Fabrication of Multifunctional FeSi Gyroid Lattice Composites via Additive Manufacturing and Polymer Infiltration

Advanced Engineering Materials, Volume 28, Issue 3, 4 February 2026.
A two‐step approach combining laser powder bed fusion of FeSi electrical steel with Bakelite infiltration enables the fabrication of multifunctional gyroid lattice composites. The resulting structures exhibit high strength, magnetic anisotropy, and complete polymer infiltration, demonstrating a simple and scalable route toward lightweight, mechanically

Thermoelectric properties of Co, Ir, and Os-Doped FeSi Alloys: Evidence for Strong Electron-Phonon Coupling

, 2011
The effects of various transition metal dopants on the electrical and thermal transport properties of Fe1-xMxSi alloys (M= Co, Ir, Os) are reported. The maximum thermoelectric figure of merit ZTmax is improved from 0.007 at 60 K for pure FeSi to ZT = 0 ...

Metal–Organic Framework‐Based Materials for Dielectric Energy Storage

Advanced Physics Research, Volume 5, Issue 1, January 2026.
This review explores the structural design of metal–organic frameworks (MOFs) for high‐performance dielectric energy storage applications. By analyzing systems from homogeneous and heterogeneous to stimuli‐responsive and conductive, it fundamentally connects diverse framework topologies to core polarization and charge dynamics.

Spin excitations of the correlated semiconductor FeSi probed by THz radiation

, 2011
By direct measurements of the complex optical conductivity $\sigma(\nu)$ of FeSi we have discovered a broad absorption peak centered at frequency $\nu_{0}(4.2 K) \approx 32 cm^{-1}$ that develops at temperatures below 20 K. This feature is caused by spin-
