FTIR measurements were performed on an FTIR spectroscope (PerkinElmer). rGO-sp3-rGO suspension (1 mg mL−1) was prepared in water through ultrasonication. A 10 μL portion of rGO-sp3-rGO ink was dropped onto the prepolished GCE. rGO-sp2-rGO- and rGO-coated GCEs were prepared...
FIGURE 2: Diffuse reflectance FTIR spectra of alkyl–amide packing (solid line) and starting silica (dashed line). on a 5-m dp, 80-Å, 180-m2/g Zorbax Rx-Sil silica support (Hewlett-Packard) by proprietary processes. The carbon values for this column packing typically were 10% for...
Such variation makes it possible to determine the influence of the size of the water pool on water H-bond structure and dynamics and the distribution of NMA-d7 solute in the RM. The approximate sizes of the water pools as well as the number of encapsulated NMA-d7 molecules are listed in...
A cooperative strengthening of hydrogen bond is manifested in the large increment of C O and N H bond lengths in DHBD, as compared to those in SHBD. 展开 关键词: δ-Valerolactam Matrix isolation FTIR Transient Amide-I Amide-A DOI: 10.1016/j.molstruc.2010.05.002 被引量: 9 ...

(FTIR) was tested by the IRTracer-100 spectrometer (Shimadzu, Japan) at room temperature. The Raman spectra were carried out by using a Raman spectrometer (Horiba, LabRAM HR800, USA). The morphology of Li deposited on Cu substrate after 10 cycles in Li||Cu cells was observed by FE-SEM...
Fig. 2 exhibits the FTIR spectra of pristine DWCNT and both FDWCNT. Few prominent peaks Conclusion The current work has summarized that the amino acid residues in L-tryptophan and L-DOPA act as a progressive source of functionalization probe incorporated within bi-layered graphene sheets in a ...
Ethanol acetamide was catalytically converted to a linear polyether as characterized by FTIR spectra. The catalysts were based on molecular strings of mono-, di- or tri-valent transition metal compounds that opened the amide carbonyl double bond to produce linear polyethers. Laboratory results have ...
Different from PUMHS, there is still one strong H-bond donor NH but two strong possible acceptors C=O and ether O in PUMSS (bottom of Fig.1). Fig. 2 shows their obvious differences in FTIR spectra in both νNH and νC=O bands. First, the peak of ...
