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.

Safety and efficacy of iron compounds (E1) as feed additives for all species: ferric oxide based on a dossier submitted by Poortershaven Industriële Mineralen B.V.

open access: yesEFSA Journal, 2016
The additive under assessment, ferric oxide, contains between 57% and 69% iron (Fe). The EFSA FEEDAP Panel could not conclude on the safety of ferric oxide for the target animals owing to that (i) the application of ferric oxide red is for all animal ...

Engineering Relative Spatial Structure of Dual Atomic Sites with Asymmetric Coordination for High‐Performance Hydrogen Evolution Activity

open access: yesAdvanced Functional Materials, EarlyView.
Dual‐atom catalysts featuring varying spatial configurations of metal sites (Pt1Fe1 DACs) are employed to systematically investigate the influence of spatial arrangements on the electronic structure and catalytic activity of active sites. Notably, the 3D asymmetric Pt1Fe1‐TAC dimer, featuring strong interatomic interactions, demonstrates superior ...

Bio‐Inspired Nanoarchitected LiFePO4 Cathodes

open access: yesAdvanced Functional Materials, EarlyView.
Lithium iron phosphate (LFP) is synthesized using a bio‐inspired method, using acidic macromolecules similar to those found in many calcareous mineralized organisms to modulate the morphology and crystal growth of LFP‐carbon composite particles. The observations from this process indicate a non‐classical crystallization process, which subsequently ...
