Infrared Colloidal Quantum Dot Edge Emitting Lasers Integrated on Silicon
Advanced Optical Materials, EarlyView.In this work, the first monolithic integration of Pb‐chalcogenide CQDs in an edge‐emitting DFB laser cavity onto a Si/SiO2 substrate has been demonstrated. The optimizations of SiO2 layer thickness, engineering of the grating duty cycle, and implementing λ/4 phase shift resulted in the achievement of spectrally pure, single‐mode lasing at 1650 nm with ...

Tunable Patterned Blue Phase Liquid Crystals Based on Lithographic Process Technology
Advanced Optical Materials, EarlyView.A patterned blue phase liquid crystal device with electrically driven, localized bistability is demonstrated using a cost‐efficient photolithographic dual‐alignment process. The device switches between a high‐contrast patterned state and a uniform reflective state.

Circularly Polarized Structural Color Pigments Tunable Across the Full Visible Spectrum
Advanced Optical Materials, EarlyView.By infusing black dye into spherical shells of polymerized cholesteric liquid crystal, blue, green and red omnidirectional retroreflectors of circularly polarized structural color are achieved. They can be laid out on arbitrary surfaces without any need for index matching binder to define graphical information for robots and Augmented Reality devices ...

Multipolar Resonances in Electro‐Optic Metasurfaces with Moderate Refractive Index
Advanced Photonics Research, EarlyView.Electro‐optic nanoantennas with moderate refractive indices of 2.3 to 3.0 are numerically shown to sustain strong multipolar resonances, enabling efficient light confinement and EO tuning. Multipolar modes of even parity are most sensitive to variations in the refractive index.

Mettl3‐Mediated m6A Modification Represents a Novel Therapeutic Target for FSGS
Advanced Science, EarlyView.This study explores the roles of Mettl3‐induced N6‐methyladenosine (m6A) modifications in Focal segmental glomerulosclerosis (FSGS). The findings reveal that inhibition of Mettl3 results in podocyte injury by modulating the TJP1CDC42 pathway. Moreover, Administration of N6‐methyladenosine attenuates the FSGS phenotype in WT mice induced by Adriamycin ...

NDST3‐Induced Epigenetic Reprogramming Reverses Neurodegeneration in Parkinson's Disease
Advanced Science, EarlyView.NDST3‐mediated epigenetic reprogramming revitalizes neuronal circuits in the substantia nigra and striatum to halt dopaminergic neuron degeneration and restore motor function in Parkinson's disease models. This strategy promotes neuronal maintenance and functional recovery, highlighting NDST3's therapeutic potential in neurodegenerative disorders ...

PD‐1 Inhibits CD4+ TRM‐Mediated cDC1 Mobilization via Suppressing JAML in Human NSCLC
Advanced Science, EarlyView.CD4+ tissue‐resident memory T cells (TRMs) in non‐small cell lung cancer recruit conventional type 1 dendritic cells via XCL1‐XCR1 signaling, orchestrating antitumor immunity. The costimulatory molecule JAML is essential for this process. PD‐1 blockade restores JAML expression and cDC1 mobilization, while JAML agonists synergize with anti‐PD‐1 therapy,
