US Patent 7837805 Methods for treating surfaces

Some embodiments include methods of treating surfaces with aerosol particles. The aerosol particles may be formed as liquid particles, and then passed through a chamber under conditions which change the elasticity of the particles prior to impacting a surface with the particles. The change in elasticity may be an increase in the elasticity, or a decrease in the elasticity. The change in elasticity may be accomplished by causing a phase change of one or more components of the aerosol particles such as, for example, by at least partially freezing the aerosol particles, or by forming entrained bubbles within the aerosol particles. Some embodiments include apparatuses that may be utilized during treatment of surfaces with aerosol particles.
