Commercial barium hydroxide [Ba(OH)₂•8H₂O], cerium nitrate [Ce(NO₃)₃•6H₂O] or yttrium acetate hydrate [Y(CH₃COO)₃•xH₂O], and Hhfa (Hhfa = 1,1,1,5,5,5-hexafluoroacetylacetone) were purchased from STREM Chemicals Inc. Bischheim (France), while diglyme and tetraglyme (diglyme = bis(2-methoxyethyl)ether and tetraglyme = 2,5,8,11,14-pentaoxapentadecane) were purchased from Sigma-Aldrich (Merck KGaA, Germany). All chemicals were used without any further purification.
The Ba(hfa)₂tetraglyme, Ce(hfa)₃diglyme and Y(hfa)₃diglyme compounds were synthesized by reacting the barium hydroxide, cerium nitrate hydrate, or yttrium acetate hydrate, respectively, with the ligands Hhfa and polyether, such as tetraglyme (for Ba) and diglyme (for Ce and Y).

Flame-Spray Synthesis of SmCoO Nanoparticles

Check if the same lab product or an alternative is used in the 5 most similar protocols

Sm_xCo_yO_z, (nominally SmCo₅O₉), nanoparticles were custom synthesized by Nanocerox (Ann Arbor, MI) using flame spray pyrolysis of controlled ratios of Sm and Co salts dissolved in organic solvents. Particle size was predominantly 20–50 nm, with some particles in the 50–100 nm range. Absolute ethanol was used as received; Tetraglyme; Ca granules, redistilled, 16 mesh, 99.5%; and 1 mm thick graphite electrodes were from Sigma-Aldrich; Alfa Aesar; and Ohio Carbon Blank; respectively. For characterization it was desirable to remove the calcium oxide from the sintered magnet. The calcium was removed from the monolithic sintered magnets by soaking them for 30 minutes in water saturated with bubbling argon gas.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
