Design of Microstructure

Brow (1989) demonstrated ion-beam effects on the composition and structure of glass surfaces. These results are also very important for glass-ceramic investigations.

The determination of properties should provide information and some scientific conclusions helpful in further designing and improving glass-ceramics. Based on the results of even preliminary properties, new insight generally suggests changes in the chemical composition or directions in modification of the microstructure.

Besides the mass transfer coefficient, pressure drop plays an important role in the design of microstructured devices. The discussion here is focused on Taylor flow and annular flow. 

For the optimization of microstructure and a material system in formation of the percolation structure, many experimental works on observation of microstructure and evaluation of properties in composites are necessary. In this sense, computer simulation is considered to be a promising method for the estimation of properties and functions from design of microstructure in composites. The purpose of this study is the investigation of two-dimensional computer simulation to design percolation structure of the second phases with different aspect ratios. That is to clarify the relation between formation of percolation structure, the morphology and the configuration of the second phase. 

Nafion, a polymer known to form hydrophilic and hydrophobic domains ( ), was shown by Buttry and Anson to transport electrons partially by "single-file diffusion of electroactive species as they competed for ion-exchange sites within the polymeric film ( ). The heterogeneity of Nafion domains is important in applications such as the electrocatalytic system described above, and represents one of the earliest moves toward architectural design of microstructures at the surfaces of electrodes (vide infra). 

Results described above show that it is possible to control or monitor electron transfer that occurs among electroactive sites on non-electronically conductive surfaces. This knowledge may be exploited in the future design of microstructures, as well as in understanding electron transfer at surfaces, such as biological membranes. 

In this section, all simulation results have been analyzed to understand the potential impact of the flow phenomena/structures on the future reactor design of microstructured membrane-assisted FBRs. 

All the different aspects of the processing and properties of superalloys, including monocrystals, are systematically set out in chapters of an impressive book (Tien and Caulfield 1989). The latest subtleties in the microstructural design of monocrystal superalloys are set out by Mughrabi and Tetzlaff (2000) among other new insights, it now appears that the optimum misfit between the two major phases is not exactly zero.

Since its discovery more than 50 years ago, olefin metathesis has evolved from its origins in binary and ternary mixtures of the Ziegler-Natta type into a research area dominated by well-defined molecular catalysts. Surveys of developments up to 1993 were presented in COMC (1982) and COMC (1995). Major advances in ROMP over the last 10 years include the development of modular, stereoselective group 6 initiators, and easily handled, functional-group tolerant ruthenium initiators. The capacity to tailor polymer functionality, chain length, and microstructure has expanded applications in materials science, to the point where ROMP now constitutes one of the most powerful methods available for the molecular-level design of macromolecular materials. In addition to an excellent and comprehensive text on olefin metathesis, a three-volume handbook s has recently appeared, of which the third volume focuses specifically on applications of metathesis in polymer synthesis.
