Liquid Crystalline Self‐Assembly with Accelerated Kinetics and Higher Structural Orderliness in Centrifugal Acceleration Fields Beyond 7251 Times Gravity of Earth

open access: yesAdvanced Science, EarlyView.
How do chemical and physical processes involving multiple phases develop on compact astrophysical objects such as white dwarf stars? Herein, entropy‐driven self‐assembly of rod‐shaped nanoparticles in centrifugal acceleration fields up to 7251 times the gravity of Earth is investigated, where strong acceleration fields accelerated the kinetics of phase

Versatile and Robust Reservoir Computing with PWM‐Driven Heterogenous R–C Circuits

open access: yesAdvanced Science, EarlyView.
A robust physical reservoir computing (PRC) system using pulse‐width modulation (PWM)‐encoded R–C circuits is introduced. By enabling customizable nonlinearities and timescales, this system achieves state‐of‐the‐art accuracy in chaotic, multiscale, and multiclass tasks while maintaining stability across temperature variations and device batches.

Self‐Oscillation in Active Wires with Asymmetric Willis‐Type Viscosity

open access: yesAdvanced Science, EarlyView.
This study suggests a self‐oscillation strategy enabled by a new set of material parameters, namely the asymmetric Willis‐type viscosity, to bias and independently control oscillation mode shapes as well as frequencies. The exemplified active wire can benefit the development of autonomous materials to construct soft motors, agitators, pumps, and ...

2D Conductive MOFs Intercalated in MXene Interlayer for Fast and Trace Detection of Triethylamine at Room Temperature

open access: yesAdvanced Science, EarlyView.
This study presents alternating MXene@Cu‐HHTP (HHTP = 2,3,6,7,10,11‐hexahydroxytriphenylene) heterostructures with a sandwich‐like architecture, combining 2D conductive metal–organic frameworks (2D‐cMOFs) and Ti3C2TX MXene to enhance triethylamine (TEA) sensing. The composite achieves rapid response (4 s at 50 ppm), ultralow detection limit (1 ppm), 21‐

High‐Gain PMMA‐Modified Graphene Photodetectors for Dual‐Wavelength Secure Communication Utilizing Distinct Temporal Photoresponses

open access: yesAdvanced Science, EarlyView.
The bipolar photoresponses with temporally distinguishable characteristics in a PMMA‐modified graphene photodetector are successfully achieved. Through systematic harnessing of these wavelength‐dependent temporal dynamics as encrypted and key signals, an effective encryption system for optical communication systems is developed.

Potent Cross‐neutralizing Antibodies Reveal Vulnerabilities of Henipavirus Fusion Glycoprotein

open access: yesAdvanced Science, EarlyView.
Hendra and Nipah viruses (HNVs) pose significant threats to global health. This work reports potent cross‐neutralizing antibodies targeting the fusion glycoprotein (F) and reveals shared features of these antibodies and vulnerabilities of F, thereby guiding the rational design of countermeasures against HNVs and similar pathogens.

Chaotic dark matter

open access: yesPhysical Review D, 1992
A very weakly coupled scalar field with mass $m$ and initial vacuum expectation value $V$ will provide enough mass to close the universe provided $V\simeq (3\times 10^8\gev)(100\gev/m)^{1/4}$. We discuss possible models in which such a field could arise.

Protected Chaos in a Topological Lattice

open access: yesAdvanced Science, EarlyView.
Topological and chaotic dynamics are often considered incompatible, with one expected to dominate or disrupt the other. This work reveals that topological localization can persist even under strong chaotic dynamics and, counter‐intuitively, protect chaotic behavior.

Aerial Track‐Guided Autonomous Soft Ring Robot

open access: yesAdvanced Science, EarlyView.
Controlling motion paths in soft active material‐based robots is challenging due to their inherently high degrees of freedom. Inspired by aerial trams, a new class of autonomous, track‐guided soft robots composed of twisted liquid crystal elastomer rings are reported.
