Nature, 1949 CARBON dioxide has been used as a narcotic for invertebrate animals for many years ; but the nature of its action is not yet understood. It has recently come into prominence in the discovery of strains of Drosophila sensitive and resistant to carbon dioxide (reviewed by l'Heritier1).

Carbon Dioxide Angiography [PDF]
Seminars in Interventional Radiology, 2008 The algorithm for patients with renal insufficiency who require vascular imaging has recently changed in my hospital. Previously, the majority of these patients underwent magnetic resonance angiography (MRA) or occasionally computed tomographic angiography after prescan hydration and sodium bicarbonate infusion.

Blue Urea: Fertilizer With Reduced Environmental Impact
Frontiers in Energy Research, 2019 Synthetic nitrogen fertilizers such as urea are a necessity for food production, making them invaluable toward achieving global food security. Conventional manufacture of urea is conducted in centralized production plants at an enormous scale, with the ...

Nature Communications, 2022 Electroreduction of CO2 on single atom catalysts is often hindered by electron delocalization of the metal sites. To improve CO2 activation, here the authors functionalize the carbon support with cyano moieties, thereby attenuating metal-substrate ...

Interglacials, Milankovitch Cycles, and Carbon Dioxide [PDF]
, 2010 The existing understanding of interglacial periods is that they are initiated by Milankovitch cycles enhanced by rising atmospheric carbon dioxide concentrations. During interglacials, global temperature is also believed to be primarily controlled by carbon dioxide concentrations, modulated by internal processes such as the Pacific Decadal Oscillation ...

Southern Medical Journal, 1953 One hundred patients received carbon dioxide-oxygen therapy. There was no improvement in 25 per cent, slight but definite improvement in 27 per cent, marked improvement in 26 per cent and apparent recovery in 22 per cent, over the one to nine months following therapy covered by this report.

Cellulose-Supported Ionic Liquids for Low-Cost Pressure Swing CO2 Capture
Frontiers in Energy Research, 2017 Reducing the cost of capturing CO2 from point source emitters is a major challenge facing carbon capture, utilization, and storage. While solid ionic liquids (SoILs) have been shown to allow selective and rapid CO2 capture by pressure swing separation of

Thermophysical properties of liquid carbon dioxide under shock compressions: Quantum molecular dynamic simulations [PDF]
, 2010 Quantum molecular dynamic simulations are introduced to study the dynamical, electrical, and optical properties of carbon dioxide under dynamic compressions. The principal Hugoniot derived from the calculated equation of states is demonstrated to be well accordant with experimental results.

Geochemistry of silicate-rich rocks can curtail spreading of carbon dioxide in subsurface aquifers [PDF]
Nat. Commun. 5:5743 (2014), 2014 Pools of carbon dioxide are found in natural geological accumulations and in engineered storage in saline aquifers. It has been thought that once this CO2 dissolves in the formation water, making it denser, convection streams will transport it efficiently to depth, but this may not be so.
