Electrostatic Self‐Assembly Induced Nest‐Like MXene Networks on Fabric for Ultra‐Broadband Flexible Absorption

Advanced Science, EarlyView.
In this study, an electrostatically self‐assembled WPU‐MXene@FC flexible fabric constructs a “nest‐like” structure on fibers, building construct MXene multiple loss paths, achieving ultra‐wideband absorption of 25.3–1200 GHz in a thickness of 1.8 mm, while also exhibiting superhydrophobicity, acid and alkali resistance, and bending resistance ...

A Dual‐Channel Synergistic Ultrasensitive Biosensor for Tumor Liquid Biopsy

Advanced Science, EarlyView.
ABSTRACT Liquid biopsy technology, which detects circulating tumor DNA (ctDNA) in cerebrospinal fluid, plays a crucial role in the early diagnosis and precision treatment of gliomas. However, the intrinsically low abundance and rapid clearance of ctDNA pose substantial challenges for conventional analytical techniques, such as droplet digital PCR and ...

Wavefront Line‐Scan Imaging Via a Single‐Pixel Detector

Advanced Science, EarlyView.
We propose and demonstrate a wavefront line‐scan imaging paradigm that integrates 1D spatial light modulation with single‐pixel detection. Benefiting from 1D modulation, not only is the imaging speed improved, but also the storage of modulation patterns is reduced by several orders of magnitude.

Terahertz metasurface based on vanadium dioxide for realizing CNOT logic gate and tunable vortex beams

Results in Physics
Independent phase control of circularly polarized light on a single metasurface is highly desirable for terahertz applications. However, most metasurfaces reported suffer from two critical limitations: the lack of dynamic tunability and narrow ...

Helical Electron Beam Micro‐Bunching by High‐Order Modes in a Micro‐Plasma Waveguide

Advanced Science, EarlyView.
ABSTRACT Electron acceleration by a high‐power Laguerre‐Gaussian pulse in a micro‐plasma waveguide is investigated. When the incident laser travels in the waveguide, electrons on the wall are extracted into the vacuum core and accelerated by the longitudinal field of the waveguide mode.
