Modern X-ray Scattering Methods for Nanoscale Materials Analysis
out of 5 stars
15 Oct 2008 | | Contributor(s):: Richard J. Matyi
Since its discovery by von Laue in 1912, X-ray diffraction has become an indispensable tool for structure determinations in the physical and biological sciences. X-rays are characterized by high energies and by wavelengths that are commensurate with nanometer-sized structures – unlike optical...
Nano*High: X-rays, Lasers, and Molecular Movies
25 Sep 2010 | | Contributor(s):: Roger W. Falcone
X-ray imaging is an excellent method to make visible what would normally be invisible - who hasn't had an X-ray at the doctor or dentist's office before? At the Lawrence Berkeley National Lab, the Advanced Light Source is a gigantic X-ray imaging machine. Dr. Roger Falcone discusses X-ray...
TiCN/TiNbCN Multilayer System with Enhanced Tribological Properties
20 Oct 2010 | | Contributor(s):: Pedro Antonio Prieto
Improvement in the mechanical properties of hard coatings such monolayer (TiN, CrN, AlCN, WC-Co, TiCN) , has been achieved using compositional gradient WC/C layer, or multilayered type [transition metal/transition carbide]n, [transition metal/transition nitride]n, [TiCN/ZrCN]n, among others....
X-ray Diffraction and Reflectivity Analysis of Thin Films and Nanomaterials
29 Dec 2009 | | Contributor(s):: Mauro Sardela
A review of x-ray analysis techniques applied to the characterization of nanomaterials will be presented with focus on x-ray lab source instrumentation similar to the facilities available at the Birck Nanotechnology Center. Practical aspects of data acquisition and interpretation using x-ray...
[Illinois] A Microfluidic Approach for Cocrystallization of Drugs and Analysis via X-ray Diffraction
16 Dec 2013 | | Contributor(s):: Elizabeth Horstman
The process of pharmaceutical drug development is cost- and time-intensive. Candidate drugs (CDs) are screened with many counter ions (salt or cocrystal formers) to find solid forms of the drug with appropriate physicochemical (e.g., solubility, dissolution rate) properties. Cocrystals are...
