Abstract(J)	酸素貯蔵材料は，酸素を選択的かつ可逆に吸収放出する酸化物であり，特に空気分離応用が期待される．ここで紹介する新規鉄系酸化物Ba₅CaFe₄O₁₂は，未知の5重ペロブスカイト型構造をもち，400℃以下で優れた酸素吸放出特性を示す．この新規酸化物は，酸素ガス製造のコストとエネルギー消費量の大幅な削減を実現する可能性を秘める． Translation
Abstract(E)	Oxygen storage materials, exhibiting selective and rapid oxygen intake and release behaviors, have attracted increased attention in oxygen-related technologies, particularly for air separation applications. Here, we present our recent work dealing with a new iron-based oxide, Ba₅CaFe₄O₁₂. This oxide crystallizes in an unprecedented 5-fold perovskite-type structure and demonstrates excellent oxygen intake/release properties in a highly reversible manner at temperatures below 400℃ . Ba₅CaFe₄O₁₂ holds the potential to revolutionize the reducing both costs and energy demand associated with the production of gaseous oxygen through air separation.

About search

How to use the search box

You can enter up to 5 search conditions. The number of search boxes can be increased or decreased with the "+" and "-" buttons on the right.

If you enter multiple words separated by spaces in one search box, the data that "contains all" of the entered words will be searched (AND search).

Example) X (space) Y → "X and Y (including)"

How to use "AND" and "OR" pull-down

If "AND" is specified, the "contains both" data of the phrase entered in the previous and next search boxes will be searched. If you specify "OR", the data that "contains" any of the words entered in the search boxes before and after is searched.

Example) X AND Y → "X and Y (including)" X OR Z → "X or Z (including)"

If AND and OR searches are mixed, OR search has priority.

Example) X AND Y OR Z → X AND (Y OR Z)

If AND search and multiple OR search are mixed, OR search has priority.

Example) W AND X OR Y OR Z → W AND (X OR Y OR Z)

How to use the search filters

Use the "search filters" when you want to narrow down the search results, such as when there are too many search results. If you check each item, the search results will be narrowed down to only the data that includes that item.

The number in "()" after each item is the number of data that includes that item.

Search tips

When searching by author name, enter the first and last name separated by a space, such as "Taro Jidosha".
