Only one Si(4A1) signal is present in the NMR spectrum of X zeolite (Si/Al 1), but there are four signals (Si(3Al), Si(2Al), Si(1Al), and Si(OAl)) in Y zeolite. As Si(OAl) cannot create bridging hydroxyls, this implies three kinds of hydroxyls of various acid strengths ...
The molecular weight and thermal properties of polymers are summarized in Table 1. Figure 1 shows the 1H NMR spectra of monomer (3) and polymer (PCNVTPA) in CDCl3 and d-DMF, respectively. In the spectrum of monomer (3), the signals at 5.29, 5.75 and 6.69 p.p.m. are assigned to ...
The X-ray photoelectron spectroscopy (XPS) characterization assisted to determine the oxidation state of nanoparticles (Supplementary Fig.6). In theIr 4 fcore-level spectrum (Fig.1c), two groups of peaks located at 60.23/63.26 eV and 62.79/65.24 eV are attributed to the metallic Ir...

meet the other technical stability requirements (heat stability and/or light stability). IR absorbers, for example for security printing, are available, for example, from “American Dye Source”, but virtually all of them have an absorption in the VIS range of the spectrum (from 400 to 700 ...
Spectrum, and Crystal Structure Phenyldiazonium tetrachloronitridomolybdate, C 6 H 5 N 2 [MoNCl 4 ], was obtained in the form of orange-red crystals from phenyldiazonium chloride and molybdenum nitride chloride in POCl 3 suspension. In boiling di-n-butylether it decomposes to chlorobenzene ...
O-Ethyl (p-chlorobenzenesulfonamido)benzenethiophosphonate ( 1 ) is shown to be associated by hydrogen-bonding by means of its i.r. spectrum in CCl 4 solution. Quantitative examination allows to determine the dissociation konstant K , the temperature dependence of which leads to a 螖 H -...
The indenocarbazole and bipolar triazine-indenocarbazole moieties introduced into IrO1 and IrO2, respectively, afforded good solubility (>10mgmL 1 ) in chlorobenzene, making these emitters suitable for the fabrication of solution-processed devices. The obtained devices based on IrO1 with 4,4-bis(...
At the same time, PdO/H-Beta improves the selectivity of CO2, but also increases the production of chlorine. Giraudon et al. [32] studied the catalytic decomposition of chlorobenzene over Pd/ZrO2 and Pd/TiO2 materials. It was found that, because TiO2 has higher reducibility than ZrO2, the...
