A Polymer-based Piezoelectric Vibration Energy Harvester with a 3D Meshed-Core Structure Takuya Tsukamoto1, Yohei Umino1, Kotaro Hashikura1, Sachie Shiomi1, Kou Yamada1, Takaaki Suzuki1,2 1Gunma University, 2JST PRESTO In this study, we fabricated a flexible 3D mesh structure and applied it to the elastic layer of a bimorph cantilever-type vibration energy harvester for the purpose of lowering resonance frequency and increasing output power.
Generation and Control of Electrohydrodynamic Flows in Aqueous Electrolyte Solutions Kentaro Doi1, Fumika Nito1, Ayako Yano2, Ryo Nagura1, Satoyuki Kawano1 1Department of Mechanical Science and Bioengineering, Graduate School of Engineering Science, Osaka University, 2Division of Mechanical Science and Technology, Faculty of Science and Technology, GUNMA University The rectification of ion transport pathways is an effective method to generate one-directional ion-dragged electrohydrodynamic flows. By setting an ion-exchange membrane in a flow channel, an electrically polarized condition is generated and causes a liquid flow to be driven when an electric field is externally applied.
One-step Protocol for Evaluation of the Mode of Radiation-induced Clonogenic Cell Death by Fluorescence Microscopy Daijiro Kobayashi1, Atsushi Shibata2, Takahiro Oike1, Takashi Nakano1 1Department of Radiation Oncology, Gunma University Graduate School of Medicine, 2Advanced Scientific Research Leaders Development Unit, Gunma University Graduate School of Medicine Research on ionizing radiation (IR)-induced clonogenic cell death is important for understanding the effects of IR on malignant tumors and normal tissues. Here, we describe a one-step assay for assessing the major modes of IR-induced clonogenic cell death based on morphology of 4',6-diamidino-2-phenylindole dihydrochloride (DAPI)-stained nuclei visualized by fluorescence microscopy.
