The invention provides a method for producing bubbles that exhibit an excellent monodispersity. The invention relates to a method for generating bubbles by the injection and dispersion of a gas through a porous body into a liquid, wherein the value produced by dividing the pore diameter that accounts for 10% of the total pore volume in the relative cumulative pore distribution curve of the porous body by the pore diameter that accounts for 90% of the total pore volume in the relative cumulative pore dismeter distribution curve of the porous body is 1 to 1.5.

Method for producing monodisperse bubbles

It is an object of the present invention to provide spherical metal particles having excellent monodispersity. The present invention relates to a method of manufacturing monodisperse spherical metal particles characterized by passing liquid metal through a porous membrane so as to disperse the resulting liquid metal particles in a continuous liquid phase.

Monodisperse spherical metal particles and manufacturing method therefor

The invention provides monodisperse single emulsions which have a mean emulsion particle size within the range of 0.3 to 40 .mu.m and are substantially free of emulsion particles having a particle size smaller than 50% of the mean particle size, double emulsions which have a mean emulsion particle size within the range of 0.3 to 40 .mu.m and whose internal phase concentration is controlled substantially uniformly within the range of 1% to 70%, and methods of producing these emulsions.
