Noncrystalline phases in poly(9,9-di-n-octyl-2,7-fluorene).
Selective formation of amorphous, nematic (N), and beta phases in poly(9,9-di-n-octyl-2,7-fluorene) (PFO) films was achieved via judicious choice of process parameters. Phase structure and film morphology were carefully examined by means of X-ray diffraction as well as electron microscopy. "Amorphous" thin films were obtained by quick evaporation of solvent. Slow solvent removal during film for...
متن کاملChronic Toxicity of Di-n-butyl and Di-n-octyl Phthalate to Daphnia Magna and the Fathead Minnow
The toxicities of di-n-butyl phthalate (DBP) and di-n-octyl phthalate (DOP) were assessed by measuring the effect of exposure to these compounds on the fecundity of Daphnia magna and on the hatching and survival of the early life stages of the fathead minnow Pimephales promelas. For D. magna, exposure to 1.8 mg/L DBP or 1.0 mg/L DOP caused a significant reduction in reproduction. Doses of 0.56 ...

About 20 years have elapsed since those studies were done. During this period, many changes that might influence teenage reproductive behavior and how it is viewed have taken place within the industrialized world. The proportion of births to unmarried women has risen,2 and nonmarital childbearing is more acceptable, both among adolescents and among women older than 20. Access to contraception a...
متن کامل1,2-Di-2-furylethane-1,2-dione
The title compound, C(10)H(6)O(4), lies across a twofold rotation axis through the midpoint of the C-C bond between the two carbonyl groups. The furan ring plane and the plane through all atoms are inclined at 23.88 (1)°. In the crystal structure, weak C-H⋯O hydrogen bonds form sheets in the bc plane and columns down the c axis.
