Behaviour of carbon dioxide and water vapour flux densities from a disturbed raised peat bog [PDF]

open access: yes, 2002
Measurements of carbon dioxide and water vapour flux densities were carried out for a disturbed raised peat bog in the north of the Netherlands during an 18 month continuous experiment. Tussock grass (sp. Molinea caerulae) mainly dominated the vegetation

Osteogenic Effects of Ion Released from Biodegradable Metallic Magnesium and Calcium Coating

open access: yesAdvanced Biology, EarlyView.
This study explores how magnesium–calcium coatings on titanium promote osteogenesis by releasing ions and elevating pH during degradation. Using osteoblast‐like cells, the research demonstrates that both ion release and pH changes contribute to cell proliferation, differentiation, and mineralization, offering new insights into the design of bioactive ...

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 ...

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 ...
