| Research Abstract |
With respect to nanoballs (spherical particles of nanometer size) of stainless steel alloy,the basic technology for making nanoballs by using the liquid glow discharge method,which had been developed by applicants, was upgraded. In particular, we enabled tohandle the particle size distribution of nanoballs, by changing applied voltage,magnetic field strength and electrolytic solution. Thus, it became possible to obtain astainless steel alloy nanoball with the world's smallest diameter of 2 ~ 3nm.Furthermore, we found this stainless steel alloy nanoball has a photocatalytic effectexpected for practical applications to a wide variety of devices.
