Trimethyl(phenyl)silane — a precursor for gas phase processes of SiCx:H film deposition: Synthesis and characterization

Encapsulation of β-Glucosidase within PVA Fibers by CCD-RSM-Guided Coelectrospinning: A Novel Approach for Specific Mogroside Sweetener Production

“…The vibrations caused by out-of-plane C–H deformations in the monosubstituted aromatic ring of phenylboronic acid were manifested by the presence of peaks within the range of 900–720 cm –1 . Furthermore, the stretching vibrations of B–O at 1260 cm –1 resulted from the diol complexation reaction between B–OH groups of phenylboronic acid and −OH groups of PVA, verifying the cross-linking of PVA and Db Exg1/PVA fibers using phenylboronic acid (Figure B and D). , …”

“…23,32 The vibrations caused by out-of-plane C−H deformations in the monosubstituted aromatic ring of phenylboronic acid were manifested by the presence of peaks within the range of 900− 720 cm −1 . 33 Furthermore, the stretching vibrations of B−O at 1260 cm −1 resulted from the diol complexation reaction between B−OH groups of phenylboronic acid and −OH groups of PVA, verifying the cross-linking of PVA and DbExg1/PVA fibers using phenylboronic acid (Figure 4B and D). 34,35 The presence of DbExg1 was proven by an absorbance peak appearing at 1650 cm −1 in both cross-linked and noncrosslinked DbExg1/PVA fibers (Figure 4C and D), which corresponded to the CO stretching vibrations around the amide I region.…”

Fabrication of SiC-Type Films Using Low-Energy Plasma-Enhanced Chemical Vapor Deposition (PECVD) and Subsequent Pyrolysis

“…Their continued presence in the spectra, as the polymer is being deposited, is indicative of the fact that the polymerization reaction occurs primarily through the vinyl bonds. The methyl (Si–CH 3 ) stretching bands at 1250 cm –1 (region iv), which are prominent in the VPDMS spectra, also remain in the pVPDMS polymer and in the p­(VPDMS-co-DVB) copolymer spectra, indicating that these bonds have remained relatively intact during polymerization . The aromatic (C 6 H 5 ) C–C and CC (region v) stretching bands between 1300 and 1600 cm –1 that are prominent in both the VPDMS and DVB spectra are still present in the pVPDMS and in the p­(VPDMS-co-DVB) copolymer spectra, again indicating that these bonds remained relatively intact during polymerization .…”

Binary Solution Behavior for the Trimethoxyphenylsilane and Trimethylphenylsilane Under CO2 as Supercritical Fluid

“…2 Ermakova et al have discussed the possible use of TMPS as a precursor in the processes of CVD. 2 Exploring the phase behavior of TMOPS and TMPS under supercritical CO 2 (S-CO 2 ) can offer valuable insights and potential applications in various fields. The relevance of the present study can be summarized as follows: (1) Advancement of supercritical fluid technology: This research contributes to our understanding of the phase behavior of binary mixtures involving supercritical CO 2 and organosilicon compounds.…”
