  Temperature- and Pressure-Induced Charge-Density-Wave to Mott–Hubbard Phase Transitions in Quasi-One-Dimensional Bromine-Bridged Pd Compounds

  摘要：

  Temperature-and pressure-induced transitions from the charge-density-wave (CDW) phase to the Mott-Hubbard (MH) phase in the quasi-one-dimensional Br-bridged Pd compound, [Pd(en)(2)Br](C-n-Y)(2)center dot H2O (n = 4-9, and 12) (en: ethylenediamine, C-n-Y: dialkyl-sulfosuccinate), were investigated by means of crystal-structure analyses and Raman spectroscopy. From the systematic evaluations of the bridging-bromine displacements delta reflecting the CDW amplitudes, the distance L between the neighboring two Pd ions, and the Raman frequency omega(S) of the symmetric Pd-Br stretching mode, we demonstrated that omega(S) is a good measure of the CDW amplitude. By scrutinizing the variations of omega(S) in the pressure-induced and the temperature-induced CDW-to-MH transitions, we discuss the nature of the CDW-to-MH transitions in this category of materials.

  Solubility and Phase Behaviors of AOT Analogue Surfactants in 1,1,1,2-Tetrafluoroethane and Supercritical Carbon Dioxide

  摘要：

  A series of AOT (aerosol-OT) analogue surfactants (sodium salt of dibutyl-2-sulfosuccinate, sodium salt of dipentyl-2- sulfosuccinate, sodium salt of dihexyl-2-sulfosuccinate, and sodium salt of dioctyl-2-sulfosuccinate) were synthesized and characterized by (1)H NMR and elemental analysis. A static method coupled with gravimetric analysis is developed to measure the solubility of the surfactants in 1,1,1,2-tetrafluoroethane (HFC-134a) and supercritical CO(2) (scCO(2)). The solubilities of the surfactants in HFC-134a and scCO(2) are affected by the temperature, pressure, and carbon atom number of the surfactant. The solubility of the same surfactant in HFC-134a solvent is approximately two times that in the most commonly used supercritical solvent CO(2). The pressure-temperature phase diagrams for water/HFC-134a microemulsions stabilized by the surfactants were determined using cloud-point measurements for a concentration range of the surfactant from (1.85 x 10(-3) to 5.60 x 10(-3)) M, temperature up to 338 K, and pressure up to 40 MPa in a high-pressure vessel. At a fixed temperature, the cloud-point pressure increased with increasing water-to-surfactant molar ratio (W(o)). At a fixed Wo, the cloud-point pressure decreased with increasing temperature. The surfactant with the longest hydrocarbon chain has the highest cloud-point pressure even at lower surfactant concentrations.

  Verfahren zur Herstellung eines neuen Pfropfcopolymerisats in Emulsionspolymerisation. Als Pfropfgrundlage wird ein ausschließlich durch anionischen Emulgator (CMC ≧ 0,5 Gew.% in H₂O) stabilisierter sulfonatgruppenhaltiger Vinylester-­Ethylen-Latex verwendet, der ohne weitere Zugabe von Emulgator oder Schutzkolloid vorzugsweise mit Vinylchlorid gepfropft wird. Die erfindungsgemäßen Pfropfcopolymersate zeichnen sich durch gute Wasserfestigkeit und sehr gute thermoplastische Verarbeitbarkeit aus. Sie eignen sich vor allem zur Verwendung als Schlagzähmodifier und zur Erzeugung von weichen bis halbharten Formkörpern.
