CLEAN METHOD AND DEVICE FOR INCREASING CO2 CONCENTRATION IN AIRPROBLEM TO BE SOLVED: To provide means for increasing CO2 concentration in the air by extracting CO2 contained in moisture and releasing it into the air.NAKNO JINICHIRO中野 尽一郎...
Because the CO2 concentration in the atmosphere is positively correlated with the air temperature, while the net primary production is positively correlated with the CO2 concentration, and the net primary production is positively correlated with the niche quantity. Therefore, during the " Cold period"...

GENEVA, Aug. 30 (Xinhua) -- Swiss researchers have shown that during drier years the concentration of carbon dioxide in the atmosphere rises faster because stressed ecosystems absorb less carbon, which must be integrated in the next generation of climate models, the Swiss Federal Institute of Tech...
Intermittent or continuous monitoring of percent O2 in gas mixtures containing 0- CO2. 90% response is time is 45 seconds. Has more tolerance to exposure to air than A-3. No restrictions on CO2 concentration. B-1oxygen sensor C6689-B1 General purpose percent oxygen analysis where fast respons...
(Fig.2b). When the experiment was conducted in the dark, low O2concentration in the reaction remained unchanged and came from the residual air, which was not completely removed by the degassing procedure. By way of contrast, during the photocatalytic reaction, the concentration of O2increased ...
But the direct air capture (DAC) process, like the one in Iceland, aims to capture past emissions already in the atmosphere. 但是冰岛的这种直接空气捕集方法旨在捕获过去排放到大气中的二氧化碳。 However, the DAC method...
You might think it's your colleagues or the pressures of work that's getting you down at the office, but new research suggests it could well be the air you're breathing instead. Scientists in the US have found that the concentration of carbon dioxide inside the confined spaces we use ever...

The teams simulated high CO2 levels in open-air fields using a system called Free Air Concentration Enrichment (FACE), which pumps out, monitors and adjusts ground-level atmospheric CO2 to simulate future conditions. In this study, all other growing conditions (sunlight, soil, water, temperature...
