Combining two electrochemical techniques, hydrogen permeation-based potentiometry (HPP) and electrochemical impedance spectroscopy (EIS), the researchers efficiently measured the coating degradation rates on the industrially relevant metal.
The study from IISc found a previously unidentified yeast-like symbiont inside the lac insect Kerria lacca, which gives the insect its distinctive red colour and, may also provide other nutrients in return for shelter.
