Mineral carbonation from metal wastes: Effect of solid to liquid ratio on the efficiency and characterization of carbonated products [PDF]
, 2014 Mineral carbonation technologies aim at permanently storing CO2 into materials rich in metal oxides. A multi-step mineralization process employing Ca-rich waste streams to precipitate calcium carbonate is investigated in this paper.

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 ...

Instantaneous Capture and Mineralization of Flue Gas Carbon Dioxide: Pilot Scale Study [PDF]
, 2010 Multiple CO2 capture and storage (CCS) processes are required to address anthropogenic CO2 problems. However, a method which can directly capture and mineralize CO2 at a point source, under actual field conditions, has advantages and could help offset ...
