Utilization of ancient permafrost carbon in headwaters of Arctic fluvial networks [PDF]

, 2015
Northern high-latitude rivers are major conduits of carbon from land to coastal seas and the Arctic Ocean. Arctic warming is promoting terrestrial permafrost thaw and shifting hydrologic flowpaths, leading to fluvial mobilization of ancient carbon stores.

Tuning Organic Carbon Dioxide Absorbents for Carbonation and Decarbonation [PDF]

Scientific Reports, 2015
AbstractThe reaction of carbon dioxide with a mixture of a superbase and alcohol affords a superbase alkylcarbonate salt via a process that can be reversed at elevated temperatures. To utilize the unique chemistry of superbases for carbon capture technology, it is essential to facilitate carbonation and decarbonation at desired temperatures in an ...

Organic carbon in Mollisols of the world – a review

1st International Conference of Soil and Agriculture TOWARDS SOIL SUSTAINABILITY/9788372594570, 2023
Mollisols represent 29 % of agricultural land and they are considered to be one of the most fertile soils in the world. Here, we compare soil organic carbon (SOC) concentrations and pools of Mollisols for the globe, the USA and Poland, and review how differences are caused by climate, land use, and key environmental factors.

Green organic syntheses: Organic carbonates as methylating agents [PDF]

The Chemical Record, 2002
AbstractDimethylcarbonate (DMC) is a valuable methylating reagent that can replace methyl halides and dimethylsulfate in the methylation of a variety of nucleophiles. It couples tunable reactivity and unprecedented selectivity towards mono‐C‐ and mono‐N‐methylation.
