Achieving Ultra‐Low Megahertz Loss in Nanocrystalline Magnetic Powder Cores via Alloy Design and a Self‐Healing Organic–Inorganic‐Derived Hybrid Insulating Layer

open access: yesAdvanced Chemical Engineering, Volume 1, Issue 2, December 2026.
A novel self‐healing FePO4/B2O3/epoxy hybrid insulating layer is designed for high‐frequency Fe‐based nanocrystalline magnetic powder cores. During 530°C annealing, the low‐melting‐point B2O3 softens, flowing into micro‐cracks formed within the brittle FePO4 framework during cold pressing. This in situ gap‐filling mechanism effectively suppresses inter‐

Methodology of magnetorheological sport damper demagnetization

open access: yes, 2015
This thesis is dedicated to discovering the most efficient methods of demagnetization. At the beginning, basics of magnetorheological (MR) dampers are explained. Available literature is studied to propose appropriate methods of demagnetization.

Materials‐Driven Additive Manufacturing for Electrical Machines: Qualification‐Oriented Design Beyond Geometric Freedom

open access: yesAdvanced Engineering Materials, Volume 28, Issue 21, 4 November 2026.
This perspective reframes additive manufacturing for electrical machines as a qualification‐limited materials and architecture design problem. It links process–structure–property–performance relationships to magnetic, conducting, dielectric, and thermal property windows, highlighting where AM can enable segmented magnetic circuits, permanent magnet ...

Ultra‐Weak Photon Emission as a By‐Product of Mitochondrial Oxidative Metabolism: Mechanisms, Limits, and Implications

open access: yesNanophotonics, Volume 15, Issue 20, 27 October 2026.
Mitochondrial oxidative metabolism generates ROS. Downstream chemiexcitation triplet carbonyls, singlet oxygen; produces ultra‐weak photon emission (UPE). Energetic bounds restrict well‐coupled respiration to extremely weak, red/NIR‐biased emission. Stronger visible UPE indicates elevated oxidative flux, linking measured photon counts to redox state ...

Quantifying Non‐Maxwellian Properties of Ion Populations During Reconnection at Earth's Magnetopause

open access: yesGeophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract We investigate ion velocity‐space features within the exhaust of magnetopause reconnection using a global hybrid‐Vlasov simulation. The Hermite transform and Gaussian Mixture Model (GMM) are applied to quantify the complexity of velocity‐space structures that arise during the mixing of magnetospheric and magnetosheath ion populations.

Onset of Thrusting at ca. 23 Ma in East Kunlun Mountains, Northern Tibet, Recorded by Syntectonic Strata

open access: yesGeophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract The timing of Cenozoic deformation in the East Kunlun Mountains, northern Tibet, is crucial for understanding plateau growth but remains disputed due to the scarcity of direct chronological constraints on specific tectonic structures. Here, we present a high‐density‐sampling magnetostratigraphic record from the Xiaohongshan section, interior ...

Standard Parameter Generation Strategy for Power Transformer Residual Flux Detection and Verification Platform

open access: yesEnergies
Residual magnetism in power transformer cores can cause severe inrush currents, threatening grid safety. The accuracy of residual magnetism testers depends on reference values from calibration platforms, yet current calibration platforms suffer from ...
