Structural Porosity and Low Mineral Density in Enamel Rods Drive Molar Incisor Hypomineralisation

open access: yesAdvanced Functional Materials, EarlyView.
This study uses advanced imaging modalities on multiple length scales to show that molar‐incisor hypomineralization does not present as a locally homogeneous pathology. Instead, microstructural defects, characterized through non‐mineralized, protein‐rich sheaths and an altered mineral structure in between prism rods, resulting in local differences in ...

Dense Nanofibrillar Collagen–Silica Hybrids with High Strength and ECM‐Mimetic Tissue Integration

open access: yesAdvanced Functional Materials, EarlyView.
Dense nanofibrillar collagen–silica hybrids are engineered by synchronizing collagen fibrillogenesis with silica condensation, producing printable scaffolds that unexpectedly approach native extracellular matrix organization and strength. These cell‐free constructs guide endogenous cell‐infiltration, enable localized matrix remodeling, and integrate ...

Cicada (Tibicen linnei) steers by force vectoring

open access: yesTheoretical and Applied Mechanics Letters, 2016
To change flight direction, flying animals modulate aerodynamic force either relative to their bodies to generate torque about the center of mass, or relative to the flight path to produce centripetal force that curves the trajectory.

The Flight of Birds and Other Animals [PDF]

open access: yesAerospace, 2015
Methods of observing birds in flight now include training them to fly under known conditions in wind tunnels, and fitting free-flying birds with data loggers, that are either retrieved or read remotely via satellite links. The performance that comes to light depends on the known limitations of the materials from which they are made, and the conditions ...

In Situ 3D Bioprinting: Impact of Cross‐Linking on the Adhesive Properties of Hydrogels

open access: yesAdvanced Functional Materials, EarlyView.
In situ 3D bioprinting enables the direct deposition of cell‐laden, adhesive biomaterials for on‐site tissue regeneration. This review provides a comprehensive overview of how cross‐linking influences the bioadhesive properties of hydrogels used in 3D bioprinting, highlighting cross‐linking triggers, bioadhesion mechanisms, polymer interpenetration ...

Illegal animal-origin products seized in baggage from international flights at São Paulo Guarulhos airport (GRU / SBGR), Brazil

open access: yesCiência Animal Brasileira, 2018
Air transportation is one of the most important means to introduce illegally imported animal-origin products into a country. Studies have demonstrated that these items pose a risk of disseminating diseases. São Paulo Guarulhos International Airport (GRU /

Clean Up Behind You ‐ Novel Patterning Approach for Solid Immersion Lenses

open access: yesAdvanced Functional Materials, EarlyView.
A focused ion beam (FIB) milling strategy enables rapid fabrication of solid immersion lenses (SILs) with smooth, debris‐free surfaces eliminating the need for post‐processing. The optimized pattern improves efficiency and surface quality. SILs containing NV centers are also investigated, confirming the technique's suitability for quantum and photonic ...

The Optimum Flight Speeds of Flying Animals

open access: yesJournal of Avian Biology, 1998
Conventional models of bird flight combine metabolic, mechanical, and aerodynamic components to calculate the rate of fuel consumption and power required for flight, from which we may derive the optimal speeds flying animals should use in different situations.

Strategies for Loading and Releasing Peptide Therapeutics in Biodegradable Carriers

open access: yesAdvanced Functional Materials, EarlyView.
A biodegradable carrier‐based peptide delivery system is a powerful treatment platform for diverse diseases, owing to its superior therapeutic efficacy and low toxicity. This review examines the conventional peptide‐loaded carrier fabrication process and its current limitations.

Shape‐Controlled Guanine Self‐Assemblies for Stable and Fast‐Ion Solid–Electrolyte Interphases in Sustainable Li Metal Batteries

open access: yesAdvanced Functional Materials, EarlyView.
The shape of guanine self‐assemblies is tuned by introducing alkyl (G8), fluoroalkyl (G8f), and oligoether (G8g) side chains into the G moiety. The scanning tunneling microscopy results and calculations show that the presence and type of the side chain strongly affect the G self‐assembly network.
