Electric-field Control of Electronic States in WS2 Nanodevices by Electrolyte Gating Feng Qin1, Toshiya Ideue1, Wu Shi2, Yijin Zhang3,4, Ryuji Suzuki1, Masaro Yoshida5, Yu Saito1, Yoshihiro Iwasa1,5 1Quantum-Phase Electronics Center (QPEC) and Department of Applied Physics, The University of Tokyo, 2Materials Sciences Division, Lawrence Berkeley National Laboratory, 3Institute of Scientific and Industrial Research, Osaka University, 4Max Planck Institute for Solid State Research, 5RIKEN Center for Emergent Matter Science (CEMS) Here, we present a protocol to control the carrier number in solids by using the electrolyte.
Visualization of Thalamocortical Axon Branching and Synapse Formation in Organotypic Cocultures Naoyuki Matsumoto1,2, Nobuhiko Yamamoto2 1Department of Medical Neuroscience, Graduate School of Medical Sciences, Kanazawa University, 2Neuroscience Laboratories, Graduate School of Frontier Biosciences, Osaka University This protocol describes a method for simultaneous imaging of thalamocortical axon branching and synapse formation in organotypic cocultures of the thalamus and cerebral cortex. Individual thalamocortical axons and their presynaptic terminals are visualized by a single cell electroporation technique with DsRed and GFP-tagged synaptophysin.
Real-time Tracking of DNA Fragment Separation by Smartphone Chunxian Tao1, Bo Yang1, Zhenqing Li1, Dawei Zhang1, Yoshinori Yamaguchi1,2,3 1Shanghai Key Lab of Modern Optical System, University of Shanghai for Science and Technology, 2Department of Applied Physics, Graduate School of Engineering, Osaka University, 3East China University of Science and Technology, Department of Physics Faculty of Science Traditional slab gel electrophoresis (SGE) experiments require a complicated apparatus and high chemical consumption. This work presents a protocol that describes a low-cost method to separate DNA fragments within a short timeframe.
