A team of researchers from Indian Institute of Science, Bengaluru, Université Paris-Saclay, Gif-sur-Yvette, France and Technische Universität München, Germany has provided a material design strategy for polycrystalline piezoelectrics that could achieve electrostrain values larger than 1%. The breakthrough could result in cheaper and efficient piezoelectric actuators.
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.
