The small molecule 4,7-di-2-thienyl-2,1,3-benzothiadiazole (DBT) dye has been synthesized and blended into blue-emitting polyfluorene as a host. The photophysics of the blend films and electroluminescence device performance was compared with that from polyfluorene-co-4,7-di-2-thienyl-2,1,3-benzothiadiazole (PFO-DBT) copolymer of the same molar composition,(More)
We collected the experimental dataset of a spring-maize in Hetao irrigation district (Bayannaoer, Inner Mongolia) during 2012 and 2013, as well as the crop data observed in related agrometeorological stations to investigate the impacts of light and temperature variation on maize development during the seedling stage to derive adequate light and temperature(More)
Fluorescent nanoparticles have enabled many discoveries regarding how molecular machines function. Quantum dots have been the dominant class of fluorescent nanoparticles but suffer from blinking and from a substantial dark fraction--particles where the fluorescence is never seen--complicating any analysis of biological function. Nanoparticles composed of(More)
Based on the meteorology dataset of 34 stations over the Yinshan area through the recent 30 years (1982-2010), we investigated the key environmental variables influencing potato yield using the correlation and regression methods. Two environmental variables, including the mean temperature difference, precipitation during the growing season, were selected as(More)
