Phase‐Engineered MoS2 Quantum Monolayer Catalysts

Advanced Materials, EarlyView.
A new type of catalyst model—phase‐engineered MoS2 quantum‐monolayer catalyst (∼0.8 nm thick, < 6 nm in the lateral size; switchable freely among metallic 1T, semiconducting 2H, and a hybrid phase of metallic‐semiconducting 1T‐2H)—is reported. It can efficiently and stably drive photochemical H2, syngas and ammonia synthesis as a catalyst or co ...

From Dark Photocatalysis to Photobattery‐Type Operation: A Re‐Functionalized Ti‐MOF for Solar Energy Storage

Advanced Materials, EarlyView.
ReCl47‐bpy is developed as a solar‐rechargeable, Re‐functionalized two‐dimensional metal–organic framework (MOF) for light‐driven charge storage and dark utilization. Re–bipyridine sites stabilize photoinduced electrons, enabling two complementary configurations: a MOF suspension for long‐lived charge retention and dark H2 evolution, and a spin‐coated ...

Post-new-horizons Orbits and Masses for the Satellites of Pluto

The Astronomical Journal
We report on ephemerides for the satellites of Pluto based on the large set of astrometric measurements. Our orbit fit yielded the following masses with 1 σ uncertainties: GM _Pluto = 869.3 ± 0.4 km ^3 s ^−2 , GM _Charon = 106.1 ± 0.3 km ^3 s ^−2 , GM ...

Dynamically favorable hosts for submoons around Jupiter and Saturn

Astronomy & Astrophysics
Context. The long-term stability of small bodies orbiting natural satellites (submoons) in the Solar System has been previously investigated using an analytical approximation of a three-body problem, focusing mainly on tidal forces and neglecting other ...

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

A ring system detected around the Centaur (10199) Chariklo [PDF]

, 2014
Hitherto, rings have been found exclusively around the four giant planets in the Solar System1. Rings are natural laboratories in which to study dynamical processes analogous to those that take place during the formation of planetary systems and galaxies.
