Less than 1000 ppm CO2 in the background gas 311, 316, 317, 318, 3160 B-2C 3000T series L-2C More than 1000 ppm up to CO2 in the background gas All trace oxygen instruments A-2C Note: To use the A-2C or B-2C sensor in a 3000T series instrument, adapter part number B663...
Fixed data quality issues in CO2 emissions indicators (emissions less than 0, missing data for Eswatini, ...). Replaced all input CSVs with data retrieved directly from ourworldindata.org. 2021-02-08: Updated this dataset with the latest annual release from the Global Carbon Project. 2020-...
Primary oil recovery remains less than 10% in tight oil reservoirs, even after expensive multistage horizontal well hydraulic fracturing stimulation. Substantial experiments and simulation works have been performed to investigate CO2 enhanced oil recovery (CO2-EOR) potential in tight reservoirs; however, ...
The project adopts a two-phase absorbent with low energy consumption to capture CO2, and the regeneration energy consumption of such absorbent is less than 2.4 gigajoule per tonne, reaching the advanced level globally. The captured CO2 is then used to produce industrial products with wide applicatio...
The CO2 stores per body weight (CO2 stores/w) were linearly related to the CO2 pressure (P'vCO2) determined by the CO2 rebreathing method (r = 0.713, p less than 0.001), the slope being 0.330 ml/(mmHg X kg). The CO2 stores were then corrected for change in O2 stores with exercise...
hypothesis to explain a more efficient biological carbon (C) pump and the associated drawdown of atmospheric CO2. Yet, modelling focussed on the high latitudes has sequestered less than 10 ppm of atmospheric CO2via Fe fertilisation5,6,7and indicates that additional biological mechanisms are required...
However, it is acceptable if it is less than 10. Table A2 in the appendix reveals that centered VIF values of regressors, except GDP_pc, are less than 10. So, the regression suffers from multicollinearity slightly in terms of GDP_pc. The correlation matrix depicted in Table A3 yields also...
Surface vacancies allow for bent adsorbate configurations to be accessed but they are all less stable than the linear adsorbate. Bader analysis confirms that adsorption of bent CO2 is accompanied by charge transfer from the surface to the molecule, whereas minimal charge transfer occurs in linear ...
These only occur in the cases of low concentrations of CTAC (less than 10 wt%) or low concentrations of base (less than 5 wt%). When the CTAC concentration is above 10 wt%, excess CTAC can stabilize smaller toluene droplets within the water droplets, forming oil-in-water-in-oil...
In addition, the cost analysis indicates that slag-bond concrete blocks cost less than commercial cement blocks if produced in large quantities. Up to now, lots of carbon-capture construction materials have been obtained from steel slag carbonation, such as blocks [[40], [41], [42]], ...
