Forest Productivity Estimated from Carbon Dioxide Uptake
Ecology, 1970Net photosynthesis of the three dominant tree species of the oak—pine forest of central Long Island was monitored intensively throughout one growing season to test the practicality of field measurements of net photosynthesis for estimating gross production of a forest.

Estimation of how much of the rising atmospheric burden of carbon dioxide is taken up by the oceans is central to predicting how climate may change. Making such measurements is a highly demanding task, not least because the annual increase in oceanic CO2is tiny.

Carbon dioxide uptake by succulents
Canadian Journal of Botany, 1971Carbon dioxide absorption by a selection of succulent plants, was followed by a modification of Tregunna's method, in which the plant sample on absorbing the carbon dioxide from an enclosed volume of air in contact with weak bicarbonate, causes the solution's pH to change.

Uptake of Atmospheric Carbon Dioxide into Silk Fiber by Silkworms
Biomacromolecules, 2003The relation between the uptake of atmospheric CO(2) and insect's production of silk fiber has not yet been reported. Here, we provide the first quantitative demonstrations that four species of silkworms (Bombyx mori, Samia cynthia ricini, Antheraea pernyi, and Antheraea yamamai) and a silk-producing spider (Nephila clavata) incorporate atmospheric CO ...

The uptake of carbon dioxide by plant roots
Plant and Soil, 1962The uptake of C14O2 by the roots of intact tomato plants from solution containing Na2C14O3 was studied at different light intensities as well as in darkness.

Some effects of carbon dioxide on foreign gas uptake
Journal of Applied Physiology, 1959Partitional respirometry in normal subjects breathing 1-5% CO2 indicates a large increase of alveolar dead space, but in the steady state there is no consistent change of diffusing capacity or effective pulmonary blood flow. An apparent early decrease of diffusing capacity is probably an artefact due to difficulties in measuring acetylene uptake with ...

Highly Selective and Stable Carbon Dioxide Uptake in Polyindole-Derived Microporous Carbon Materials
Environmental Science & Technology, 2013Adsorption with solid sorbents is considered to be one of the most promising methods for the capture of carbon dioxide (CO₂) from power plant flue gases. In this study, microporous carbon materials used for CO₂ capture were synthesized by the chemical activation of polyindole nanofibers (PIF) at temperatures from 500 to 800 °C using KOH, which resulted

Enhanced carbon dioxide uptake by the world's oceans
Energy Conversion and Management, 1996Abstract The growth of phytoplankton over much of the ocean is limited by the availability of nitrogen in the upper sunlit region of the ocean. It is through photosynthesis that upper ocean carbon is exported to the deep ocean and replaced with carbon dioxide fluxed by physical processes from the atmosphere.

Boar spermatozoa were diluted in Ringer’s fructose or sulfate buffer and incubated aerobically for 4 hr at 37 C (a) in the presence of potassium hydroxide (KOH), hyamine hydroxide, or diethanolamine (DEA) absorbents, and (b) in 1, 2, or 3% atmospheric levels of carbon dioxide.

Minerals for enhanced carbon dioxide uptake by the ocean
2022The amount of carbon dioxide that the ocean can absorb without becoming highly acidic depends on the alkalinity of its surface water. This term refers to the amount of acid-binding mineral components that were previously dissolved from weathered rock and washed into the ocean.
