Design structural chemistry

Computational techniques in organic chemistry such as for drug design, structure elucidation or synthesis planning quite often investigate enormous numbers of hypothetical molecules, which are not yet... 

Structural chemistry is an essential part of modern chemistry in theory and practice. To understand the processes taking place during a chemical reaction and to render it possible to design experiments for the synthesis of new compounds, a knowledge of the structures of the compounds involved is essential. Chemical and physical properties of a substance can only be understood when its structure is known. The enormous influence that the structure of a material has on its properties can be seen by the comparison of graphite and diamond both consist only of carbon, and yet they differ widely in their physical and chemical properties.

The relative simplicity and low cost of STM instrumentation has contributed significantly to the rapid increase in the number of in situ electrochemical studies performed over the last decade. An excellent discussion of the general aspects of STM design and construction is available in a recent textbook [39], Beyond instrumentation, insightful experiments depend on the preparation of a flat, well-defined substrate and the formation of a stable tip capable of atomically resolved imaging. In this sense, the ability to reliably produce high-quality noble metal electrodes outside UHV has been central to the success of many STM studies [145-148]. In contrast, our knowledge of the structure, chemistry, and operation of the probe tip may be more aptly viewed as an art form. 

The wide range of possible compositions of LDHs means that materials with a great variety of different properties can be produced. A detailed understanding of the structural chemistry of LDHs as well as the kinetics and mechanism of the formation process should facihtate the design of materials with properties precisely tailored for specific apphcations. In the final chapter of this volume, Li and Duan review current and potential applications of LDHs in this light.

Although there is an analogy in many aspects between the structural chemistry of heterometallic Au-Ag and Au-Cu compounds, the interest shown in recent years has resulted in a considerable increase in the structural diversity for the gold-silver species resulting from the different strategies used to obtain compounds with a pre-established design, but also due to many unexpected compounds.

Flavoproteins play varied roles as coenzymes in biochemical processes. They serve as key intermediates in electron transport between those systems, such as the cytochromes, that carry one electron at a time and the two-electron transfers involved in the redox chemistry of organic-substrate metabolism. Flavins such as FMN or FAD (Figure 2) are designed structurally and electronically to stabilize both one- and two-electron redox intermediates. Thus, the one-electron reduction of...

Almost all applications programming in chemistry, and structural chemistry in particular, is performed in the FORTRAN language and the molecular mechanics calculations for which this hardware/software design exercise was undertaken is no exception. There are two problems which must be solved in order to build a FORTRAN microcomputer system with good scalar and array computational performance and these are firstly, the design of an efficient scalar processor with a transparent FORTRAN interface to the hardware and secondly, the design of an efficient AFPP,...
