Since the photoalignment treatment is scratch-free, the thickness of the photoaligned film can be reduced below 4 nm without decreasing its alignment ability for PFO. Even though polyimide is a good insulator, such a very thin photoaligned film can be inserted into PLED structures.
We examined the influence of the thickness of the photoaligned polyimide film and the light-emitting layer on the polarization ratio and Metabolism inhibitor the current efficiency of the polarized PLEDs. Using a 2.9 nm-thick polyimide photoalignment layer and a 101 nm-thick PFO light-emitting layer, we have succeeded in fabricating a polarized PLED with a current efficiency of 0.3 cd/A at 150 cd/m(2) and polarization ratios of 46 at 434 nm, 27 at 460 nm, and 20 for integrated intensity from 400
to 600 nm. (C) 2010 American Institute of Physics. [doi: 10.1063/1.3445774]“
“Copper phthalocyanine blue was encapsulated with a copolymer of styrene and maleic acid (PSMA) via a phase-separation technique, and a PSMA-encapsulated pigment dispersion was prepared. The effects of the additive on the stability of the dispersion were studied. Scanning electron microscopy photographs revealed that the particles in the PSMA-encapsulated pigment dispersion were more uniform than EGFR activity those in a PSMA-dispersed pigment dispersion. X-ray photoelectron spectroscopy provided evidence that the PSMA-encapsulated pigment acquired abundant carboxylic groups that could improve its wettability to water. Moreover, the results also indicated that the PSMA-encapsulated pigment dispersion had improved color strength, its stability could be greatly influenced by the pH value and ion strength,
and its apparent viscosity changed little with an increase in the shear rate. (C) 2010 Wiley Periodicals, Inc. J Appl Polym Sci 117: 211-215, 2010″
“Background: Lung cancer BEZ235 cost is the leading cause of cancer deaths in the United States. In recent years, significant advancements have been made in the molecular characterization of tumors, and the availability of new agents to treat non-small-cell lung cancer has increased. Despite these achievements, optimal care of patients with this condition remains less than ideal. Although national quality measures and guideline recommendations provide the necessary framework for patient care, routine self-assessment of adherence to these measures is required for physician practice improvement. To this end, a performance improvement initiative that met national continuing medical education standards was designed.
Methods: Focusing on non-small-cell lung cancer patient care, oncologists underwent a three-step process that included a self-assessment of predetermined performance measures, the development and implementation of an actionable plan for improvement, and a second round of assessment to measure practice change.
Results: A total of 410 unique patient charts were reviewed by 22 practicing oncologists.
