In the blue light-emitting polymer poly(9,9-dioctylfluorene) (PFO) two distinct morphological phases have been identified, that is the glassy phase and a planar β-phase. We show that the proportion of the formation of the two phases can be controlled by simply spinning thin films from different solvents such as chloroform and cyclopentanone. We use a Franck-Condon analysis with vibrational modes obtained...
To determine if the density of diode laser photocoagulation for the treatment of zone 1 or zone 2 threshold retinopathy of prematurity (ROP) affects the rate of progression of the disease.Retrospective, nonrandomized, comparative trial (n = 12) and prospective, randomized, clinical trial (n = 46).Two surgeons treated a total of 107 eyes from 58 patients with zone 1 or zone 2 threshold ROP within 72...
