| Preliminary scope of work in English |
| A nanofluid is a mixture consisting of nanometer-sized particulates (nanoparticles, nanotubes, etc.) dispersed in a liquid base. The nano-objects may be very diverse, including metals and metal oxide nanoparticles (NPs), carbon nanotubes, graphene sheets, etc. Typical liquid matrices involve water-based solutions, ethylene glycol, ionic liquids, and oils.
Let’s have fun…but on a physical basis! The student will prepare differently colored nanofluids (and learn how to manipulate with the color) by a plasma-based method that has never been used before. We will match seemingly unmatchable: metal nanoparticles produced in a gas phase by magnetron sputtering, and liquids. We will choose the metals that exhibit Localized Surface Plasmon Resonance (LSPR) in the visible light range (Ag, Cu, Au) and liquid polymers that are characterized by low vapor pressure. The goal is to understand how the concentration, size distribution, and mixing of the nanoparticles influence the LSPR and the color of the nanofluid. |
