Mechanochemical processing of Zn–ferrite powders and their magnetic characterization

Unfolding and Mechanochemical Scission of Supramolecular Polymers Containing a Metal–Ligand Coordination Bond

“…As we mentioned before, we have simulated only 10 ps of the life of the system, whereas 1 μs is the time scale of the experiment. Literature sources provide some more details on the value of the force versus time scale for different types of bonds. , Although there is no Ag–C type of bond mentioned in the reference, we may assume that the trend will be continued, and we could expect the force to be lowered by approximately 15–25%. This value is even closer to the experiment, despite the simplifications used in our model such as the shorter aliphatic chains at the N1 position of the NHC ligands and absence of the solvent.…”

Fuel additives and heat treatment effects on nanocrystalline zinc ferrite phase composition

“…No magnetic anisotropy was observed. The paramagnetic properties for ZnFe 2 O 4 in our experiment (M r ¼5.551 Â 10 À 3 emu g À 1 ) are superior to the nanocrystalline zinc ferrite samples prepared by other techniques [12,[26][27][28][29][30]. Taking into account normal spinel structure of zinc ferrite (ZnFe 2 O 4 ) which has a tetrahedral A-site occupied by Zn 2+ ions and an octahedral B-site occupied by Fe 3+ ions; the coercivity value of 15 Oe suggests that in the as-prepared zinc ferrite cation distribution has partially changed from normal to mixed spinel type.…”

The high impact of a milling atmosphere on steel contamination

“…6 High-energy ball-milling with the steel milling assembly is often used in the mechanosynthesis of ferrites. Zinc ferrite (ZnFe 2 O 4 ) was synthesized by using such a milling assembly from the mixtures of zincite and hematite, [10][11][12][13][14][15][16][17][18][19][20][21][22][23] zinc and hematite, 24 zinc and magnetitite [25][26][27] or zinc, iron and water. 28 Ball-milling with the steel assembly was also used for the investigations of magnetic behavior of mechanically activated ZnFe 2 O 4 29 and Fe-doped zincite.…”
