As to actually creating a solid particle, I have no idea how that would be possible. However, "aerosol", although etymologically meaning _solid_ particles suspended in a gas (as in smoke), it also often used referring to mists (droplets of liquid in a gas - what actually comes out of an "aerosol can"). "Creating" droplets of liquid (or rather, causing them to from out of oversaturated vapor) is something totally different, it's the principle of the Wilson Cloud Chamber - ionizing radiation ionizes molecules in the atmosphere, which act as condensation nuclei.
