Upcycling Keratin‐Based Textile Waste Into High‐Performance Hybrid Fibers Via Tuning the Interfacial Interactions

Advanced Functional Materials, EarlyView.
Keratin recovered from animal‐hair textile waste is fractionated and blended with cellulose to produce continuously spun hybrid fibers. Selecting the high‐molecular‐weight keratin fraction enables 30 wt.% keratin incorporation while maintaining high strength in dry and wet states.

Biodegradable 3D‐Printable and Coatable Antifouling Composites for Marine Applications

Advanced Functional Materials, EarlyView.
Marine biofouling damages submerged surfaces and raises greenhouse gas emissions. Biodegradable antifouling biocomposites were developed by hot‐mixing beeswax, Tween 80, and calcium stearate or stearic acid. Adjusting the component ratio enables processing via hot‐pressing, 3D‐printing, or dip‐coating.

Deceleration of porous magnesium alloy scaffold degradation and synchronization of bone defect repair by LIPUS-activated piezoelectric mineralization barrier

Journal of Magnesium and Alloys
Biodegradable magnesium alloys exhibit significant potential for application in bone defect repair owing to their excellent mechanical properties and biocompatibility. Low-intensity pulsed ultrasonography (LIPUS) is a potential intervention for promoting

Fabrication and Characterization of Mg(OH)2 Films on AZ31 Magnesium Alloy by Alkali Treatment

International Journal of Electrochemical Science, 2017
Mg and its alloys have shown potential application as a bio-absorbable biomaterial, such as for bone screws and plates, however, their fast corrosion rate may result in the sudden failure of the implants. In this paper, compact and dense films are formed

Analog Classification of Human Hand Gestures Exploiting Dendritic Integration With an Organic Artificial Soma

Advanced Functional Materials, EarlyView.
An organic neuromorphic architecture for the classification of human motor behavior is presented and validated. It performs somatic integration by linearly combining the activity from three muscles. An investigation of synaptic weights is presented and discussed in relationship with the classification performance.

Bio‐Inspired Multifunctional Superhydrophilic Coatings With Remarkably Fast Self‐Healing Abilities

Advanced Functional Materials, EarlyView.
We developed bio‐inspired multifunctional hydrogel‐based coatings that exhibit extremely fast/repeatable self‐healing abilities, long‐lasting anti‐fogging performance, superhydrophilicity in air, and underwater superoleophobicity. By doping multivalent metal‐ions into the hydrogel networks, which promoted hydrogen bonding formation and enhanced the ...

Fe modified Ca-Mg-P coating with synergistic antibacterial, photothermal and osteogenic properties on magnesium alloys

Journal of Magnesium and Alloys
The overly rapid degradation rate and uneven corrosion remain the main obstacles restricting the application of bio-magnesium alloys. Owing to their excellent biocompatibility and corrosion resistance, phosphate coatings are being increasingly applied to
