High-Dielectric-Permittivity Layered Nitride CaTiN₂

Preparation of iron(IV) nitridoferrate Ca4FeN4 through azide-mediated oxidation under high-pressure conditions

“…The range of observed Ca–N distances (2.43 < d Ca–N < 2.82 Å, Supplementary Fig. 2 and Supplementary Table 4 ) is in good agreement with values found in other Ca nitridoferrates like Ca 2 FeN 2 and Ca 6 FeN 5 (2.33 < d Ca–N < 2.74 Å) and Ca nitridometallates like CaTiN 2 , Ca 4 TiN 4 , and Ca 3 CrN 3 (2.37 < d Ca–N < 2.85 Å) 20 , 23 , 41 , 47 , 48 .…”

“…The large group of ternary transition metal nitrides A x M y N z , in which A is an electropositive metal, also have a rich variety of electronic, physical, and magnetic properties [20][21][22][23][24][25][26][27][28] , but their synthesis suffers from the limitation that the starting materials, e.g. binary transition metal nitrides or pure metals, usually feature lower oxidation states than the targeted compounds, for example, Mn 4 N vs. Ca 6 Mn III N 5 29 .…”

Mechanochemical‐Assisted Synthesis of High‐Entropy Metal Nitride via a Soft Urea Strategy

“…Needless to say, the fabrication of these multimetal‐type metal nitrides is of considerable interest . Although many binary and ternary nitrides have been successfully prepared by combining two metal nitrides, or inserting a third metal, such as lithium, into a single metal nitride, these methods exhibit obvious drawbacks, such as a complicated synthetic procedure and limited applicability. As such, developing new strategies for facile fabrication of multimetal metal nitrides is particularly important.…”

Rare earth elements based oxide ion conductors

“…Therefore, the search for new energy strategies to meet energy demands and reduce exhaust gas emissions has attracted widespread attention. [7][8][9][10][11][12] As an electrochemical device, solid oxide fuel cells (SOFCs) are all-solid-state systems that can efficiently generate electricity via conversion from fuels and is also not limited by the Carnot cycle efficiency. Therefore, SOFCs have become a sustainable energy technology for the future, owing to several critical advantages such as high overall energy efficiency (up to 80%), fuel flexibility, and relatively low catalyst cost.…”
