Modulating D33 Coefficients Through In Situ AgF and Ag2O Growth in PVDF Composites for High‐Performance Piezoelectric Nanogenerators

Advanced Materials Technologies, EarlyView.
In situ, nanoparticle doping enhances the piezoelectric coefficient (**d₃₃**) of PVDF to ≈12 pC/N, while in situ growth of AgF and Ag₂O dopants increases β‐phase concentration. The nanogenerator achieves a 35 V open‐circuit voltage and 1.6 µA short‐circuit current, powering 10 blue LEDs and charging a 50 nF capacitor within 10 s.

Frequency‐Selective Terahertz Wave Amplification by a Time Boundary in Huygens' Metasurface

Advanced Optical Materials, EarlyView.
In a free‐standing all‐dielectric Huygens' metasurface, ultrafast pulsed laser excitation is used to establish the time boundary for a coherent modulation to the electric and magnetic polarizability in the adiabatic limit. Amplification of THz waves at frequencies that can be continuously tuned have been achieved, showing an effective energy gain up to

Enabling low Threshold Laser Through an Asymmetric Tetramer Metasurface Harnessing Polarization‐Independent Quasi‐BICs

Advanced Optical Materials, EarlyView.
Light impinging from the left on a metasurface composed by active material. The metasurface shows asymmetric configuration through the non‐uniform presence of holes. The forming quasi‐BICs modes are exploited for lasing purposes. Abstract It is proposed and numerically demonstrated a novel strategy to achieve lasing generation from a dual‐band symmetry‐

GR-RMHD Simulations of Super-Eddington Accretion Flows onto a Neutron Star with Dipole and Quadrupole Magnetic Fields

The Astrophysical Journal
Although ultraluminous X-ray pulsars (ULXPs) are believed to be powered by super-Eddington accretion onto a magnetized neutron star (NS), the detailed structures of the inflow–outflow and magnetic fields are still not well understood.

Selective Directional Enhancement in Gold/Perovskite Quantum Dot Metasurfaces

Advanced Optical Materials, EarlyView.
A thin gold layer can selectively enhance the directional radiation of a perovskite quantum dot (QD)1D metasurface by incorporating hybrid plasmonic excitation and redistributing diffraction orders from substrate to cover. The use of template‐assisted self‐assembly techniques enables breakthrough tunability in radiative properties over large areas ...
