“Overdamped NbTiN Josephson junctions CHIR-99021 cell line with Ti-TiN bilayered normal-metal barrier are proposed for metrological applications. Binary arrays consisting of 32 768 NbTiN/Ti-TiN/NbTiN junctions were fabricated

for quantum voltage standards, and a Shapiro step at 1 V with the step height of about 0.5 mA was generated at around 8 K. The Ti layer was added to protect the base NbTiN electrode from nitrogen plasma during the deposition of the TiN layer. While the critical current I(c) and the junction resistance R(n) are mainly dominated by the thickness of the TiN barrier, I(c) can be also adjusted by changing the thickness of the Ti barrier to maximize the

operating margin for voltage standard circuits. An optimization of the NbTiN film in terms of film stress is also described for fabrication of circuits containing such a large number of junctions. (c) 2010 American Institute of Physics. [doi: 10.1063/1.3517475]“
“Polymer-filled nonwoven membranes were prepared by filling the open pores of nylon nonwovens with poly(2-acrylamido-2-methyl-1-propanesulfonic acid) (PAMPS). PAMPS was synthesized via radical polymerization and crosslinked to prevent its dissolution in water. PAMPS-filled nylon nonwoven membranes showed enhanced dimensional stability and mechanical properties when compared with PAMPS membranes without nonwovens. The conductivities of PAMPS-filled nylon nonwovens were slightly lower selleck than those of PAMPS membranes. Compared with PAMPS membranes without

nonwoven hosts, both linear and crosslinked PAMPS-filled nylon nonwoven membranes exhibited lower vapor permeabilities for water, methanol, acetone, and dimethyl methylphophonate (DMMP). In addition, crosslinked PAMPS-filled nonwoven membranes presented high permselectivity on DMMP over water, which is critical for chemical protection application. (C) 2010 Wiley Periodicals, Inc.

“Metaplastic Warthin tumor is a rarely seen subtype of Warthin tumor. Selleckchem STI571 It can resemble squamous carcinomas histopathologically, because it contains atypical squamous cells on the necrotic surface. Making a diagnosis can become easier by knowing this entity of Warthin tumor well and by correlating the radiologic findings with pathology. In this case presentation, imaging features of a metaplastic Warthin tumor are presented together with its histopathologic findings. When a solid mass with peripheral enhancing cystic-necrotic component and well defined contour and capsule that shows early enhancement and washout is identified with imaging methods in parotid gland, metaplastic Warthin tumor should be indicated in the differential diagnosis before the histopathologic evaluation.
