The Influence of Rainfall and Evaporation Wetting–Drying Cycles on the Open-Pit Coal Mine Dumps in Cam Pha, Quang Ninh Region of Vietnam

Applied Sciences
Among the slope hazards caused by rainfall, not all of them occur directly during storm washout, and the wetting–drying cycles’ effect on the rainfall–evaporation process is an important cause of shallow slope instability. In this study, taking the slope

Modelling unsaturated soil slopes subjected to wetting and drying cycles

, 2008
Water infiltration changes the pore pressure distribution in unsaturated slopes leading to slope movement, and therefore has been one of the most common triggering mechanisms for landslides in tropical areas.

Ionic Precursors Transformed Into Vinyl Acetate Synthesis Catalyst via Reaction‐Driven Restructuring

Advanced Functional Materials, EarlyView.
This work demonstrates that a simple physical mixture of Pd and Au ionic precursors, KOAc promoter, and SiO2 support can transform into a highly active vinyl acetate synthesis catalyst through reaction‐driven restructuring. The results highlight reaction‐induced restructuring as an innovative and sustainable catalyst design strategy.

Impact of Wetting and Drying Cycles on Durability of Lightweight Cemented Soils

IOP Conference Series: Earth and Environmental Science
Abstract Treated soils used in geotechnical applications undergo periodic wetting-drying cycles owing to the alternation of the rainy and dry seasons, affecting their mechanical behaviour and performance. The effects of wetting and drying cycles on the mechanical behaviour of Lightweight Cemented Soils are investigated in the present ...
