  Iron oxide/tantalum oxide core-shell magnetic nanoparticle …

  A new type of metal-oxide-coated magnetic nanoparticles (NPs)--tantalum-oxide-coated magnetic iron oxide (Fe3O4@Ta2O5) NPs--which are used as affinity probes for selectively trapping phosphopeptides from complex samples, is demonstrated in this study. In this approach, phosphopeptide enrichment was …

  Resistors | Audio Note (UK)

  They are similar to the old Shinkoh resistors in that they are non-magnetic, and use a high copper content brass end cap rather than the slightly magnetic iron/nickel end caps found in our standard range of Tantalum resistors.

  Magnetic susceptibility and grain size distribution as …

  2021128 · As iron sands from different localities might have different characteristics (grain-size distribution, mineralogy, magnetic properties), such characteristics might in turn be used for provenance study or for selective mining.

  6.7: Atomic Orbitals and Magnetism - Chemistry LibreTexts

  Weak overlap of 3d orbitals gives narrow d-bands and results in the emergence of magnetic properties as discussed below. Schematic representation of the sizes of different orbitals of Cr and W. In the first transition series, shielding of the 3d orbitals is poor. Therefore the 4s and 4p orbitals are more effective in bonding than the 3d.
