Correlated X-ray Scattering of Metallic Nanoparticles at the Stanford Synchrotron Radiation Lightsource
Abstract/Contents
- Abstract
- This thesis reports on the results of a new method for interpreting x-ray scattering data as applied to silver and platinum nanoparticles. Correlated X-ray Scattering (CXS) is the subject of much interest due to the possibilities of imaging un-crystallized proteins. CXS can also give much more detailed information about the structure of nanoparticles than more traditional solution scattering x-ray techniques, and could thus be immensely helpful in industrial/technical studies. With their femtosecond pulses of high intensity x-rays, x-ray Free Electron Lasers (XFEL) are the obvious choice for CXS studies due to the large numbers of photons and short exposure times necessary for this technique. For applications, however, it is important to figure out when it is possible to use the much more common and cheaper, albeit less powerful, synchrotron x-ray sources. This experiment attempts to use the method of difference correlations on data from solutions of platinum and silver nanoparticles to see if meaningful and interesting data can be extracted using CXS with synchrotron radiation. It is shown that with proper filtering techniques it is possible to extract a CXS signal from nanoparticle data. From this signal the finer details of the internal structure of these nanoparticles were determined, including observation of twinning structures. Although it requires specific and careful sample preparation to a very high concentration, CXS is an extremely promising x-ray scattering technique with a wide variety of possible applications.
