“…Only works with precise control over the shape and surface structure of catalysts are included, so that the NN can be input with the exact coordination information and that its experimental accuracy can be evaluated with regard to coordination effect. Previous studies [49][50][51][52][53] succeeded in synthesizing two categories of shapes: cube and octahedron. Cubes expose a high ratio of (100) surfaces while octahedral expose (111) surfaces predominantly, both of which were verified with electron microscopy techniques in the respective works.…”

“…For instance, strain effect has also been shown to affect the activity. 54,55 Strain effect is less of a concern for well-matched lattices, as in the case of bimetallic and HEA studied here, but could be more pronounced for atoms Measured ORR Specific Activity Activity measurements were collected from prior studies, all performed at 0.9 V versus reversible hydrogen electrode, with 0.1 M HClO 4 , and at room temperature works (Rh-Pd, 49 Pt-Ir, 50 Pd-Pt, 51,52 Pd-Ir, 53 and Pt 50,51 ). Most referenced studies utilized precise shape-controlled synthesis and therefore enable comparison of coordination effect.…”

“…Regarding new compositions or alloys with new structures and properties, the trend is to involve more elements that are capable of inducing more functionality, even with the addition of small quantities. Frequently, such elements are rare elements, such as cerium, yttrium, or lanthanide, which are inducing remarkable mechanical properties and stability at elevated temperatures [74][75][76].…”

Starting with a description of the meaning of sustainable coating nowadays, this review presents a selection of methods for sustainable coatings manufacture using raw materials, saving energy and costs. This selection creates an introduction for the coatings performances of intensively investigated coated alloys and their multifunctionality. There are many examples and EU recommendations to be discussed, and we especially chose to introduce sustainable coatings with both industrial and medical functions, such as bioinspired films and coatings on high-entropy alloys, biodegradable metallic alloys, etc. A special focus is on nanotechnology and nanomaterials in green procedures, enhancing coatings’ multifunctionality, introducing green corrosion inhibitors, smart additives, and coatings based on superhydrophobicity. The conclusions and future perspectives of sustainable and multifunctional coatings, as expressions of sustainable advanced materials, are based on important motivations of such studies.

“…Rare-earth elements (REEs) are characterized by unique optical (Cho and Chen, 2020), magnetic (He et al, 2022), and catalytic properties (Kim et al, 2021) and are known as "industrial vitamins." These materials are used widely in various fields such as chemical engineering and metallurgy, and also are used for the fabrication of specific materials.…”

Paper-based LRET sensor for the detection of total heavy rare-earth ions

et al. 2022

Based on the mechanism of luminescence resonance energy transfer (LRET) and using a special single strand DNA as the recognition element, a portable paper-based sensor for the accurate detection of total heavy rare-earth ions (mainly Gd3+, Tb3+ and Dy3+) concentration was proposed. The RNA cleaving-DNAzyme should recognize rare-earth ions to cleave RNA on DNA duplexes linking UCNPs and AuNPs, causing UCNPs and AuNPs to approach each other, inducing LRET, which attenuated the green upconversion luminescence (UCL) triggered by the 980 nm laser. UCL was captured by a charge-coupled device (CCD) image sensor and processed with the red-green-blue (RGB) image to quantitatively analyze heavy rare-earth ions in the samples. In the range of 5–50 μmol·L-1, the sensor has good sensitivity, with the limit of detection of 1.26 μmol L−1.
