Observation of Magnetic Edge State and Dangling Bond State on Nanographene in Activated Carbon Fibers

, 2011
The electronic structure of nanographene in pristine and fluorinated activated carbon fibers (ACFs) have been investigated with near-edge x-ray absorption fine structure (NEXAFS) and compared with magnetic properties we reported on previously.

Influence of bond defects on coiling of graphite

Science and Technology of Advanced Materials, 2006
The effect of annealing at 1400 °C in argon on the bond structure of graphite ball milled for 100 h at 400 rpm in polar (water) and in non-polar (n-dodecane) liquids was investigated primarily by near-edge X-ray absorption fine structure spectroscopy ...

NEXAFS and XPS Studies of Co Doped Bismuth Magnesium Tantalate Pyrochlores

Chemistry
Co doped bismuth magnesium tantalate with a pyrochlore structure (sp. gr. Fd-3m) was synthesized for the first time using the standard ceramic method. Single phase Bi2Mg1−xCoxTa2O9 samples were found to be formed when x < 0.7 in the X-ray phase analysis.

Nanoscale NEXAFS for Probing TiO2 B Nanoribbons

, 2018
TiO2 nanostructures exist in different crystallographic phases including brookite, anatase, rutile, and TiO2 amp; 8722;B bronze . Among these, due to its open channel like crystal structure which can enhance ion mobility, the TiO2 amp; 8722;B phase has been reported as an optimal anode material for lithium ion batteries, particularly in the form of ...
