Advanced Materials, EarlyView.A mechanochemically synthesized dual‐site electrocatalyst (RuNC@Fe1NC) accelerates alkaline hydrogen evolution via atomic‐level spatial decoupling. Oxophilic Fe single atoms effectively dissociate water, while adjacent Ru nanoclusters rapidly recombine hydrogen.

The Astrophysical Journal LettersThe origin of hot Jupiters remains a key open question. In the high-eccentricity migration scenario, traditional coreless models predict a strict tidal exclusion zone within ∼2.7 tidal radii r _t , in which giant planets are either fully disrupted or ...

Photocatalytic Water Splitting on the Lunar Surface: Prospects for In Situ Resource Utilization
Advanced Materials Interfaces, EarlyView.Water has been found in craters on the moon nearby locations which are illuminated >80% of the time. Photocatalysis uses energy from sunlight to drive chemical reactions such as water splitting to produce oxygen and hydrogen. It is a scalable technology that requires lighter equipment and utilizes resources available on the moon. ABSTRACT The discovery

Advanced Materials Interfaces, EarlyView.Imide substitution with bulky 2,6‐isopropylphenyl groups induces perylene diimide to self‐assemble on Ag(111) into a monolayer with two coexisting adsorption heights. Molecules closer to the substrate gain metallic character due to charge transfer from the metal, while farther ones remain decoupled and semiconducting.

No Signature of the Birth Environment of Exoplanets from Their Host Stars’ Mahalanobis Phase Space
The Astrophysical JournalThe architectures of extrasolar planetary systems often deviate considerably from the “standard” model for planet formation, which is largely based on our own solar system.

Advanced Materials Interfaces, EarlyView.The deposition of Iron on pristine MoS2/Au(111) monolayers produces nanoparticles that donate charge to the support, generating Fe+2‐interfacial species. On the contrary, on defect‐engineered MoS2, sulfur vacancies trap sub‐nanometric Fe clusters and host two excess electrons that redistribute locally, suppressing Fe oxidation without formal Mo ...

The JWST/NIRISS Deep Spectroscopic Survey for Young Brown Dwarfs and Free-floating Planets
The Astronomical JournalThe discovery and characterization of free-floating planetary-mass objects (FFPMOs) is fundamental to our understanding of star and planet formation. Here we report results from an extremely deep spectroscopic survey of the young star cluster NGC1333 ...

Large-Scale Searches for Brown Dwarfs and Free-Floating Planets [PDF]
, 2018 Searches of large scale surveys have resulted in the discovery of over 1000 brown dwarfs in the Solar neighbourhood. In this chapter we review the progress in finding brown dwarfs in large datasets, highlighting the key science goals, and summarising the surveys that have contributed most significantly to the current sample.
