چکیده

A combinatorial high-throughput approach is used to investigate a solution cast gradient consisting of colloidal gold nanoparticles on top of a silicon substrate by means of a X-ray nanobeam. Classification algorithms are used to reveal and visualize structural transitions from a frozen colloidal solution to a well-defined nanostructure. Prominent length scales on the order of 100 nm are observed. A periodic change in the nanostructure along the gradient is explained by a simplified stick-slip model.

Investigation of structural effects of Bi nanoparticle addition on HTSC- BSCCO-2223,Through The sol-gel Method

In this research, the influence of Bi nanoparticles addition on the high temperature superconductor BSCCO-2223 was studied. For this purpose, the samples were synthesized by the conventional sol-gel method. Then, the Bi nanoparticles with x= 0.00, 0.03, 0.06, 0.12wt% was added to BSCCO-2223. The structural characterization of all the samples was done by X-ray diffraction pattern (XRD). Also, th...

Nucleation and growth of gold nanoparticles studied via in situ small angle X-ray scattering at millisecond time resolution.

Gold nanoparticles (AuNP) were prepared by the homogeneous mixing of continuous flows of an aqueous tetrachloroauric acid solution and a sodium borohydride solution applying a microstructured static mixer. The online characterization and screening of this fast process ( approximately 2 s) was enabled by coupling a micromixer operating in continuous-flow mode with a conventional in-house small a...

Investigation of Physical Properties of e-Beam Evaporated CdTe Thin Films for Photovoltaic Application

CdTe thin films with 2.8 µm thickness were deposited by electron beam evaporation method. X-ray diffraction, scanning electron microscopy, UV-Vis-NIR spectroscopy and atomic force microscopy (AFM) were used to characterize the films. The results of AFM analysis revealed that the CdTe films have uniform surface. CdTe thin films were heat-treated by SnCl2 solution. Structural analysis using XRD s...
