“Smart” micro/nano container-based self-healing coatings on magnesium alloys: A review

open access: yesJournal of Magnesium and Alloys, 2023
Coating technologies are a commonly used way to protect metals against corrosion. However, with more and more severe service environments of materials, many protective coating systems often are not environmentally friendly or toxic as in the case of ...

On chromaticity of hypergraphs

open access: yesDiscrete Mathematics, 2007
The authors consider an extension of the chromatic polynomial to hypergraphs and prove that uniform hypertrees and uniform unicyclic hypergraphs are chromatically characterized in the class of linear hypergraphs.

The chromaticity of wheels

open access: yesDiscrete Mathematics, 1984
A graph G is said to be chromatically unique, if \(P(H,\lambda)=P(G,\lambda)\) implies that H is isomorphic to G, where P(G,\(\lambda)\) denotes the chromatic polynomial of G. In this paper it is proved that the wheel \(W_{n+1}\) is chromatically unique if n is even but \(W_ 8\) is not chromatically unique.

Chromatic contrast detection in spatial chromatic noise [PDF]

open access: yesVisual Neuroscience, 2004
The spectral properties of chromatic-detection mechanisms were investigated using a noise-masking paradigm. Contrast-detection thresholds were measured for a signal with a Gaussian spatial profile, modulated in the equiluminant plane in the presence of spatial chromatic noise.

Progress in eco-friendly aerospace coatings: the future beyond chromates

open access: yesJournal of Electrochemical Science and Engineering
Aluminium alloys have a good strength-to-weight ratio and low density, but they are not impervious to corrosion. Therefore, it is necessary to evaluate their corrosion performance in the atmospheric environment.

Deep Learning–Based Extraction of Promising Material Groups and Common Features from High‐Dimensional Data: A Case of Optical Spectra of Inorganic Crystals

open access: yesAdvanced Intelligent Discovery, EarlyView.
We report a novel interpretation method for deep learning models based on feature extraction and clustering. Applying this method to an atomistic line graph neural network (ALIGNN) model trained on optical absorption spectra of 2,681 inorganic compounds obtained from first‐principles calculations, we successfully identify key factors underlying ...

Corrosion Inhibition of a Cu-Ni Alloy in LiBr+Ethylene Glycol+H2O Mixtures with Nitrates, Chromates and Molybdates

open access: yesInternational Journal of Electrochemical Science, 2014
A study of the corrosion inhibition of a 90(wt.%)Cu-10Ni alloy in a 55LiBr+ethylene glycol+H2O solution by using inhibitors such as lithium chromate, lithium molybdate and lithium nitrate in a concentration of 5 ppm, have been evaluated at different ...

Electro‐Organic Synthesis at a Stable Oil/Water/Solid Three‐Phase Interface Reactor

open access: yesAngewandte Chemie International Edition, EarlyView.
A porous membrane electrode (PME) reactor is developed to promote oil/water/solid three‐phase interfacial contact for electro‐organic synthesis. By promoting the formation of an oil/water interfacial region within or near an amphiphilic catalytic layer, the reactor enables efficient conversion of water‐insoluble organic reactants in aqueous ...
