Manager, Advanced Materials Characterization Laboratory University of Delaware
"The nanoIR2 is a go-to tool for unique nanoscale IR analysis, and has solved many problems to the delight of our academic and industrial users."
"The University of Delaware purchased the nanoIR2 in a multiuser facility which I manage. Once the instrument was available to my users, it became a go to tool for unique IR analysis. The nanoIR2 has proved to be a very robust platform with great stand-alone AFM capabilities. The user interface is clear and very intuitive, and the software never crashes. Many problems in manufacturing and failure analysis have been solved or identified to the delight of my industrial users. I look forward to many more years of satisfying use of the Anasys nanoIR2".
13 mol% PHBHx
Tapping AFM-IR images show lenticular crystals; overall thickness (50 nm) indicates multilayer crystals. Characteristic IR absorption band of PHBHx. The band shape between 1700-1760 cm-1 reveals fairly similar crystallinity at different sites. An absorption band at 1510 cm-1 is also observed, indicating presence of aromatic moiety, not observed for 3.9 mol% sample. Data courtesy of Rabolt et. al, University of Delaware
