Pb(Zr,Ti)O 3 films were deposited by DC magnetron reactive sputtering on Pt/Ti/SiO 2 /Si and Pt/SiO 2 /Si substrates. The activation of oxygen by electron cyclotron resonance (ECR) plasma facilitated the incorporation of Pb. This enabled the fabrication of Pb(Zr,Ti)O 3 films with stoichiometric composition and perovskite structure even at a high Zr/Ti film concentration ratio and high substrate temperature and on Pt/SiO 2 /Si substrates where the pyrochlore second phase was usually observed when the ...

Metal/ferroelectric/insulator/semiconductor (MFIS) capacitors were prepared by depositing PbTiO 3 and TiO 2 layers on Si(100) wafers at 450 and 550°C using metal organic chemical vapor deposition (MOCVD). The C – V properties of the capacitors depend on the quality of TiO 2 films and TiO 2 /Si interfaces. The TiO 2 film could serve as an effective buffer layer against the Pb diffusion and provide good C – V properties as long as it was deposited at proper substrate temperature with proper thickness.

To elucidate the adenoma-carcinoma sequence in the stomach, we investigated Epstein-Barr virus (EBV) incorporation, p53 overexpression, and microsatellite instability (MSI) in gastric adenomas and carcinomas. The study involved 66 cases of gastric carcinomas within or adjacent to adenomas (adenoma-carcinoma cases), 81 cases of simple adenomas (without carcinoma), and 306 de novo carcinomas (without adenoma focus). EBV incorporation was revealed in 1 (1.5%) of the adenoma-carcinomas, in none of the adenomas, ...

BaMgAl10O17:Eu2+ phosphors are synthesized by solid-state calcining of BaCO3, Al2O3, MgO, and Eu2O3 with AlF3 as a flux. The structural and optical properties of the blue phosphor are investigated as a function of the europium concentration in BaMgAl10O17 using the neutron and the X-ray powder diffraction methods and luminescence and X-ray absorption near-edge structure (XANES) spectroscopies. The unit cell parameters of BaMgAl10O17:Eu2+ blue phosphor are calculated through the Rietveld refinements ...

Abstract Integrally skinned PVA membranes have been prepared from PVA/NMP/water system by the phase inversion method in 2‐propanol bath, and the pervaporation characteristics of these membranes were investigated. With an increase in the NMP content in the polymer solution, the formation of skin layer depended on the NMP content in the cosolvent, and the overall morphology of membranes changed from porous to dense structure. Particularly, PVA membranes showed an asymmetric structure composed of a ...

Through the two thermal analysis methods, such as differential scanning calorimeter and thermo-gravimetric analysis, the sintering conditions were defined where the temperature was raised from 150°C to 300°C, all with a fixed sintering time of 30 min. The microstructure and the volume of the printed Ag nanopaste were observed using a field ...

They were divided into two groups; Group A (n = 14) who had undergone a primary gastrectomy for benign gastric disease, and Group B (n = 12) who had undergone the same operation for gastric cancer. EBV infection was present in 29% of Group A, 8% of Group B and 6% of the conventional gastric carcinoma (CGC) (Group A ...

The conservative single-layered wound dressing system is decomposed when mixed in polyvinyl alcohol (PVA) solution, which means it cannot be used with a temperature-sensitive drug. The goal of this investigation was to make an amniotic membrane extract (AME)-loaded double-layered wound dressing with an improved healing result compared to the conservative single-layered wound dressing systems. The double-layered wound dressing was developed with PVA/sodium alginate using a freeze–melting technique; ...

PET is a potentially useful modality for response analysis and prognosis prediction in patients with high-grade non-Hodgkin lymphoma (NHL). The thymidine analog 3′-deoxy-3′- 18 F-fluorothymidine ( 18 F-FLT) was recently introduced as a new tracer. 18 F-FLT uptake correlates with tumor cell proliferation and is suggested to reflect early response to treatment. We performed a prospective study to evaluate the prognostic value of early interim 18 F-FLT PET in patients with NHL. Methods: Patients with ...

The overlap of radiologic findings in many gastric tumors makes differentiation difficult. However, some unusual gastric tumors have characteristic radiologic features that may suggest a specific diagnosis. At barium study, lipomas typically manifest as a smooth submucosal mass or an ulcerated lesion with a "bull's-eye" appearance that is indistinguishable from other mesenchymal tumors. At computed tomography (CT), lipomas usually manifest as well-circumscribed submucosal masses with fat attenuation. ...
