Ultra‐Fast and Energy‐Efficient PZT Optical Tunable Delay Lines for Programmable Photonic Systems

open access: yesLaser &Photonics Reviews, EarlyView.
Thin‐film PZT enables optical tunable delay lines that simultaneously offer sub‐nanosecond switching, low propagation loss, and zero‐static‐power programmability. A five‐bit on‐chip delay line provides a maximum delay of 387.5 ps with a resolution of 12.5 ps, while reconfigurable MZI splitting ratios further enable non‐volatile optical arbitrary ...

Heterogeneous Integration of Multi‐Band Mode‐Locked and Single‐Mode Lasers on an Extended Commercial SiN Platform

open access: yesLaser &Photonics Reviews, EarlyView.
Micro‐transfer printing enables GaAs and InP gain materials to be integrated on a commercial silicon nitride photonic platform. The resulting chip supports O‐ and C‐band comb and single‐mode lasers, demonstrating a scalable route toward multi‐material, multi‐wavelength, and multifunctional integrated light sources.

Recent Advances in Cryogel Applications for Musculoskeletal Regeneration

open access: yesMedicinal Research Reviews, EarlyView.
ABSTRACT Hydrogels have been widely used in tissue engineering due to their high‐water content and biocompatibility, yet their densely cross‐linked microstructure inherently limits cell infiltration, mass transport, and mechanical support. Cryogels, formed through partial freezing and crosslinking under subzero conditions, provide unique 3D macroporous

An Adaptive Metasurface for Adjustable Magnetic Resonance Imaging Enhancement at 3 T and 7 T: A Feasibility Study

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Ultra‐high field (≥ 7 T) and 3 T MRI suffer from B1+ inhomogeneity and signal loss. Conventional metasurfaces that mitigate B1+ inhomogeneity and improve image SNR are “fixed” in nature and designed for a single Larmor frequency. This study demonstrates the feasibility of an adaptive metasurface utilizing voltage‐controlled capacitors ...

Responsive nanoheterojunctions for built‐in electric field‐promoted cascade tumor targeting and cuproptosis‐based therapy

open access: yesResponsive Materials, EarlyView.
Nanoheterojunctions have been synthesized as responsive biomaterials for cascade targeting of tumor cells and mitochondria, ROS‐mediated apoptosis and Cu‐promoted cuproptosis. And drug‐device‐field integration as an advanced paradigm of tumor treatment was employed for photo‐triggered tumor cell elimination in vitro and lesion eradication in vivo ...
