Dispersion of Carbon Nanotubes with Organic Dyes

Zhang W., Wu C., Zhang W., Dalian University of Technology, CN

Owing to the presence of van der Waals’ forces, carbon nanotubes (CNTs) have the propensity to aggregate together and form bundles, which considerably hinders their applications. In this paper, organic dyes were used to suspend [...]

Water Splitting for H2 Production using Visible-light-responsive Photocatalysts

Huang J., Zhang G., Zhang W., Zhang G., Zhang W., Wang P., Minakata D., Chen Y., Crittenden J., New Jersey Institute of Technology, US

Hydrogen (H2) production using visible-light photocatalysis for water splitting has attracted considerable attention owing to the growing demand for environmentally friendly and sustainable energy sources. This presentation will demonstrate our previous study on H2 production [...]

Experimental Determination of Conduction and Valence Bands of Semiconductor Nanoparticles using Kelvin Probe Force Microscopy

Zhang W., Chen Y., Georgia Institute of Technology, US

Determination of the band gaps (Eg), positions of conduction and valence bands (Ev and Ec) is critical for the understanding of many photochemical processes (e.g., photocatalyst synthesis for decomposing organic compounds or splitting water for [...]

Recent Upgrades and Applications of UFDG

Fossum J.G., Trivedi V.P., Chowdhury M.M., Kim S-H, Zhang W., University of Florida, US

Recent upgrades of UFDG, a process/physics-based compact model for nonclassical MOSFETs having ultra-thin Si bodies (UTB), are overviewed, and several recent applications of the model are presented, exemplifying the potential benefits of FinFETs in nanoscale [...]

Determination of Frequency Dependent Fluid Damping of Micro and Nano Resonators for Different Cross-sections

Zhang W., Requa M., Turner K., University of California at Santa Barbara, US

This research is to quantitatively investigate the fluid damping of the MEMS and NEMS flexural resonators such as AFM and carbon nanotube resonators. We systematically explore the three most important factors which affect the fluid [...]
