Multi‐dimensional, multi‐interfacial, and multi‐path synergy enables broadband absorption, corrosion resistance, Joule heating, and thermal performances in hierarchical carbon/Ni nanoparticles‐carbon nanocoils foams

open access: yesInfoMat, EarlyView.
Owing to the severe electromagnetic wave (EMW) pollution and the increasingly intricate operating environments, an excellent EMW absorber with multiple functions has become imperative. Herein, 3D/0D‐1D hierarchical carbon/Ni nanoparticles‐carbon noncoils (CNCs) composite foams with multi‐dimensional, multi‐interfacial and multi‐path structures can be ...

Topological Engineering of High‐Order Exceptional Points Through Transformation Optics

open access: yesLaser &Photonics Reviews, EarlyView.
A novel framework leveraging transformation optics is introduced for engineering high‐order exceptional points (EPs) in nanophotonic systems. By linking these spectral singularities to physically accessible parameters, this approach enables the design of complex EPs, including third and fourth‐order EPs in coupled nanowire systems.

A Linear‐to‐Linear Cross‐Polarization Conversion q‐BIC Metasurface for Transmission Mode Mid‐Infrared Spectral Filtering

open access: yesLaser &Photonics Reviews, EarlyView.
Manipulating the ultranarrow linewidth spectral features of quasi bound states in the continuum is challenging. A metasurface supporting linear‐to‐linear cross‐polarization coupling efficiency surpassing 25% is proposed to address the issue. Less than 100 nm linewidth is achieved, enabling the device to be applied to wavelength‐selective polarization ...

Tailoring SHG Efficiency via t‐Te Nanocrystals in Tellurite Glasses by Femtosecond Laser Micromachining

open access: yesLaser &Photonics Reviews, EarlyView.
Femtosecond laser irradiation at the glass surface induces symmetry breaking and crystallization of triclínic t‐Te nanophases, enabling intense second‐harmonic generation (SHG). The illustration depicts the fs‐pulse interaction, structural rearrangement, and nonlinear activation from amorphous tellurite glass to crystalline regions.

Enhancing Crystallinity of Electrospun Polylactic Acid Fibers: Insights into Formation Mechanisms and Property Modulation–A Review

open access: yesMacromolecular Materials and Engineering, EarlyView.
Controlled processing, nucleating agents, and monitored post‐treatments improve electrospun PLA nanofiber crystallinity. Additionally, stereocomplexation of PLLA and PDLA further enhances this property. Together, these strategies enable scalable, sustainable fabrication of high‐performance PLA nanofibers, expanding their applicability across industrial,
