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

Interfacial Assembly of Dye‐Doped Microparticles Driven by Combined Optical and Non‐Optical Forces
Advanced Optical Materials, EarlyView.Optical trapping controls nano‐ and microparticle assembly using various forces, including absorption for photoexcitable resonant molecules. This study demonstrates photoexcitation‐mediated assembly, forming hexagonal‐close‐packed structures at the air/solution interface.

Linker‐Free Covalent DNA Functionalization of Quantum‐Grade Nanodiamonds
Advanced Optical Materials, EarlyView.Nanodiamond (ND) surface is terminated with azide groups via nucleophilic substitution and decarboxylative azidation. The resulting azidated NDs display high click reactivity while retaining the spin and charge properties of nitrogen‐vacancy centers.

Advanced Robotics Research, EarlyView.Combining a biomimetic soft‐robot with deep‐learning data analytics sheds light on a unique peripheral dynamics seen in the biosonar system of bats: Bats modulate their ultrasonic biosonar signals upon emission as well as reception with variable, yet highly coordinated motion patterns of their noseleaves and pinnae.

Theoretical Computer Science, 1991 AbstractA Horn spectrum is a spectrum of a Horn sentence. We show that to solve Asser's problem, and consequently the EXPTIME = ? NEXPTIME question it suffices to consider the class of Horn spectra. We also pose the problem whether or not the generator of every Horn spectrum is a spectrum. We prove that from a negative solution of the generator problem,

Recent Advances in Ene Reactions with Carbon Enophiles
Advanced Synthesis &Catalysis, EarlyView.Recent advances in the classical intra‐ and intermolecular ene nexus with carbon enophiles (alkenes, alkynes, arynes, and allenes) show a considerable increase in structural complexity and an enormous potential for functional applications in polymer science.

Advanced Sustainable Systems, EarlyView.Fluorine‐free microporous layers (MPLs) are optimized for hydrocarbon‐based proton exchange membrane fuel cells (PEMFCs) using vapor‐grown carbon fibers (VGCF), carbon black (CB), and a silane treatment. The effects of MPL composition on wetting behavior, permeability, electrical resistance, and electrochemical performance are investigated ...
