A first-principles study of tunneling magnetoresistance in Fe/MgAl2O4/Fe(001) magnetic tunnel junctions

open access: yes, 2012
We investigated the spin-dependent transport properties of Fe/MgAl2O4/Fe(001) magnetic tunneling junctions (MTJs) on the basis of first-principles calculations of the electronic structures and the ballistic conductance.

The Associations Between Chronic Active Lesions and White Matter Disease: A 7 Tesla Imaging Study

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background The relationship between paramagnetic rim lesions (PRLs) and surrounding normally appearing white matter (NAWM) disease, potentially contributory to the associations seen between PRLs and clinical impairment, is underexplored. Objectives To assess whether PRLs correlate with a greater degree of NAWM injury in early MS.

Isotope shifts and hyperfine structure of the Fe I 372 nm resonance line

open access: yes, 2009
We report measurements of the isotope shifts of the $3d^64s^2 a ^5D_4 - 3d^64s4p z ^5F_5^o$ Fe I resonance line at 372 nm between all four stable isotopes $^{54}$Fe, $^{56}$Fe, $^{57}$Fe, and $^{58}$Fe, as well as the complete hyperfine structure of that

NR4A1 Exerts Pro‐Tumor Role in Glioblastoma via Inducing xCT/GPX4‐Regulated Ferroptosis

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Purpose This study investigates NR4A1's paradoxical roles in glioblastoma (GBM) progression, focusing on its mechanistic link to ferroptosis regulation. We aimed to resolve conflicting reports of NR4A1 as both an oncogene and a tumor suppressor by defining its transcriptional control over xCT/GPX4‐mediated iron homeostasis and its clinical ...

Plasma Glial Fibrillary Acidic Protein Correlates With Brain Metal Burden in Wilson's Disease

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Neuroinflammation driven by extracellular copper contributes to neuronal damage in Wilson's disease (WD). This study investigated the relationship between brain metal burden and peripheral neuroinflammation markers in WD. Methods We conducted a cross‐sectional study involving 89 participants, including patients with WD (n = 63 ...

Sandwich-Like Fe&TiO2@C Nanocomposites Derived from MXene/Fe-MOFs Hybrids for Electromagnetic Absorption

open access: yesNano-Micro Letters, 2020
Sandwich-like laminated Fe&TiO2@C nanocomposites were successfully prepared from the MXene–MOFs hybrids. A broad effective bandwidth of 6.5 GHz at a thickness of only 1.6 mm was achieved. Sandwich-like laminated Fe&TiO2@C nanocomposites were successfully
