In this paper, we show that magnetic nanowires with weak magnetic fields and low frequencies can induce cell death via a mechanism that does not involve heat production. We incubated colon cancer cells with two concentrations (2.4 and 12 μg/mL) of nickel nanowires that were 35 nm in diameter and exposed the cells and nanowires to an alternating magnetic field (0.5 mT and 1 Hz or 1 kHz) for 10 o...

Katsumi Ohata* Junichi Sato* ABSTRACT: Magnetic shielding for strong magnets using a high-temperature superconductor that can be operated at liquid nitrogen temperature has been studied. Long and large-cross-section (9 mm wide and 0.5 mm thick) 54-filament Bi-2223/Ag tape was developed. Double pancake coils were wound using the tapes having sufficient bending strain tolerance for the react-and-...

Replacing organic liquid electrolytes with solid electrolytes has led to a new perspective on batteries, enabling high-energy battery chemistry with intrinsically safe cell designs. However, most solid/gel electrolytes are easily deformed; under extreme deformation, leakage and/or short-circuiting can occur. Here, we report a novel magneto-rheological electrolyte (MR electrolyte) that responds ...

Background: Hydatidosis it is a zoonotic disease which is caused by the larval stages of different species of the tapeworms (Cestoda) of genus Echinococcus. Currently, the surgery is most definitive method of treatment for Hydatid Cyst, but always there is the risk of leakage or rupture during the surgery, therefore it is considered unreliable method. Methods: Protoscoleces of hydatid cysts we...

Multi-information fusion is the trend of NDT equipments. This paper describes the principle, configuration and application of EMS-2003 —– a new device combining metal magnetic memory, eddy current and magnetic flux leakage testing techniques. By using the three complementary NDT techniques, we are able to make complete testing and analysis on early damages and established defects in in-service ...
