Carbon for soils, not soils for carbon
Global Change Biology, 2023 AbstractThe role of soil organic carbon (SOC) sequestration as a ‘win‐win’ solution to both climate change and food insecurity receives an increasing promotion. The opportunity may be too good to be missed! Yet the tremendous complexity of the two issues at stake calls for a detailed and nuanced examination of any potential solution, no matter how ...

Carbon nanofibers based carbon–carbon composite fibers
Discover Nano, 2023 AbstractTextile grade polyacrylonitrile (PAN) was used as a precursor material for carbon fiber preparation. E-beam irradiated polyacrylonitrile grafted carbon nanofibers were dispersed in polyacrylonitrile solution (dissolved in dimethyl formamide).

Carbon Anode in Carbon History [PDF]
Molecules, 2020 This study examines how the several major industries, associated with a carbon artifact production, essentially belong to one, closely knit family. The common parents are the geological fossils called petroleum and coal. The study also reviews the major developments in carbon nanotechnology and electrocatalysis over the last 30 years or so.

Preparation, physical-chemical characterisation and cytocompatibility of calcium carbonate cements [PDF]
, 2006 The feasibility of calcium carbonate cements involving the recrystallisation of metastable calcium carbonate varieties has been demonstrated. Calcium carbonate cement compositions presented in this paper can be prepared straightforwardly by simply mixing

Sedimentology of reefal buildups of the Xiannüdong Formation (Cambrian Series 2), SW China
Journal of Palaeogeography, 2019 The reefs in the Xiannüdong Formation (Cambrian Series 2) are the oldest archaeocyathan–microbial bioconstructions in China, but the details of their microbial structures have not been previously described.

Methods for synthesizing diethyl carbonate from ethanol and supercritical carbon dioxide by one-pot or two-step reactions in the presence of potassium carbonate [PDF]
, 2009 Carbon dioxide sequestration was studied by synthesizing diethyl carbonate (DEC) from ethanol and CO2 under supercritical conditions in the presence of potassium carbonate as a base. The co-reagent was ethyl iodide or a concentrated strong acid.
