    • Richard J. Block + 2 más
    • Inglés
    A Manual of Paper Chromatography and Paper Electrophoresis provides a comprehensive discussion of the techniques of paper chromatography and paper electrophoresis. The book is organized into two parts. Part I on paper chromatography provides a readily accessible source for some of the many uses and adaptations of paper chromatography. An effort has been made to write a practical manual in which tried and proved procedures, employing relatively simple equipment and available reagents, are summarized. Part II on paper electrophoresis discusses basic principles and methodology. The emphasis throughout has been on the separation of protein mixtures, particularly blood serum. This reflects the fact that it is in this particular application that paper electrophoresis has thus far not been challenged by paper chromatography, whereas many of the smaller molecules can be resolved equally well or better by the thus far more widely employed chromatographic procedures.

  • The Physical Basis of Chemistry

    • 1 Edición
    • Warren S. Warren
    • Inglés
    If the descriptive text youre using for teaching general chemistry seems to lack sufficient mathematics and physics to make the results of its presentation of classical mechanics, molecular structure, and statisticsunderstand... youre not alone. Written to provide supplemental and mathematically challenging topics for the advanced lower-division undergraduate chemistry course, or the non-major, junior-level physical chemistry course, The Physical Basis of Chemistry will offer your students an opportunity to explore quantum mechanics, the Boltzmann distribution, and spectroscopy in a refreshingly compelling way.Posed and answered are questions concerning everyday phenomena: How can two discharging shotguns and two stereo speakers be used to contrast particles and waves? Why does a collision between one atom of gas and the wall of its container transfer momentum but not much energy? How does a microwave oven work? Why does carbon dioxide production heat the earth? Why are leaves green, water blue, and how do the eyes detect the difference? Unlike other texts on this subject, however, The Physical Basis of Chemistry deals directly with the substance of these questions, avoiding the use of predigested material more appropriate for memorization exercises than for actual concrete learning. The only prerequisite is first-semester calculus, or familiarity withderivatives of one variable.

  • Experimental Chemotherapy

    • 1 Edición
    • R. J. Schnitzer + 1 más
    • Inglés
    Experimental Chemotherapy, Volume I, attempts to condense the existing knowledge in the broad field of experimental chemotherapy in a comprehensive form. The arrangement of the subject matter follows a plan by which the not always avoidable repetitive description is reduced to a minimum. In most of the protozoan and metazoan infections it appeared advantageous to discuss the different series of active compounds according to the specific diseases and their causative agents. In other cases, owing to the wide range of activity of certain antibacterials, the material is arranged according to the groups of compounds. This first volume deals with infections caused by parasites, both protozoan and metazoan; it also contains general chapters on history of chemotherapy, toxicology, statistics, and drug resistance. It is hoped that the treatise will be useful to experimental workers engaged in the search for new chemotherapeutic remedies and in the study of their mechanism of action; to all who are involved in the teaching of pharmacology and therapeutics; and to physicians and veterinarians interested in the experimental basis of the drugs they are using.

    • A. Bruylants + 2 más
    • Inglés
    Organic Synthesis is a collection of papers dealing with synthetic tools, the effect of pressure on the electronic states of organic solids, and some novel approaches to alkylations. Some papers explain the cyclopropanation of silyl enol ethers and the two-phase reactions in the chemistry of carbanions and halocarbenes as useful tools in organic synthesis. One paper investigates the "biogenetic-type" synthesis of the bicyclic penicillin-cephalosp... antibiotics from an acyclic tripeptide equivalent. Another paper explains the advantages of the two-phase system to generate trihalomethylanions and dihalocarbenes as it allows the investigator to carry out all the reactions typical for these species easily. The system also readily applies to the reactions of some carbanions with aromatic nitrocompounds. Thallium(III) nitrate (TTN) can be used as an oxidant in organic synthesis; reactions that follow it use include the oxidations and oxidative rearrangements of olefins, acetylenes, ketones and compounds containing carbon-nitrogen double bonds. Another paper presents some examples that use singlet oxygen in synthetic organic chemistry. This collection is useful for researchers, technicians, and scientists whose works involve organic chemistry, analytical chemistry, and other related fields of chemistry, such as physical chemistry and inorganic chemistry.

