متن کاملEnhanced Thermo-Optical Switching of Paraffin-Wax Composite Spots under Laser Heating
Thermo-optical switches are of particular significance in communications networks where increasingly high switching speeds are required. Phase change materials (PCMs), in particular those based on paraffin wax, provide wealth of exciting applications with unusual thermally-induced switching properties, only limited by paraffin's rather low thermal conductivity. In this paper, the use of differe...

متن کامل3D Packaging Materials based on Graphite Nanoplatelet and Aluminum Nitride Nanocomposites
Nanostructured composites with efficient percolation networks are promising candidates for packaging materials due to their high thermal conductivity. In this study, we investigate the thermal conductivity of composites consisting of a combination of exfoliated graphene nanoplatelet (xGNP) and aluminum nitride (AlN) particles in polyvinylidine fluoride (PVDF) matrix. The surfaces of the AlN par...
