Inside the Microreactor: In Situ Real‐Time Observation of Vapor–Liquid–Solid Growth of Monolayer TMDCs

Advanced Science, EarlyView.
In situ observation of VLS growth in a confined microreactor reveals various growth modes of monolayer TMDCs, including abnormal ribbon growth and particle‐driven growth. The confined space and precursor balance influence droplet behavior and growth dynamics, offering new insights into the controlled synthesis of TMDCs via the VLS mechanism.

New Horizons Venetia Burney Student Dust Counter Observes Higher than Expected Fluxes Approaching 60 au

The Astrophysical Journal Letters
The NASA New Horizons Venetia Burney Student Dust Counter (SDC) measures dust particle impacts along the spacecraft’s flight path for grains with mass ≥10 ^−12 g, mapping out their spatial density distribution.

Physical Origin of Temperature Induced Activation Energy Switching in Electrically Conductive Cement

Advanced Science, EarlyView.
The temperature‐induced Arrhenius activation energy switching phenomenon of electrical conduction in electrically conductive cement originates from structural degradation within the biphasic ionic‐electronic conduction architecture and shows percolation‐governed characteristics: pore network opening dominates the low‐percolation regime with downward ...

Dual Sources of S2 Observed in Comet 67P: Insights from Comparing ROSINA Measurements and Laboratory Simulations

The Planetary Science Journal
Hydrogen sulfide (H _2 S) is the fifth most abundant molecule observed in the coma of comet 67P/Churyumov–Gerasimenko (67P). Prior to its incorporation into cometary materials, H _2 S likely underwent ultraviolet (UV) radiation exposure, which is thought

NIR Light‐Driven Photocatalytic Antibacterial Hydrogels for Synergistic MRSA Biofilm Eradication and Wound Regeneration

Advanced Science, EarlyView.
The nanohybrid hydrogel (Fe‐BOS@C/H Gel) is composed of Fe‐Bi2O2‐XS (Fe‐BOS) photocatalysts and CS‐ADH/OHA (C/H) hydrogel. Fe‐BOS photocatalysts achieve near‐infrared (NIR) light‐driven antibacterial photocatalytic/mild photothermal therapy (APCT/MPTT), effectively eliminating methicillin‐resistant Staphylococcus aureus (MRSA) biofilms. The degradation

Truncated Conjugate Structure Improves Solar‐Driven Hydrogen Peroxide Production Catalyzed by Benzobisthiazole‐Based Conjugated Polymers

Advanced Science, EarlyView.
In this work, a novel molecular design strategy was employed to truncate large‐scale conjugated structures in covalent polymer materials. This approach significantly enhances the catalyst’s light‐harvesting capability, prolongs the lifetime of photogenerated charge carriers, and improves catalytic activity, thereby offering a new conceptual pathway for

The Weird and the Wonderful in Our Solar System: Searching for Serendipity in the Legacy Survey of Space and Time

The Astronomical Journal
We present a novel method for anomaly detection in solar system object data in preparation for the Legacy Survey of Space and Time. We train a deep autoencoder for anomaly detection and use the learned latent space to search for other interesting objects.
