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 ...

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

Transient mechanics of bed load sediment transport
, 2013 Bed load transport, the movement of sediment by water or air in close proximity to the river bed or ground surface, is governed by complex interactions among fluid, particles, and evolving bed topography.

The Hydraulics of Open Channel Flow: an Introduction. Sediment Transport Mechanisms 1. Bed-load Transport [PDF]
, 1999 When the bed shear stress exceeds a critical value, sediments are transported in the form of bed-load and suspended load. For bed-load transport, the basic modes of particle motion are rolling motion, sliding motion and saltation motion (Fig. 10.1).

Advanced Materials Interfaces, EarlyView.Atomistic simulations reveal the interlayer mechanics of additively manufactured materials, showing how build direction and layer interfaces govern diffusion, defect evolution, and mechanical strength. Distinct anisotropic behavior arises from interface‐controlled deformation and dislocation activity, establishing critical links between microstructural
