background: abnormal oocyte morphology has been associated with the hormonal environment to which the gametes are exposed. objective: in this study, we evaluated the oocytes morphology, fertilization rate, embryos quality, and implantation rate resulted of retrieved oocytes in different times after human chorionic gonadotrophin (hcg) administration. materials and methods: a total of 985 metapha...

Unique properties of carbon nanofibers (CNF) depends on its microstructure and bulk morphology, which are governed by catalysts, carbon sources and synthesis conditions in the catalytic growth of CNF. Hence, exact understanding of the structure of CNF is important to achieve best performance of the CNF in practical applications. In a previous work [1], the present authors have proposed that the...
