Conventional configuration

Figure 1. Sketch of an electrochemical cell whose equilibrium (open circuit) potential difference is AE. (a) Conventional configuration and (b) short-circuited configuration with an air gap. M and R are the electrodes, S is the solvent (electrolyte solution). Cu indicates the cables connecting the two electrodes to a measuring instrument (or to each other).

Stacks in series approach reversibility. MCFC stack networks produce more power than conventional configurations because they more closely approximate a reversible process. To illustrate this fact, consider Figure 9-20, which compares the maximum power that could be generated by three different MCFC systems having identical feed stream compositions. ... 

The aim of our similarity-transformed Hamiltonian is to improve the computation of the correlation energy of conventional configuration-interaction (Cl) calculations. In this framework, the conventional wave function is multiplied by the correlation function 14,15,16)... 

This class of sensors is the easiest to build but prevents the development of miniaturizable sensors for in situ applications. In general, this conventional configuration represents an easy and rapid way to optimize the response characteristics of any recognition element, before any possible integration in...

From Eqs. 1 and 3, one can conclude that an increase in the membrane thickness leads to a proportional rise of sensitivity and a response time increase, related to the square of the membrane thickness, if a conventional configuration is used. 

For this reason, the most studied application has been the use of optically active pH indicators as H+-selective ionophores to develop pH-selective optical sensors [38]. First, the optical and analytical characteristics in PVC membranes of a series of novel neutral pH indicators, a class of keto cyanine dyes [144], were studied in a conventional configuration. The absorption maxima of the dyes are located in the NIR region, which is very appropriate for applications using telecommunications components and the membranes show good performance during calibrations in the pH range 3-8.5. 

To verify that the sensitivity increase is not related to the use of thicker membranes, the response times are calculated for both configurations and then compared. The results show that using the IWAO, the average of the response times calculated for every step change (usually 0.2 AU) are of the same order as or lower than the ones obtained using the conventional configuration. 

Mujtaba (1999) considered the conventional configuration of BED processes for the separation of binary close boiling and azeotropic mixtures. Dynamic optimisation technique was used for quantitative assessment of the effectiveness of BED processes. Two distinct solvent feeding modes were considered and their implications on the optimisation problem formulation, solution and on the performance of BED processes were discussed. A general Multiperiod Dynamic Optimisation (MDO) problem formulation was presented to obtain optimal separation of all the components in the feed mixture and the recovery of solvent while maximising the overall profitability of the operation. 

In addition to the above conventional configurations, there have been some novel designs proposed for various typxjs of inorganic membrane reactors. They will be discussed here. 

In the case of the oxidation of a metallic substrate the anodization depends strongly on the humidity of the adsorbed water molecules which is the working electrolyte. The anodization process is carried out in conventional configuration with the tip as the counter electrode and the metal substrate as the working electrode. The anodization takes place when the metallic substrate is biased positively with respect to the tip, which as mentioned before can be either the STM tip or the tip of a conducting AFM. 

In both cases, less initiator and soap are used than in the conventional configuration. 

Long Island Sound is connected to the sea by three passes at its eastern end and by the East River (through New York Harbor) at its western end. The principal source of fresh water entering the Sound is the Connecticut River, which enters near the eastern end, as shown in Fig. 11. Thus the Sound does not have the conventional configuration of an estuary with...

The relative calculational efficiency of EOM-Green s function methods and conventional configuration interaction methods is a difficult matter to assess, since it is intimately bound to the question of optimization of computer codes. Our major emphasis has been on determining the requirements for an accurate and reliable EOM theory. Of necessity, the program optimization has to an extent taken a back seat to the constant changes introduced in the theory in the course of this work. However, the demonstrated ability to obtain accurate results for the simple ionization potentials of small molecules with very small primary operator spaces bodes well for the EOM method. 

Degradation of organopollutants by fungal cultures has been carried out successfully at bench and pilot scale, preferentially in batch or semi-continuous operations (Alleman et al. 1995 Fujita et al. 2002 Mielgo et al. 2002). Continuous treatment systems are desirable alternatives to increase process efficiency. A modified conventional configuration (fixed-bed bioreactor) coupled with a pulsation system has... 

Let us see these two trajectories, recrossing the conventional, configurational dividing surface S(qj = 0), by projecting these onto the zeroth-, first-, and second-order new coordinate planes of q (p,q) and qii(p,q). Remember that the zeroth-order coordinate system (q , qT ) is the original normal eoordinate system (qj, q ). Figure 2.6 shows the projections onto a 2D subspace chosen from the nonreaetive eoordinates, ( " (p, q), 3s (p, q)), at both the energies.
