P-90: The Effect of Nitric Oxide on Mouse Oocyte in Vitro Maturation in Two and Three Dimensional Conditions

Background: In vitro culture of ovarian follicles may preserve fertility in women with premature ovarian failure due to cancer .It seems that creation a condition that could maintain cellular communications and supports growth of follicles to produce mature oocytes appear to be essential. Nitric oxide (NO) has been recently shown to act with a dual action in mouse oocyte meiotic maturation depe...

The electrical transport properties in ZnO bulk, ZnMgO/ZnO and ZnMgO/ZnO/ZnMgO heterostructures

p { margin-bottom: 0.1in; direction: rtl; line-height: 120%; text-align: right; }a:link { color: rgb(0, 0, 255); } In this paper, the reported experimental data related to electrical transport properties in bulk ZnO, ZnMgO/ZnO and ZnMgO/ZnO/ZnMgO single and double heterostructures were analyzed quantitavely and the most important scattering parameters on controlling electron concentratio...

Skyrmion formation in magnetic thin films and heterostructures

Magnetic skyrmions are small magnetic domains that are topologically non-trivial as shown schematically in Fig. 1. They are characterized by a twist of the magnetization that forms a continuous winding of the magnetization across the domain. The topology is described by a quantized and conserved winding number. The term skyrmion arises from the original work of Skyrme some fifty years ago that ...

First-principles studies of a two-dimensional electron gas at the interface in ferroelectric oxide heterostructures

Approach to multifunctional device platform with epitaxial graphene on transition metal oxide

Heterostructures consisting of two-dimensional materials have shown new physical phenomena, novel electronic and optical properties, and new device concepts not observed in bulk material systems or purely three dimensional heterostructures. These new effects originated mostly from the van der Waals interaction between the different layers. Here we report that a new optical and electronic device...
