Hundred‐Nanometer‐Thick Stretchable Liquid Metal Films for Ultra‐Conformal Bioelectrodes

Advanced Science, EarlyView.
A low‐temperature deposition strategy is proposed to fabricate 19 nm‐thick liquid metal nanofilms (conductivity: 3 × 10⁶ S m−1) for developing ultra‐thin, high‐conductivity epidermal electrodes. The 1 µm‐thick composite achieves 8.5 kΩ skin contact impedance and 26 dB EMG SNR, enabling robust dynamic electromyography during movement.

Exploring the Effects of the Spatial Distribution of Catalytic Sites on Sulfur Nucleation Behaviors and Electrochemical Performances of Lithium–Sulfur Batteries

Advanced Science, EarlyView.
The effects of catalytic site distributions on Li2S nucleation behaviors and electrochemical performances in lithium–sulfur batteries are systematically explored. This study demonstrates how tailoring the spatial arrangement of catalytic sites can control sulfur deposition behavior, leading to enhanced battery performances.

The generalized discrete fourier transform for the computation of the DFT on large sets of data

, 1977
In this paper we consider a generalized form of the Discrete Fourier Transform (DFT), called Generalized Discrete Fourier Transform (GFT). Two fast algorithms are given that allow us to obtain a one-dimensional GFT by evaluating a proper multidimensional GFT.

Sustained and Efficient Ethanol Oxidation by Tethering Tunable N‐Donors Onto Integrated MXene/Pd‐Electrodes

Advanced Science, EarlyView.
Three novel 3D layered integrated electrodes for Pd‐catalysed ethanol oxidation are developed; their innovative design features N‐heterocyclic amide linkers grafted on an MXene, co‐anchoring Pd nanoparticles via “hand‐in‐hand” coordination. The resulting well‐defined Pd (111) catalytic sites help achieve extremely stable long‐term cycling with ...

Topologically Protected Negative Entanglement

Advanced Science, EarlyView.
It is revealed that topological flat‐band edge states can lead to robust unconventional negative entanglement entropy scaling. This arises from a new mechanism of non‐Hermitian critical skin compression (nHCSC), which strongly “compresses” quantum information beyond flat‐band degeneracy.

Surface Adhesion Engineering for Armored Metasurfaces and Beyond

Advanced Science, EarlyView.
Targeting primary causes of dysfunctionality in optical systems, an “armored” metasurface is developed based on Persson's model and Hertzian theory, enabling anti‐dust, anti‐scratch, anti‐impact, and anti‐water, heat resistance capabilities, alongside excellent optical antireflection performance.
