Artificial intelligence‐assisted design, synthesis and analysis of smart biomaterials

BMEMat, EarlyView.
Smart biomaterials are rapidly emerging as tools for tissue engineering, and artificial intelligence has played essential roles in biomaterial studies. By bridging the literature gap in AI‐based design, synthesis and analysis of smart biomaterials, the current review shares perspectives on how biomaterial scientists can practically incorporate AI for ...

Effect of Background Magnetic Field on Ion Weibel Instability With High‐Intensity Short‐Pulse Lasers

Contributions to Plasma Physics, EarlyView.
ABSTRACT The effect of finite background magnetic field on magnetic field amplification by Weibel instability using high‐intensity short‐pulse lasers is investigated. We consider Weibel instability for counter‐streaming sub‐relativistic plasma flows generated by shooting pure carbon targets with short‐pulse lasers.

Accumulation of Long‐Lived Photogenerated Holes at Copper Yolk‐Shell Heterojunctions via Heterogeneous Contraction and Reduction Strategies for Enhanced Photocatalytic Oxidation

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study explores the structure–activity relationship of Schottky heterojunctions coupled with multi‐level core‐shell structures. Copper‐based yolk‐double shell heterojunction microspheres (Cu/Cu2O@C‐2shell) are constructed using a heterogeneous contraction and reduction strategy to promote the targeted separation of electron–hole pairs, accumulate ...

Optimizing FDTD Solvers for Electromagnetics: A Compiler-Guided Approach with High-Level Tensor Abstractions [PDF]

arXiv
The Finite Difference Time Domain (FDTD) method is a widely used numerical technique for solving Maxwell's equations, particularly in computational electromagnetics and photonics. It enables accurate modeling of wave propagation in complex media and structures but comes with significant computational challenges. Traditional FDTD implementations rely on

All‐Dielectric Metawaveguide Ring Resonators with Deeply Sub‐Diffractive Mode Volumes

Laser &Photonics Reviews, EarlyView.
This article presents the theory, simulation, and experimental realization of whispering gallery mode resonators capable of achieving deeply sub‐diffractive mode volumes, V << 2πR(λ0/2n)2, while preserving high Q factors. Rather than relying on plasmonics to reduce the mode volume, this work relies on nanostructured all‐dielectric metamaterial ...

Boosting Single‐Photon Extraction Efficiency in GaN Through Radiative Mode Conversion

Laser &Photonics Reviews, EarlyView.
Circular Bragg gratings (CBGs) are introduced to efficiently extract single photons over a broad wavelength range emitted from defects in GaN. Single photons propagating along the GaN film or escaping into the substrate are converted into radiative modes by the proposed CBGs, increasing the number of single photons emitted into free space.

Heterogeneous and Monolithic 3D Integrated Full‐Color Micro‐Light‐Emitting Diodes via CMOS‐Compatible Oxide Bonding for µLEDoS

Laser &Photonics Reviews, EarlyView.
A CMOS‐compatible vertically integrated full‐color µLED employing an oxide bonding layer and HM3D technology is first demonstrated for use in µLEDoS applications. The oxide bonding layer provides superior thermal properties compared to the polymer bonding layer, resulting in better device characteristics, such as EQE, color purity, and FWHM, compared ...

Golden Vaterite as a Thermo‐Optical Agent

Laser &Photonics Reviews, EarlyView.
Thermo‐optical therapeutic approaches offer new capabilities in targeted drug delivery, cancer therapy, and tissue engineering applications. The thermo‐optical characteristics of a mesoporous calcium carbonate loaded with gold nanoparticles are explored, thereby forming a metamaterial capsule. Auxiliary optomechanical tools enable efficient prototyping
