Physical instability suppression of microencapsulated phase change material(MPCM) suspensions

Thermophysical Properties Characterization of Microencapsulated Phase Change Material Slurry

Hydrodynamic suppression of phase separation in active suspensions.

We simulate with hydrodynamics a suspension of active disks squirming through a Newtonian fluid. We explore numerically the full range of squirmer area fractions from dilute to close packed and show that "motility induced phase separation," which was recently proposed to arise generically in active matter, and which has been seen in simulations of active Brownian disks, is strongly suppressed b...

Microencapsulated Carbon Black Suspensions for Restoration of Electrical Conductivity

Damage triggered release of microencapsulated conductive core materials has enabled autonomous restoration of electrical conductivity in a broken circuit. [ 1,2 ] Encapsulation of several different types of conductive core materials has been reported in the literature. [ 2–8 ] Odom et al. observed the formation of conductive charge transfer salt on a broken circuit upon the release of two react...

Synthesis of a paraffin phase change material microencapsulated in a siloxane polymer

The coemulsification method suitable for the formulation of microcapsules of n-eicosane coated with a polysiloxane is developed. This method allows to synthesize core-shell microcapsules of paraffin which have the shape of spheres or distorted spheres and are designed for the use as phase change materials. The microcapsules are formed in aqueous phase by the precipitation of n-eicosane together...

Influence of Microencapsulated Phase Change Material (PCM) Addition on (Micro) Mechanical Properties of Cement Paste

Excessive cracking can be a serious durability problem for reinforced concrete structures. In recent years, addition of microencapsulated phase change materials (PCMs) to concrete has been proposed as a possible solution to crack formation related to temperature gradients. However, the addition of PCM microcapsules to cementitious materials can have some drawbacks, mainly related to strength re...
