Future deployment of wireless sensor networks will ultimately require a self-sustainable local power source for each sensor, and vibration energy harvesting is a promising approach for such applications. A requirement for efficient vibration energy harvesting is to match the device and source frequencies. While techniques to tune the resonance frequency of an energy harvesting device have recen...

Liposomal magnetofection is the most powerful nonviral method for the nucleic acid delivery into the cultured cancer cells and widely used for in vitro applications. Use of the static magnetic field condition may result in non-uniform distribution of aggregate complexes on the surface of cultured cells. To prevent this, we developed the new device which allows to concentrate aggregate complexes...

Teruo Kohashi, Dr. Sc. Kumi Motai, Dr. Sc. OVERVIEW: Electron microscope technology developed by Hitachi is used for testing and analysis of a wide range of semiconductors and other hardware devices. Spin SEMs are able to observe the magnetic structure of a device at the nanometer scale and are already used for applications such as evaluating the shape of storage bits on magnetic media. Hitachi...

Background: Previous studies have shown that exposure to electromagnetic fields produced by magnetic resonance imaging or mobile phones can lead to increased microleakage of dental amalgam.Objective: The aim of the present study was to investigate the effect of electromagnetic field of a commercial dental light cure device and a common GSM mobile phone on microleakage of amalgam restorations.Ma...
