Plasma Electrolytic Oxidation Coatings on Lightweight Metals

, 2013
Lightweight metals, e.g. aluminum (Al), magnesium (Mg), titanium (Ti) and their alloys are of great importance for applications in various machinery and transportation system, espe‐ cially in aerospace and automobile products due to their high strength-to-weight ratio and superior physical and chemical performances.

Tuning the Electronic Structure and Spin State of Fe─N─C Catalysts Using an Axial Oxygen Ligand and Fe Clusters for High‐Efficiency Rechargeable Zinc–Air Batteries

Advanced Functional Materials, EarlyView.
A FeN4─O/Clu@NC‐0.1Ac catalyst containing atomically‐dispersed FeN4─O sites (medium‐spin Fe2+) and Fe clusters delivered a half‐wave potential of 0.89 V for ORR and an overpotential of 330 mV at 10 mA cm−2 for OER in 0.1 m KOH. When the catalyst was used in a rechargeable Zn–air battery, a power density of 284.5 mW cm−2 was achieved with excellent ...

Photo‐Switching Thermal and Lithium‐Ion Conductivity in Azobenzene Polymers

Advanced Functional Materials, EarlyView.
Light‐responsive azobenzene polymers control thermal and ionic transport simultaneously through structural transitions. UV illumination disrupts π–π stacking, converting crystalline trans states to amorphous cis configurations. Thermal conductivity drops from 0.45 to 0.15 W·m−1·K−1 while Li+ diffusivity increases 100 fold. This dual transport switching

Mechanotransducing Organic Electrochemical Diode for Crosstalk‐Inhibited Artificial Skin

Advanced Functional Materials, EarlyView.
An innovative approach is presented to a stretchable mechanotransducing diode that unifies rectification and tactile‐sensing functionality. This approach enables to fabricate the diode that maintains a large rectification ratio (5 × 102) at a high operational frequency (100 Hz).

Enhancing and Stabilizing Hydrogen Catalysis Through [NiFe]‐Hydrogenase Immobilization Within Macroporous Covalent Organic Frameworks

Advanced Functional Materials, EarlyView.
[NiFe]‐hydrogenases efficiently catalyze hydrogen conversion, but their instability limits biotechnological applications. Here it is shown that encapsulating hydrogenase into hierarchical COFs with macro‐ and micropores and functionalized with sulfonic or carboxylic acid groups improves enzyme stability and electron transfer to electrodes.

Plasma electrolytic oxidation coatings with particle additions – A review

Surface and Coatings Technology, 2016
Abstract Plasma electrolytic oxidation (PEO) processing for light metals is known for decades and has been established as a well-known industrial surface treatment offering a reasonable wear and corrosion protection. However, long-term protection is compromised by the intrinsic porosity and limited range of composition in the PEO layer.
