A magnetic refrigeration material includes: at least one selected from the group consisting of Y, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm and Tb by a range of 4 to 15 atomic percentages; at least one selected from the group consisting of Fe, Co, Ni, Mn and Cr by a range of 60 to 93 atomic percentages; at least one selected from the group consisting of Si, C, Ge, Al, Ga and In by a range of 2.9 to 23.5 atomic percentages; and at least one selected from the group consisting of Ta, Nb and W by a range of 1.5 atomic percentages or less, wherein the magnetic refrigeration material includes a NaZn13 type crystal structure as a main phase.
摘要:
An adsorbent includes: at least one of an inorganic particle and a metallic particle as a core; at least two kinds of polymers, which cover a surface of the core, with respective different surface tensions; and a convex-concave surface structure formed due to a difference in surface tension between the at least two kinds of polymers.
摘要:
A phosphorus-adsorbing material is produced to include a polymer-based material modified with at least either of a primary and a secondary amine and a metal supported on the polymer-based material, and a phosphorus recovery system is structured by using the phosphorus-adsorbing material.
摘要:
The present embodiment relates to a method for recovering a boron adsorbent, including: preparing water having an electric resistivity of 0.01 MΩ·cm or more and kept at a temperature within a temperature range; and contacting the water with the boron adsorbent to release boron adsorbed at the boron adsorbent.
摘要:
There is provided a water purification material including: a composite metal hydroxide exhibiting a layered structure and including iron ions, calcium ions, and at least one of nitrogen ions and sulfur ions; and at least one of calcium hydroxide and ferric hydroxide, in which a main peak intensity due to at least one of the calcium hydroxide and the ferric hydroxide measured by x-ray crystal structure analysis is equal to or less than half a main peak intensity due to the layered structure of the composite metal hydroxide.
