Abstract

In this study, the bipolar switching properties and electrical conduction behaviors of the ITO thin films RRAM devices were investigated. For the transparent RRAM devices structure, indium tin oxide thin films were deposited by using the RF magnetron sputtering method on the ITO/glass substrate. For the ITO/ITOX/ITO/glass (MIM) structure, an indium tin oxide thin film top electrode was prepared to form the transparent RRAM devices. From the experimental results, the 102 On/Off memory ratio and bipolar switching cycling properties for set/reset stable states were found and discussed. All transparent RRAM devices exhibited the obvious memory window and low set voltage for the switching times of 120 cycles. The electrical transport mechanisms were dominated by the ohmic contact and space charge limit conduction (SCLC) models for set and reset states. Finally, the transmittances properties of the transparent ITO/ITOX/ITO RRAM devices for the different oxygen growth procedures were about 90% according to the UV–Vis spectrophotometer for the visible wavelength range.

Biology (General), QH301-705.5
Abstract

Metabolomic is an emerging field of system biology. Lipidomic, a branch of metabolomic, aims to characterize lipophilic metabolites in biological systems. Caenorhabditis elegans (C. elegans) is a genetically tractable and versatile animal model for novel discovery of lipid metabolism. In addition, C. elegans embryo is simple and homogeneous. Here, we demonstrate detailed procedures of C. elegans culture, embryo isolation, lipid extraction and metabolomic data analysis.

Abstract

Objective To investigate the neuroprotective effect and its mechanism of n-butanol extract (n-BuE) of Chinese toon seeds on mouse with ischemia-reperfusion (I-R) injury of the brain in vivo. Methods The brain I-R model was established in 42 mice by ligation of bilateral common carotid arteries for 2 times combined with injection of sodium nitroprusside. Animals were randomly divided into 6 groups (7 each): sham-operated group, I-R model group, vehicle control group, two treatment groups [treated with n-BuE of Chinese toon seeds 28mg/(kg.d) or 42mg/(kg.d), respectirely, for 7 days], and positive control group [treated with aspirin 14mg/(kg. d)]. The animals were sacrificed by decapitation after the experimental procedure, and the water content of brain tissue was determined by weighing. The permeability of the blood brain barrier was evaluated by measurement of Evans blue (EB) content with spectrophotometer. The contents of malondialdehyde (MDA) and nitrogen mono-oxide (NO), and the activities of superoxide dismutase (SOD) and glutathione peroxidase (GPX) in brain tissue were determined with spectrophotometer. Results The water content and EB content of brain tissue, and the contents of MDA and NO, and the activities of SOD and GPX in hippocampal tissue increased significantly in I-R model group than in sham-operation group (P
