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.

Microneedle‐Based Biofertilizer Delivery Improves Plant Growth Through Microbiome Engineering

open access: yesAdvanced Functional Materials, EarlyView.
This figure shows how microneedles are used to deliver biofertilizers to enhance plant growth through microbial migration, metabolic reprogramming, and changes in plant endogenous microbiome. Abstract This study presents a microneedle‐based system for the delivery of rhizospheric biofertilizers into plant tissues to enhance growth.

On the crescentic shape of barchan dune

open access: yes, 2004
Aeolian sand dunes originate from wind flow and sand bed interactions. According to wind properties and sand availability, they can adopt different shapes, ranging from huge motion-less star dunes to small and mobile barchan dunes.

Membrane Wrapping for High Capacity and Rapidly Switchable Adhesives

open access: yesAdvanced Functional Materials, EarlyView.
A membrane‐wrapping mechanism enables high‐capacity, rapidly switchable adhesion by coupling suction, friction, and adhesion. Broadband performance is achieved in dry and underwater conditions, allowing fast, reversible manipulation of objects of diverse sizes and shapes, from delicate eggs and berries to flat, complex, or heavy objects. These outcomes

Squeaking Sand versus Musical Sand [PDF]

open access: yesNature, 1890
ALLOW me to use your columns to thank Mr. Henry C. Hyndman for the reference in NATURE of October 2 (vol. xlii. p. 554) to a locality of sonorous sand in the interior of South Africa. Its occurrence in the interior is new to me, though it has been reported from the west coast at Liberia, and at Cape Ledo, from which latter place my friend, Mr.
