Reflectance infrared spectra of all the minerals from CE5 lunar samples exhibit broad absorption in the range 3200–3800 cm−1and centered around 3500 cm−1, which indicates the existence of OH groups (Fig.1a–c, Supplementary Data1). In particular, a small peak centered around 3300...
The largest difference is that the water-perturbed oil spectrum appears narrower, and the peak ratio of 2105 cm−1 over 2196 cm−1 is increased compared to bare oil, both suggesting the interfacial oil may be more ordered. Indeed, similar behavior is commonly observed in lipids at ...
The FTIR spectrum is a crucial instrument for demonstrating how macromolecules’ functional groups are impacted. After 15 days of adsorption, the new peak at 3276.13 cm−1 which symbolizes the elongation of the hydroxyl groups shifted to 3264.89 cm−1 (Fig. 9), demonstrating that the combinati...
200 μm particle size, C0= 30 mg/L, and 200 rpm). As can be shown, the chromium elimination by CRS raised beside rising contact times, reaching a peak at 80 min. The fast rise in chromium elimination with the rise in the processing time is a result of the great number ...
The UV–visible spectrum of the polymer samples indicates that polarons act as charge carriers in all the polymer samples. From the FT-IR spectral studies, the characteristic peak position of PANI/TIT composite ion-exchanger was modified after the incorporation of individual inorganic ion-exchanger....
When the reaction of D5 was carried out at 300 °C for 6 h under argon, the IR spectrum (Fig. 4b) of the solid obtained by drying the aqueous phase after hexane extraction was similar to the spectrum of DMSD (Ortega et al., 2012). Based on the IR spectrum of DMSD, the ...
From the BFTEM images, it can be observed that a part of IL from the Florisil surface is degraded (the black spots are in a smaller amount), but there is still a very good coating with the Pd ions. This conclusion can be raised from the EDX spectrum where the peaks specific for the...
This band obviously decreased and exhibited a slight blue shift after addition of 7.0 µM Ag+; a new peak at 570 nm was also observed (ε = 5.8 × 104 M−1 cm−1). These results can be explained by an effective energy transfer mechanism. The absorption spectrum of the probe at ...

We further coated a stretching peak around 1050 cm−1, which can be clearly thin layer of GO on the surface of the ultrasonically treated fish identified from the FT-IR spectrum of pristine GO, indicating scales. To our surprise, the CA increased to 155° (Figure 2e), the presence...
