New Nanotubes Study Results from University of Utrecht Described
October 10th, 2011
Data detailed in "A quantitative electron tomography study of ruthenium particles on the interior and exterior surfaces of carbon nanotubes" have been presented. "The efficiency of filling carbon nanotubes (CNTs) by ultrasound-assisted wet impregnation is quantified by electron tomography (ET). For image analysis, a method that combines edge detection with single-value thresholding is proposed and validated," scientists writing in the journal Chemsuschem report.
"A high proportion (80 wt'%) of the ruthenium was deposited inside the tube at an average particle size of 2-4 nm. Particles located on the outer surface of the CNT had a size of 1-3 nm. The local ruthenium...
