Volatile first solvent (clear) is removed (e.g. evaporation) from first mixed solvent system (green) to give a second mixed solvent system (dark-green) Second mixed solvent system (dark-green) allowed to cool overtime to give crystals (orange) and a non-saturated second mixed solvent system (green-blue)
This Wikipedia page provides a comprehensive list of boiling and freezing points for various solvents.
Solvent vapor annealing (SVA) is a widely used technique for controlling the morphology and ordering of block copolymer (BCP) films. [1] [2] [3] By controlling the block ratio (f = NA/N), spheres, cylinders, gyroids, and lamellae structures can be generated by forming a swollen and mobile layer of thin-film from added solvent vapor to facilitate the self-assembly of the polymer blocks.

Evaporation is a type of vaporization that occurs on the surface of a liquid as it changes into the gas phase. [1] A high concentration of the evaporating substance in the surrounding gas significantly slows down evaporation, such as when humidity affects rate of evaporation of water. [2]
Many solvents are volatile and can easily be evaporated using rotary evaporation. Even less volatile solvents can be removed by rotary evaporation under high vacuum and with heating. It is also used by environmental regulatory agencies for determining the amount of solvents in paints, coatings and inks. [8]
Affects the traveling time of the polymer jet; should be high enough to allow complete evaporation of the solvent. Voltage, Feed rate: Feed rate: Determines the amount of solution available per unit of time. Influences the jet velocity and the material transfer rate. Increasing the rate causes more polymer to be processed at a given instant ...
Evaporation is the elimination of the solvent in form of vapor from a solution. For most evaporation systems, the solvent is water and the heat is provided by steam condensation. [ 4 ] In a forced circulation evaporation liquid is constantly circulated through the system.
Evaporation of solvent from the droplets to form dried particles. Particle charging using an ion jet formed via corona discharge. Particle selection – an ion trap is used to excess ions and high mobility charged particles. Measurement of the aggregate charge of aerosol particles using a filter/electrometer.
