Graphs of operating potential versus current density are called polarization curves, which reflect the degree of perfection that any particular fuel cell technology has attained. High cell operating potentials are the result of many years of materials optimization. Actual polarization curves will be shown below for several types of fuel cell.

The second step of the nonlinear material optimization process will be detailed in the cases of three efficient nonlinear materials recently developed at CNET POM, MAP and NPP. For all these materials specific features were implemented at the molecular level so as to act on the crystalline structure in the required direction (i.e. away from centrosymmetry and toward an "optimal" crystalline structure which has been theoretically defined O, 4) and actually almost reached in the case of NPP. 

Comparison of the results allows calculation of kj6/ki8. Obviously there are drawbacks to this procedure. The major one is the necessity of a costly and tedious isotopic synthesis of labeled materials. Optimally those compounds should be as close as possible to 100% enriched. This can seldom be achieved and using partially enriched samples requires substantial corrections to the raw data and increases experimental uncertainty. A rule of thumb used in remote labeling experiments is that the remote (reporting) position should be reasonably far from the reaction center (the phenolic oxygen in the present example). For the case where there is no isotope effect at the reporting site (e.g. no 15N-KIE), the double-label experiment leads directly to the isotope effect of interest. This is more probable when the reporting site is remote, (i.e. well isolated from the reaction coordinate). 

Since the issue of order/disorder versus (or with) displacive aspects has remained an active field of research, most of the chapters presented in this book are devoted to it. In addition, new fields of applications are reviewed, since material optimization has considerably enlarged this area. A new aspect of ferroelectricity has been discovered recently by the finding of isotope-induced ferroelectricity in the quantum paraelectric SrTiOa. Here conclusive ideas about its microscopic origin are still missing and also the experimental situation remains controversial, since the symmetry of the low-temperature phase is unclear. But, there seems to be stringent evidence that polar clusters are... 

If the stopper is as small as technically possible and its material optimized, the water content of the stopper depends on its prehistory Steam-sterilized stoppers take up water (e.g. 1.1% of their weight), which can only be removedby 8 h of vacuum drying...

Because the influence of drying parameters is not the same for all materials, optimal drying conditions vary depending on the final objective volatile retention, preservation of enzymatic activity and avoidance of protein denaturation, fat oxidation or crystallisation. Furthermore, some interactive influences may appear between components, an effect that is positive for protection of labile compounds by a network of polymers as polysaccharides, gums, proteins (Dumoulin and Bimbenet 1998). The phenomena may vary between centre and surface of drops, with some possible segregation by internal movement in the drop. 

With reference to Eq. (7), in most situations the holographic index contrast increases quadratically with the dipole moment of the chromophore. The dipole moment thus provides a parameter for material optimization, albeit at the expense of increased disorder slowing down charge transport. Transport rate appears not to be critical, however.

Dr. Hamish Fraser at Ohio State University directs a project intended to develop modeling tools that will predict material properties for a set of components critical to the operation of aircraft gas turbine engines. The properties of interest are low cycle fatigue and fatigue crack growth. Expected outcomes of this research not only will effect an acceleration of the materials optimization and insertion process but also will play a major role in the reduction of costs associated with extension of component life.
