Li-ion and Li-S batteries find enormous applications in different fields, such as electric vehicles and portable electronics. A separator is an indispensable part of the battery design, which functions as a physical barrier for the electrode as well as an electrolyte reservoir for ionic transport. The properties of the separators directly influence the(More)
Oocyte cryopreservation has a great impact on subsequent embryonic development. Currently, several studies have primarily focused on the consequences of vitrification and the development potential of cellular structures. This study determined whether oocyte vitrification caused epigenetic instabilities of bovine embryos. The effects of oocyte vitrification(More)
Article history: Received 1 July 2015 Received in revised form 23 September 2015 Accepted 30 November 2015 Available online xxxx Resistive switching (RS) characteristics of TiO2/HfO2 bilayer memory devices annealed under N2 and O2 ambient were investigated in this work. It was found that the improved RS properties were obtained in N2 annealing atmosphere,(More)
The aim of this study was to assess the effect of insulin-like growth factor-1 (IGF-1) on the developmental competence of somatic cell nuclear transfer (SCNT) bovine embryos. First, the expression levels of IGF-1 receptor (IGF-1R) and IGF-1 in the oocytes and embryos of different developmental stages were examined. Then the effects of exogenous IGF-1 on the(More)
