This work, devoted to the First Consultation sponsored by ONUDI-UNCHS (HABITAT) relative to "Building Materials Industry", selects three different sides of it: the final version of the conclusions and recommendations prepared in Athens by the participants, the author personal answers, as a participant himself, to some…
Abstract Chemical analysis (including H 2 , F 2 , FeO, Fe 2 O 3 ) of a Mg‐vesuvianite from Georgetown, Calif., USA, yields a formula, Ca 18.92 Mg 1.88 Fe 3+ 0.40 Al 10.97 Si 17.81‐ O 69.0.1 (OH) 8.84 F 0.14 , in good agreement on a cation basis with the analysis reported by Pabst (1936). X‐ray and electron diffraction…
Abstract An electrically conductive plastic material was obtained by the electrochemical polymerization of pyrrole in a poly(vinyl chloride) matrix. The transmission electron microscopy shows that polypyrrole is uniformly distributed in the matrix. The conductivity of the composites fall in the range of 5 to 50 S/cm,…

Structural models previously proposed for metakaolinite are examined in light of the most recent published experimental data and new information obtained by solid‐state high resolution 29 Si and 27 AI NMR. A new model for metakaolinite is proposed, consisting of anhydrous regions of distorted AI‐0 tetrahedra containin…
The results of experimental studies of the crystal and domain structures of NaO, 5BiO, 5TiO3 as well as its lattice dynamics, dielectric, optical and other physical properties are considered. Nature of peculiar temperature points is discussed.
Abstract New measurements are presented for film height and pressure drop for vertical gas‐liquid annular flows. Improved methods for predicting the film height and interfacial friction factor are developed for situations in which the liquid film flow rate is known.

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…
