Phase changes and the microstructure resulting from low‐temperature annealing of yttria‐doped tetragonal ZrO 2 polycrystals in water were investigated at 65° to 120°C. Tetragonal ZrO 2 on the surface of the sintered body transformed to the monoclinic phase, accompanied by microcracking. The transformation rate in wate…
The newly developed simulation method known as Stokesian dynamics is used to investigate the rheological behaviour of concentrated suspensions. Both the detailed microstructure (e.g. pair-distribution function) and the macroscopic properties are determined for a suspension of identical rigid spherical particles in a s…

Acidic matrix macromolecules are intimately involved in biological crystal growth. In vitro experiments, in which crystals of calcium dicarboxylate salts were grown in the presence of aspartic acid-rich proteins, revealed a stereochemical property common to all the interacting faces. Calcite crystals are nucleated on…
An MCSCF procedure is described which is based on the direct minimization of an approximate energy expression which is periodic and correct to second order in the changes in the orthonormal orbitals. Within this approximation, the CI coefficients are fully optimized, thereby accounting for the coupling between orbital…
Abstract The establishment of charge density waves (c.d.ws) in NbSe3 and the phenomena associated with their sliding are examined against the background of behaviour presented for a variety of other stranded transition metal chalcogenides. The work has been set in terms ofdiscom mensuration arrays, but with these not…
Abstract The results of a series of experiments demonstrate that solitons are the important excitations in trans-(CH)x and that the properties of these nonlinear excitations can be directly studied during photoexcitation or after doping. The importance of these concepts in the more general context of conducting polyme…
Abstract In contrast with intercalation compounds, which can exist both with and without organic molecules between the planes of inorganic material, ‘molecular composite’ compounds have organic groups covalently or ionically bound to inorganic layers. In such crystals the aim is to combine magnetic or optical properti…
Abstract Raman spectra of CxF1-δ(HF)δ(x/δ ≈ 12) show bands at 1600, 1355 and 839 cm-1, which are attributed to graphite-like vibrational modes of the carbon atom sheets. The infrared spectra show, in addition to graphite-like bands, absorptions at 1270 and 1100 cm-1, which are attributed to C-F stretching. Variable co…
Abstract The conductivity of certain organic polymers can be raised to metallic levels by chemical or electrochemical ߢp-doping’ (oxidation), or ‘n-doping’ (reduction). Polyacetylene, (CH)x, the prototype conducting polymer, has been studied more extensively than any other conducting polymer and the doping concepts in…
A new model of liquid-solid freezing, based on the orientational order in a three-dimensional liquid, is proposed. The novel aspect of the model is the inclusion of the coupling between the orientational and elastic degrees of freedom in a dense liquid. This allows for the explicit computation of several thermodynamic…
The application of the phenomenon of thermoluminescence to the measurement of absorbed radiation dose has progressed a great deal since the initial work by Daniels and colleagues referred to in chapter 1. Several thermoluminescent phosphors are now used routinely in many dosimetric applications. This chapter deals wit…
In order to explain ferrielectric behaviour, a phenomenological model given in terms of the polarisations of two non-equivalent sublattices is proposed. The free energy for a second-order phase transition is G= 1 / 2 f 1 P 1 2 + 1 / 2 f 2 P 2 2 +gP 1 P 2 + 1 / 4h(P 1 4 +P 2 4 ) (G>0, h>0), where f 1 -(T-T 1 )/C 1 and…
Molecular dynamics simulations of supercooled and glassy states of binary 'soft sphere' mixtures are reported. The transition to the amorphous solid phase appears to be smooth and takes place at a roughly concentration-independent value of an effective coupling parameter derived from a simple 'one-fluid' model.
In the h.c.p. structure three kinds of basal stacking faults can occur: two intrinsic faults (I1 and I2) and one extrinsic fault (E). In this study all three of them are observed and analysed by electron microscopy methods in pure Co. Special care is needed to distinguish I1 and I2 faults since several violations of t…
Aggregate centers in reactor irradiated single crystal α-Al2O3 are investigated using the thermochemical and photochemical methods. Isochronal and isothermal annealings of the bands at 302, 356, 450, and 570 nm are performed in detail to study the thermal stability and to obtain the activation energy (E) for the decay…
