The elution positions of molecular mass standards derived from heparin (8.6 kDa) and hyaluronan (19, 30, 43 and 210 kDa) are indicated by arrows. TABLE 2. Glycosaminoglycan synthesis and disaccharide composition of labeled HS isolated after mock or siRNA mediated knockdown of EXTL2 in HEK 293 ...
The electron–water heptamer is one of the "magic" numbers in the mass spectra of electron–water clusters, but up to now the structure of the electron–wa... ML Han,SB Suh,KS Kim - 《Journal of Chemical Physics》 被引量: 71发表: 2003年 Enormously large (approaching 14 eV!) electron...
Meanwhile, the controllable hierarchical structure and surface atomic arrangements with abundant OVs will bring following benefits: (1) supplying sufficient surface active centers, (2) eliminating the blockages for mass transfer, (3) extending the utilization of visible light, (4) promoting the ...
Platinum determination in nutrient plants by inductively coupled plasma mass spectrometry with special respect to the hafnium oxide interference Platinum, emitted from automobile exhaust catalysts, is mainly oxidised in a humic soil, as described previously [1]. An experiment with nutrient plants wa......
Liquid chromatography-tandem mass spectrometry (LC-MS/MS) was used to analyze. The procedure of LC-MS/MS was based on previous studies with slight modification56,57. The data acquisition instrument system mainly includes Ultra Performance Liquid Chromatography (UPLC) (ExionLC™ AD) and Tandem ...
Accelerating the mass transport thus improves the overall reaction rate, which allows processing of more reactants. Thus, the volume of the required catalyst is reduced, allowing more compact reactors. Fabrication methods involve simple, low-cost and scaleable procedures, allowing the flow channel ...
Chemical graphitization from graphene oxide (G-O) to graphene has been introduced for mass production. The use of the vapour phase is needed to pattern hydrophilic G-Os on prepatterned substrates, as well as in in situ reduction to hydrophobic reduced graphene oxides (RG-Os). Moreover, a ...
Fresh mass of sunflower wasobtained by harvesting two rows of plants (row distance of 5 m) at 110 DAS and theresults were transformed into kg ha-1. Statistical analysis was the same as thatdescribed for Experiment 1. RESULTS AND DISCUSSIONExperiment 1. None of the herbicide treatments had ...
Mass blended ratio of H2 1. Introduction To mitigate the climate change caused by greenhouse emissions, the carbon-free fuels, ammonia (NH3) and hydrogen (H2), have been recognized as viable replacements for fossil fuels [1], [2], in line with the more stringent emission regulations [3],...
Indeed, in addition to the challenge to limit the heat exchange between LH2 and the outside of the tank, it will be necessary to tackle the possible instabilities that a sloshing mass with offsets with respect to the center of mass of the aircraft can generate. This work aims at ...
