X-Ray Facility

The departmental x-ray diffraction facility at CCB is dedicated to the collection and analysis of high-quality x-ray diffraction data of materials of interest to the faculty and their collaborators. The physical forms of these materials include single- or poly- crystalline (powder) solids, liquid crystals, polymers (and bio-polymers), and deposits on substrates, mixtures and composites having good or poor crystallinity.

Analyses include molecular and crystal structure determination (single-crystal or powder),finding lattice parameters, phase identification, percent crystallinity, crystal perfection (rocking curves), residual stress or texture analysis, orientation of crystallite planes and bulk crystal orientation for very large (1 – 30 mm) or very thin (<50 nm) single crystals.

The users of the x-ray facility (including trained students and technicians) are in complete compliance with radiation safety (NJ and Rutgers) and all applicable NJ state laws, and are trained on-site by the lab manager.
