Students will learn how scientists use a process called X-ray diffraction to figure out the structure of things that are too small to see such as atoms, molecules, and crystal structures.This lab will help students understand how light is bent into different directions as it interacts with small...
Why is sqrt(16) used in calculation of frequency given the wavelength of the light used?
Closed | Responses: 0
In Slide number 54 of this slideset, the calculation of frequency uses sqrt(16), given the wavelength of the light used for the diffraction.
What is the reason behind the same?

[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...
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....
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...
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...

Modern X-ray Scattering Methods for Nanoscale Materials Analysis
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...
