Imaging beyond the fundamental slope limit in surface metrology using fluorophore-aided scattering microscopy (2018)
Presentation / Conference
Liu, J., Liu, C., Li, L., Su, R., & Leach, R. (2018, November). Imaging beyond the fundamental slope limit in surface metrology using fluorophore-aided scattering microscopy. Paper presented at Special Interest Group Meeting: Structured & Freeform Surfaces

Topography measurement for smooth surfaces with high slopes, e.g. freeform optics, is a challenging task for optical measuring instruments as the light reflected by the tilted surface cannot be sufficiently collected by the objective, resulting in lo...

(Invited) Interaction of Anions with Partially Oxidized Carbon Nanotubes and the Influence on the Performance of Polypyrrole-Carbon Nanotube Composite Electrodes (2018)
Presentation / Conference
Wei, C., Akinwolemiwa, B., Yu, L., Hu, D., Xia, L., & Chen, G. Z. (2018, September). (Invited) Interaction of Anions with Partially Oxidized Carbon Nanotubes and the Influence on the Performance of Polypyrrole-Carbon Nanotube Composite Electrodes. Presented at AiMES 2018 Meeting, Cancun, Mexico

Partial oxidation of carbon nanotubes (CNTs) in mixed HNO3 and H2SO4 is commonly used for the preparation of polymer-CNT composites. This procedure, however, emits toxic NOx fumes, making it difficult for commercial scale-up. Herein we report an envi...
