“Recently a simple recipe has been developed to prepare
Ag nanoparticles in a TiO2 matrix Okumu , [J. Appl. Phys. 97, 094305 (2005)] and Dahmen , [Appl. Phys. Lett. 88, 011923 (2006)]. In this scheme, silver nanoparticles are formed in a TiO2 matrix by sputtering a thin silver film sandwiched between TiO2 layers, followed by an annealing process. To determine the formation mechanism of noble metal nanoparticles in the TiO2 matrix, we compare the behavior of Ag with two similar noble metals, gold and copper. The formation of metal nanoparticles in the TiO2 matrix is investigated using a combination of techniques including x-ray diffraction, x-ray reflectance, and optical spectroscopy. Despite the similarity of the three noble metals, no nanoparticles are formed from Cu and Au. This is in striking contrast to the behavior observed for Ag. The difference Geneticin nmr can be explained by a three step process, which involves oxidation of the metal, dissociation of the metal check details oxide upon annealing, and metal aggregation to form nanoparticles.

“Objectives: To determine whether caveolin-1 expression is associated with bladder pain syndrome/interstitial cystitis (BPS/IC) and
to better understand the pathogenesis of BPS/IC. Methods: The study population was composed of 19 women with BPS/IC and 7 healthy women as controls. Midstream urine specimens were collected before cystoscopy and cold cup bladder biopsies were obtained from the trigone of the bladder. Caveolin-1 protein expression was determined by indirect immunofluorescence and Western blot analysis in cases and controls, using a rabbit polyclonal antibody against caveolin-1. chi(2) test and Student’s t test were used in the statistical analysis. Results: A statistical difference of caveolin-1 protein expression was observed between BPS/IC and healthy controls (p < 0.05, chi(2) test). Western blot analysis showed that the GS-1101 research buy mean relative integrated density value of caveolin-1
in (BPS/IC) patients was significantly higher than that in the control group (p < 0.001, Student’s t test). Conclusions: The results of our study demonstrate that there is a relationship between the raised levels of caveolin-1 expression and BPS/IC. This preliminary study may provide a basis for further investigation of the role of caveolin-1 in the pathogenesis of BPS/IC. Copyright (C) 2011 S. Karger AG, Basel”
“A nonvacuum and low temperature process for passivating transparent metal oxides based thin-film transistors is presented. This process uses the epoxy-based SU-8 resist which prevents device degradation against environmental conditions, vacuum or sputtering surface damage. The incorporation of SU-8 as a passivation layer is based on the ability of this polymer to provide features with high mechanical and chemical stability.
