According to the IPCC inventory guidelines, there were three main carbon accounting methods: the emission-factor approach, mass-balance approach, and experiment approach. The emission-factor approach was the first carbon emission estimation method proposed by the IPCC and was also the most widely appl...
Computer-aided molecular formula determination from mass, proton and carbon-13 NMR spectra 来自 ACS 喜欢 0 阅读量: 26 作者: B. G. Derendzhaev,S. A. Nekhoroshev,Konstantin S. Lebedev,S. P. Kirshanskii 摘要: ChemInform is a weekly Abstracting Service, delivering concise information at a ...
If the diffusion coefficient for oxygen is 1, the relative diffusion coefficients for different gases in the body fluid are as follows: carbon dioxide, 20.3; carbon monoxide, 0.81; nitrogen, 0.53; and helium, 0.95. Therefore, carbon dioxide diffuses more rapidly than oxygen across membranes. ...

Naturally occurring carbonate minerals were used in all solubility experiments. The origin of these carbonates, their calculated chemical formulae from electron probe microanalysis, measured unit cell parameters from X-ray powder diffraction, and Raman spectra are reported in ref.62. The fluids used we...
When the tumour volume reached ~150 mm3, the tumour mass was cut into smaller pieces with a volume of 2–5 mm3, which were then subcutaneously implanted into other mice. During the study, animals were observed every day for any clinically relevant abnormalities. If any mouse was moribund...
(1) assess the performance of PCs compared with annual crops (either as monoculture or crop rotation) in terms of relative SOC stock changes; (2) explore the time effect of perennialization on SOC stock difference compared with annual crops; and (3) study the effects of soil type, climate...
the N-, S-, and R-CNDs as prepared in three different syntheses will not have precisely the same mean mass per NP and also the mass distribution of the different samples will not be identical. For this reason, here concentration determination of the CNDs was performed based on their ...
Herein, a novel nitr[ogen-doped carbon dot (N-CD) fluorescence sensor with a dual emission ratio is developed using the microwave-assisted synthesis of m-phenylenediamine and spermidine. As a result of the fluorescence inner filtration effect (IFE) effec
