Correlation between Microstructure and Magnetism in Ball-Milled SmCo₅/?-Fe (5%wt. ?-Fe) Nanocomposite Magnets.

ABSTRACT: Magnetic nanocomposites SmCo₅/?-Fe were synthesized mechanically by high-energy ball milling (HEBM) from SmCo₅ and 5%wt. of ?-Fe powders. The X-ray diffraction analysis reveals the hexagonal 1:5 phase as the main one accompanied by the cubic ?-Fe phase and 2:17 rhombohedral as the secondary phase. The content of each detected phase is modified throughout the synthesis duration. A significant decrease in crystallite size with a simultaneous increase in lattice straining is observed. A simultaneous gradual reduction in particle size is noted from the microstructural analysis. Magnetic properties reveal non-linear modification of magnetic parameters associated with the strength of the exchange coupling induced by various duration times of mechanical synthesis. The highest value of the maximum energy product (BH)_max at room temperature is estimated for samples milled for 1 and 6 h. The intermediate mixed-valence state of Sm ions is confirmed by electronic structure analysis. An increase in the Co magnetic moment versus the milling time is evidenced based on the performed fitting of the Co3s core level lines.

Project description:Transcript profiles of Postia placenta grown on media containing ball-milled aspen or ball-milled pine as the sole carbon source were analyzed. Array design was based on the DoE's Joint Genome Institute's gene models for P. placenta version 1. The research goal is to identtify genes essential for cellulose depolymerization. From a data set of 12,438 unique alleles, each NimbleGen (Madison, WI) array featured 10 unique 60mers per gene, all in triplicate. The dataset was manually annotated to include only the ‘best allelic model’ among CAZY-encoding genes. Total RNA was purified from medium containing ball-milled aspen or ball-milled pine as the sole carbon source. Three biological replicates per medium were used (6 separate arrays). RNA was converted to double-strand cDNA and labeled with the Cy3 fluorophore sample for hybridization to the Postia placenta MAD-698 whole genome expression array by Roche NimbleGen (Iceland). In brief, 10ug of total RNA was incubated with 1X first strand buffer, 10 mM DTT, 0.5mM dNTPs, 100 pM oligo T7 d(T)24 primer, and 200 units of SuperScript II (Invitrogen) for 60 min at 42°C. Second strand cDNA was synthesized by incubation with 1X second strand buffer, 0.2mM dNTPs, 0.07 units per ul DNA ligase (Invitrogen), 0.27 units per ul DNA polymerase I (Invitrogen), 0.013 units per ul RNase H (Invitrogen), at 16°C for 2 hours. Immediately following, 10 units T4 DNA polymerase (Invitrogen) was added for additional 5 minute incubation at 16°C. Double-stranded cDNA was treated with 27ng/ul of RNase A (EpiCenter Technologies) for 10 minutes at 37°C. Treated cDNA was purified using an equal volume of phenol:chloroform:isoamyl alcohol (Ambion), ethanol precipitated, washed with 80% ethanol, and resuspended in 20ul water. One ug of each cDNA sample was amplified and labeled with 1 unit per ul of Klenow Fragment (New England BioLabs) and 1 O.D unit of Cy3 fluorophore (TriLink Biotechnologies, Inc.) for 2 hours at 37°C. Array hybridization was carried out with 6ug of labeled cDNA suspended in NimbleGen hybridization solution for 17 hours at 42°C.
