What if there was a more eco-friendly, passive way to heat or cool our homes and cars that also reduced our energy usage on a regular basis? After examining proof-of-concept “phase change inks” made with nanotechnology, a team of researchers from the University of Melbourne hoped to learn more about this. These inks might be used to regulate the environment, such as heating and cooling, in homes, cars, and buildings. The results of this study have the potential to lower global greenhouse gas emissions and energy use.”Phase change inks” that regulate environmental conditions like heating and cooling using nanotechnology.
