Also, as a new approach to the subject, by ab initio molecular dynamics (AIMD) simulations and neutron-diffraction experiments, the mechanism is shown that the oxide ions migrate by the breaking and reforming of M2O9 (M = Nb, Mo) dimers, MO5 monomers and MO4 tetrahedra. The oxide-ion migration is reminiscent of a concerted push-pull interstitialcy ‘bucket-relay’-type motions. Readers can understand the oxide-ion and proton migration mechanism in terms of crystal structure.\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan\u003eRecently, materials that exhibit high ionic conductivity have been discovered one after another.\u003c\/span\u003e\u003c\/p\u003e","brand":"Springer Nature Switzerland AG","offers":[{"title":"Paperback","offer_id":47854021312663,"sku":"9789819625543","price":14411.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0666\/3471\/1191\/files\/9789819625543.webp?v=1780038092","url":"https:\/\/atlanticbooks.com\/products\/discovery-of-ba7nb4moo20based-materials-and-the-mechanism-of-ultrafast-ion-conduction-via-dimers-9789819625543","provider":"Atlantic Books","version":"1.0","type":"link"}
