Purpose: The development of colon cancer markers that can detect liver metastases early and predict which patients are at risk to develop liver metastases would have a major impact on this disease. We have previously identified G. Brunagel, et al., Cancer Research, 62: 2437–2442, 2002, nuclear matrix proteins (NMPs), which are associated with colon cancer. The objective of this study is to iden...

Elastic and anelastic properties of a member of the BiFeO3-CaFeO2.5 perovskite solid solution (BCFO), which is known to have multiple instabilities, have been investigated by resonant ultrasound spectroscopy. This phase, with 64% Bi and 36% Ca on the A site, is antiferromagnetic (TN ∼650 K) and has an ordered arrangement of oxygen vacancies with tetragonal lattice geometry. The inverse mechanic...

The surface of BiFeO3 single crystals has been characterized at the local level using several AFM-based techniques. We have observed the presence of two different epilayers showing electrical and mechanical properties different from those of the bulk: a ferroelectrically “dead” outer skin of 5 nm sitting upon a subsurface layer that displays an extremely fine pattern of hierarchical self-ordere...

The thin-film heterostructures or nanocomposites exhibit vastly different properties from those observed in bulk systems. Herein, a nanocomposite of reduced graphene oxide (RGO) and BiFeO3 (BFO), the remnant ferroelectric polarization is found to follow nonmonotonic magnetic field dependence at room temperature as applied swept across 0–20 kOe on pristine sample. Bulk BiFeO3, contrast, exhibits...

We investigate the interfacial chemistry of secondary Fe₂O₃ phases formed in a BiFeO₃ (BFO) layer in BFO/ La0.67Sr0.33MnO₃ (LSMO)/SrTiO₃ (STO) heterostructures. A combination of high-resolution spherical aberration corrected scanning TEM and spectroscopy results, reveals that specific chemical and crystallographic similarities between Fe₂O₃ and BFO, enable the BFO layer to form a facile host fo...

Fast cooling after sintering or annealing of BiFeO3-BaTiO3 mixed-oxide ceramics yields core-shell structures that give excellent functional properties, but their precise phase assemblage and nanostructure remains an open question. By comparing conventional electron energy loss spectroscopy (EELS) with scanning precession diffraction (SPED) mapping using a direct detector, we correlate chemical ...
