Towards novel promising perovskite-type ferroelectric materials: High-pressure synthesis of rubidium niobate source: Shibaura Institute of TechnologyCapacitors are crucial components in electronic devices such as smartphones and computers. They are made of dielectric materials that polarize on the application of the voltage. Currently, barium titanate (BaTiO3) is the most widely used material for capacitors.Barium titanate belongs to the perovskite group of materials, where a titanium ion resides within an oxygen octahedral cage. The material exhibits displacive-type ferroelectric ...

source:cosmosCombining one of the world’s rarest metals with a comparatively abundant element could help accelerate green hydrogen production, with a Japanese research team developing an enhanced catalyst for industrial electrolysis.Iridium is a vital, but rare catalyst involved in the electrolysis process that produces green hydrogen, effectively by using electricity from a renewable energy source to split water into separate hydrogen and oxygen molecules.Such is its scarcity that only around 3 tonnes are produced annually from a thin layer of the Earth’s crust and other small deposits. It’s ...
