The good permeability of CO2 through the Pure Matrimid and all of the three MMMs may be attributed to the smaller kinetic diameter of CO2, its polar nature, and creation of significant interactions between the CO2 molecules and the polar groups present in the Matrimid structure. These are the ...
they generally suffer from low permeability resulting from limited layered spacing and pore size18,19,20. Most of these 2D nanosheet-based membranes can only successfully achieve the separation of one or two of the three important binary gas mixtures; CO2/H2, CO2/N2and CO2/CH4. In...
brine solutions. Therefore, the results of the developed models can be more comprehensive and reliable for use in the cases mentioned at the beginning of the introduction. To develop the models, temperature, pressure, ionic strength of aqueous solutions, CO2mole percent in gaseous mixture, and the...

There are several factors that bolster the photovoltaic properties of metal halide perovskites, such as their high symmetry, the periodicity of their crystal structure (commonly referred to as 1D, 2D, or 3D perovskites), the arrangement of their polar organic cations, the ionic energy of their ha...
In general, CO2solubility can be enhanced by employing organic solvents instead of aqueous solutions as electrolytes. Despite CO2being a nonpolar molecule, it exhibits considerable polarizability and can form hydrogen bonds with compatible donor solvents. The majority of organic electrolytes are polar solv...
This self-crosslinking mode was completely different from other cross- linking modes involving added crosslinker due to the strong covalent bonds (polar cova9-of 18 lent bonds, coordinate covalent bonds, etc.,). Crosslinking via chelating bonds is a unique and innovative crosslinking mode [43]....
Thus, CO2 is a nonpolar molecule that resides in a gaseous state under P and T standard conditions because of the weak van der Waals interactions established between the molecules themselves. In addition, due to its null polarity, CO2 has a low diffusion coefficient in polar solvents (1.26 ×...
The results show that the reaction has proceeded well in DMF or DMSO, while it did not take place in nonpolar solvents (toluene) and aprotic polar solvents (acetonitrile). However, only a low product yield is obtained in a polar protic solvent (methanol), while moderate product yield is ...
