Collision induced dissociation (CID) of the peptides after the preferential bond cleavage results in formation of characteristic b and y ions, not the ETD-type c/z ions more typical of peptide radicals. For the peptides that incorporate the disulfide-containing moiety, prominent side-chain ...
Smooth hydrophobic coatings (WCAs 106°–108°) were obtained from both precursors, with enhanced deposition rates for TMDSO due to weak SiH bond. Levasseur et al. reported on deposition of hydrophobic coatings on wood surfaces in an enclosed parallel plate DBD driven at 12 kHz and 3.5 ...
The coordination number three of all atoms and bond distances at around 1.5 Å indicate that all the molecules were constructed with single bonds. A comparison of the average bond energy (BE=ΔHa/nB), single-bond-type delocalization energy (DE/nB), enthalpy of formation (ΔHf/(x/2)),...
However, the cleavage of a triple bond using non-transition-metal compounds is less explored. Here we report that an unsymmetrical diborane(4) compound could react with carbon monoxide and tert-butyl isonitrile at room temperature. In the latter case, the carbon–nitrogen triple bond was ...
C–C bond (C1). The peaks at 285.4 ± 0.2 eV and 286.4 ± 0.1 eV correspond to the trigonal phase with a sp2 C (C2) and the tetrahedral phase with a sp3 C (C3), respectively9,22,23. The other peak at 288.5 ± 0.5 eV is identified as ...
behavior of Li–S cells correlating the type of nitrogen functionality generated when the precursor is variated with the charge/discharge capacity developed during the cell operation. For this study, different carbon materials were prepared by the variation of the nitrogen source (melamine, ...
About 90% of natural N fixation on our planet is biotic and occurs thanks to soil microorganisms. Abiotic natural inducers are lightning and UV rays. Alternatively, N can be fixed with electrical equipment or industrially.Chemically, N fixation is splitting the triple bond in N2 and reducing it...
It is also quite diversified throughout the pyridine-type nitrogen atoms and seems to constitute a measure of relative basicity with respect to hydrogen-bond formation of the nitrogens concerned. This basicity seems to parallel that with respect to a full transfer of a proton, as can be ...
Significant effort has been made to directly reveal intermediate (I) since it precludes N–N bond formation and N–O cleavage, making it an essential subject for general NO reduction reactions. The electronic structure of (I) has been proposed to be Fe2+-NHO or Fe3+-NHO•-, amongst ...
