This paper reviews the crystal structure of compounds with the general formula AB2X4,
which crystallize with the same atomic structure as the mineral spinel, MgAl2O4. Three …

Laser nitriding can be described as the irradiation of metal surfaces by short laser pulses in
nitrogen containing atmospheres. This may lead to a strong take-up of nitrogen into the …

Principles of Nucleic Acid Structure, Second Edition, provides the most complete and
concise summary of underlying principles and approaches to studying nucleic acid structure …

Phase diagrams are used in materials research and engineering to understand the
interrelationship between composition, microstructure and process conditions. In complex …

抄録 It is convenient to grasp crystals of a kind as “ferroelastic” crystals. They are defined
analogously to “ferroelectric” crystals, mechanical strain and stress in the former …

Introduction. Groups of transformations which leave invariant a specified item are familiar
objects of study for students and researchers alike. Finite groups of plane isometries which …

Taking and analyzing images of materials' microstructures is essential for quality control,
choice and design of all kind of products. Today, the standard method still is to analyze 2D …

This book gives a rather exhaustive list of isotropy subgroups of the 230 crystallographic
space groups. The symmetry changes for the vast majority of observed phase transitions in …

With the recent growth in interest in the ir and Raman spectra of crystals, it has become very
important to know which vibrational modes are optically active. Hornig, Winston and Halford …

The new sixth edition of Modern Algebra has two main goals: to introduce the most important
kinds of algebraic structures, and to help students improve their ability to understand and …
