Trinuclear Heptamethine Dyes for Shortwave Infrared In Vivo Imaging

Angewandte Chemie, EarlyView.
The reactivity of cyclopentenyl‐bridged polymethine dyes is leveraged to synthesize shortwave infrared (SWIR)‐emissive di‐ and trinuclear polymethine dyes. Chromenylium‐ and flavylium‐based trinuclear dyes demonstrate increased nucleophilic stability, minimal aggregation in micelle formulations, and notable lymph node accumulation.

Integrated Ultrasound Device for Precision Bladder Volume Monitoring via Acoustic Focusing and Machine Learning

Advanced Science, EarlyView.
We present a conformable wearable ultrasound patch for noninvasive bladder volume monitoring. A flexible PZT array combined with a concave acoustic lens concentrates acoustic energy and improves depth selectivity through the anterior pelvic wall.

Recent Advances in Laser‐Induced Graphene‐Based Gas Sensors: From Sensing Mechanisms to Biomedical Applications

Advanced Science, EarlyView.
Laser‐induced graphene (LIG) provides a scalable, laser‐direct‐written route to porous graphene architecture with tunable chemistry and defect density. Through heterojunction engineering, catalytic functionalization, and intrinsic self‐heating, LIG achieves highly sensitive and selective detection of NOX, NH3, H2, and humidity, supporting next ...

Temperature measurement of overlapped fiber Bragg grating sensors in a series fiber sensor network

Results in Optics
Fiber Bragg Gratings (FBGs) in a sensor network have been widely used for structural health and process monitoring. The number of FBGs with distinct wavelength that can be used in such a sensor network is limited by the bandwidth of the laser used. FBGs,

Tumor‐Derived Exosomal TAGLN2 Promotes Metastasis by Inducing Vascular Permeability and Angiogenesis via the NRP1/SEMA4D/YAP Axis

Advanced Science, EarlyView.
Gastric cancer‐derived exosomal TAGLN2 is identified as a key mediator of vascular reprogramming, with significantly elevated levels detected in patient serum. Independent of canonical SEMA4D signaling, it nucleates a cytoplasmic TAGLN2/NRP1/SEMA4D ternary complex that dually activates YAP, promoting angiogenesis, vascular dysfunction, and metastasis ...

Temperature-Insensitive Second-Order Microring Resonator for Dense Wavelength Division Multiplexing (DWDM)

IEEE Photonics Journal
To achieve temperature-insensitive passband responses of microring resonator (MRR) for DWDM signal processing, we design and fabricate a wavelength division multiplexer with four channels based on 2nd-order slot MRR with PMMA cladding layer. Four filters

Realization of a Bilayer Elastic Topological Insulator

Advanced Science, EarlyView.
Bilayer elastic wave topological insulators are experimentally realized, introducing the layer degree of freedom to access four topological phases. This enables diverse domain walls and transmission behaviors, including interlayer conversion and beam splitting.
