“…The FTIR and NMR spectra of the synthesized benzimidazolones showed the compounds to have several functional groups: A band due to Si–O–C at 1085.41 cm(−1), a broad band at 3380 cm(−1) and chemical shifts: positive distortionless enhancement by polarization transfer (DEPT) (13)C peaks (indicating lack of CH(2) and CH(3) groups), (1)H NMR – 11.053 ppm (N–H), 7.086 ppm (Ar-H); (13)C NMR – 155.34 ppm (C[double bond, length as m-dash]O), 101.04 ppm (C–Br) characteristic of benzimidazolones. …”

“…Here we show that fluid-derived veins are preserved within the Zermatt-Saas ultra-high pressure serpentinites providing key evidence for carbonate mobility during serpentinite devolatilisation. We show through the O, C, and Sr isotope analyses of vein minerals and the host serpentinites that about 90% of the meta-serpentinite inorganic carbon is remobilized during slab devolatilisation. …”

“…Here we introduce a class of massive interstitial solid solution (MISS) alloys by using a highly distorted substitutional host lattice, which enables solution of massive amounts of interstitials as an additional principal element class, without forming ceramic phases. For a TiNbZr-O-C-N MISS model system, the content of interstitial O reaches 12 at.%, with no oxides formed. …”

“…The chemical composition analysis of tar by GC × GC-MS demonstrated that compared with under N(2), the contents of phenols, oxygenated compounds, and heterocyclic compounds in tar under SCGG were decreased while the content of aromatics was the opposite mainly due to hydrogenation and reforming reactions of nascent tar. Also, the H/C and O/C ratios of char under the action of SCGG were higher than those under N(2) at the same temperature.…”
