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…

The excretory behavior of nine nephrotropic contrast agents with varying physicochemical properties such as charge, lipophilicity, and molecular size was investigated. Renal clearance in comparison with inulin was determined by means of the continuous infusion method. Each contrast agent was infused at three dose leve…

Problems which arise in the application of closed-shell coupled-cluster approaches to quasidegenerate or almost degenerate situations are discussed and the basic classification of quasidegeneracy types is outlined. Recent coupled-cluster results obtained for the cyclic polyene model, particularly in the strongly corre…

Coherent anti-Stokes Raman scattering signals may be strongly enhanced when the active molecules are located near the surface of a small silver particle. The theoretical analysis is similar to the electrodynamic mechanism for surface-enhanced Raman scattering, except that there are four instead of two electric fields…
The preparation and characterization of Hong and von Alpen types of Nasicons are described. When highly reactive gel‐processed powders are heated at about 1000°C, Nasicons are formed in a finely divided state. Sintering of compacts requires 1125° to 1325°C, depending on the composition. Observed sintering kinetics sug…
