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

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.

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

The use of units for physical quantities in the present volume follows largely the rules given by the International Astronomical Union (IAU), c.f. However, the centimetre-gram-second (CGS) system is used in some sections of the present volume, since it is still dominating in certain areas of astrophysics.

Focuses on data for ternary systems for one vitally important specific class of materials, steels. This title presents various diagrams for each system, calculated from a specially developed SGTE database for steels.

This volume 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.

Data on ferroelectric and antiferroelectric behaviour of pure compounds and solid solutions are critically evaluated and in addition all other properties relevant to the characterization of these crystals are presented in tables and figures.

This series of Landolt-Boernstein volumes is summarizing our current knowledge of the phenomena of mesoscopic quantum systems with spatial extensions between those of atoms and ordinary macroscopic solids. At low temperatures, they are said to become "quantum mechanically coherent" with states that extend over the whole system.

Volume 12 of group IV presents phase diagrams, crystallographic and thermodynamic data of binary alloy systems. The subvolume B contains systems from B-Ba to C-Zr. Volume 12 forms a supplement to volume 5.

The magnetic and related properties of lanthanide and actinide pnictides and chalcogenides have been compiled in subvolume 27B.

The magnetic properties of lanthanide and actinide pnictides and chalcogenides have been compiled in subvolume 27B.

The thermodynamic properties of fluids are vital information for design, operation (including safety considerations) and maintenance in the fluid processing or continuous manufacturing industries.

Nuclear Magnetic Resonance (NMR) is based on the fact that certain nuclei exhibit a magnetic moment, orient by a magnetic field, and absorb characteristic frequencies in the radiofrequency part of the spectrum.

The porphyrins are an important class of naturally occurring macrocyclic compounds that play a very important role in the metabolism of living organisms.

The subject of this Landolt-Boernstein volume is to present data on the magnetic properties of materials under pressure. This comprehensive set of data shows crystallographic data (space group, lattice constants) and magnetic properties such as magnetic moment, magnetic transition temperature, magnetization, magnetic structure, and others.
