Revealing the Underlying Mechanisms in Performance Enhancement of Shellular Lattice Electrodes During Anion Exchange Membrane Water Electrolysis Process

open access: yesAdvanced Science, EarlyView.
Micro laser powder bed fusion enables architected nickel shellular lattice gas diffusion layers for anion exchange membrane water electrolysis. Among regular open cell geometries, the Gyroid lattice promotes bubble release, convective reactant replenishment and continuous electron transport, delivering low overpotentials, enhanced charge transfer and ...

Analysis of the nodal stresses in pile caps

open access: yesRevista IBRACON de Estruturas e Materiais, 2018
Pile caps can be dimensioned using, preferably, plastic models (strut-and-tie) and models based on the flexion theory. In order to analyze the behavior of the stresses in the lower and upper nodal regions of the cap, a theoretical analysis of the ...

Osteohistology of two phorusrhacids reveals uninterrupted growth strategy

open access: yesThe Anatomical Record, EarlyView.
Abstract Phorusrhacidae were apex predators that primarily dominated South America ecosystems for at least 40 million years with their imposing size and predatory lifestyle—yet some aspects of their biology remain poorly understood. Osteohistology is a tool for understanding growth dynamics and biomechanical adaptations.

Investigating strut and tie model in deep beams [PDF]

open access: yes, 2021
The Strut-and-Tie model (STM) approach evolves as one of the most useful design methods for shear critical structures and for other disturbed regions in concrete structures. The model provides a rational approach by representing a complex structural member with an appropriate simplified truss model.

String Figuring young children's perspectives of quality in English early childhood education and care

open access: yesBritish Educational Research Journal, EarlyView.
Abstract Quality in early childhood education and care (ECEC) is a contested concept and has generally been conceptualised by inter‐related indicators such as staff qualifications, educational environment, policy or child‐to‐staff ratios. There has been a more limited emphasis on how young children might perceive and experience quality.

Strut-and-Tie Evaluation Program (STEP) for the Design of Bridge Components

open access: yes, 2019
The strut-and-tie method (STM) is a powerful tool used for the design of D-regions (disturbed regions) of reinforced concrete structures. Many typical bridge substructure components consist of D-regions and require the use of the STM for design ...

Nacre‐inspired layered composite with excellent mechanical support and osteogenic potential for cervical interbody cage

open access: yesBMEMat, EarlyView.
The cervical interbody cage needs to take both biomechanical and biological requirements into account. Here, a new‐style degradable, multicomponent, and bioinspired nacre‐like cervical interbody cage composite, which exhibits promising mechanical‐support‐related behavior and osteogenesis‐related potential, is designed and prepared.
