Volume IV/7 -Liquid Crystals- is devoted to critically selected and assessed fundamental data, mainly transition temperatures, which characterize the existing liquid crystalline phases and states of a large number of compounds. Due to the technical importance of liquid crystalline materials and its unique properties an intensive interdisciplinary research has been performed during the last decades. As a result a fast growing number of liquid crystalline compounds - from 14.000 in 1982 to about 50.000 in 1992 - were detected and the corresponding physical, chemical and biochemical...

Volume 32 of Group III is a supplement to volume III/19 and deals with the magnetic properties of metals, alloys and metallic compounds which contain at least one transition element.
The present subvolume III/32C provides comprehensive and evaluated data on magnetic properties of alloys and compounds of d-elements with main group elements published mainly in the previous decade.

This index is a guide to organic compounds which have material constants of general interest described in the Landolt Bornstein New Series. Compiled are volumes containing molecular constants, density, surface tension, dielectric constants, refractive index, vapor pressure, phase transition temperatures and transition enthalpies. In total, 16,897 compounds with 33,828 references to numerical data are recorded. All compounds are given with the drawing of the chemical structure, the molecular formula, chemical names, the Chemical Abstracts Registration numbers (CAS-RN) and references to all the...

Zeolites and zeolite-like materials became important because of their ion exchange capacities and their outstanding catalytic properties. Millions of tons of zeolites have been produced for the oil refining industry alone and, in even greater quantities, as ion-exchanging softening agents for detergents. Numerous other applications, e.g. in environmental protection, farming, gas separation, medicine, and pharmacy, are known, making zeolites almost a necessity of daily life. Consequently, there are many, research activities dealing with zeolites properties and characterization. This is a...
