The derivation of the generating function given by Bleris & Delavignette [Acta Cryst. (1981), A37, 779- 786] is simplified and made rigorous. It is shown that their main result can also be deduced directly from Grimmer [Acta Cryst. (1974), A30, 685-688]. The following applications of the generating function are descri…
The attack of fluoride on passive nickel has been studied in strongly acidic solutions and weakly acidic and alkaline buffers. Two main potential ranges with different kinetics of metal dissolution were found. In the whole passive range, the corrosion current density is increased. Up to 1.1V, the transfer of the Ni 2+…
Abstract Copolymers of 1,1‐difluoroethene with tetrafluoroethene, chlorotrifluoroethene, and bromotrifluoroethene have been prepared by emulsion polymerization, and their crystallinity has been investigated by means of x‐ray diffraction. The results are discussed in relation to copolymer composition and structure.
Abstract Fundamental kinetic equations for nonisothermal crystal growth from preexisting nuclei are derived, by introducing a concept of reduced time. A method of kinetic analysis of thermoanalytical data of these processes is proposed, and all kinetic parameters can be estimated by the method, so that the process pro…
The model of Uehara and Gillman was used to estimate the amounts of permanent surface charge, and variable surface charge at soil pH, in two soils from the high rainfall region of coastal Queensland. For each soil series, samples from virgin rain-forest were compared with soil collected from nearby sugarcane fields. O…
Abstract Michael additions of the secondary diamines N , N ′‐dimethyl‐1,6‐hexanediamine ( 14 ) or piperazine to the electrophilic carbon–carbon double bonds of N , N ′‐bismaleimido‐4,4′‐diphenylmethane ( 2 ) or N , N ′‐bismaleimido‐1,8‐octane ( 4 ) afford four unusual, high‐molecular‐weight (η inh = 0.49–2.16 dL/g) po…

Three-dimensional structures of charge-density waves in 1T-Ta dichalcogenides are studied on the basis of a phenomenological free energy, in which interlayer couplings up to the second neighbor layer are considered. Special attention is paid to the commensurate (C) and striped discommensurate (DC) states. Several stab…

Multi‐element soil extraction solutions offer increased convenience in soil testing laboratory operations. The recently developed Mehlich III and ammonium bicarbonate‐DTPA multi‐element extraction solutions were each compared with the more conventional Bray/Kurtz extractant for P determination and with 1N ammonium ace…
Abstract An experimental study of the system CaCO 3 –MgCO 3 –FeCO 3 was undertaken in order to calibrate the iron correction to the calcite–dolomite geothermometer, which is based on the solubility of magnesium in calcite in the assemblage calcite + dolomite. The experiments, at 450°C and lower temperatures, resulted…
Absorption spectra have been measured on polythiophene films subjected to electrochemical Bu 4 N + doping. The spectra show essentially the same evolution as those for BF - 4 doping, i.e., peaks at 0.6∼0.7 eV and 1.5∼1.8 eV appear upon doping in addition to the band-to-band absorption peak at 2.6 eV. Propagation veloc…
Needle-shaped thermoseeds have been manufactured from an alloy consisting of 70.4% nickel and 29.6% copper. The magnetic properties of the alloy were measured at various temperatures and from this the heating power produced by a thermoseed exposed to an electromagnetic induction field was computed as a function of the…
Abstract Palladium compounds such as Pd(PPh3)4 and Pd(OAc)2 catalyze polycondensation between dihalo aromatic compounds, X–Ar–X (Ar=p-phenylene, 2,5-thiophenediyl, 9,10-anthracenediyl, 2,6-pyridinediyl, p-benzenedicarbonyl, p-xylene-α,α′-diyl), and acetylenic compounds (p-C6H4(C≡CH)2 or p-C6H4(C≡CMgBr)2). The polymers…

Abstract With the accelerator MDB and with MBTS-sulfur, the addition of a relatively small amount of the zinc-accelerator complex (1) caused rapid formation of model crosslinks in 2-methyl-2-pentene under conditions in which neither model crosslink precursors nor model crosslinks were formed appreciably in its absence…
