What is the full form of NMCE? - National Multi-Commodity Exchange - National Multi-Commodity Exchange (NMCE) was a multi-commodity exchange in India. It is backed by th
The full assignment of the ambient-temperature high-field 1H NMR spectrum for the reduced form of a repeat-unit 尾-linked tetrasaccharide derived by keratanase digestion from keratan sulphate, GlcNAc(6-SO4)13Gal(6-SO4)14GlcNAc(6-SO4)13Gal-ol, was achieved using two-dimensional COSY and ...
2.2.2. Nuclear magnetic resonance (NMR) Low-field NMR technology uses hydrogen or nucleus in water or water to resonate in a magnetic field and generate signal characteristics to detect oil, gas, water and their distribution, as well as physical properties of the medium. In the NMR process,...
Analysis of fecal metabolite concentrations by nuclear magnetic resonance (NMR) Fecal samples were homogenized in 1:12 w/v of saline phosphate buffer (1.9 mM Na2HPO4, 8.1 mM NaH2PO4, 150 mM NaCl) with 1 mM sodium 3-trimethysilyl-propionate-d4 (TSP-d4) mixed 1:1 v/v with deuterated wat...
of 167%, coinciding with that of completely mobile Na+ions of an aqueous sodium sulfate solution (Supplementary Fig.12). Thus, the Na element of SAG film totally exists in the form of mobile Na+ions with water uptake of 167%, and the content of dissociated Na+ions is up to 4.8 ×...
when the molar ratio a% of DBU is increased to 5.0%,P1-5.0DBUalso displayed obvious NIR CL at 740 nm, which is absent inP1-5.0TEA(Fig.3B), suggesting that DBU can form strong amine-ester complexes for NIR CL. Then, time-dependent NMR spectra of various mixtures of DBU and ester-...

For that reason, the anions possess some limited rotational and translational degrees of freedom that are activated at higher temperatures [22,23]. The methyl groups basically form a centrosymmetric environment with symmetry axes close to the ones of the octahedral anions. This implies that for non...
of chemical compounds, the combined strategy of NMR and LC–MS has also been applied [28,29]. Recently, new mass spectrometry imaging technology has been increasingly utilized to investigate diseases, particularly in the case of cancer [30,31]. It can visualize the location and quantity of ...
As the second-largest petrochemical after ethylene, propylene is widely used in many fields, especially in the form of polypropylene used in the medical field1,2. In industry, propylene is manufactured via steam cracking of light naphtha and fluid catalytic cracking of natural gas or coal with ...
