Abstract: The present invention relates to substrates comprising a network comprising core shell liquid metal encapsulates comprising multi-functional ligands and processes of making and using such substrates. The core shell liquid metal particles are linked via ligands to form such network. Such networks volumetric conductivity increases under strain which maintains a substrate's resistance under strain. The constant resistance results in consistent thermal heating via resistive heating. Thus allowing a substrate that comprises such network to serve as an effective heat provider.

Abstract: The rotary tablet press comprises a machine base assembly and detachable module. Granulation is fed into the module from the hopper and travels into the feeder chamber. The base assembly comprises motorized pressure roll assemblies and a turret drive assembly. The detachable module comprises a module base, turret base, turret, cam body, cams, feeder, tablet discharge chute, hopper, upper enclosure, and guard doors. The rotary turret comprises upper punches, dies, and lower punches. As the turret rotates, the dies move underneath the feeder chamber. The rotary feeder paddles move the granulation and assist with feeding powder to the dies. Punches travel along cam tracks as the turret rotates and compresses the powder into a tablet when the punches contact the pressure rolls. An ejection cam pushes the lower punch in the upward direction and a take-off bar mounted just above the die table directs the tablet into a discharge chute. The detachable module is sealed by incorporating an upper enclosure.
