The initial steps of rhodium cluster formation from zeolite-supported mononuclear Rh(C2H4)2 complexes in H2 at 373 K and 1 bar were investigated by infrared and extended X-ray absorption fine structure spectroscopies and scanning transmission electron microscopy (STEM). The data...

Tip-enhanced Raman nanographs: mapping topography and local electric fields.

Nano letters

El-Khoury PZ, Gong Y, Abellan P, Arey BW, Joly AG, Hu D, Evans JE, Browning ND, Hess WP.
PMID: 25741776
Nano Lett. 2015 Apr 08;15(4):2385-90. doi: 10.1021/acs.nanolett.5b00609. Epub 2015 Mar 09.

We report tip-enhanced Raman imaging experiments in which information on sample topography and local electric fields is simultaneously obtained using an all-optical detection scheme. We demonstrate how a Raman-active 4,4'-dimercaptostilbene (DMS)-coated gold tip of an atomic force microscope can...

Comparison of the Distribution of Morphological Disorganization of Pigmented Lesions in a Community-based Practice versus a University-based Clinical Setting as Measured by a Multispectral Digital Skin Lesion Analysis Device: Impact on Diagnosis.
