    Effect of salinomycin on broiler performance
    (2006) Demirulus H.; Eratak S.; Kara K.
    In this study, effects of salinomycin on broiler performance were evaluated. Six levels of salinomycin added to feed were tested (0, 1, 3, 5, 7 or 9 ppm, respectively) for 49 days. Increasing the level resulted in a decrease in body weight, feed intake, weight gain and feed efficiency. The highest body and neck weight (1972.5 and 90.9 g) and the best feed efficiency (1.59) were obtained with 1 ppm salinomycin (p<0.05). The best viability rate (96%) was obtained with 3 ppm salinomycin (p<0.05). The highest plucked, carcass, tight, wing, breast and back weight of the group were 1629.1, 1316.9, 399.0, 150.0, 440.0 and 300.7 g, respectively. The highest abdominal fat weight (36.8 g) observed with 7 ppm salinomycin used group (p<0.05). © 2006 Asian Network for Scientific Information.

    Surface modification of CdSeS nanocrystals for polymer hybrid solar cells
    (Royal Society of Chemistry, 2016) Erdogan A.; Karakaya C.; Gonce M.K.; Buyukcelebi S.; Yenel E.; Kara K.; Ozcivan A.N.; Can M.; Kus M.; Demic S.
    We report the synthesis of fluorene-carbazole derivatives as capping agents for CdSeS nanocrystals and present their performance in polymer hybrid solar cells. CdSeS nanocrystals and different ligands consisting of fluorene and carbazole units were synthesized and characterized. Both oleic acid and pyridine capped CdSeS nanocrystals were used as reference materials in polymer hybrid solar cells. We observed that our synthesized materials show better efficiencies depending on their structures. In comparison with the reference cells consisting of pyridine capped CdSeS nanocrystals, ligand capped CdSeS shows better efficiency due to electron withdrawing and accepting groups in its structure. The reason behind the superiority of our ligands compared to the reference pyridine is the donor and/or acceptor based compatibility of the combined structures and effective surface modification as well. © 2016 The Royal Society of Chemistry.
