Other Topics of Interest

The development of the electrodynamic balance and other particle traps has made it possible to perform precise measurements of the properties of small particles by focusing on the single particle. The variety of processes and phenomena that can be investigated with particle traps is quite extensive and includes gas/liquid and gas/solid chemical reactions, chemical spectroscopies, heat and mass transfer processes, interfacial phenomena, thermodynamic properties, phoretic forces, and other topics of interest to chemical engineers. 

Additionally, interesting investigations dealing with thermal stability of PFPE, as well as the effects of humidity and hydrocarbon contamination, have been examined in other studies [7,94-97,116]. Other topics of interest for PFPEs include chemical analyses [117-119], bonding mechanism of endgroups [84,120], molecular degradation [117-119,121-123], physical properties [105,124], and adsorption [125,126]. 

This section aims to show how the LFER approach compares to other property calculation methods. Biological, chemical, and physical responses originate from interactions between two or more molecules. Many of these interactions can be looked at as involving a solute molecule surrounded by solvent molecules. The successful application of solute-solvent interaction models to many such properties has been well documented. Examples of these properties include solubility, partition coefficients, rate constants, and biological activities, such as equilibrium binding constants, effective doses, and toxicities, as well as other topics of interest in medicinal chemistry. 

Other topics of interest include a study of the photophysics of the local anaesthetic dibucaine as a function of pH in aqueous media. " Photo-CIDNP studies have been made on the reactions of chlorpromazine and analogues with solvent. " The laser photolysis of 1-ephidrine shows ionization by biphotonic... 

This magazine has plenty of advice, stories, celebrity interviews, and other topics of interest for girls. 

Crystallography Online http //wwl.iucr.org/cww-top/crystal.index.html (accessed October 1, 2010). Provides links to current information concerning crystallography and other topics of interest to crystallographers. This site is part of the International Union of Crystallography. 

A client can research the above topics by using publicly available data sources or commercial data collection services to obtain details about a site. The commercial data collection services can compile public records of remediation activities, citations, or fines from governmental entities and other data of interest for any property. Examples of these types of firms are Vistainfo, lAO Environmental Services and Lexis/Nexis. 

The impetus for this volume came from the symposium, and many of the presentations from that symposium are represented here as chapters or parts of chapters. To broaden the scope of this volume, other individuals were invited to contribute chapters relating to their own topic of interest. Our chief objective is to provide, for chemists, materials scien-tists/technologists, and the science and engineering community in general, an overview of this emerging new subdiscipline of chemistry. 

The present volume, the thirty-fourth in the series, surveys research on organic reaction mechanisms described in the literature dated December 1997 to November 1998. In order to limit the size of the volume, we must necessarily exclude or restrict overlap with other publications which review specialist areas (e.g. photochemical reactions, biosynthesis, electrochemistry, organometallic chemistry, surface chemistry and heterogeneous catalysis). In order to minimize duplication, while ensuring a comprehensive coverage, the Editors conduct a survey of all relevant literature and allocate publications to appropriate chapters. While a particular reference may be allocated to more than one chapter, we do assume that readers will be aware of the alternative chapters to which a borderline topic of interest may have been preferentially assigned. 

This topic is well covered by the contributions in this volume. CMP continues to be viewed as a surprisingly unique and flexible semiconductor fabrication technology by virtue of its ability to make manufactureable potential fabrication sequences that are either too cumbersome or too low in yield to be fabricated in any other manner. Using virtually any CMP polisher, a variety of materials of interest to IC fabricators can be planarized. These materials include insulators, semiconductors, interconnect metals, and barrier metallurgies. This means that once a user becomes adept in polishing one kind of material, typically oxide and W at first, other materials of interest and other semiconductor processing sequences become viable. 

The M-NM transition has been a topic of interest from the days of Sir Humphry Davy when sodium and potassium were discovered till then only high-density elements such as Au, Ag and Cu with lustre and other related properties were known to be metallic. A variety of materials exhibit a transition from the nonmetallic to the metallic state because of a change in crystal structure, composition, temperature or pressure. While the majority of elements in nature are metallic, some of the elements which are ordinarily nonmetals become metallic on application of pressure or on melting accordingly, silicon is metallic in the liquid state and nonmetallic in the solid state. Metals such as Cs and Hg become nonmetallic when expanded to low densities at high temperatures. Solutions of alkali metals in liquid ammonia become metallic when the concentration of the alkali metal is sufficiently high. Alkali metal tungsten bronzes... 

The main topic of interest is the properties of molecules of finite size, having no large rings, and in general having trifunctional branch-points. These are typically produced by chain-transfer with polymer in free-radical polymerizations, though they can of course be made in other ways. Molecules with branch-points of higher functionality are also of interest, especially star-shaped molecules with several arms, as these are both easy to synthesize and relatively easy to discuss theoretically. 

Since his arrival at McMaster in 1988, Randall Dumont has focused on statistical theories and their origin in quantum and classical mechanics. His interests include the development of Monte Carlo implementations of statistical theory wherein dynamical processes are simulated by random walks on potential energy surfaces. The breakdown of statistical theory and the appearance of nonexponential population decay are also topics of his ongoing investigations. Other questions of interest are the incorporation of quantum effects into statistical theory and the effects of collisions on reaction processes. He has a special interest in argon cluster evaporation in vacuum197 and in the description of simple isomerization reactions.198 His other interests include the semiclassical description of classically unallowed processes such as tunneling.199... 

Heat and mass transfer, especially mass transfer, in multiphase systems are problems commonly encountered in processing units in the chemical, petrochemical, and many other process industries. Because transfer rates significantly affect the efficiencies and technical-economic indexes of the processes, the enhancement of transfer has been a continuing topic of interest in chemical engineering since the late 1930s. A vast number of theoretical and experimental investigations have been carried out in the search for new methods of enhancing transfer between phases. 

Perkin s discovery was important not simply because he found a new and very useful dye. In the first place, Perkin (in collaboration with his father) opened a chemical factory to manufacture mauve on a large scale. The business was so successful that the younger Perkin was able to retire from the business in 1874, at the age of 35, to devote himself full time to chemical research on topics of interest to him. Second, Perkin s success inspired many other chemists in Great Britain and on the Continent to look for other potentially lucrative synthetic dyes. Over the next decade, a host of such dyes... 

Systems approach borrowed from the optimization and control communities can be used to achieve various other tasks of interest in multiscale simulation. For example, Hurst and Wen (2005) have recently considered shear viscosity as a scalar input/output map from shear stress to shear strain rate, and estimated the viscosity from the frequency response of the system by performing short, non-equilibrium MD. Multiscale model reduction, along with optimal control and design strategies, offers substantial promise for engineering systems. Intensive work on this topic is therefore expected in the near future.
