Areas of Interest
The Ade research group is developing and using novel characterization tools to determine the composition, morphology and structure of polymeric and electronic
materials at the sub-micron spatial scale. Of particular interest is the quantitative mapping of the chemical composition and the orientation of specific chemical
groups in multi-component polymeric devices, and the structure-property relationships in these materials. Characterization is achieved by Near Edge X-ray Absorption
Fine Structure (NEXAFS) microscopy and through the use of Resonant Soft X-ray Reflectivity and Scattering (RSoXR/RSoXS). The latter methods are still under active
development and hold great promise as characterization tools for organic materials. The research is highly interdisciplinary and benefits from extensive
collaborations with other research groups and industry. H. Ade has lead a team that developed a Scanning Transmission X-ray Microscope at
the Advanced Light Source in Berkeley dedicated to the research of synthetic and natural polymers. This "Polymer STXM" team is comprised of researchers from
NCSU, McMaster, Dow Chemical, ALS, SUNY@Stony Brook, NIST, and the Geophysical Laboratory. (click here for
more info on Polymer STXM). The microscope developed is now commercially available in adapted form from Accel.
