A study of carbon Kα peak shifts using an electron probe micronalyzer (EPMA) with a vanadium-carbon multilayer pseudo-crystal (2 d = 96 ) shows a distinct peak shift between diamond and graphite and two organic carbon phases (asphaltene and vitrinite). The peak shift reflecting the differenc...
The XRD peak broadening is in direct relation with the structural anisotropy and heterogeneity in the rolling plane during deformation by deep drawing in mild soft steel. The inhomogeneous structures give internal stresses at different scales, which strongly influence the superficial mechanical properties....
Ru et al. synthe- sized superstructures from chiral carbon dots and L-/D- glutamic acid which showed a peak in CPL spectra at the same wavelength as the PL peak, namely, at 450, 560, and 610 nm59 (Fig. 6c). Zheng et al.64 fabricated thin films from the mixtures of blue/yellow/...
For the large crystallite size with few defects the G-peak is more intense than D-peak while by increasing the defects the ID/IG ratio increases. This increasing trend stops when the amount of defects exceed a certain value and the D-peak intensity starts to decrease [106]. Download: ...
XPS results show that the C 1s peak at 283 eV corresponding to acetylene black, decreases during discharge and increases during charge. These results suggest that porosity of the electrode decreases during discharge and increases during charge. 展开 关键词: conductive additive porosity carbon black X...
The XRD patterns were collected on a Bruker D8 ADVANCE with Cu Kα radiation (λ = 1.5406 Å) at 40 kV and 40 mA. The XPS analysis was measured on a Thermo EXCALAB 250Xi apparatus with a monochromatic Al Kα X-ray source. All data was calibrated by the C 1s peak at...
while in alkaline the activity difference is less noticeable between the Pd-based electrocatalyst materials. One of the mesoporous N-doped carbon supported Pd catalyst was also compared to Pd/Vulcan cathode in single-cell alkaline anion exchange membrane fuel cell and improved peak power density was...
It was observed that impregnation of bimetals enhanced the catalyst characteristics where include important results from FTIR, TGA, XRD and H2-TPR. Based on the results presented in H2-TPR analysis, it was observed that the reduction peak of bimetal catalysts deposited on palm kernel shell ...
s most important physicochemical properties driving dissolution, including the relative dielectric permittivity (dielectric constant,εr)45and the level of self-ionization46. From ambient to our peak experimentalP–Tconditions, theεrof water is lowered by a factor of two44, while the ion product ...
3b, an obvious larger ethane pulse peak was observed for Ru/SiO2 with the peak area ratio of ethene to ethane (R) reached 5.5. However, the formation of ethane was almost totally inhibited for Na-Ru/SiO2 case with R value surged to 22.5, in accordance with the observed phenomenon for ...
