An Atomic‐Scale View at γ’‐Fe4N as Hydrogen Barrier Material

Advanced Materials Interfaces, EarlyView.
This study demonstrates the efficacy of γ’‐Fe4N nitride layers, formed via gas nitriding, as hydrogen permeation barriers. Advanced characterization, hydrogen permeation analysis, and DFT calculations reveal a 20 fold reduction in hydrogen diffusion at room temperature.

Solution‐Processable Polymer Nanocomposites for Electromagnetic Interference Shielding

Advanced Materials Interfaces, EarlyView.
This review introduces scalable strategies for fabricating solution‐processable polymer nanocomposites with improved electromagnetic interference (EMI) shielding performance. It compares three fabrication methods, including solution blending, in situ polymerization, and Pickering emulsion polymerization, and highlights their respective advantages in ...

How to Manufacture Photonic Metamaterials

Advanced Materials Technologies, EarlyView.
Metamaterials boast applications such as invisibility and “hyperlenses” with resolution beyond the diffraction limit, but these applications haven’t been exploited in earnest and the market for them hasn’t grown much likely because facile and economical methods for fabricating them without defect has not emerged.

Physical signatures of fermion-coupled axion dark matter

Journal of High Energy Physics
In the presence of axion dark matter, fermion spins experience an “axion wind” torque and an “axioelectric” force. We investigate new experimental probes of these effects and find that magnetized analogs of multilayer dielectric haloscopes can explore ...

High‐Transmission Mid‐Infrared Bandpass Filters using Hybrid Metal‐Dielectric Metasurfaces for CO2 Sensing

Advanced Optical Materials, Volume 13, Issue 8, March 13, 2025.
This article presents a hybrid metal‐dielectric metasurface in transmission mode for mid‐infrared (MIR) spectroscopy. Composed of germanium on aluminium cylinders atop a calcium fluoride substrate, the metasurface achieves 80% transmission efficiency at λ = 2.6 µm with a narrow full‐width‐half‐maximum of 0.4 µm.

Fabrication and Optical Characterization of CMOS‐Compatible Honeycomb‐Like Large‐Scale Lattices of Near‐Field Coupled Plasmonic TiN Nanotriangles

Advanced Optical Materials, EarlyView.
Honeycomb‐like plasmonic titanium nitride nanotriangle arrays are fabricated in a complementary metal‐oxide‐semiconductor pilot line. Experimental and simulated reflectances as a function of energy and in‐plane momentum match a dispersion relation based on nearest‐neighbor dipole coupling, this indicates Diract points at the K point.

Optical Self‐Tuning of Ferroelectric Metasurfaces Infiltrated with Nematic Liquid Crystals via Photovoltaic Effect

Advanced Optical Materials, EarlyView.
A novel scheme is introduced to achieve optical self‐tuning in ferroelectric lithium niobate (LN) metasurfaces equipped with a thin film of liquid crystals (LCs). The resonant optical field distributions inside the meta‐atoms can induce a photovoltaic (PV) field, which reorients the surrounding LCs.

Toward Enhancing Chiro‐Optical and Magneto‐Optical Properties of Magnetic Nanocrystals by Surface Plasmons

Advanced Optical Materials, EarlyView.
Here, recent progress is highlighted in colloidal magnetoplasmonic hybrid nanomaterials, with a focus on chiral plasmonics. Metal nanocrystals with intrinsic chiroptical features can lead to a combination of chiral plasmonics and magneto‐optics effects when interacting with the magnetic counterpart, offering a foundation for systematically designing ...

The magnetic field of Mars estimated from the data of plasma measurements by Soviet artificial satellites of Mars [PDF]

The dimensions of the obstacle forming the shock wave of Mars are estimated by use of electron trap data from Mars 2, 3, and 5. The mean altitude of the obstacle at the subsolar point can be convincingly explained if the obstacle is the magnetosphere of ...

Mechanically Tunable Optical Response in Silicon Nanosphere Metasurface Fabricated via Bottom‐Up Process

Advanced Optical Materials, EarlyView.
A large area mechano‐tunable square lattice array of silicon nanospheres is fabricated by a bottom‐up process, and the capability to tune the lattice resonances by external strain is demonstrated. Spectrally overlapping the electric and magnetic dipole lattice resonances by mechanical strain induces the lattice Kerker effect and strongly suppresses the
