Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
A conductive and photocatalytic nanocomposite thin film comprising multiwalled carbon nanotubes (MWCNTs) and TiO nanoparticles is fabricated based on layer-by-layer (LbL) assembly in a nonpolar solvent, toluene. An amphiphilic surfactant, aerosol OT (AOT), is used to impart opposite surface charge onto MWCNTs and TiO in toluene. Our fabrication technique enables the incorporation of unoxidized MWCNTs into the nanocomposite thin films, and at the same time, provides a versatile method of fabricating conformal thin films over a large area. The physicochemical properties of MWCNT/TiO nanocomposite thin films, including composition and photocatalytic activity, can be varied by changing the concentration of AOT during assembly. The electrical properties of the nanocomposite film, specifically its sheet resistance and conductivity, can also be tuned through changing the assembly conditions. In addition, we demonstrate that the incorporation of MWCNTs within our films leads to a significant enhancement of the photocatalytic activity of TiO. The conductivity and enhanced photocatalytic activity of MWCNT/TiO thin films make them promising for the generation of highly efficient dye-sensitized solar cells (DSSCs). © 2010 American Chemical Society.
