Polymers belong to an essential material group with many applications not only for polymer manufacturers but also in physics, chemistry, medicine and engineering techniques. This volume gives an introduction to the thermal properties and PVT-data of polymer solids and polymer melts.

With the development of modern instruments and theories, a considerable amount of spectroscopic information is being permanently collected on molecules. It is made up of several volumes (A, B, C, D) with comprehensive compilation of critically evaluated molecular constants of diatomic (A), linear triatomic (B);

Zeolites and zeolite-like materials became important because of their ion exchange capacities and their outstanding catalytic properties. It is designed as a reference work for zeolite chemists and materials scientists, but it also serves as a tool to interpret structural similarities and to derive new structures from known topologies.

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

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 sub volumes A of volume VIII/6 form a series of data collections and handbooks covering properties of polymer solids and polymer melts.

The Landolt-Boernstein subvolume III-44G is the seventh part of an update to the existing eight volumes III-41 about Semiconductors and contains New Data and Updates for IIa-VI Compounds (Structural Properties, Thermal and Thermodynamic Properties, and Lattice Properties).

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. Subvolume II/30A covers inorganic molecules and molecules containing one or two carbon atoms.

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 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.

Volume 43 of Group III deals with crystallographic data of both intermetallic and classical inorganic compounds, thus forming an update of the former Landolt-Boernstein volumes III/6 (Structure Data of Elements and Intermetallic Phases) and III/7 (Crystal Structure Data of Inorganic Compounds).

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

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

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.

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.

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.

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.

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 ...
