Résumé–Cet article traite de la découverte de lithopone phosphorescent sur des dessins à l'aquarelle, datés entre 1890 et 1905, de l'artiste Américain John La Farge et de l'histoire du lithopone dans l'industrie des pigments à la fin du 19e et au début du 20e siècle. Malgré de nombreuses qualités souhaitables pour une utilisation en tant que blanc dans les aquarelles et les peintures à l'huile, le développement du lithopone comme pigment pour artistes a été compliqué de par sa tendance à noircir lorsqu'il est exposé au soleil. Sa disponibilité et son usage par les artistes demeurent incertains parce que les catalogues des marchands de couleurs n'étaient généralement pas explicites à indiquer si les pigments blancs contenaient du lithopone. De plus, lors d'un examen visuel, le lithopone peut être confondu avec le blanc de plomb et sa phosphorescence de courte durée peut facilement être ignorée par l'observateur non averti. À ce jour, le lithopone phosphorescent a seulement été documenté sur une autre œuvre: une aquarelle de Van Gogh. En plus de l'histoire de la fabrication du lithopone, cet article décrit le mécanisme de sa phosphorescence et son identification à l'aide de la spectroscopie Raman et de la spectrofluorimétrie.
- One of the primary benefits of using rock extension rods is their ability to access hard-to-reach areas within mines. By increasing the length of the tool, operators can drill deeper into rock faces or navigate tight spaces more effectively. This not only maximizes resource extraction but also reduces the need for additional excavation that could potentially compromise the stability of the mine.
- The physical vibrations produced by jackhammers can have lasting effects on the surrounding structures and ground, potentially causing cracks in walls and foundations. This collateral damage may necessitate additional repairs, adding unforeseen costs to the project. Furthermore, the dust and debris generated during the demolition process pose health risks to both workers and nearby communities, requiring rigorous dust control measures and protective gear.
- Despite their numerous advantages, the use of handheld rock drills is not without its challenges. Safety concerns, including vibration-related injuries and noise pollution, must be addressed through proper training and advanced designs that mitigate these risks. Additionally, the environmental impact of increased drilling activities must be carefully managed to ensure sustainability.
