Deformation Analysis of Large Diameter Monopiles of Offshore Wind Turbines under Scour
Applied Sciences, 2020 The displacement of monopile supporting offshore wind turbines needs to be strictly controlled, and the influence of local scour can not be ignored. Using p–y curves to simulate the pile–soil interaction and the finite difference method to calculate ...

Local Scour of Bridge Pier Sited on a Multi-Layered Sedimentary Bed in Rivers [PDF]
E3S Web of Conferences, 2020 The riverbeds or sea beds are usually composed of multi-layers of sediments. The scour around bridge piers sited on such beds is vital to the bridge safety, but is still very difficult to be predicated as its complicated interaction between the flow and ...

Advanced Functional Materials, EarlyView.A 3D bone scaffold with osteogenic properties and capable of hardening in vivo is developed. The scaffold is implanted in a ductile state, and a phase transformation of the ceramic induces the stiffening and strengthening of the scaffold in vivo. Abstract Calcium phosphate 3D printing has revolutionized customized bone grafting.

Experimental study of local scour around diamond bridge piers subject to transverse standing waves
Ain Shams Engineering Journal, 2022 Numerous bridges around the world have been destroyed due to local scour around their piers and abutments. Transverse standing waves (perpendicular to the flow direction) generated by obstacles, such as bridge piers, can affect the extent of local scour ...

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
