Nano-rust: Smart additive for autonomous temperature control

The right temperature matters—whether in technical processes, for the quality of food and medicines, or the lifetime of electronic components and batteries. For this purpose, temperature indicators record (un)desired temperature increases that can be read out later. Researchers in the group led by Prof. Dr. Karl Mandel, professor of inorganic chemistry at FAU, have succeeded in developing a novel temperature indicator in the form of a micrometer-sized particle whose central component is rust. The results of the research have been published in the journal Advanced Materials.
