Thermo-physical properties and corrosivity improvement of molten salts by use of nanoparticles for concentrated solar power applications: a critical review

Molten salts (MSs) are known for their advantages, such as being cheap, abundant in supply and can be operated at high temperatures. These advantages permit them for potential application as sensible storage media and heat transfer fluid (HTF) for concentrated solar power (CSP) plants. However, the...
