Results of measurements in situ of electrostrictive strain, dielectric polarization, dielectric constant, and crystallographic parameters as functions of applied electric field in the temperature range 20–200 °C of Pb0.97La0.02(Zr0.66Ti0.11Sn0.23)O3 composition are reported. The antiferroelectric to ferroelectric phas…
Abstract The large contents of octahedral vacancies in published formulae of chlorite from hydrothermal systems and clastic sequences are shown to be largely caused by inclusion of other minerals. Verification is provided by analytical electron microscope (AEM) analyses of chlorite in pelitic rocks from the Gaspé Peni…
The Commission on Powder Diffraction of the IUCr has undertaken a round robin of Rietveld refinement with the aims of: (i) evaluating a cross section of currently used software; (ii) examining the range and effect of various strategies of refinement; (iii) assessing the precision and accuracy (spread) of the derived p…
Stable radical species (e.g. see Fig.) can form an alternative source of organic conducting materials. Suppressing the Peierls distortion and stabilizing the metallic state can be achieved by applying pressure or by developing materials with enhanced two and three‐dimensional interactions. Recent progress in the synth…

A three-dimensional covalent network of N atoms possessing a fraction (${\mathit{n}}_{\mathit{r}}$/N) of r-fold-coordinated atoms will, in general, display percolation of rigidity at an average coordination number 〈r〉=2.4-0.4(${\mathit{n}}_{1}$/N), where ${\mathit{n}}_{1}$/N represents the fraction of onefold-coordina…
Abstract A new, well-ordered, thermally robust ethylene glycol intercalate of kaolinite was formed by refluxing the dimethyl sulfoxide intercalate of kaolinite (Kao-DMSO) with dry ethylene glycol (EG). This new phase (Kao-EG 9.4 Å) which is characterized by a d 001 of 9.4 Å is distinct from a previously reported ethyl…

This unit describes the procedure for subcloning the sequence encoding the protein of interest into an maltose-binding protein (MBP) vector, and expressing and purifying the fusion protein from the cytoplasm. MBP vectors include a sequence that encodes the four-amino-acid recognition site for the specific protease fac…
In analogy with the well-known theory for fluids a van der Waals theory for solids is proposed. It is shown that, in agreement with recent predictions, the competition between the van der Waals loop of the fluid and the van der Waals loop of the solid can produce three different types of phase diagrams for a simple fl…
