Observation of Localized Resonant Phonon Polaritons in Biaxial α‐MoO3 Nanoparticles

Advanced Science, EarlyView.
Biaxial α‐MoO3 nanoparticles exhibit tunable, high‐Q mid‐infrared resonances driven by localized phonon polaritons. Combining a novel synthesis method, hyperspectral near‐field imaging and a unified theoretical analysis, this work reveals eigenmodes and resonance conditions in biaxial particles.

Enhanced Spectral Tunability by Sub‐10 nm Nanogaps in Graphene‐Metal Hybrid Metasurfaces

Advanced Science, EarlyView.
A tunable mid‐infrared metasurface integrating graphene and metal antenna arrays with sub‐10 nm nanogaps is presented, overcoming the ≈20 nm limit of conventional fabrication. The enhanced spectral tuning range and modulation depth are enabled by combining electron‐beam lithography, thin metal deposition, and directional ion milling to precisely define

Impact of Controlled Magneto‐Structural Coupling in MnCoGe‐Based Compounds on the Design of Multifunctional Materials for Technological Advances

Advanced Science, EarlyView.
In this work, the authors systematically investigate how Ni substitution regulates the magneto‐structural coupling and their functional consequences in the MnCoGe‐based compounds. Geometric nonlinear theory analysis reveals that Ni modification change of magneto‐structural transition can alleviate the lattice incompatibility, thereby broadening the ...

Reversing Hydrogen‐Related Loss in α‐Ta Thin Films for Quantum Device Fabrication

Advanced Science, EarlyView.
α‐Tantalum is one of the best materials for superconducting quantum computers because of its stable, low microwave‐loss oxide. However, excessive amounts of hydrogen can enter the material during fabrication. This study shows that hydrogen degrades quantum device performance, while annealing the device in ultra‐high vacuum removes hydrogen and fully ...

Discovery and Follow-up of a Quasiperiodically Nulling and Subpulse Drifting Pulsar with the Murchison Widefield Array

The Astrophysical Journal
The phenomenon of pulsar nulling, where pulsars temporarily and stochastically cease their radio emission, is thought to be indicative of a “dying” pulsar, where radio emission ceases entirely.
