His later years were taken up with the study of the contributions that life processes make to the atmosphere, and he correctly attributed to living things the creation of the oxygen, nitrogen, and carbon dioxide present in the atmosphere.
A Fourier transform infrared (FTIR) spectroscopy analysis of these particles indicated the presence of calcium carbonate produced by the reaction between the calcium hydroxide within the specimens and the carbon dioxide present in the solution.
The gas-diffusion module is based on a hydrophobic polyvinylidene fluoride (PVDF) membrane, which allows the transfer of the carbon dioxide present in the sample to a bromothymol blue (BTB) pH-sensitive acceptor solution, where the color change is measured optically.
Bubble formation in espresso brewing has been discussed by Navarini et al. 6 It has been hypothesized that during espresso coffee brewing, the solubilization of carbon dioxide (present in the coffee bed) in water at high pressure and temperature lead to a supersaturation conditions in the beverage.
Activation of the embryo within the shell and its subsequent release depend on other factors, including the amount of carbon dioxide present, in addition to the host's enzymes.
Potential effects of carbon dioxide present in the solutions are demonstrated for particular systems.
A new formula was used to determine the reduction in viscosity caused by carbon dioxide present in the fluid.
Yang, S. et al. Selectivity and direct visualization of carbon dioxide and sulfur dioxide in a decorated porous host.
Chemical Engineering Science 62, 4579 4588] about micro-oxygenation of wine, where, when dissolved carbon dioxide was present in the liquid phase, a surprising decrease in the value of the apparent kLa was pointed out.
The presence of such early carbonate sediments is evidence that carbon dioxide was present in the atmosphere, and it has been calculated that it was at least 100 times greater than the amount in the present-day atmosphere.
By working under conditions where carbon dioxide is present in large excess, and noting that the concentrations of catalysts 1 and tetrabutylammonium bromide will be effectively constant during the reaction, this can be simplified to Equation (2).
