Net Carbon Dioxide Exchange Rates and Predicted Growth Patterns in Alstroemeria `Jacqueline' at Varying Irradiances, Carbon Dioxide Concentrations, and Air Temperatures

Capturing Carbon Dioxide From Air

The goal of carbon sequestration is to take CO2 that would otherwise accumulate in the atmosphere and put it in safe and permanent storage. Most proposed methods would capture CO2 from concentrated sources like power plants. Indeed, on-site capture is the most sensible approach for large sources and initially offers the most cost-effective avenue to sequestration. For distributed, mobile source...

Carbon Dioxide Capture and Air Quality

Diamond formation by reduction of carbon dioxide at low temperatures.

This Communication reports a low-temperature diamond synthesis technique, in which diamonds (10-250 mum) can form at a temperature as low as 440 degrees C by reduction of dense CO2 with metallic Na. The X-ray diffraction pattern of a powder sample shows three reflection peaks, indexed with 111, 220, and 311, corresponding unambiguously to cubic diamond. The Raman spectrum of the product exhibit...

Exchange of Carbon Dioxide in the Pregnant

A B S T R A C T The exchange of carbon dioxide in the pregnant rhesus monkey has been studied quantitatively using sodium bicarbonate-j4C and applying the model of a system of seven compartments. The transfer rates among the various compartments, compartment sizes, and the rate of production of carbon dioxide by fetus and mother were determined with a computer programmed to fit the theoretical ...
