  • Weeds and What They Tell Us

    This wonderful little book covers everything you need to know about the types of plants known as weeds. Ehrenfried Pfeiffer discusses the different varieties of weeds, how they grow and what they can tell us about soil health. The process of combatting weeds is discussed in principle as well as in practice, so that it can be applied to any situation. First written in the 1950s, this is still one ... Read more

  • Sensitive Crystallization Processes

    A Demonstration of Formative Forces in the Blood

    Translated by Henry B. Monges ...
    Dr. Ehrenfreied Pfeiffer writes:"Research carried on since 1925 has shown that the formation and arrangement of crystals during the process of crystallization can, under certain conditions, be greatly influenced by the admixture of various substances.... Hence, from these alterations (in form) apriori conclusions can be drawn about the qualities and characteristics of the admixture itself."This is ... Read more

  • Group Theory Applied to Chemistry

    Series series Chemistry and Material Science (R0)
    Chemists are used to the operational definition of symmetry, which crystallographers introduced long before the advent of quantum mechanics. The ball-and-stick models of molecules naturally exhibit the symmetrical properties of macroscopic objects. However, the practitioner of quantum chemistry and molecular modeling is not concerned with balls and sticks, but with subatomic particles: nuclei and ... Read more

  • Symmetry Relationships between Crystal Structures

    Applications of Crystallographic Group Theory in Crystal Chemistry

    Series Book 18 - International Union of Crystallography Texts on Crystallography
    In crystal chemistry and crystal physics, the relations between the symmetry groups (space groups) of crystalline solids are of special importance. Part 1 of this book presents the necessary mathematical foundations and tools: the fundamentals of crystallography with special emphasis on symmetry, the theory of the crystallographic groups, and the formalisms of the needed crystallographic ...

  • The Nature of the Hydrogen Bond

    Outline of a Comprehensive Hydrogen Bond Theory

    Series Book 23 - International Union of Crystallography Monographs on Crystallography
    Hydrogen bond (H-bond) effects are known: it makes sea water liquid, joins cellulose microfibrils in trees, shapes DNA into genes and polypeptide chains into wool, hair, muscles or enzymes. Its true nature is less known and we may still wonder why O-H...O bond energies range from less than 1 to more than 30 kcal/mol without apparent reason. This H-bond puzzle is re-examined here from its very ... Read more

  • Nucleation Theory and Growth of Nanostructures

    Series series Chemistry and Material Science (R0)
    Semiconductor nanostructures such as nanowires are promising building blocks of future nanoelectronic, nanophotonic and nanosensing devices. Their physical properties are primarily determined by the epitaxy process which is rather different from the conventional thin film growth. This book shows how the advanced nucleation theory can be used in modeling of growth properties, morphology and crystal ... Read more

  • Thermodynamics of Crystalline States

    Series series Physics and Astronomy (R0)
    Originated from studies on steam engines, thermodynamics is formulated traditi- ally for homogeneous materials. Applying to condensed matters however, laws of thermodynamics have to be evaluated with respect to the structural detail. Foll- ing after Kirkwood’s chemical thermodynamics, the author’s attempt is to discuss lattice dynamics in crystalline states in light of the traditional laws. It is ... Read more
