Rapid Impact Crater Relaxation Caused by an Insulating Methane Clathrate Crust on Titan

The Planetary Science Journal
Titan’s impact craters are hundreds of meters shallower than expected, compared to similar-sized craters on Ganymede. Only 90 crater candidates have been identified, the majority of which have low certainty of an impact origin.

Widespread Bomb Fishing in Indo‐Pacific Archipelago Revealed Through Machine Learning Accelerated Passive Acoustic Monitoring

Remote Sensing in Ecology and Conservation, EarlyView.
AI‐accelerated passive acoustic monitoring reveals extensive bomb fishing within the Spermonde Archipelago, with annual incidents numbering in the thousands. ABSTRACT Bomb fishing is recognised as the most destructive fishing practice that can be performed in our oceans.

The Hidden Harvest: Harnessing Colorado's Geodiversity and Environmental Heterogeneity for Sustainable Agritourism

Sustainable Development, EarlyView.
ABSTRACT Colorado's geologic, pedologic, topographic, hydrological, and climatic contrasts create strong but under‐synthesized opportunities for sustainable agritourism. This review investigates how geodiversity, and the broader environmental heterogeneity within which it operates, can be used to diversify farm income, strengthen place‐based visitor ...

Crater Equilibrium State Characterization given Crater Production from a Single Power Law

The Planetary Science Journal
We generalize the crater equilibrium concept, a terminal state on a cratered surface where the balance of crater production and erasure apparently limits the crater population from further growth. Assuming the crater production consists of a single power

Coregistration of Multimodal Imaging Mass Spectrometry and Optical Images of Tissue Sections at Single‐Cell Resolution

Surface and Interface Analysis, EarlyView.
ABSTRACT Accurate alignment of histopathological structures in optical images and imaging mass spectrometry (IMS) datasets is crucial for providing meaningful biological interpretation. Integrating IMS with optical or other imaging modalities remains challenging due to sample‐preparation constraints, mismatched spatial resolutions, and the need for ...

Rapid Fabrication of Sub‐100 µm Microstructures In Situ via Femtosecond Laser for Correlative Imaging of Rare Cells

Small, EarlyView.
In this work, a femtosecond (fs) laser processing strategy is demonstrated for rapid and targeted fabrication of 3D sub‐100‐µm microstructures on resin‐embedded cells. The fabricated array of sub‐100‐µm pillars (each loaded with flow‐sorted T‐cell subsets) is arranged in a half‐grid geometry to enable efficient use of the scarce biological sample and ...

Deep learning detects entire multiple-size lunar craters driven by elevation data and topographic knowledge

Geo-spatial Information Science
Lunar craters are important geomorphological features, that provide valuable insights into lunar morphology, geology, and impact processes. However, the current understanding of lunar craters of different sizes, especially smaller craters (diameter

Unraveling the Proton‐Induced Degradation Mechanism in Quantum‐Dots Light‐Emitting Diode for Space Applications

Small, EarlyView.
Low‐energy proton irradiation induces ligand detachment at the QD/ZnO interface in quantum‐dot light‐emitting diodes (QLEDs). The exposed ZnS surface interacts with ZnO defects, generating a high density of interfacial trap states that promote electron trapping, suppress charge injection, and accelerate non‐radiative recombination, ultimately leading ...

Tailoring Laser Powder Bed Fusion and Post‐Processing Parameters for JIS SKD61 Tool Steels: Surface Roughness, Microstructure, and Mechanical Properties

steel research international, EarlyView.
Laser powder bed fusion of JIS SKD61 tool steel is systematically optimized using a Taguchi design and ANOVA. Hatch spacing and layer thickness are identified as dominant parameters controlling surface roughness and tensile strength. Subsequent tempering at 600°C improves microstructural stability and mechanical performance, enabling high‐density SKD61

Effect of Different Surface Treatments on Resistance to Abrasive Wear of AISI 4140 Steel

steel research international, EarlyView.
This study investigates how different surface treatments affect resistance to abrasive wear of AISI 4140 Steel. The wear rate was significantly higher in samples subjected to conventional treatments than in samples coated using the HVOF process, demonstrating the superior efficiency of coatings applied by thermal spraying in mitigating abrasive wear ...
