Phase change composites of octadecane and gallium with expanded graphite as a carrier

Abstract

The thermophysical properties of the novel phase change composites formed by simultaneously packing octadecane and gallium with expanded graphite as carrier can be adjusted in a wide range, creating more options for related fields.

Healable supramolecular micelle/nano-encapsulated metal composite phase change material for thermal energy storage

“…It was found that the melting and solidifying temperature peaks of CPCSMs and DSC thermal properties of PCSM are consistent with the previous results. 31 However, composite PCSMs revealed broader and shorter endothermic and exothermic bands compared to PCSM. In addition, the peaks slightly shifted to the left for PCSM and its thermal temperatures were slightly reduced, which is attributed to the addition of silver, mechanically reinforcing and thermally stabilizing the synthesized materials.…”

Fabrication and Thermal Properties of a Gallium and Porous Foam Composite Phase Change Material

“…Small samples of gallium have been seen to supercool to as low as −184 °C, over 200 °C below its melting point, before crystallization occurs . The degree of supercooling has been seen to depend on previous peak temperatures and can be altered with surface area enhancements or nucleating agents. , …”

“…42 The degree of supercooling has been seen to depend on previous peak temperatures and can be altered with surface area enhancements or nucleating agents. 43,44 The integration of the porous metal foam was seen to benefit gallium's supercooling, as shown in Figure 11. Bulk gallium (∼100 mg) was observed to crystallize approximately 50−60 °C below the melting point.…”

Cyaonoside A-loaded composite hydrogel microspheres to treat osteoarthritis by relieving chondrocyte inflammation

“…In addition, since the microspheres will come into direct contact with the articular cartilage after being injected into the joint cavity, their biocompatibility should be taken into account. 58,59 Hemolytic assays showed that neither blank HAMA microspheres nor HLC composite microspheres significantly triggered rat erythrocyte rupture (Fig. 5F and G).…”