  • Luminescence and the Solid State

    • 1 Edición
    • Volumen 12
    • Richard C. Ropp
    • Inglés
    Since the discovery of the transistor in 1948, the study of the solid state has been burgeoning. Recently, cold fusion and the ceramic superconductor have given cause for excitement. There are two approaches possible to this area of science, namely, that of solid state physics and solid state chemistry, although both overlap extensively. The former is more concerned with electronic states in solids (including electromagnetics) whereas the latter is more concerned with interactions of atoms in solids. The area of solid state physics is well documented, however, there are very few texts which deal with solid state chemistry. Luminescence and the Solid State has been written to fulfil this need. The concepts regarding luminescence and phosphors are unique and have been covered extensively providing a useful reference source for anyone requiring such knowledge as a basis for further study. The discussion on the defect state, which is handled in chapter two, can be applied to many other systems, e.g. ceramic superconductors. The book has extensive, useful equations and figures, the derivations of which are simple and easy to follow. This useful, comprehensive text can be used for self-study and should also prove invaluable in a graduate study as an introduction to the solid state and luminescence.

  • Handbook of Hydrocarbons

    • 1 Edición
    • S. W. Ferris
    • Inglés
    Handbook of Hydrocarbons presents tables giving the most important physical properties of all hydrocarbons whose boiling points have been recorded, in such form that all compounds boiling at or near a given value are listed together and a specific hydrocarbon can be promptly located. These ends can be best accomplished by listing each hydrocarbon in each of two tables. The order in Table A is that of the boiling points at 760 mm Hg, and other properties are also given. In Table B, the compounds are in groups of the same empirical formula and same type and are arranged within groups alphabetically by parent compound. Table C lists alternate names, including common and trivial names, and Table D gives the numbering of representative cyclic hydrocarbons. The Handbook should offer real help to any investigator who wishes either to locate the properties of a specific hydrocarbon, or to obtain a quick summary of the indications which the literature affords as to what compounds may be present in a cut of known boiling point or range. Such investigators should include academic, institutional, government and industrial workers, not only in the predominantly hydrocarbon fields such as petroleum, natural gas, shale oil, coal, and rubber, but also in the chemical, ""petrochemical,"" and plastics fields.

  • Structure of Matter

    With Contributions in Memoriam Including a Complete Bibliography of His Works

    The Collected Works of Irving Langmuir: Volume 6, Structure of Matter deals with the research work of Irving Langmuir in the field of thermionics, gaseous discharge, and on the structure of atoms with emphasis on valence. Some of the paper he writes on the subject of atomic structure are: "The Structure of Atoms and the Octet Theory of Valence," "The Arrangement of Electrons in Atoms and Molecules," and "The Octet Theory of Valence and its Applications with Special Reference to Organic Nitrogen Compounds." He challenges the complexities of valence theory and atomic structure, leading to a complete change of the theoretical structure of the subject of chemistry. Langmuir also works on molecules and crystalline structures, and applies the structures of crystals to check and confirm his own theories on molecular structure. His assumption that "the force between molecules in contact can be considered as caused by a surface energy proportional to the area over which the molecules are in contact" provides a solid foundation for explaining the properties of many chemical substances. Chemists, students, academicians, scientists, and general readers interested in the lives of great men in science will find this book very informative.

    Biosynthesis of Aromatic Compounds is a collection of papers from the Proceedings of the Second Meeting of the Federation of European Biochemical Societies in Vienna, on April 21-24, 1965. This volume is based on lectures given at the symposium and covers the studies made on the biosynthesis of aromatic compounds. The first part discusses the biosynthetic intermediates in polyketide biosynthesis in connection with the biosynthesis of fatty acids; it also notes the biosynthesis of coumarins that form from derivatives of carbohydrate metabolism. Other results concerning the biosynthesis of benzoic acids and on compounds such as substituted benzaldehydes and benzylalcohols are presented. Another paper shows that when species of mycobacteria are grown under iron-deficient conditions, salicylic acid can be produced. The second part focuses on studies made on the biosynthesis of aromatic compounds that contain hetero atoms. The formation of aromatic systems in alkaloids and the biosynthesis of some alkaloids based on aromatic precursors are analyzed. The book explains that some flavor compounds such as mustard oils are the product of enzymatic hydrolysis of thioglucosides, and then notes that the biogenetic schemes of Mentzer et al. concerning another study are not suitable as working hypotheses. This collection can be read profitably by chemists, biochemists, and academicians involved in aromatic compound researches.
