A Biologically‐Architected Wear and Damage‐Resistant Nanoparticle Coating From the Radular Teeth of Cryptochiton stelleri

open access: yesAdvanced Functional Materials, EarlyView.
The ultrahard teeth of mollusks that feed on rocky substrates contain a wear‐resistant coating on their surfaces consisting of densely packed mesocrystalline magnetic nanoparticles within an organic matrix. These coatings display significant hardness and toughness through their highly controlled mesocrystalline architectures.

Self‐Reconstruction of Dual‐Morphology Copper‐Iron Selenides for Cost‐Effective Oxygen Evolution Toward Industrial Alkaline Water Splitting

open access: yesAdvanced Functional Materials, EarlyView.
Departing from conventional Ni/Co‐based catalysts, this work presents a Ni/Co‐free CuFe–Se/CFF electrocatalyst with nanoblock–nanorod morphology. It delivers 1000 mA cm−2 at 330 mV overpotential and 620 h stability for the oxygen evolution reaction (OER).

Synthetic Antiferromagnetic Designer Nanodisks for High‐Performance Magnetic Separation

open access: yesAdvanced Healthcare Materials, EarlyView.
Micromagnetic‐modeling‐based design and scalable fabrication of synthetic antiferromagnet (SAF) magnetic disk particles (MDPs) using sputter deposition enable high‐performance magnetic separation. The SAF MDPs achieve high colloidal stability and magnetic responsiveness and enable efficient magnetic separation, outperforming conventional particles ...

Biomimetic Mineralization of Keratin Scaffolds for Enamel Regeneration

open access: yesAdvanced Healthcare Materials, EarlyView.
Keratin‐based films guide biomimetic enamel remineralization by promoting organized hydroxyapatite growth under physiological conditions. Advanced biophysical characterization confirms keratin's structural adaptability and mineral ions‐binding affinity, supporting mineral nucleation and hierarchical crystal assembly. This study establishes keratin as a

Comparison of bridge design in Malaysia between American codes and British codes [PDF]

open access: yes, 2005
The design of a highway bridge, like most any other civil engineering project, is dependant on certain standards and criteria. Naturally, the critical importance of highway bridges in a modern transportation system would imply a set of rigorous design ...

Fatigue‐Resistant Mechanoresponsive Color‐Changing Hydrogels for Vision‐Based Tactile Robots

open access: yesAdvanced Materials, EarlyView.
Mechanoresponsive color‐changing materials that can reversibly and resiliently change color in response to stress are highly desirable for diverse technologies in optics, sensors, and robots; however, such materials are rarely achieved. This work reports a fatigue‐resistant mechanoresponsive color‐changing hydrogel that exhibits reversible, resilient ...
