Metallamacromolecules offer opportunities to create structural diversity and interesting properties based on their unique frameworks and host-guest chemistry. Various types of assemblies can be created by the appropriate choice of the predesigned organic ligands containing various backbones and connectivity information and metal centers. These macrocyclic hosts contain a large and tunable hydro...

Organofluorine compounds have found widespread and growing use in the pharmaceutical, materials, and other industries.1 Transition metals offer great potential improvements in the scope, selectivity, and convenience of fluorination chemistry. Their use in C-F bond formation, however, has only begun to be explored.2 Examples to date include electrophilic fluorinations of arene2a and enol2b,c C-H...

For the situations considered, military forces are located in an underrdeveloped country during peacetime. Logistic support of these forces poses problems of many types. The simulation model described in this paper furnishes a method for quantitative investigation of these problems. Procedures are outlined for consideration of the many factors that are involved in a military logistics operation...

The enormous potential of parallel computing has led to the first prototype devices being constructed. However, all the examples to date rely on complicated chemical and/or physical manipulations, and hence do not lend themselves to the kind of widespread investigation necessary to advance the field. This article presents a new paradigm for parallel computing: the use of solid, single crystalli...
