Bøger i Landolt-Boernstein: Numerical Data and Functional Relationships in Science and Technology - New Series serien

Surface tension of liquids determine fundamental chemical and physical properties and applications. Cleansing agents, soldering agents, pharmalogical substances and biomechanical phenomena all rely on surface tensions and their deliberate modifications, so that a collection of reliable data will be of interest for users in science, research and engineering.This supplement volume contains surface tensions of non-electrolyte material systems, as well as surface tensions data of pure liquids and binary liquid mixtures at normal temperatures.

The present volume I/25H is providing new data (excitation energies, spin-parities, half-lifes, branching ratios, cross-sections, spectroscopic factors, etc.) for nuclei with atomic numbers Z ranging from 54 (Xe) to 105 (Db) published in 2013-2014, thus updating previous compilations provided in the Landolt-B├╢rnstein volumes I/25A-F. The data presented are collected from all kinds of nuclear reactions, including data for nuclei far from the stability line. Since the time of collection of data for the volumes I/25A-F many new data appeared from new measurements and evaluations. The properties of excited nuclear states are of importance for scientific and practical applications. No systematic compilation of such data has been performed so far. The present compilation has been prepared by two eminent experts in the field. One of the characteristics of Landolt-B├╢rnstein is that data are evaluated before they are accepted for compilation. The idea is to present ΓÇÿbest valuesΓÇÖ which can be used with confidence by non-experts. In view of the large amount of data availablesome of the information is given only on the online platform SpringerMaterials.

The storage of electric energy depends on the capacity of the associated electrical components. The material''s dielectric constant directly governs this capacity. Dielectric constants therefore gain renewed attention with the increasing need of saving, accumulating and delivering energy produced in the most various ways (wind energy, solar energy, feed-back energy etc.).This supplementary volume contains static dielectric constants as a function of temperature, and - for the binary mixtures - as a function of composition.The focus lies on non-electrolyte systems and pure and binary liquid mixtures at normal pressure.

The objective of this volume is to present a full and critical spectral data coverage of the entire major fields relating to tetraphenyl and analogous porphyrins, their precursors, catabolic derivatives, and related systems electronically.The porphyrins are an important class of naturally occurring macro cyclic compounds that play a very important role in the metabolism of living organisms. They have a universal biological distribution and were involved in the oldest metabolic phenomena on earth. Without porphyrins and their relative compounds, life as we know it would be impossible and therefore the knowledge of these systems and their excited states is essential in understanding a wide variety of biological processes, including oxygen binding, electron transfer, catalysis and the initial photochemical step in photosynthesis.

Faujasite type zeolites have a wide range of industrial applications as ion exchanger, sorption agent, molecular sieve and as a catalyst, due primarily to their excellent structural stability, large and accessible pore volume, high activity, high resistance to nitrogen compounds and high regenerability.

These tables are preceded by an additional index in order to facilitate the search for specific information.The tables report molecular constants and/or, below about 5000 cm-1, assigned experimental line positions, intensities, and shape related parameters.

Thermodynamics determines the properties and region of existence of any alloy. Phase diagrams are of utmost importance as overviews of the particularities of any alloying mixture. The present volume presents phase equilibria, thermodynamic and crystallographic data of the binary alloys K-O ...

Electrochemistry is the basis of many important and modern applications and scientific developments such as nanoscale machining, electrochemistry at the atomic scale, scanning tunneling microscopy, transformation of energy in biological cells, selective electrodes for the determination of ions, and new kinds of electrochemical cells, batteries and fuel cells.The present subvolume contains the related relevant data together with a precise description of the phenomena.

Volume III/27 covers the magnetic properties of non-metallic inorganic compounds based on transition elements. The present subvolume III/27j2 covers the halides composed out of three types of elements, A, M, and X, where generally A represents an alkali element, M a 3d element and X a halogen element.

Polymers belong to an essential material group with many applications not only for polymer manufacturers but also in physics, chemistry, medicine and engineering techniques.

Vapor-liquid equilibrium data, heat of mixing (excess enthalpies), and volumetric properties of systems are required for both the applications in design of industrial technological processes and the understanding the structure and the intermolecular interactions in the systems.

The Landolt-Boernstein volume II/30 contains data on the geometric parameters (internuclear distances, bond angles, dihedral angles of internal rotation, etc.) of free polyatomic molecules including free radicals and molecular ions.

The magnetic properties of silicates and phosphates are compiled in subvolume 27I. While subvolumes 27I1, 27I2, 27I3, 27I4, 27I5 and 27I6 (already published) deal with orthosilicates, sorosilicates, cyclosilicates, inosilicates, and phyllosilicates, respectively, the present subvolume 27I7 deals with phosphates.

The volume 'Medical Radiological Physics' is intended to provide the scientific basis of diagnostics and therapy in medical radiology.
