| Research Abstract |
Magnetic field effects (MFEs) on chemical and physical prooses were reseatched by using vertical magnetic fields generated by a 15 T and 1500 Pim superconducting magnet. 1. Cherry tomato, water, frog, and others are magnetically levitated by the magnet. Plastic chips are magnetically levitated and separated. Magnetic levitation is a useful technique fix separation of diamagnetic materials and cliainagnetic susoeptibility measurement. 2. Photoinchred thermal convection of benzene and water is controlled by application of high magnetic field. Magnetic field is a convenient tool for controlling Earth gravity-chiven phenomena sucb. as thermal and concentration induced convection. a With the aid of magnetic field, 3D-mcaphological chirality is induced in membrane tubes prepared by a silicate garden reaction. The results are explained by a boundary-assisted magnetohydrodynamics mechanism. 4 It is suggested to orient phorphine nanorods, tbiophene nanodusters, microtubulin and others using high magnetic fields, indicating that magnetic field is useful for nanostructure cont al. 5. Magnetic field influences oxidation state of cobalt ion photochemically deposited on titanium micropartides, though its mechanism is not clarified. 6. Photochemical reaction in mesoporous silica is significantly afiected by a magnetic field. Its mechanism is explainable by the radical pair mechanism. It is strongly suggested the hydrodynamics of the solution in the pore is very different from that in bullc. solution.
In conclusion, it is shown that magnetic field is a brand-new physical environment useful for materials science.
