Global uptake of carbonyl sulfide (COS) by terrestrial vegetation:Estimates corrected by deposition velocities normalized to the uptake of carbon dioxide (CO2)
Global uptake carbonyl sulfide terrestrial vegetation deposition velocities
2010/1/12
COS uptake by trees, as observed under dark/light changes and under application of the plant hormone abscisic acid, exhibited a strong correlation with the CO2 assimilation rate and the stomatal condu...
Net ecosystem exchange of carbon dioxide and water of far eastern Siberian Larch (Larix cajanderii) on permafrost
Net ecosystem exchange carbon dioxide far eastern Siberian Larch permafrost
2010/1/7
Observations of the net ecosystem exchange of water and CO2 were made during two seasons in 2000 and 2001 above a Larch forest in Far East Siberia (Yakutsk). The measurements were obtained by eddy cor...
Biogenic controls on the air–water carbon dioxide exchange in the Sundarban mangrove environment, northeast coast of Bay of Bengal, India
Biogenic controls undarban mangrove environment
2014/5/14
The Sundarban mangrove forest (4,264 km2
) constitutes about 3% of the total area of the world mangrove. We
measured diurnal and seasonal variations of air–water CO2
exchange in relation to the occ...
Carbon Dioxide Transport and Carbonic Anhydrase in Blood and Muscle
Zentrum Physiologie, Medizinische Hochschule
2014/3/31
One of the major requirements of the body is to eliminate CO2. The large, but highly variable, amount of CO2 that is produced within muscle cells has to leave the body finally via ventilation of the a...
Natural variability of carbon dioxide and net epilimnetic production in the surface waters of boreal lakes of different sizes
carbon dioxide net epilimnetic production
2014/6/9
The variability of surface water carbon dioxide concentration, or partial pressure (pCO2
), was studied in 11 lakes
of greatly varying size (2.4 ha up to 8 million ha) in Northwest Ontario, Canada. ...
Carbon dioxide and methane evasion from a temperate peatland stream
Carbon dioxide methane evasion a temperate peatland stream
2014/6/9
Peatland streams potentially represent important conduits for the exchange of gaseous carbon between the terrestrial ecosystem and the atmosphere. We investigated how gaseous evasion of carbon from th...
Carbon dioxide partial pressure and 13C content of north temperate and boreal lakes at spring ice melt
Carbon dioxide partial pressure 13C content north temperate boreal lakes spring ice melt
2014/6/9
Carbon dioxide (CO2) accumulates under lake ice in winter and degasses to the atmosphere after ice melt. This large springtime CO2 pulse is not typically considered in surface-atmosphere flux estimate...
Microporosity in Montmorillonite from Nitrogen and Carbon Dioxide Sorption
Microporosity Montmorillonite Carbon Dioxide Sorption
2012/2/13
Nitrogen adsorption at 78亱K and carbon dioxide sorption at 195亱K on homoionic lithium, sodium, caesium, calcium, lanthanum and hexane diammonium saturated montmorillonites have been examined by means ...

Interlamellar Adsorption Carbon Dioxide Smectites
2011/11/18
Abstract: The adsorption of CO2 at low temperature (∼ −70°C) on thin films of homoionic smectites was studied by X-ray diffraction and by i.r. absorption. An increase in the d001 spacings ...

The surface areas obtained by application of the B.E.T. theory to adsorption isotherms of nitrogen and carbon dioxide gases at 77°K and 195°K respectively on homoionic samples of illite and montmorill...
Surface Area of Vermiculite with Nitrogen and Carbon Dioxide as Adsorbates
Surface Area Vermiculite Nitrogen Carbon Dioxide Adsorbates
2012/2/20
Surface-area studies were made on several homoionic vermiculites with both nitrogen and carbon dioxide as adsorbates. These studies show that only very slight penetration occurs between individual ver...
