Clearly, the advantage of reducing EC coordination will not be overshadowed by an increase in DEC coordination, which is attributed to the intrinsically low polarity nature of DEC with respect to EC. On one hand, since EC is a high polar solvent, thus a decrease in the coordination number ...
State its formal charge and polarity. What is its molecular geometry? Draw the structures of IF_7. In addition, what would be the bond hybridization in the compound and would expect them to be stable? Draw the lewis structure for m N O 2 , including...
The larger the electronegative difference between the bonded atoms, larger is the magnitude of the dipole moment and hence more polar is the bond. All heteronuclear diatomic molecules (A-B. where A≠B) are polar molecules with the degree of polarity depending on the electronegativity differences b...
Phase selection and crystal orientation (i.e., the nucleating plane) of the growing crystal are determined by: (i) surface polarity; (ii) surface ordering/roughness; (iii) surface geometry/symmetry; and (iv) head group orientation due to even or odd chains. The concepts of template-induced...
Careful design and tuning of an amphiphilic molecular structure is essential in synthesising a thermogelling polymer such that the system is still able to hold water to form a gel at the desired temperature range. As such, the transition temperature at which gel formation occurs is an important...

The DFM method treats the fractures explicitly and can characterize the effect of each fracture on fluid flow and solute transport. Due to the complexity of fracture geometry, an unstructured mesh is needed. However, when the distance or the angle between the adjacent fractures is very small, ...
Simulations were conducted with the same parameter settings as the pilot reactor, including the reactor geometry, operating conditions and catalyst properties. Figure 3 shows the mass flow rates of the converted EC and the produced EG, MeOH and by-products measured in pilot plant run and those ...
A feasible solution to by-pass the thermodynamic limitation is to “bridge” the low-energy CO2 reactant and the high-energy MeOH product with a CO2-derivable, medium-energy intermediate, such as ethylene carbonate (EC), dimethyl carbonate, methyl formate, and so on [19,20,21,22,23]. Su...
