation ...

The absorption peak of the silver nanoparticles colloidal solution was around 400 nm. The TEM images indicate that the silver nanoparticles had spherical shape and their sizes were from 10 to 17 nm. The particle size of the silver nanoparticles was confirmed by Zeta potential technique. The ...
a clear separation of the particle size as a function of elution time from about 80 nm to about 470 nm (Rg) was determined (black line under the LPX peaks). This indicates the validity of the AF4 method for analysis of the LPX nanoparticles in the present samples (see also for compleme...
The fluidization of TiO 2 -P25 nanoparticles is characterized by studying the X-ray attenuation through the bed and the dynamic response of pressure fluctuations to the influence of the gas velocity. The X-ray results are based on a flat detector capable of measuring a 2D projection of the ...
