Advances in Electroactive Liquid Crystal Elastomers for Intelligent Robotics and Electronics
Advanced Robotics Research, EarlyView.Electroactive liquid crystal elastomers (eLCEs) integrate molecular anisotropy with electrical functionality to enable programmable actuation and reconfigurable electronics. This review classifies eLCEs into robotic actuators and adaptive electronics, summarizes key actuation mechanisms, and highlights fabrication strategies that bridge materials to ...

Formation of a Solar Filament Channel
The Astrophysical Journal, 1997 We present observations of the early stages of formation of a filament channel when a compact activity complex emerged in a previously quiet, near-equatorial area. In a few hours, and while flux was rising rapidly in one bipolar component in the complex, Hα fine structure overlying a polarity inversion zone organized into a conspicuous pattern of ...

Where do solar filaments form? Consequences for theoretical models.
, 2008 This paper examines the locations where large, stable solar filaments form relative to magnetic bipoles lying underneath them. The study extends the earlier work of F.

Advanced Science, EarlyView.Facet‐engineered PVP‐capped CuFeSe2 nanocrystals exhibit potent, selective antifungal activity by strongly binding cell‐wall mannan, enabling vacuolar entry and organelle disruption. High‐index facets show superior mannan affinity, validated by theoretical calculations and experiments. CFS‐P induces vacuolar cavitation, mitochondrial abnormalities, and

Formation of an Intermediate Filament Driven by Small-scale Magnetic Reconnection
The Astrophysical Journal, 2023 We present the formation process of a filament in NOAA active region 12765 from 2020 June 5 to 8, using observations from the New Vacuum Solar Telescope, the Solar Dynamics Observatory, and the Global Oscillation Network Group. We found that intermittent

Photonic‐Enabled Energy‐Efficient Transparent Neuromorphic Computing Devices: A Review
Advanced Science, EarlyView.Transparent photonic neuromorphic computing devices merge optics and brain‐inspired computing to overcome von Neumann bottlenecks with ultrafast, low‐energy processing. By exploiting transparent oxides, 2D materials, phase‐change materials, and hybrid heterostructures, these platforms enable photonic synapses, memory, and logic for see‐through edge ...

Advanced Science, EarlyView.Conventional passive radiative cooling films rely on costly feedstocks and energy‐intensive fabrication, with poor end‐of‐life compatibility in agriculture. To address this challenge, a sustainable radiative cooling mulch (SRCM) is developed from waste maize leaves via spontaneous hydrogen‐bond self‐assembly.
