    Description: The coagulation protease thrombin triggers fibrin formation, platelet activation, and other cellular responses at sites of tissue injury. We report a role for PAR1, a protease-activated G protein-coupled receptor for thrombin, in embryonic development. Approximately half of Par1-/- mouse embryos died at midgestation with bleeding from multiple sites. PAR1 is expressed in endothelial cells, and a PAR1 transgene driven by an endothelial-specific promoter prevented death of Par1-/- embryos. Our results suggest that the coagulation cascade and PAR1 modulate endothelial cell function in developing blood vessels and that thrombin's actions on endothelial cells-rather than on platelets, mesenchymal cells, or fibrinogen-contribute to vascular development and hemostasis in the mouse embryo.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Griffin, C T -- Srinivasan, Y -- Zheng, Y W -- Huang, W -- Coughlin, S R -- HL44907/HL/NHLBI NIH HHS/ -- HL65590/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 2001 Aug 31;293(5535):1666-70.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Cardiovascular Research Institute, University of California at San Francisco (UCSF), San Francisco, California 94143.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11533492" target="_blank"〉PubMed〈/a〉

    Description: We demonstrate the fabrication of polymer solar cells in which both a PEDOT:PSS hole transport and a PCDTBT:PC 71 BM photoactive layer are deposited by spray-casting. Two device geometries are explored, with devices having a pixel area of 165 mm 2 attaining a power conversion efficiency of 3.7%. Surface metrology indicates that the PEDOT:PSS and PCDTBT:PC 71 BM layers have a roughness of 2.57 nm and 1.18 nm over an area of 100 μ m 2 . Light beam induced current mapping reveals fluctuations in current generation efficiency over length-scales of ∼2 mm, with the average photocurrent being 75% of its maximum value.
