Development of a thermodynamic identification tool for CO2 capture by chemical absorption

15.10.2014 | Anthony Biget, Thibaut Neveux, Jean‐Pierre Corriou, Yann Le Moullec, The Canadian Journal of Chemical Engineering, 2014

Abstract The extended UNIQUAC model has been used for the representation of the thermodynamic behaviour of CO2 absorption in aqueous amine solutions. Based on available experimental data, an identification methodology has been developed to fit the extended‐UNIQUAC model parameters. In the ...

Hierarchically CdS Decorated 1D ZnO Nanorods‐2D Graphene Hybrids: Low Temperature Synthesis and Enhanced Photocatalytic Performance

13.10.2014 | Chuang Han, Zhang Chen, Nan Zhang, Juan Carlos Colmenares, Yi‐Jun Xu, Advanced Functional Materials, 2014

A simple, low‐temperature synthesis approach is reported for planting CdS‐sensitized 1D ZnO nanorod arrays on the 2D graphene (GR) sheet to obtain the ternary hierarchical nanostructures, during which graphene oxide (GO) as the precursor of GR acts as a flexible substrate for the formation of ...

The Solvation Structure of Mg Ions in Dichloro Complex Solutions from First-Principles Molecular Dynamics and Simulated X-ray Absorption Spectra

01.10.2014 | Liwen F. Wan; David Prendergast, Journal of the American Chemical Society, 2014

The knowledge of Mg solvation structure in the electrolyte is requisite to understand the transport behavior of Mg ions and their dissolution/deposition mechanism at electrolyte/electrode interfaces. In the first established rechargeable Mg-ion battery system [D. Aurbach et al. Nature 2000, 407, ...
