Giga‐Voxel Multiscale Composite Architecture Mirrored Through a Data‐to‐Model Closed‐Loop Digital Twin

open access: yesAdvanced Materials, EarlyView.
Herein, a systematic digital twin workflow tailored for generating high‐fidelity virtual representations of anisotropic composite microstructures and giga‐voxel meso‐structural models is presented, leveraging a harmonious integration of top–down image‐based modeling and bottom–up data‐driven voxel generation.

Whipping Instabilities in Electrified Liquid Jets

open access: yes, 2008
A liquid jet may develop different types of instabilities, like the so-called Rayleigh-Plateau instability, which breaks the jet into droplets. However, another type of instabilities may appear when we electrify a liquid jet and induce some charge at his

Temperature‐Tunable Heliconical and Ferroelectric Nematics for White Lasing

open access: yesAdvanced Materials, EarlyView.
The discovery of the ferroelectric nematic (NF) phase in 2017 and the spontaneous symmetry‐breaking of the ferroelectric twist‐bend nematic (NTBF)phase in 2024 have made major breakthroughs in the context of self‐assembly materials. This study presents pioneering temperature and voltage‐tunable lasing in both phases, demonstrating multicolor and in ...

Sustainable Liquid Metal Composites for Soft Electronics and E‐Waste Reduction

open access: yesAdvanced Materials, EarlyView.
Liquid metal (LM) composites embody recyclability, repairability, renewability, and resilience (4R), offering a sustainable route for soft electronics. With exceptional conductivity, stretchability, and eco‐friendly recovery, these systems enable closed‐loop lifecycles and reduce e‐waste.

Tuning the Surface State and Zeta Potential of Aged CuO Nanoparticles by Additive‐Free Surface Treatments as Guided by XPS

open access: yesAdvanced Materials, EarlyView.
Aging of CuO nanoparticles (NP) involves a surface reconstruction induced by hydroxylation and concurrent organic‐O adsorption, which introduces O defects in the NP subsurface region. The defective surface results in a diffuse surface space region, as reflected by a low ζ‐potential of the aged NPs in ethanol solvent.

Quadruple Helix Inversions of Liquid Crystals Orchestrated by Direct Chirality Transmission of an Intrinsically Chiral Light‐Driven Molecular Machine

open access: yesAdvanced Materials, EarlyView.
A molecular motor with four‐state dynamic chirality is integrated into liquid crystals, enabling quadruple sequential helix inversions and high helical twisting power. Due to high motor efficiency, the supramolecular helicity can be controlled by near‐infrared light via upconversion nanoparticles, resulting in a robust, multistate, photoresponsive soft
