Among the high-temperature superconductors one finds various cuprates (i.e., ternary oxides of copper and barium) having a layered structure of the perovskite type, as well as more complicated oxides on the basis of copper oxide which also include oxides of yttrium, calcium, strontium, bismuth, thallium, and/or other metals. Today, all these oxide systems are studied closely by a variety of specialists, including physicists, chemists, physical chemists, and theoreticians attempting to elucidate the essence of this phenomenon. Studies of electrochemical aspects contribute markedly to progress in HTSCs. [Pg.630]

The well-known tetrahedral [Co(NCS)4]2 ion has continued to attract attention from analytical chemists, physical chemists, and spectroscopists. The inelastic electron tunneling (IET) spectrum of (Me4N)2[Co(NCS)4] was compared with IR and Raman spectra of the same complex.359 The vibrational bands due to the Me4N+ were prominent in all three spectra, but Coligand stretches were absent from the IET spectra. The lowest 4 42 4T2 electronic transition was strong in the IET spectrum but absent from the IR spectrum. The electric dipole allowed 4A2 4TX electronic transition was observed in both the IET and IR spectra and no fine structure was observed. Complex formation equilibria between Co11 and SCN- were studied calorimetri-... [Pg.38]

Chemists are frequently grouped into subcategories to distinguish their area of expertise. Five large chemical specialties into which many chemists may be classified are inorganic chemist, organic chemist, physical chemist, biochemist, and analytical chemist. Inorganic chemists work with noncarbon-based compounds and frequently work in areas such as solid-state electronics,... [Pg.327]

Hphe term anomeric effect was introduced by Lemieux in 1958 as a result of a detailed study of the anomerization of acetylated pento-and hexo-pyranoses. The effect is well known to carbohydrate chemists, and refers to the tendency of an electronegative substituent at C-l of a pyranoid ring to assume the axial rather than equatorial orientation, in contrast to predictions based solely on steric grounds. However, the phenomenon is not restricted to carbohydrate systems, but is displayed in many types of heterocyclic compounds. Thus, the investigation of the anomeric effect has been of considerable interest to a variety of chemists, namely, theoreticians, structural chemists, physical organic chemists, and synthetic chemists. Chemists from all of these areas participated in the Symposium on The Origin and Consequences of the Anomeric Effect. This symposium was the first symposium devoted exclusively to a discussion of the anomeric effect, and it provided a mechanism for interactions between the diverse types of chemists. The chapters in this volume are not merely the texts as presented at the symposium, but they also incorporate some new interpretations by the authors resulting from these interactions. [Pg.7]

Figure 3.109 shows a general scheme combining distinct disciplines in TP photosciences. It demonstrates the interdisciplinary cooperation needed to become an accepted scientific field in both academic and industrial areas. It demonstrates the workflow, starting from basic research including theory, synthesis, and chromophore characterization. Development of TP chromophores, materials needed for TP application, and methods and equipment required in TP photosciences will require interdisplinary work by theoretical scientists, organic chemists, polymer chemists, physical chemists, and physicists. [Pg.329]

The first section of this book covers liquids and. solutions at equilibrium. I he subjects discussed Include the thcrmodvnamics of solutions, the structure of liquids, electrolyte solutions, polar solvents, and the spectroscopy of solvation. The next section deals with non-equilibrium properties of solutions and the kinetics of reactions in solutions. In the final section emphasis is placed on fast reactions in solution and femtochemistry. The final three chapters involve important aspects of solutions at interfaces. Fhese include liquids and solutions at interfaces, electrochemical equilibria, and the electrical double layer. Author W. Ronald Fawcett offers sample problems at the end of every chapter. The book contains introductions to thermodynamics, statistical thermodynamics, and chemical kinetics, and the material is arranged in such a way that It may be presented at different levels. Liquids, Solutions, and Interfaces is suitable for senior undergr.iduates and graduate students and will be of interest to analytical chemists, physical chemists, biochemists, and chemical environmental engineers. [Pg.622]

The main task, as the author sees it, is to draw the attention of specialists (analytical chemists, physical chemists, biochemists, medical scientists, etc.) who use GC to the wide possibilities of reaction GC, and to characterize the main methods involved in important trends and hence to promote the development of the practical use of chemical methods. [Pg.13]

This volume is intended for chemists, formulation chemists, physical chemists, biologists, food scientists, and research scientists involved in the synthesis, technology, properties, and application of new surfactants. Also, it is expected to serve as a reference source for graduate students or researchers in the fields of colloid and surface chemistry or chemical technology and engineering. [Pg.296]

G. Farben Laboratory in Ludwigshafen (1926-1932) at the University of Vienna (1932-1938) and at the Canadian International Paper Company in Hawkesbury, Ontario (1938-19 0) made it clear that systematic progress could only be espected if organic chemists, physical chemists and at least one physicist could be assembled into a team to conduct research from the monomer or monomers through the polymerization process and the characterization of the resulting material.s to the structure and properties of such final products as coatings, films and fibers. [Pg.123]

To accomplish the challenges for more knowledge and understanding critical to advanced polymer chemistry many disciplines must collaborate. Those include synthetic polymer chemists, physical and analytical chemists, engineers, mathematicians and computer scientists. Let me just dwell for a moment or two on the role of mathematicians and computers in our future. [Pg.34]
