The Raman spectrum observed for 13C-CNFs in Fig. 2B have both bands downshifted compared to the 12C spectrum in Fig. 2A. The frequency of Raman modes in samples containing a concentration, C, of 13C is deter- mined by the following equation which incorporates the increased mass of ...
In order to generate a reliable and long-lasting stable isotope ratio standard for CO 2 in samples of clean air, CO 2 is liberated from well-characterized carbonate material and mixed with CO 2 -free air. For this purpose a dedicated a cid r eaction and a ir mi xing s ystem (ARAMIS...
In the second step, the deposited trace metal elements was then irradiated by a CO2 laser beam to induce a plasma, obtaining emission spectrum of trace metal element. Using new present technique, trace metal analysis on a surface of material can successfully be carried out without damaging the ...
determined from the density-dependence of the Fermi diad splitting in the Raman spectrum and Ti-in-zircon thermometry. For both age periods, the CO2densities and Ti-in-zircon temperatures correspond to high-grade metamorphic conditions (≥5 to ≥7 kbar/~670 to 770 °C) that are typical of...
First, we used the intensity at the peak maximum and tracked the peak maximum as the spectrum changed with density. However, this approach was somewhat problematic because at mid and higher densities the lower energy spectral peak was at best not well-resolved, if at all identifiable. The ...
Before spectral fitting, each spectrum was corrected for reference binding energy for C1s to 284.8 eV. 3.2. Synthesis of N/S-Doped Porous Carbon Foam (NSPC) para-Nitroaniline (0.2–0.5 g) was placed in a ceramic crucible and wet with sulfuric acid while mixing with a stir glass rod, and...

The IR spectrum in the 600 to 4000 cm−1 range showed a specific interaction of the ionic liquid with the support. The N2 and CO2 permeances in the SILMs with [C4mim][BF4] were 8.7 × 10−8 mol·s−1·m−2·Pa−1 and 9.6 × 10−7 mol·s−1·m−2·Pa−1, ...
a tertiary ammonium vibra- tional peak at 1195.37 cm−1, and the peak at 6113898..8048 cm−1 1 is characteristic of the sulfonic acid group; the absorption peaks of the AM15P52S.10monomer functional groups appeared in the infrared spectrum of ZJL-1, which confirmed that ZJL-1 was che...
