New water-soluble styrenic polymers bearing two functional groups, pendant ammonium salts of half-esters of malonic acids and acid-labile alkyl esters, were synthesized and evaluated for water-soluble positive-tone photoresist application. These polymers feature two solubility switches: insolubilization of the entire film by baking and selective solubilization upon exposure to UV light. Time-resolved FT-IR measurement of the baked films showed sequential evaporation of ammonia from the films and ...

CA 19-9 is a marker of malignancy of the pancreas and biliary tract. We report the case of a patient who had significantly elevated serum CA 19-9 levels and imaging studies suggestive of malignancy. On laparotomy, the patient was found to have Mirizzi syndrome, an uncommon cause of biliary obstruction from an impacted gallstone. This case illustrates that elevated serum CA 19-9 levels must be interpreted cautiously in cases of biliary obstruction.

Stoichiometric Ba1−xSrxTiO3 (BST; x=0.4) thin films were prepared by the polymeric precursor method. High quality polycrystalline films of BST with low roughness (≈3 nm) were obtained from a Pt/Ti/SiO2/Si substrate deposited by spin-coating technique. Microstructure and morphological evaluation were done using grazing incident X-ray diffraction (GIXRD), scanning electron microscopy (SEM), and atomic force microscopy (AFM). Grazing incident angle XRD characterization of these films showed that BST phase ...

Intense photoluminescence in highly disordered (amorphous) BaTiO3, PbTiO3, and SrTiO3 prepared by the polymeric precursor method was observed at room temperature. The emission band maxima from the three materials are in the visible region and depend on the exciting wavelength. The origin of the photoluminescence was not exactly identified. However, the line shape indicates that confinement effects are not probable. The experimental results indicate that it could be related to the disordered perovskite ...

The effects of doping of ZrO with pentavalent ions have been insufficiently studied, given that some results indicate that doping does not suppress the monoclinic-tetragonal transformation of the material. To assess the influence of Nb and the calcination conditions on the morphology of ZrO2 in this study, ZrO2:Nb was prepared with dopant concentrations of 2.5 mol%, 5.0 mol% and 7.5 mol%, and was microwave and conventionally calcined at temperatures of 500–1000 °C. The XRD results revealed the presence ...

Pentavalent metals have been used as donors in tin dioxide, giving it varistor characteristics when associated with densifiers such as CoO or MnO2. However, attempts to obtain varistor behavior in SnO2-based ternary systems using hexavalent donors such as W6+ have been unsuccessful to date, leading to typical linear behavior. Here it is shown that one can achieve nonlinear behavior in this kind of system, given a suitable choice of densifier (MnO2). In order to get insights into the role of WO3 content ...
