Room Temperature Blocked Magnetic Nanoparticles Based on Ferrite Promoted by a Three-Step Thermal Decomposition Process

Exchange coupled nanoparticles that combine hard and soft magnetic phases are very promising to enhance the effective magnetic anisotropy while preserving sizes below 20 nm. However, the core-shell structure is usually insufficient to produce rare earth-free ferro(i)magnetic blocked nanoparticles at room temperature. We report on onion-type magnetic nanoparticles prepared by a three-step seed mediated growth based on the thermal decomposition method. The core@shell@shell structure consists of a core and an external shell of Fe3-?O4 separated by an intermediate Co-doped ferrite shell. The double exchange coupling at both core@shell and shell@shell interfaces results in such an increased of the magnetic anisotropy energy, that onion-type nanoparticles of 16 nm mainly based on iron oxide are blocked at room temperature. We envision that these results are very appealing for potential applications based on permanent magnets.

FATTY ACID METAL SALT FOR FORMING ULTRAFINE METAL PARTICLE

A fatty acid metal salt used for forming ultrafine metal particles satisfying at least one of that: (i) the water content is 200 ppm or less; (ii) the volume-cumulative particle diameter D90 is 80 μm or smaller as measured by the particle size distribution measuring method of the laser diffraction/scattering type; or (iii) a metal of an atomic weight of 50 to 200 is contained, and the amount of the unreacted substance or the by-product is 4.0 mol% or less when the fatty acid metal salt is formed. The fatty acid metal salt can be favorably used for forming ultrafine metal particles in a resin, or for forming a resin composition, a coating, a dispersion solution or a molded article containing the ultrafine metal particles.

Catalytic oxidative cleavage of terminal olefins by chromium(III) stearate

A new synthetic methodology for the preparation of carbonyl compounds from the oxidative cleavage of terminal olefins has been developed. With the use of TBHP in combination with chromium(III) stearate, selective oxidation of double bonds conjugated with aromatic ring or carbonyl group could be achieved at ambient temperature in moderate to excellent yield. The oxidative cleavage of electron rich α-methylstyrene derivatives proceeded in good to excellent yield whereas lower yields were observed in α-methylstyrene derivatives containing an electron withdrawing group. This developed oxidation reaction was believed to undergo via free radical process and high valent chromium oxo species.
