The traditional favour enjoyed by cement including additions and by their diverse uses in Chile calls for an extense investigation of their behaviour in order that the results may justify their utilization in specific projects. This works studies volume changes occurring in cement pastes and mortars containing pozzola…
An attempt is made to summarize both theoretical and experimental aspects of generalized atomic displacement parameters (ADP's) in crystalline matter. Generalized displacement parameters are used to describe the weakening of Bragg intensities via the anharmonic (static or thermal) Debye–Waller factor (DWF) and its rea…

Experimental observations of the tetragonal phase transformation behavior in polycrystalline zirconias and the related toughening contribution are presented. An analysis which considers transformation thermodynamics and residual stresses is developed to describe the influence of grain size on tetragonal‐to‐monoclinic…
The shape, the typical orientation, and the average size of mineral crystals in different types of mineralized tissues were investigated by means of small-angle x-ray scattering (SAXS). To rule out eventual artifacts due to sample preparation, four different standard preparation techniques were used and a comparison s…

The characteristic features of alpha - and beta - relaxation in the supercooled state of nonnetwork forming liquids and polymers are reviewed. Particular emphasis is put on properties observed recently by neutron scattering and molecular dynamics studies within the mesoscopic time region. The data indicate the existen…
A review is given of theoretical and experimental papers on the interaction of acoustic waves with spin waves in ferridielectrics. The region of the resonance interaction—the magnetoacoustic resonance (MAR), in which the interaction is synchronous and is most effective, is discussed in greatest detail. Considerable at…
The methods of preparation of deposited palladium catalysts on carbon carriers are discussed. The characteristics of the structures of porous carbon materials, the methods for the regulation of their structural and physicochemical characteristics, the methods for the deposition of palladium on a carbon carrier, and in…
An analysis is made of the shape of the phase diagrams of substances in the neighborhood of the Lifshitz point, which separates the second-order phase transitions going from the initial phase to a commensurate and to an incommensurate phase. The conclusions of the thermodynamic theory in the mean field approximation a…
Polymers constitute one of the four main areas of materials science. Modern research in polymers focuses on the ways in which tailored macromolecules organize themselves in the solid state and on materials design and synthesis at the interface between polymer science and the fields of ceramics, metals, and electroacti…
A review of advances for aircraft engine structural materials and processes is presented. Improved materials, such as superalloys, and the processes for making turbine disks and blades have had a major impact on the capability of modern gas turbine engines. New structural materials, notably composites and intermetalli…
Many organisms construct structural ceramic (biomineral) composites from seemingly mundane materials; cell-mediated processes control both the nucleation and growth of mineral and the development of composite microarchitecture. Living systems fabricate biocomposites by: (i) confining biomineralization within specific…
Abstract In the last decade crystallography has emerged as a key tool for understanding the structures of biological macromolecules, yet the crystallization techniques themselves have been perceived as difficult to perform. This book provides the first detailed and rational guide to producing crystals of proteins and…
