Impact-generated magnetite in Chang’e-5 soil as a potential recorder of lunar magnetism

Communications Earth & Environment
Magnetite is a principal paleomagnetic recorder on Earth, but lunar magnetism is thought to be dominated by metallic iron and Fe-Ni alloys, with magnetite rare and typically sub-micrometer within troilite.

On magnetite-bearing pegmatites in SE Sottunga, Åland Islands [PDF]

Bulletin of the Geological Society of Finland, 1969
Magnetite-bearing pegmatites of SE Sottunga, Åland Islands, are described. The pegmatites, which are probably granitization products, have derived their magnetite material from the iron-silicates of the host rocks, especially from the biotite.

Remote Magnetomechanical Neuromodulation Uncovers Therapeutic Mechanisms for Alleviating Parkinsonian Symptoms in Freely Moving Mice

Advanced Science, EarlyView.
Magnetomechanical neuromodulation using magnetic nanodiscs enables remote activation of neurons. In a hemiparkinsonian mouse model, alternating magnetic fields actuate the nanodiscs to generate torque that opens mechanosensitive ion channels within the subthalamic nucleus, thereby modulating basal ganglia motor circuitry.

Nanomaterials for Allergy Diagnosis and Treatment: Advances, Opportunities and Translational Challenges

Advanced Science, EarlyView.
Nanomaterials offer dual applications in allergy management. For diagnosis, nanomaterials enhance analytical sensitivity and improve detection in specific IgE and functional assays such as the basophil activation test (BAT). For allergen‐specific immunotherapy, nanomaterials enable allergen masking and controlled release, and effectively modulate the ...

Surface‐Spin‐Induced Magnetic Loss Enhancement in Ultralight Electromagnetic Absorbers

Advanced Science, EarlyView.
Fe3O4 nanoparticles with different hollow rates were synthesized to demonstrate the key role of surface moment in magnetic loss process. Using the same volume filling ratio, the 54.1% hollow Fe3O4 absorber represents about 20% enhancement in the imaginary part (μ'') than solid particles due to the coexisting magnetic resonance of inside and outside ...
