The Bright Rim Prominences according to 2.5D Radiative Transfer

The Astrophysical Journal Letters
Solar prominences observed close to the limb commonly include a bright feature that, from the perspective of the observer, runs along the interface between itself and the underlying chromosphere. Despite several idealized models being proposed to explain

From Flybys to Sample Return: A Review of Space Probes and Robotic Sampling Technologies for Small Bodies

Journal of Field Robotics, EarlyView.
ABSTRACT As a crucial puzzle piece of deep space exploration, exploring small bodies can provide significant scientific insights and valuable mineral resources. Unlike missions to the Moon and Mars, small‐body missions pose distinct technical challenges, including communication delays, weak gravity, and uncertain environments. This paper reviews a full

A Catalog of Filaments in the Central Molecular Zone

The Astrophysical Journal Supplement Series
We present a catalog of 1.28 GHz radio filaments observed by MeerKAT over the innermost 200 pc of the Galaxy (roughly ±1 $\mathop{.}\limits^{\unicode{x000b0}}$ 5), which includes the central molecular zone.

Development and Evaluation of a Low‐Cost, Semi‐Automated Camera Trap for Surveying Bumble Bee Communities

Remote Sensing in Ecology and Conservation, EarlyView.
Camera traps are emerging as a useful tool for noninvasive insect monitoring; however, it remains unclear how to lure diurnal insects to traps, how to detect them upon arrival, and how camera‐based methods compare to conventional sampling. We developed a low‐cost, open‐source camera trap to monitor wild bumble bees in agricultural fields. We found that

The Observations of Magnetic Reconnection during the Interaction Process of Two Active Region Filaments

The Astrophysical Journal
We investigate the interaction between two filaments (F1 and F2) and their subsequent magnetic reconnection in active region (AR) NOAA 13296 and AR NOAA 13293 on 2023 May 9, utilizing high spatial and temporal resolution and multiwavelength observational

MXene‐Based Flexible Memory and Neuromorphic Devices

Small, 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,

Deciphering the Formation and Dynamics of Double-decker Filaments through Component Magnetic Reconnection

The Astrophysical Journal Letters
The formation of double-decker filaments has long been an enigma in the field of solar physics. Using stereoscopic observations from the Solar Dynamics Observatory and the Solar Terrestrial Relations Observatory, we show that the double-decker filament ...

Low Temperature Site‐Specific Pulsed Laser Annealing of MoS2

Small, 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 ...

Self‐Doped Perylene Diimide‐Based Polymers for Simultaneous Improvements in Efficiency and Thermal Stability of Organic Solar Cells

Small, EarlyView.
PPV‐M, an amorphous electron transporting polymer with a high Tg of 118°C, suppresses thermally induced molecular diffusion in organic solar cells. Unlike crystalline PDINN (Tg = 61°C) with a T80 of only 8 h, PPV‐M maintains efficient electron extraction and extends T80 to 637 h, representing an 80‐fold enhancement in thermal stability.

Martian‑Regolith Simulant Confined Nanogenerators for Wireless Tactile Sensing for Human‐Machine Interface

Small, EarlyView.
A Martian regolith‐simulant/PDMS triboelectric nanogenerator is developed as an ISRU‐inspired, self‐powered tactile sensor for wireless human–machine interface applications. ABSTRACT Achieving a sustainable energy system for space missions remains challenging due to the continued reliance on Earth‐supplied materials.
