Holistic numerical simulation of a quenching process on a real-size multifilamentary superconducting coil

Nature Communications
Superconductors play a crucial role in the advancement of high-field electromagnets. Unfortunately, their performance can be compromised by thermomagnetic instabilities, wherein the interplay of rapid magnetic and slow heat diffusion can result in ...

La2O3‐Doped ZrO2 Tapes for Enhanced Thermomagnetic Conversion in CoFeB Heterostructures

Journal of the American Ceramic Society, Volume 109, Issue 6, June 2026.
ABSTRACT This work investigates the thermomagnetic response of La2O3‐doped ZrO2/CoFeB heterostructures for energy harvesting applications. La2O3‐doped ZrO2 ceramic tapes were fabricated via tape casting, followed by the deposition of CoFeB ferromagnetic thin films using magnetron sputtering.

Dual‐Function Lipid‐Based Nanovector Strategy for Glioblastoma Immunotherapy: STING Activation and M1 Microglia Polarization

Drug Development Research, Volume 87, Issue 3, May 2026.
ABSTRACT Glioblastoma (GBM) remains one of the most lethal brain malignancies because of its highly immunosuppressive tumor microenvironment and the limited penetration of therapeutics across the blood‐brain barrier (BBB). Although recent studies have separately explored STING agonism, microglial reprogramming, and nanocarrier‐based drug delivery, an ...

Magnetic Properties of Fe-Nb-B-RE (RE = Tb, Tb/Y, Tb/Nd) Amorphous and Annealed Melt-Spun Ribbons

Crystals
This paper discusses the magnetic properties of Fe-Nb-B-RE (RE = Tb, Tb/Y, Tb/Nd) melt-spun ribbons. Samples were obtained using a typical melt-spinning technique. The dominant amorphous state was confirmed by XRD and thermomagnetic measurements.

Finite Size‐Effects in Martensite Microstructure of Magnetic Shape Memory Films

Small, Volume 22, Issue 19, 1 April 2026.
Magnetic shape memory alloys are a promising multifunctional material system for integration into microsystems. Their multifunctionality arises from the coexistence of ferroelasticity and ferromagnetism. While size‐effects in ferromagnetic microstructure are well understood, corresponding experiments on the ferroelastic microstructure are sparse.

Late Eocene to Early Oligocene (36–26 Ma) Rock Magnetism and Magnetostratigraphy of IODP Site U1553, Southwestern Pacific: Defying the Challenges of Carbonate Dilution and Reductive Diagenesis

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 4, April 2026.
Abstract The late Eocene to early Oligocene is an intriguing Paleogene period in which the Earth climate state changed from Warmhouse to Coolhouse. Accurate age models are essential for investigating these climate transitions. The southwestern Pacific International Ocean Discovery Program (IODP) Site U1553, with its almost complete succession of the ...
