Millisecond‐Switching Dual‐Band/Dual‐Polarization Ka‐Band Wavefront Control Enabled by a Complementary Liquid‐Crystal Metasurface

Advanced Materials Technologies, EarlyView.
An LCD‐compatible complementary liquid‐crystal metasurface delivers dual‐band, dual‐polarized Ka‐band wavefront control with millisecond switching via a 10‐µm LC gap. Interlaced patch/slot pairs enable independent phase tuning at 28 and 38 GHz, while strategic 45° slot rotation suppresses parasitic resonances. Measurements on a 160 × 160‐cell prototype

An Ultra‐Wideband Metasurface Perfect Absorber Based on Hybrid Absorption Modes

Advanced Photonics Research, EarlyView.
A Ge2Sb2Te5 metasurface absorber enables polarization‐independent, ultrabroadband (UV–NIR) light absorption with high angular tolerance. Its performance stems from overlapping electric and magnetic dipole resonances in a symmetric structure, achieving 94% average absorption and maintaining 83% even at 70° incidence, promising for integrated ...

Waveguide Photoactuators: Materials, Fabrication, and Applications

Advanced Robotics Research, EarlyView.
Waveguide photoactuators convert guided light into mechanical motion. Their tethered‐flexible design enables minimally invasive surgery and confined‐space robotics. This review aims to guide materials selection, device design, and system integration, accelerating the transition of waveguide photoactuators from laboratory prototypes to versatile ...

Modelling of Oblique Wire Cutting and Experimental Application on Soft Solid Foods for the Investigation of Friction Behaviour

Journal of Food Quality, 2019
The sales value of ready-made foods is determined to a large extent by the appearance of the individual pieces or slices. Breakouts or deformations are perceived negatively and should be avoided. The quality of the cut surface is derived as an evaluation

Electrical Control of the Transduction Channels’ Gating Force in Mechanosensory Hair Cells

Advanced Science, EarlyView.
The inner ear's hair cells rely on mechanosensitive ion channels to convert vibrations of their hair‐bundle into electrical signals. We show that varying the electrical potential (U) across the sensory epithelium modulates a key determinant of mechanosensitivity—the gating force (FG)—by modulating the gating swing (d), ranging from the size of the ...

Robotic Materials With Bioinspired Microstructures for High Sensitivity and Fast Actuation

Advanced Science, EarlyView.
In the review paper, design rationale and approaches for bioinspired sensors and actuators in robotics applications are presented. These bioinspired microstructure strategies implemented in both can improve the performance in several ways. Also, recent ideas and innovations that embed robotic materials with logic and computation with it are part of the

Detonation interaction with an interface [PDF]

, 2007
Detonation interaction with an interface was investigated, where the interface separated a combustible from an oxidizing or inert mixture. The ethylene-oxygen combustible mixture had a fuel-rich composition to promote secondary combustion with the ...

Enzymatic Remodelling of Tumour Microenvironment Enhances Anti‐CEACAM5 CAR T‐Cell Efficacy Against Colorectal Cancer

Advanced Science, EarlyView.
This study shows anti‐CEACAM5 CAR T‐cells are ineffective against colorectal cancer (CRC) because of CEACAM5 sequestration at intercellular junctions and the thick tumour cell glycocalyx. Enzymatic treatments of CRC cell monolayer/tissue section with trypsin or hyaluronidase restore CEACAM5 availability, enhance CAR T‐cell activation, increase ...

A "Littlest Higgs" Model with Custodial SU(2) Symmetry

, 2003
In this note, a ``littlest higgs'' model is presented which has an approximate custodial SU(2) symmetry. The model is based on the coset space $SO(9)/(SO(5)\times SO(4))$.
