[article]  inCOATINGS TECH > Vol. 17, N° 2 (02/2020) . - p. 24-25 Titre : Coatings participate in the superconducting realm Type de document : texte imprimé Année de publication : 2020 Article en page(s) : p. 24-25 Note générale : Bibliogr. Langues : Américain (ame) Catégories : Isolants électriques Polyimides Revêtements organiques Supraconducteurs organiques Index. décimale : 667.9 Revêtements et enduits Résumé : The ability of materials to conduct electricity is affected by temperature. When the temperature approaches absolute zero (–273°C), many materials—from metals to ceramics to carbon nanotubes—conduct electricity with no resistance, thus becoming superconductors. In these materials, electrons pair up and travel effortlessly, avoiding interactions with single electrons and other obstacles in circuits. Superconductors are attractive because they can be used to generate large magnetic fields, and superconducting magnets find use in everything from magnetic resonance imaging (MRI) machines to the detectors in supercolliders. The key challenge to their widespread use is the need to maintain the temperature at approximately –173°C (100 Kelvin) or lower, depending on the material. If a room-temperature superconductor could be identified, levitating trains and hoverboards could be possible. For many superconducting applications, coatings play a vital role. Electrically insulating coatings have been commonly used on superconducting wires. Newer insulating coatings, such as the ultra-thin polyimide coatings developed by scientists at the RIKEN Center for Life Science Technologies and Chiba University,1 can be as thin as 4 mm. This is more than 10 times thinner than the conventional insulation used for high-temperature superconducting wires. Wires with the new coating have a cross-section containing just 10% insulation, a fivefold reduction of conventional superconducting wires, and they exhibit double the magnetic strength. Reducing the ratio of insulation to conductor in the wire allows for more compact superconducting coils for use in next-generation medical and scientific devices.

Increasing the functionality of interior architectural coatings / Cynthia Challener in COATINGS TECH, Vol. 17, N° 2 (02/2020)  

[article]  inCOATINGS TECH > Vol. 17, N° 2 (02/2020) . - p. 35-38 Titre : Increasing the functionality of interior architectural coatings Type de document : texte imprimé Auteurs : Cynthia Challener, Auteur Année de publication : 2020 Article en page(s) : p. 35-38 Langues : Américain (ame) Catégories : Matériaux -- Propriétés fonctionnelles Revêtements décoratifs:Peinture décorative Revêtements intérieurs:Peinture intérieure Index. décimale : 667.9 Revêtements et enduits Résumé : Interior architectural coatings today do much more than hide blemishes in walls and ceilings. They often play a key role in the overall decorating scheme and are chosen in concert with furnishings and room accessories. In addition, consumers today expect these coatings to have minimal impact on the environment and have low odor while also offering a multitude of performance properties, from high hiding power to stain resistance. Increasingly, consumers also want interior architectural coatings to have advanced functionality, from biocidal properties to the ability to degrade harmful chemicals in the air. The growing demand for higher and more varied performance is occurring at a time when the market for these coatings is expanding. Driven by healthy construction sectors in mature economies and rising incomes in emerging markets, the value of the global interior architectural coatings segment is growing from $39.8 billion in 2018 at a CAGR of 6.4% and will, according to IMARC Group, reach $57.8 billion by 2024.

Liquid color measurement / Ralph Jan Wörheide in COATINGS TECH, Vol. 17, N° 2 (02/2020)  

[article]  inCOATINGS TECH > Vol. 17, N° 2 (02/2020) . - p. 41-48 Titre : Liquid color measurement : A new approach for color testing Type de document : texte imprimé Auteurs : Ralph Jan Wörheide, Auteur Année de publication : 2020 Article en page(s) : p. 41-48 Langues : Américain (ame) Catégories : Colorimétrie Essais (technologie) liquides Pigments Revêtements:Peinture Stabilité chimique Index. décimale : 535.6 Couleur Résumé : When it comes to color testing, there are many precise instruments, color correction software packages, automated spray machines, etc., in the marketplace. Colorimetry is a science of great importance to the paint industry, especially in meeting the high-quality standards of customers. However, the high scientific level and the precision of the instruments cannot compensate for the challenges presented, because conventional color testing takes place at the very end of the paint production process and requires a great deal of time due to the drying process. In addition, it has become state-of-the-art to correct colors instead of producing them in the required quality in the first run.
