Electrostatics-based design

In the preceding sections it has heen demonstrated that metal coordination complexes often interact with common support surfaces via an electrostatic mechanism, as the sole mechanism or in combination with other mechanisms. 

Even when other mechanisms are operative, a master impregnation variable would appear to be solution pH, and in particular, final pH. The two main experiments of the SEA method, the pHinitiai-pHfinai plot and the pH-uptake survey might be used for many systems to diagnose the type of adsorption mechanism and to determine the optimal impregnation conditions. These features of the SEA method will be reviewed for a single metal catalyst system, and then applied to composite oxide surfaces for the synthesis of promoted and bimetallic catalysts.

The percentage of the total input of each trace metal which was shown to exit with the slag is given in Table IX. This result for the pilot plant is based on analyses of the outgoing streams. The gas stream analysis was obtained at the combustor outlet, which would correspond in a commercial plant to the inlet of the boiler. The gas would, however, be subsequently cleaned in an electrostatic precipitator and the collected particulates recycled to the converter to be turned into the slag in the case of a commercial plant. The estimation for a commercial plant is premised on use of an electrostatic precipitator designed for a commercial plant of which the outlet particulate concentration is 0.1 g/Nm3 dry gas. It is expected that more than 99.7% of the...

The conductor-like screening model (COSMO) is a continuum method designed to be fast and robust. This method uses a simpler, more approximate equation for the electrostatic interaction between the solvent and solute. Line the SMx methods, it is based on a solvent accessible surface. Because of this, COSMO calculations require less CPU time than PCM calculations and are less likely to fail to converge. COSMO can be used with a variety of semiempirical, ah initio, and DFT methods. There is also some loss of accuracy as a result of this approximation. 

Collectively, these thermal denaturation studies demonstrated that aPNAs bind to complementary ssDNA targets with high affinity and in a sequence-specific manner consistent with our proposed base-pairing model. Additional electrostatic and hydrophobic binding interactions can be incorporated into the aPNA design without affecting the primary Watson-Crick binding mode.
