Topology Optimization Enables Freeform Matrix Fourier Optics

open access: yesAdvanced Optical Materials, EarlyView.
A topology‐optimized freeform metasurface is designed and fabricated to realize matrix Fourier optics, enabling the diffraction of multiple polarization states into distinct far‐field orders. By combining forward design with gradient‐based inverse optimization, high polarization contrast of up to 98.7% is achieved.

Fully Printed Variable Orifice Flowmeter with Built‐In Temperature Compensation for Application in Mechanical Ventilation

open access: yesAdvanced Sensor Research, EarlyView.
Additive manufacturing, specifically fused deposition modeling, offers an innovative approach to creating 3D‐printed variable orifice flowmeters with integrated temperature compensation. Using carbon‐black TPU, the primary component (a variable orifice) and the secondary element (a diaphragm pressure sensor) are fabricated.

Dual Charge Transfer Mechanisms in Intimately Bonded S‐scheme Heterojunction Photocatalyst with Expeditious Activity toward Environmental Remediation

open access: yesAdvanced Sustainable Systems, EarlyView.
A novel MBOdCN S‐scheme heterojunction photocatalyst is fabricated using pristine Mg‐Bi2O3 and grayish g‐C3N4, where dynamic dual charge migration paths occur to accelerate exciton dissociation. This composite catalyst realizes high degradation efficiency of up to 99.56% of oxytetracycline (OTC) removal under optimized conditions. The material exhibits

The Nuclear Receptor NR1B1/RARα Arrests the Differentiation of Anti‐Tumor Effector Cytotoxic T Cells

open access: yesAdvanced Science, Volume 12, Issue 17, May 8, 2025.
RARα is highly expressed by differentiated effector and exhausted T cells and exerts a negative effect on effector T cell differentiation and the associated trafficking receptor switch. Upregulated RARα levels decrease the nuclear histone acetylase (HAT) activity, and this suppresses the expression of key Teff transcription factor BATF and trafficking ...

Temporal Association Cortex Gates Sound‐Evoked Arousal from NREM Sleep

open access: yesAdvanced Science, Volume 12, Issue 12, March 27, 2025.
It is often wondered why some sounds wake people while others don't. Researchers have discovered that the temporal association cortex plays a key role in this during NREM sleep. Neurons in this region work with the amygdala to decide which sounds are important enough to interrupt sleep, providing a balance between rest and responsiveness.

Transcriptome Landscape of Cancer‐Associated Fibroblasts in Human PDAC

open access: yesAdvanced Science, EarlyView.
AP‐1 family members FOS and JUN regulate the malignant phenotype conversion of normal fibroblasts (NFs) to normal‐like cancer‐associated fibroblasts (nCAFs), while transforming growth factor‐β (TGFβ) and interferon‐γ (IFNγ) signals triggers the interconversion between classic myofibroblastic CAFs (myCAFs) and inflammatory CAFs (iCAFs), respectively ...

Artificial Gold Enzymes Using a Genetically Encoded Thiophenol‐Based Noble‐Metal‐Binding Ligand

open access: yesAngewandte Chemie, Volume 137, Issue 12, March 17, 2025.
A new class of artificial metalloenzymes containing genetically encoded noble‐metal‐binding sites featuring a non‐canonical thiophenol‐based amino acid, which serves as an excellent soft ligand for binding various noble metals, was developed. The corresponding gold(I) enzyme was characterised, confirming gold binding to the thiophenol, and successfully

A Facile Strategy to Restore the Optic Nerve Functionality Using an Injectable Conducting Hydrogel

open access: yesAdvanced Science, EarlyView.
An injectable conductive polymer hydrogel from poly (3,4‐ethylenedioxythiophene) (PEDOT) is developed to facilitate the recovery of electrophysiological function in injured optic nerve. The hydrogel can be injected directly at the injury site and spontaneously gel in place.

Photo‐Biomodulation of the Hippocampus Using Near‐Infrared Laser to Enhance Cognitive Function in Mice

open access: yesAdvanced Science, EarlyView.
Here a transcranial photo‐biomodulation approach is developed using near‐infrared (NIR) laser on hippocampus of mice, revealing significant improvements in learning and memory ability of mice under normal and disease conditions. The improvement results from the high‐density cell‐induced NIR local energy deposition, neuronal activation, and axonogenesis
