Forming core-shell microcapsules

A microcapsule formation system comprising:

• a first container containing a core material;
• a second container containing a shell material;
• one or more container heaters in mechanical contact with the first and second containers, the one or more container heaters operable to heat the core and shell materials to a temperature between 0° C. and 250° C.;
• a first pair of syringe pumps operable to pump the heated core material from the first container to an encapsulation cell at a first volumetric rate and a first pressure by alternating the pumping between each syringe pump of the first pair of syringe pumps;
• a second pair of syringe pumps operable to pump the heated shell material from the first container to the encapsulation cell at a second volumetric rate and a second pressure by alternating the pumping between each syringe pump of the second pair of syringe pumps;
• one or more syringe heaters in mechanical contact with the first and second pairs of syringe pumps, the one or more heaters operable to heat the core and shell materials while the core and shell materials are pumped by the syringe pumps;
• a vibration source operable to vibrate the encapsulation cell;
• the encapsulation cell comprising an inner nozzle concentrically disposed within an outer nozzle, the inner and outer nozzles operable to form a microcapsule using the core material and the shell material while the encapsulation cell is vibrated by the vibration source;
• and
• a processor operable to control the one or more container heaters, the first and second pair of syringe pumps, and the vibration source.
