nanoliquid

Nanoliquid refers to a liquid that contains nanoparticles dispersed within it. These nanoparticles are typically in the size range of 1 to 100 nanometers. The inclusion of nanoparticles can significantly alter the physical and chemical properties of the base liquid, leading to enhanced performance in various applications. For instance, the thermal conductivity of a fluid can be increased by adding metallic or oxide nanoparticles, creating a nanofluid. These nanofluids are explored for their potential in heat transfer applications such as cooling systems in electronics and solar thermal collectors.

Beyond thermal properties, nanoliquids can exhibit modified optical, electrical, and mechanical characteristics. Depending on the type and concentration of nanoparticles, the viscosity, surface tension, and reactivity of the liquid can be tuned. Applications are being investigated in areas like lubrication, drug delivery, sensors, and advanced coatings. The stability of nanoparticle dispersion is a critical factor in the efficacy of nanoliquids, and various surface modification techniques are employed to prevent aggregation and settling. Research in nanoliquids is an active field, focusing on understanding the fundamental interactions between nanoparticles and the base fluid, as well as developing scalable and cost-effective production methods.
