C Beermann,AK Röhrig,G Boehm 摘要: The goal of this work was to alter the composition of amide-linked FA of bovine buttermilk gangliosides, particularly the disialoganglioside GD 3 , to adjust lipid sources to special food specifications and pharamacological or cosmetic applications. The ...
The distinct aroma composition of these ancient champagne samples, first revealed during tasting sessions, was later confirmed using state-of-the-art aroma analysis techniques. After 170 y of deep sea aging in close-to-perfect conditions, these sleeping champagne bottles awoke to tell us a chapter...
The solid composition is determined by the partial densities of the respective solid species, described in 2.2 in more detail. As a first step, it is assumed that the particles are completely entrained with the gas flow, resulting in the same residence time as the gas phase. Fig. 2 shows ...
In the present study, an approach for the detailed componential characterisation of torrefaction tar has been shown for the first time. The aim of this study was to evaluate the chemical composition of torrefaction tar using FT-ICR MS, two-dimensional 1H-13C HS-QC NMR, headspace gas chromatogr...
If a wealth of analytical data has already been published about the composition of grape and wine,1,2,3,4,5 recent non targeted analyses have emphasized the extent of the yet unknown bio-chemistry involved throughout the winemaking process.6,7,8 Such quest for the description and the underst...
Most compounds were shared among species, but their relative composition was significantly different. By comparing chemical distances of mandibular gland secretions to species divergence times, we showed that the secretions' compositions are not strictly determined by phylogeny. By identifying chemical ...
EA-CR series silicate composition rapid analyzer is designed for the silicate industry that has long used gravimetric method, volumetric method, spectrophotometric method, flame photometric method and atomic absorption photometric method to combine chemical analysis of materials. The ...
modelled paths terminate when the melt has fully crystallized (see the “Methods” section for details). While all degassing paths start at a melt fraction of 1 at varying SiO2concentrations, the evolution of the melt fraction and melt composition was parametrized from a compilation of experimental...
Until now, processes that use chemical composition criteria have been limited to those which use electrodes (which are relatively inaccurate and require frequent replacement) or to those which use mass spectrometry or combination gas chromatography and mass spectrometry. These later cases are slower in...
