High electrostrain in a lead-free piezoceramic from a chemopiezoelectric effect The authors demonstrate a chemopiezoelectric effect in which the displacive migration of oxygen vacancies driven by an electric field induces a large strain in the surface layer of thin (K,Na)NbO3ceramics. They achiev...
A new study targets feature selection, a key step in machine learning where the algorithm determines which parts of the input data are most relevant to making accurate predictions. The hidden cost of human disturbance on California’s sea otters ...
Excellent hardening effect in lead-free piezoceramics by embedding local Cu-doped defect dipoles in phase boundary engineering There is a long-standing trade-off between piezoelectric coefficient and mechanical quality factor for piezoceramics. Here, authors embed local defect dipoles into phase boundary...
With the urgent need for sustainable alternatives to fossil fuels, which currently make up around 80% of the global energy mix, metal fuels are emerging as carbon-free and recyclable energy carriers, particularly for the long-term storage and … ...
