High accumulations of phytoplankton species that produce toxins are referred to as harmful algal blooms (HABs). HABs represent one of the most important sources of contamination in marine environments, as well as a serious threat to public health, fisheries, aquaculture-based industries, and tourism. Therefore, methods effectively controlling HABs with minimal impact on marine ecology are required.

The tests performed show that the studied nanofluids present non-Newtonian shear-thinning behaviour.

- The study investigates the dispersion and stability of Al2O3 nanoparticles in ethylene glycol at up to 25% concentration, focusing on their thermal conductivity and viscosity at temperatures between 283.15 K and 323.15 K.
- Experimental results show that increasing nanoparticle concentration enhances thermal conductivity by up to 19%, while viscosity is more than doubled compared to the base fluid; viscosity decreases and thermal conductivity increases with rising temperatures.
- The research also explores how particle size affects viscosity and compares the experimental findings with theoretical models for validating the results.
