Metasurface‐Based Multidimensional Light‐Field Manipulation: From Technologies to Applications

open access: yesAdvanced Science, EarlyView.
Multidimensional metasurfaces enable versatile manipulation of multiple optical degrees of freedom, including phase, amplitude, polarization, wavelength, and orbital angular momentum. This review summarizes their fundamental mechanisms, emerging strategies for multidimensional light‐field control, and key applications in optical computing, imaging ...

Donor‐Cell Senescence Redirects PINK1‐Marked Mitochondrial Cargo From Mitophagy to Microvesicle Transfer Through SUMO3‐Stabilized HSPA9

open access: yesAdvanced Science, EarlyView.
ABSTRACT Extracellular vesicle therapies have been developed for tissue repair, but how donor‐cell senescence reshapes vesicle‐mediated mitochondrial transfer remains unclear. Here, we show that senescent adipose‐derived stem cells (ADSCs) redirect damaged mitochondria into microvesicles (MVs), converting protective vesicles into pro‐degenerative ...

Arhgef1 Deletion Disrupts Early Cortical Neurogenesis via PAK1 Overactivation and Causes Motor Dysfunction in Adulthood

open access: yesAdvanced Science, EarlyView.
ARHGEF1 plays a pivotal role in both embryonic cortical neurogenesis and adult motor function. During early development, it governs genesis of deep‐layer cortical neurons by negatively regulating RAC1/CDC42‐PAK1‐Cofilin signaling. In adulthood, ARHGEF1 is important for the maintenance of neuronal morphology and activity in the motor cortex, ensuring ...

CircFAM65A/CANX Condensates Sequester FAM134B to Inhibit ER‐phagy and Suppress Hepatocellular Carcinoma Progression

open access: yesAdvanced Science, EarlyView.
The novel circRNA circFAM65A suppresses HCC progression. Mechanistically, circFAM65A drives CANX phase separation, which recruits FAM134B into condensates and blocks its interaction with LC3, thereby inhibiting ER‐phagy and HCC progression. Importantly, targeted circFAM65A delivery represents a potential therapeutic strategy for HCC.

Balancing Carrier Cooling in InN/GaN Quantum Wells via Point Defect Engineering

open access: yesAdvanced Electronic Materials, EarlyView.
Nitrogen vacancies in the InN/GaN interface regulate carrier relaxation in polar quantum wells by reconstructing the conduction‐band decay pathway and enhancing nonadiabatic coupling. No deep midgap state is introduced in the neutral single‐vacancy model, enabling faster hot‐electron cooling, improved electron‐hole balance, reduced electron overflow ...

Colossal Modulation of Mechanical Resonance with temperature in single‐Crystalline SrTiO3 Microbridges Integrated on Silicon

open access: yesAdvanced Electronic Materials, EarlyView.
The structural characteristics and resonant mechanical behavior of suspended microbridges comprised of single‐crystalline SrTiO3 that has been grown on silicon are presented. Due to differences in thermal expansion between the SrTiO3 and silicon, we find that the resonant frequencies of the microbridges are not only enhanced, but also hyper‐sensitive ...

Two‐Dimensional Carrier Gas at Diamond and Cubic Boron Nitride (111) Interface: Role of Interfacial Bonding and Defects

open access: yesAdvanced Electronic Materials, EarlyView.
The study identifies four bonding configurations at the (111) diamond/c‐BN interface, where B or N atoms bond with either one or three carbon atoms. C‐B bonds create two‐dimensional (2D) hole gases, while C–N bonds create electron gases. Three‐C‐bonded interfaces show three times higher carrier density than one‐C‐bonded interfaces.

MXene‐Derived Highly Oriented TiN Enables Ta3N5 Photoanodes for Transmission‐Mode Bias‐Free Solar Water Splitting

open access: yesAdvanced Energy Materials, EarlyView.
This work reports 2D MXene‐derived TiN thin films with (111)‐preferred orientation for transparent Ta3N5 photoanodes, demonstrating effective electron transfer behavior. All‐nitride electron‐collection architecture based on MXene‐derived TiN and n‐GaN resolves a long‐standing materials bottleneck between photocarrier transport and light transmission in
