Double bond conversion can be experimentally determined by infrared spectroscopy (IR), Fourier-transform infrared spectroscopy (FTIR), or mid-infrared spectroscopy [8,9]. Upon IR irradiation the atoms of a molecule are energized and vibrate in patterns like stretching, bending, and rotation. Differen...
The results demonstrate that the a-BC thin film alloy exhibits amorphous carbon characteristics, and the Fourier Transform Infrared Spectroscopy (FTIR) results show that a little hydrogen was incorporated into the a-BC thin film alloy. X-ray photoelectron spectroscopy (XPS) indicated that the B/C...
Detecting the presence of active insects in various stages of their lifecycle within an art object is often difficult in the absence of direct visualization of the insect. It usually relies on one's ability to assess the evidence of their activity around, on, or in the object. To augment th...
As shown in Fig.3a, FTIR spectra of OPD feature two kinds of amino (−NH2) vibration bands located around 3367 and 3200 cm−1, respectively25,26. Due to the effect of hydrogen bond, −NH2vibration around 3200 cm−1is broadened about 100 nm. The stretching vibration of methy...
(corresponds to a reversible hydrogenation of a –N=B-bond) in the catalytic cycle. However, the stability of BCN under strong ultraviolet irradiation is remarkably increased by adding Pt (Supplementary Fig. 12b). We can speculate that the Pt is avoiding the over-reduction of the –N=B-...
and their magnetic surfaces are stirred at 25 °C, followed by refluxing in EtOH for 12 h at 80 °C to produce γ-Fe2O3-MgO@Ch. F. and γ-Fe2O3-MgO@Ch.CN, respectively. Finally, the catalysts synthesized are characterized through TGA, FTIR, FE-SEM, VSM, EDS, BET, and XRD me...
(SR-FTIR) spectroscopy validated that adsorbed oxygen atom on Ru site to form O-Ru1-N4site under the operating condition. The oxygen adsorption could downshift the Ru 4d band and increase the average valence state of Ru, which is responsible for reducing the limiting reaction barrier. Wu and...
FTIR化学键碳分子氮杂质铅离子放射性Since Liu and Cohen predicted that the bulk modulus of carbon nitride films with the structure of 尾-C3N4 are comparable or even surpass those of diamond, intensive experimental efforts have been done to synthesize this new material. Various kinds of synthesized ...
After treated in a flow of H 2 at 500 °C for 60 min, CNTs showed moderate sign of hydrogenation. Intense hydrogenation of CNTs occurred under similar treatment when 1 wt.% of Pd was supported on CNTs. In situ FTIR investigation of NO (5000 ppm) interaction with hydrogenated CNTs showed...
