Cellulose-Supported Ionic Liquids for Low-Cost Pressure Swing CO2 Capture

open access: yesFrontiers 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

Attenuating metal-substrate conjugation in atomically dispersed nickel catalysts for electroreduction of CO2 to CO

open access: yesNature 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 ...

Carbon Storage and Carbon Dioxide Emission as Influenced by Long-term Conservation Tillage and Nitrogen Fertilization in Corn-Soybean Rotation [PDF]

open access: yes, 2012
Although agriculture is a victim of environmental risk due to global warming, but ironically it also contributes toglobal greenhouse gas (GHG) emission. The objective of this experiment was to determine the influence of long-termconservation tillage and ...

Insights into secondary reactions occurring during atmospheric ablation of micrometeoroids [PDF]

open access: yes, 2016
Ablation of micrometeoroids during atmospheric entry yields volatile gases such as water, carbon dioxide, and sulfur dioxide, capable of altering atmospheric chemistry and hence the climate and habitability of the planetary surface.

Alkali metal carbon dioxide electrochemical system for energy storage and/or conversion of carbon dioxide to oxygen [PDF]

open access: yes, 1993
An alkali metal, such as lithium, is the anodic reactant; carbon dioxide or a mixture of carbon dioxide and carbon monoxide is the cathodic reactant; and carbonate of the alkali metal is the electrolyte in an electrochemical cell for the storage and ...

The Effect of Carbon Dioxide Anaesthesia on Collembola [PDF]

open access: yes, 2017
Excerpt: In a contribution to the Michigan Entomologist by Snider, Shaddy and Butcher (1969), a method of carbon dioxide anaesthesia for some soil arthropods was described as an alternative to etherization which frequently gives rise to unpredictable ...
