source:TOHOKU UNIVERSITYResearchers have pioneered a breakthrough in ferroelectric material development. They've engineered a novel displacement-type ferroelectric material boasting remarkable dielectric properties. Their achievement includes the successful synthesis of rubidium niobate (RbNbO3), a compound previously deemed challenging to produce under pressures exceeding 40,000 atmospheres. Additionally, they characterized how polarization changes across a wide temperature range during phase transitions. This breakthrough can lead to new design guidelines for ferroelectric materials.Capa...

source: Tohoku UniversityAn international group of researchers has developed a novel approach that enhances the efficiency of the oxygen evolution reaction (OER), a key process in renewable energy technologies. By introducing rare earth single atoms into manganese oxide (MnO2), the group successfully modulated oxygen electronic states, leading to unprecedented improvements in OER performance.Their findings were published in the journal Nano Energy on June 10, 2024.Transition-metal-based oxides have been widely explored for their potential as active OER catalysts. However, the capacity of these...
