Characterization of graphene segregated on Ni

Yu Q., Lian J., Chen Y-P, Li H., Lian J., Pei S-S, University of Houston, US

We report a surface segregation approach to synthesize high quality graphenes on Ni under ambient pressure. Graphenes were segregated from Ni surfaces by carbon dissolving at high temperature and cooling down with various cooling rates. [...]

Synthesis of Self-aligned Tungsten Nanowires on Single Crystalline Tungsten Substrates

Wu W., Yu Q., Pei S-S, University of Houston, US

Metallic nanowires have attracted much attention due to their unique mechanical, magnetic, optical and electronic properties, and their function as well-defined building blocks for nanodevices.1-3 Tungsten (W), in particular, is of great interest, being promising [...]

Large scale synthesis of SiC nanofibers from various carbon precursors

Ritts A.C., Li H., Yu Q., University of Missouri-Columbia, US

In this proceeding submicron and micron sized graphitic particles were compared with MWNTs as precursors for producing several grams of SiC nanofibers in a 3’’ diameter hot-walled chemical vapor deposition reactor. Nickel nitrate and the [...]

Plasma Treatment of Nanofillers for Polymer Nanocomposites

Ritts A.C., Yu Q., Li H., University of Missouri-Columbia, US

Nanofillers were functionalized with amine groups using low-temperature plasma to enhance dispersion and interfacial tension with Epon 815C resin. The amine groups remained on the coating surface were anticipated to strengthen the interfacial interactions through [...]
