Biological systems for uptake of carbon dioxide
Energy Conversion and Management, 1992Photosynthetic processes provide environmentally sustainable mechanisms for removal of CO2. Biological systems produce biomass which can act as a reservoir of carbon or as a direct substitute for fossil fuels. Three alternative strategies are examined and compared: Sequestration of carbon by reforestation; growing energy crops to offset the use of ...

Carbon Dioxide Uptake by Concrete Modified With Carbon Nanotube
Volume 6: Polar and Arctic Sciences and Technology; Offshore Geotechnics; Petroleum Technology Symposium, 2013CO2 emission from fossil fuel fired power plants contributed 30% of global emissions in 1990. In the same year, the cement industry contributed about 5% of the total. According to Kyoto Protocol, a tremendous effort is required to reduce the carbon dioxide emission. One potential technology in CO2 mitigation responses is the use of concrete products as

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 ...

Nature, 1998
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.

Influence of Carbon Dioxide on the Uptake of Water by Asparagus
Nature, 1965EXCISED shoots of asparagus (Asparagus officinalis L.) with cut ends immersed in tap water undergo a marked gain in fresh weight during storage in atmospheres containing more than normal amounts of carbon dioxide1. Shoots, 16 cm in length, were stored in chambers at 1.7° C in darkness for one week.

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.

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 ...

The Role of the Southern Ocean in Uptake and Storage of Anthropogenic Carbon Dioxide
Science, 2000An ocean-climate model that shows high fluxes of anthropogenic carbon dioxide into the Southern Ocean, but very low storage of anthropogenic carbon there, agrees with observation-based estimates of ocean storage of anthropogenic carbon dioxide. This low simulated storage indicates a subordinate role for deep convection in the present-day Southern Ocean.

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.
