Nanoparticle-Enhanced Ionic Liquids (NEILs): Heat Transfer Fluids with high volumetric heat capacity as well as favorable physical properties to improve the efficiency of CSP systems

A good HTF must be able to absorb a substantial amount of energy in a given volume, a property known as volumetric heat capacity. Physical properties such as viscosity, thermal stability, and thermal conductivity must also be considered. Ionic liquids (IL) were discovered more than 30 years ago and...

NAPL Calculator: Software application that will determine if non-aqueous phase liquid (NAPL) contaminants are present in soil, groundwater, or soil vapor samples

An environmental engineer at the Savannah River Site has developed a software application that will determine if non-aqueous phase liquid (NAPL) contaminants are present in soil, groundwater, or soil vapor samples. The software will determine both the quantity and composition of NAPL chemicals in...
