Our Mission		NEW Book on Powder Diffraction Single Crystal Diffractometers for Chemical Crystallography Powder Diffractometers for Materials Characterization
is to provide the services and resources as well as the education and training to students and researchers in the theory and practice of X-ray Diffraction, Chemical Crystallography and Materials Characterization.
XCC offers:
State-of-the-Art X-ray Diffraction Facilities
Quality Service & Competitive Rates
Experience & Expertise
and performs:
Characterization of materials using non-destructive X-ray diffraction analysis and crystal structure determination from single crystal and polycrystalline samples:
Chemical Crystallography provides single crystal structure determination of variety of inorganic, metal-organic, organic and pharmaceutical compounds as well as minerals and intermetallic compounds, including absolute structure determination and treatment of merohedral and non-merohedral twins, disordered, OD and modulated crystals at low, ambient or elevated temperature, in open or inert atmosphere.
Materials Characterization: provides powder X-ray diffraction analysis and characterization of of polycrystalline and nano-crystalline materials and thin films, covering phase identification, qualitative and quantitative analysis, degree of crystallinity / amorphous content determination, micro-diffraction and area mapping, samples of any size and shape, texture measurements, crystallite size and micro-strain determination, ab initio indexing and high precision unit cell refinement, crystal structure refinement using the Rietveld method or pair distribution function, as well as ab initio structure determination from powder diffraction data.
Macromolecular crystallography: coming soon
The Center also:
offers its equipment and expertise for Collaborative research with other local universities, government institution as well as industrial research laboratories located in Maryland, Virginia, Delaware, Washington DC, and nationwide.
and provides Consulting in the field of X-ray diffraction, crystallography & solid state and materials chemistry.
