Covalent Functionalization of NiFe Layered Double Hydroxides using Tris(Hydroxymethyl)Aminomethane

open access: yesSmall, EarlyView.
Covalent functionalization of NiFe layered double hydroxides with tris(hydroxymethyl)aminomethane enables controlled growth, enhanced structural order, and improved processability. Temporary TRIS anchoring promotes stable water‐based inks and binder‐free electrode fabrication, leading to enhanced oxygen evolution activity and long‐term stability under ...

Imaging Ionic Displacements Across Inclined Ferroelectric Domains by a Reciprocity Approach to 4D‐STEM

open access: yesSmall, EarlyView.
Four‐dimensional STEM comprises a vast portfolio of electron microscopy methods in one data set, conventional plane‐wave illumination TEM being one of them. Here, the principle of reciprocity is employed to produce true structural projections of misoriented ferroelectric domains at atomic resolution. By reciprocal TEM imaging from four‐dimensional STEM

Multi‐Scale 3D Printing of Magnetic Polymer Nanocomposites with Controlled Particle Dispersion and Hyperthermic Response

open access: yesSmall, EarlyView.
Dispersion of magnetic nanoflowers in trimethylolpropane ethoxylate triacrylate to generate photocurable nanocomposites is described. Particle dispersion provides processability and target AC‐field stimulated temperature increases. Complex (DLP) printed structures with submicron features are demonstrated, and the potential for stimulated release of ...

Deformation and strength of grouted sleeve connectors in pre‐fabricated concrete structures: Mechanisms and analytical modeling

open access: yesStructural Concrete, EarlyView.
Abstract Grouted sleeve connectors (GSCs) are widely used in precast/prefabricated concrete structures. To ensure force transfer, connectors are often overdesigned in length. This practice has an unintended consequence of reducing the plastic deformation capacity of the connection region and hence the displacement ductility of the precast structure as ...

Regression‐based models for the torsional stiffness reduction factor in reinforced concrete beams under combined torsion and shear

open access: yesStructural Concrete, EarlyView.
Abstract This paper presents a regression‐based methodology to estimate the Torsional Stiffness Reduction Factor (TSRF) of reinforced concrete beams under combined torsion and shear. A numerical database of 6816 samples was generated using the Combined Action Softened Truss Model (CA‐STM) implemented in Python, considering design guidelines prescribed ...
