Versatile Control of Spectral Emissivity in Mid‐Infrared Metasurfaces via Silicon Microstructuring

open access: yesAdvanced Optical Materials, Volume 14, Issue 10, 13 March 2026.
A family of metasurfaces is obtained very simply, solely through the structuration of a single‐crystal silicon surface, without any other material involved. Based on the infrared plasmonic behavior of highly doped silicon, further control of surface topography by micro‐ and nano‐structuration is found to enable an avenue of options toward tailoring its

Smart SPR Biosensors: Machine Learning‐Augmented Dual‐Channel PCF Technology

open access: yesAdvanced Photonics Research, Volume 7, Issue 3, March 2026.
The biosensor shows outstanding performance over a wide refractive index range (1.33–1.45), with wavelength sensitivity of 32 000 nm/RIU, amplitude sensitivity of 2338 RIU−1, and spectral resolution of 3.13 × 10−6 RIU. We present a modern dual‐channel surface plasmon resonance (SPR) biosensor that combines advanced photonic crystal fiber (PCF) design ...

Real‐Time In Vivo Cellular‐Level Imaging During Puncture

open access: yesAdvanced Science, Volume 13, Issue 14, 9 March 2026.
We present an artificial‐intelligence‐empowered integrative‐light‐field microendoscopy (AIM) needle that delivers real‐time in vivo, diffraction‐limited cellular‐level imaging during puncture and visualizes layered microstructures along the needle path. As a microscopic complement to CT/ultrasound, it improves sampling localization and adds preliminary

Degeneracy Sensing Light Detection and Ranging‐Inertial Simultaneous Localization and Mapping with Dual‐Layer Resistant Odometry and Scan‐Context Loop‐Closure Detection Backend in Diverse Environments

open access: yesAdvanced Intelligent Systems, Volume 8, Issue 3, March 2026.
This paper presents a degeneracy‐aware light detection and ranging (LiDAR)‐inertial framework that enhances LiDAR simultaneous localization and mapping performance in challenging environments. The proposed system integrates a dual‐layer robust odometry frontend with a Scan‐Context‐based loop‐closure detection backend.

Discovery and Initial Investigation of a New Low Surface Brightness Planetary Nebula Candidate at High Galactic Latitude

open access: yesAstronomische Nachrichten, Volume 347, Issue 3, March 2026.
ABSTRACT Planetary nebulae represent a late evolutionary phase of low‐ to intermediate‐mass stars. In this article, we present the serendipitous discovery of a previously unknown, faint potential Galactic planetary nebula (PN) in the constellation Camelopardalis, identified during a survey‐inspection, aiming at the detection of dwarf companions of the ...
