Stability and thermal conductivity of different nano-composite material prepared for thermal energy storage applications

The interest in solar energy applications doubles due to the necessities of the stage, and because of it, the interest in heat storage materials expands, the most important of which is paraffins. Paraffins suffer from low thermal conductivity, so many researchers have added nanomaterials that improv...
