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.
Researchers have identified urban sewage as a critical hotspot for the evolution and spread of drug-resistant bacteria, highlighting an urgent need for nationwide wastewater monitoring to prevent future health crises.
