Active Switching of Orbital Angular Momentum of Light Using Metasurfaces Incorporating Vanadium Dioxide

open access: yesNanophotonics, Volume 15, Issue 5, 16 March 2026.
This work presents a novel design strategy for active metasurfaces that actively switches OAM modes. The metasurface integrates VO2 within MIM meta‐atoms. Operating at 1500 nm, the designed platform enables large leaps in topological charge. For instance, the reflected beam can be switched from a topological charge of −1 in the insulating (M1) phase to

Regional and Sex‐Dependent Immune Profiling Across the Colon in A Mouse Model of Ulcerative Colitis

open access: yesThe FASEB Journal, Volume 40, Issue 5, 15 March 2026.
At baseline, males have higher IL‐10, TH17 cytokines, and higher macrophages, neutrophils, and CD8+ cells in the medial and distal colon. Whereas females displayed increasing macrophages, lower TNF‐α, and higher IL‐1β, IL‐17A, and dendritic cells in the cecum and proximal colon.

Reduced vascular leakage correlates with breast carcinoma T regulatory cell infiltration but not with metastatic propensity

open access: yesMolecular Oncology, Volume 20, Issue 3, Page 753-778, March 2026.
A mouse model for vascular normalization and a human breast cancer cohort were studied to understand the relationship between vascular leakage and tumor immune suppression. For this, endothelial and immune cell RNAseq, staining for vascular function, and immune cell profiling were employed.

Joint Control of Radiated and Surface Waves via Space‐Time Coding Metasurfaces

open access: yesAdvanced Functional Materials, Volume 36, Issue 25, 26 March 2026.
A unified space‐time coding metasurface platform enables simultaneous control of radiated and surface‐confined waves across multiple harmonics. Demonstrated functionalities include multi‐frequency beam shaping; surface‐wave excitation, and hybrid multiplexing.

Mechanotransducing Organic Electrochemical Diode for Crosstalk‐Inhibited Artificial Skin

open access: yesAdvanced Functional Materials, Volume 36, Issue 22, 16 March 2026.
An innovative approach is presented to a stretchable mechanotransducing diode that unifies rectification and tactile‐sensing functionality. This approach enables to fabricate the diode that maintains a large rectification ratio (5 × 102) at a high operational frequency (100 Hz).
