Research Progress of Phase Change Materials for Thermal Management in Electronic Components
Advanced Materials Interfaces, EarlyView.Phase change materials(PCMs) can effectively solve the overheating problem in electronic devices during use, but the low themal conductivity of PCM itself hinders its development. The problem of low thermal conductivity can be addressed by using metal fins, adding nanparticles and porous metal foams.

Advanced Materials Technologies, EarlyView.Molybdenum hexafluoride as a pretreatment is able to create a chemical contrast between SiN and SiO2 surfaces via selective fluorine passivation of the oxide. One dose of MoF6 enabled 9.7 nm of selective deposited TiO2 on SiN versus SiO2 with selectivity >0.92 on a nanoscale SiN/SiO2 patterned surface.
