    Publication date: February 24, 2011
    Applicant: BLH Ecology Concepts, L.L.C.
    Inventors: Katsuto Otake, Hitoshi Takebayashi, Masahiko Yokosuka
  • Process for producing liposome and apparatus therefor
    Publication number: 20040099976
    Abstract: A method for producing liposome encapsulating a desired substance is provided. The method is characteristic in that an aqueous phase containing the substance to be encapsulated is added to a homogenous fluid mixture of a phospholipid or a glycolipid and carbon dioxide either under a supercritical condition or under a condition in which temperature or pressure is higher than or equal to its critical point. This method makes it possible to produce liposomes with improved trapping efficiency in fewer steps and without using harmful organic solvents.
    Type: Application

  • Method of decomposing polychlorobiphenyls
    Patent number: 6124519
    Abstract: A method of decomposing a polychlorobiphenyl compound-containing material into an unharmful state, wherein the material is treated with a supercritical water containing an alkaline substance at a temperature higher than the critical temperature of water and a pressure higher than the critical pressure of water.
    Type: Grant
    Filed: December 12, 1997
    Date of Patent: September 26, 2000
    Assignee: Director-General of Agency of Industrial Science and Technology
