Numerical Modeling of Solitary Wave-Induced Flow and Scour around a Square Onshore Structure

Journal of Marine Science and Engineering, 2023
Waves or tsunamis in the onshore area could induce severe scour at the structure foundations, threatening the stability of the structure. This paper presents a numerical study of the solitary wave-induced flow and scour around a square onshore structure.

Reevaluating the Activity of ZIF‐8 Based FeNCs for Electrochemical Ammonia Production

Advanced Functional Materials, EarlyView.
Though receiving much attention, the field of electrochemical nitrogen reduction reaction (eNRR) to ammonia is marked by doubts about whether this reaction is possible in aqueous media. This work sheds light on this question for iron single‐atom on N‐doped carbon (FeNC) catalysts—a class of well‐known catalysts that is also worth testing for the sister

Reducing Open‐Circuit Voltage Losses in Wide‐Bandgap FAPbBr3 Perovskite Solar Cells for Continuous Unassisted Light‐Driven Water Splitting

Advanced Functional Materials, EarlyView.
The combination of formamidinium thiocyanate and 1,3‐propane diammonium iodide for bulk and top‐surface passivation, and a ternary fullerene blend to improve energy band alignment, suppresses energy losses in wide‐bandgap FAPbBr3 perovskite solar cells.

Effect of flow deflectors on local scour around artificial reefs under steady current: Experimental and numerical investigations

Applied Ocean Research
Artificial reefs are submerged structures used to rehabilitate marine ecosystems and restore fishery resources. Field investigations have revealed that local scour poses a significant threat to these structures in various regions.

The Impact of Scour on Laterally Loaded Piles Bored and Socketed in Marine Clay

Journal of Marine Science and Engineering, 2022
The majority of long-span bridges and offshore construction in deep water are supported by bored pile foundations. Pile foundations under water will be susceptible to scour, which will pose a significant danger to their safe operation.
