Описание:
Solved and Unsolved Problems of Structural Chemistry introduces new methods and approaches for solving problems related to molecular structure. It includes numerous subjects such as aromaticity--one of the central themes of chemistry--and topics from bioinformatics such as graphical and numerical characterization of DNA, proteins, and proteomes. It also outlines the construction of novel tools using techniques from discrete mathematics, particularly graph theory, which allowed problems to be solved that many had considered unsolvable.
The book discusses a number of important problems in chemistry that have not been fully understood or fully appreciated, such as the notion of aromaticity and conjugated circuits, the generalized Hьckel 4n + 2 Rule, and the nature of quantitative structure-property-activity relationships (QSARs), which have resulted in only partially solved problems and approximated solutions that are inadequate. It also describes advantages of mathematical descriptors in QSAR, including their use in screening combinatorial libraries to search for structures with high similarity to the target compounds.
Selected problems that this book addresses include:
Multiple regression analysis (MRA)
Insufficient use of partial ordering in chemistry
The role of Kekulй valence structures
The problem of protein and DNA alignment
Solved and Unsolved Problems of Structural Chemistry collects results that were once scattered in scientific literature into a thoughtful and compact volume. It sheds light on numerous problems in chemistry, including ones that appeared to have been solved but were actually only partially solved. Most importantly, it shows more complete solutions as well as methods and approaches that can lead to actualization of further solutions to problems in chemistry.

Описание: A Practical Guide from Top-Level Industry Scientists As advanced teaching and training in the development of cementitious materials increase, the need has emerged for an up-to-date practical guide to the field suitable for graduate students and junior and general practitioners. Get the Best Use of Different Techniques and Interpretations of the Results This edited volume provides the cement science community with a state-of-the-art overview of analytical techniques used in cement chemistry to study the hydration and microstructure of cements. Each chapter focuses on a specific technique, not only describing the basic principles behind the technique, but also providing essential, practical details on its application to the study of cement hydration. Each chapter sets out present best practice, and draws attention to the limitations and potential experimental pitfalls of the technique. Databases that supply examples and that support the analysis and interpretation of the experimental results strengthen a very valuable ready reference. Utilizing the day-to-day experience of practical experts in the field, this book: Covers sample preparation issues Discusses commonly used techniques for identifying and quantifying the phases making up cementitious materials (X-ray diffraction and thermogravimetric analysis) Presents good practice oncalorimetry and chemical shrinkage methods for studying cement hydration kinetics Examines two different applications of nuclear magnetic resonance (solid state NMR and proton relaxometry) Takes a look at electron microscopy, the preeminent microstructural characterization technique for cementitious materials Explains how to use and interpret mercury intrusion porosimetry Details techniques for powder characterization of cementitious materials Outlines the practical application of phase diagrams for hydrated cements Avoid common pitfalls by using A Practical Guide to Microstructural Analysis of Cementitious Materials. A one-of-a-kind reference providing the do’s and don’ts of cement chemistry, the book presents the latest research and development of characterisation techniques for cementitious materials, and serves as an invaluable resource for practicing professionals specializing in cement and concrete materials and other areas of cement and concrete technology.
