High‐Performance Phototransistor Based on a 2D Polybenzimidazole Polymer

open access: yesAdvanced Materials, EarlyView.
A crystalline 2D polybenzimidazole polymer (2DPBI), incorporating a porphyrin‐based π‐system linked via 1,3‐diazole units, is synthesized on the water surface over large areas. The 2DPBI thin‐film exhibits high charge carrier mobility (≈240 cm2 V−1 s−1, measured by terahertz spectroscopy), strong photoresponse, and band‐like transport, enabling ...

Asymmetric Transmission and Diffraction Engineering in Ultrathin media via Coupled Metasurfaces

open access: yesAdvanced Optical Materials, EarlyView.
Grating‐insulator‐grating coupled crosstalking metasurfaces hosted on a silicon nitride membrane platform for asymmetric control of the diffraction pattern and asymmetric transmission. It is shown that exploiting the interferences of higher diffraction orders between the two metasurfaces and engineering the resulting modes enables AT in such ...

Terahertz Spoof Surface Plasmon Polariton Structure for High‐Precision Gas Sensor Technology

open access: yesAdvanced Photonics Research, EarlyView.
This study presents a high‐sensitivity THz sensor based on spoof surface plasmon polaritons, optimized for gas sensing. The multilayer structure enables placement of the sample material in the densest region of the plasmonic surface waves, enhancing interaction with THz waves and significantly improving sensitivity to small refractive index variations ...

Surface Elasticity Based Nonlocal Vibration Analysis of Bidirectional Functionally Graded Tapered Nanobeam

open access: yesAdvanced Theory and Simulations, EarlyView.
This work proposes a surface elasticity‐based nonlocal model for analyzing the vibrations of bi‐directionally graded tapered nanobeam. The results demonstrate that, in absence of surface effect, the increasing value of tapered parameter leads to stiffness‐hardening of the nanobeam. However, the consideration of surface effect changes this trend and the

Neural Plasticity and Hearing‐Speech Development in Children with Auditory Brainstem Implants for Congenital Hearing Loss Due to Severe Inner Ear Malformation

open access: yesAdvanced Science, EarlyView.
Data from a prospective cohort with 112 auditory brainstem implant users are analyzed. Younger age at implantation (<3 years), less severe inner‐ear malformation (common cavity, cochlear aplasia, and hypoplasia), and more intraoperative eABR evoked electrodes (≥60%) are associated with better hearing and speech outcomes.

PP1A Modulates the Efficacy of Lenvatinib Plus ICIs Therapy by Inhibiting Ferroptosis in Hepatocellular Carcinoma

open access: yesAdvanced Science, EarlyView.
PP1A dephosphorylates Keap1 at the S104 site, stabilizing and promoting the nuclear translocation of Nrf2, which upregulates the expression of antioxidant genes and PD‐L1. This leads to suppressed ferroptosis and enhanced immune evasion, thereby improving the efficacy of TKI and ICI combination therapy.
