Abstract

The high-resolution neutron powder diffraction data of the lead hafnate titanate pb(Hf(sub x)Ti(sub 1)-(sub x))O(sub 3) powder with 0.10 (less than equal to) X (less than equal to ) 0.50 are analyzed using Rietveld refinement. It is observed that the structural features of transition sequences and lattice parameters are similar to the lead zinconate titanate (PZT) ceramics

The aim of this study was to clarify the clinical role of CSC-related markers in patients with lung adenocarcinoma and to determine whether each CSC-related marker expression correlates with the histologic subtyping proposed by the International Association for the Study of Lung Cancer (IASLC), the American Thoracic Society (ATS), and the European Respiratory Society (ERS) classifications.Methods: We reviewed data for all 103 patients in whom complete resection of adenocarcinoma had been performed. Expression of CSC-related markers, ie, aldehyde dehydrogenase 1A1 (ALDH1A1), aldo-keto reductase 1C family member 1 (AK1C1), and 1C family member 3 (AK1C3), was examined using immunostaining on whole-mount tissue slides, and the tumors were reclassified according to the IASLC/ATS/ERS classification.Results: ALDH1A1 expression was observed in 66.0% of tumors, AK1C1 in 62.7%, and AK1C3 in 86.1%. Immunoreactivities with the frequency of mean expression of ALDH1A1 in papillary predominant adenocarcinoma were significantly higher than those of solid predominant adenocarcinoma (P

44. Chelating of titanium by lactic acid in the water-soluble diammonium tris(2-hydroxypropionato)titanate(IV)

Abstract

The synthesis and structure of a new titanium-lactic acid complex is described which is soluble and stable in water. The results of the (super 13)C NMR spectrum indicate that lactic acid should either chelate titanium in a bidentate manner similar to the bis(ammonium lactato)titanium dihydroxide or bridge two titanium atoms.

Abstract

Raman scattering measurements have been carried out on poly(propylene oxide) complexed with NaCF3SO3 salt of concentration O:M=30:1 (where O:M is the PO:Na ratio) over a temperature range of 186–360 K in order to study ion–ion associations of the dopant salt and their temperature dependence. Splitting of the symmetric stretching mode of the CF3SO-3 anion into a double band was observed and attributed to the existence of different environments of the anions. A two-component band analysis led to the identification of coexisting dissociated free ions and ion pairs, suggested to be in contact. Below the glass transition temperature, Tg, the intensity of the mode corresponding to the free ions was more or less constant with temperature; the amount of free ions in the glassy state was found to be about 84% of the total salt concentration. Above Tg the amount of dissociated free ions decreased rapidly with temperature in an Arrhenius-type behavior. The resulting reduction of the number of charge carriers has little influence on the conductivity, which is reported to dramatically increase with increasing temperature. It is concluded that the major factor determining the temperature dependence of the conductivity is the mobility rather than the number of charge carriers. [ABSTRACT FROM AUTHOR]
