Research into the Magnetic Configuration of Eruptive Filaments with a High-class Flare

open access: yesThe Astrophysical Journal
Filament eruptions are the source of coronal mass ejections, and these phenomena are likely to pose a serious threat to space weather safety. The magnetic structures that carry the filament material are considered the core structures of the eruption, and

From 0D to 3D liquid crystal elastomers architectures: Fabrications and applications

open access: yesResponsive Materials, EarlyView.
This review presents a dimension‐oriented overview of liquid crystal elastomers (LCEs), highlighting their molecular alignment, fabrication strategies, and programmable deformations from 0D particles to 3D architectures. Emphasis is placed on how dimensionality guides design principles, enables diverse actuation modes, and bridges fundamental ...

Quasiperiodic Slow-propagating Extreme-ultraviolet “Wave” Trains after the Filament Eruption

open access: yesThe Astrophysical Journal Letters
The eruption of the filament/flux rope generates the coronal perturbations, which further form extreme-ultraviolet (EUV) waves. There are two types of EUV waves, namely, fast-mode magnetosonic waves and slow waves.

MXene‐Based Flexible Memory and Neuromorphic Devices

open access: yesSmall, EarlyView.
The unique two‐dimensional structure, excellent electrical conductivity, and diverse surface groups of MXenes have garnered significant attention. Coupled with their exceptional flexibility, MXene‐based devices hold immense potential for flexible memory and neuromorphic systems. This review comprehensively discusses the fundamentals of flexible devices,

Initiation Route of Coronal Mass Ejections. II. The Role of Filament Mass

open access: yesThe Astrophysical Journal
A thorough understanding of the initiation of coronal mass ejections (CMEs), which is manifested as a slow rise of pre-eruptive structures before the impulsive ejection in kinematics, is key for forecasting solar eruptions.

Low Temperature Site‐Specific Pulsed Laser Annealing of MoS2

open access: yesSmall, EarlyView.
The application of laser pulses, of extremely short duration, is investigated as a potential new method to modify the atomic structure of ultrathin 2D materials for use in the creation of future electrical devices. The process is efficient, offering a site‐specific functionality, where regions of an electronic device that only requires annealing is ...

Do We Really Know Why Carbon Nanotubes Grow?

open access: yesSmall, EarlyView.
The CNT growth mechanism is still debated. We propose a heterogeneous (2D) classical nucleation framework comparing pathways for graphenic patches, caps, and full CNTs. Despite its simplicity, it rationalizes key trends, including the correlation between catalyst particle size and CNT diameter.

Triggering of the 2024 August 8 X1.3 Flare by Peripheral Flux Emergence

open access: yesThe Astrophysical Journal
We investigate an X1.3 flare in active region 13777 on 2024 August 8, which was preceded by precursor brightening associated with small-scale magnetic flux emergence and cancellation at the periphery of the leading polarity. Multi-instrument observations

Toward Efficient and Reliable Chemical Upgrading Using Solid Oxide Electrochemical Reactors, Mechanisms, Challenges, and Design Principles

open access: yesSmall, EarlyView.
Solid oxide electrochemical reactors (SOERs) offer a compelling pathway for coupling renewable electricity with chemical manufacturing, but their real application is still limited by low efficiency and instability. This review systematically summarizes SOER reaction mechanisms, performance‐limiting factors, and recent progress toward high‐efficiency ...
