Patent number: 8236251Abstract: Suppression or enhancement of various properties of a liquid fluid is aimed by improving uniform dispersion of nanoparticles by means of making a state in which no oxidized film exists on the surfaces of the nanoparticles to be dispersed in the liquid fluid. The location of the liquid fluid is confirmed with ease by enhancing the brightness of light emission of the fluid through uniform dispersion of the nanoparticles in the liquid fluid containing a material having a flame reaction. In this way, as to liquid fluids utilized in various industries, it is possible to offer a technology to desirably enhance or suppress a property desired to be enhanced and a property desired to be suppressed among various properties that its constituents have.Type: GrantFiled: August 5, 2010Date of Patent: August 7, 2012Assignee: Japan Nuclear Cycle Development InstituteInventors: Mikio Toda, Toshiro Nishi, Nobuki Oka, Hiroyuki Tsutaya, Kuniaki Ara, Hiroaki Ohira, Kazuya Kurome, Naoki Yoshioka
