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.

Carbon···Carbon Weak Interactions
The Journal of Physical Chemistry A, 2009 A theoretical study of the complexes formed by systems with electron-deficient and electron-excessive carbon atoms was carried out using DFT and ab initio methods up to the CCSD(T)/aug-cc-pVTZ computational level. Stable complexes with interaction energies between -6.0 and -22.8 kJ mol(-1) were obtained that correspond to weak C...C interactions.

A carbon–carbon hybrid – immobilizing carbon nanodots onto carbon nanotubes
Chemical Science, 2015 The thrust of this work is to integrate small and uniformly sized carbon nanodots (CNDs) with single-walled carbon nanotubes of different diameters as electron acceptors and electron donors, respectively, and to test their synergetic interactions in terms of optoelectronic devices.

Journal of Magnetic Resonance (1969), 1985 Nowadays many possibilities exist to elucidate carbon-carbon connectivity. In hydrogen-bearing carbon systems C-C connectivities can be traced out most conveniently in an indirect way by a combination of H-H COSY (I) and H-C CQSY (2). In case of overlapping ‘proton signals ambiguities can be removed by heteronuclear relayed spectroscopy (3) and ...

Carbon Emission Reduction—Carbon Tax, Carbon Trading, and Carbon Offset [PDF]
Energies, 2020 The Paris Agreement was signed by 195 nations in December 2015 to strengthen the global response to the threat of climate change following the 1992 United Nations Framework Convention on Climate Change (UNFCC) and the 1997 Kyoto Protocol [...]
