Resumo–Este artigo discute a descoberta de litopônio fosforescente em desenhos de aquarela do artista americano John La Farge datados de entre 1890 e 1905 e a história do litopônio na indústria de pigmento no final do século XIX e início do século XX. Apesar de ter muitas qualidades desejáveis para o uso em aquarela branca ou tintas a óleo, o desenvolvimento do litopônio como um pigmento de artistas foi prejudicado por sua tendência a se escurecer na luz solar. Sua disponibilidade para e uso por parte de artistas ainda não está clara, uma vez que os catálogos comerciais dos vendedores de tintas geralmente não eram explícitos na descrição de pigmentos brancos como algo que contém litopônio. Além disso, o litopônio pode ser confundido com o branco de chumbo durante o exame visual e sua fosforescência de curta duração pode ser facilmente perdida pelo observador desinformado. O litopônio fosforescente foi documentado em apenas um outro trabalho até hoje: uma aquarela de Van Gogh. Além da história da manufatura do litopônio, o artigo detalha o mecanismo para a sua fosforescência e sua identificação auxiliada pela espectroscopia de Raman e espectrofluorimetria.

  • The leading Chinese TiO2 exporter in value and quantity has been Sichuan Lomon, followed by Henan Billions and Gansu CNNC Huayuan. However, Sichuan Lomon exported a value of titanium dioxide by USD100,000,000 more than the second rank Henan Billions. Henan Billions, on the other hand, exported over USD70,000,000 more TiO2 than Gansu CNNC Huayuan. This demonstrates the huge monopole-like position of the newly merged company Henan Lomon, which can determine the market development for TiO2 in China nearly all alone.

  • One of the key benefits of rotary shaft oil seals is their ability to prolong the lifespan of equipment and machinery by preventing the entry of harmful particles and contaminants. This helps reduce maintenance costs and downtime, ultimately improving overall efficiency and performance.
  • In the high-performance engine world, every component plays a crucial role in delivering maximum power and efficiency. One such integral part is the spark plug wires, which serve as the lifeline between the ignition system and the spark plugs. These wires are responsible for transmitting the high voltage electrical current from the ignition coil to the spark plugs, igniting the air-fuel mixture and propelling the vehicle forward.

  • When selecting rubber valve cover gaskets, it is important to prioritize quality, durability, and compatibility with the specific vehicle model. High-quality gaskets should be designed to withstand the heat and pressure within the engine, providing a reliable and long-lasting seal. Choosing reputable suppliers and manufacturers known for producing high-quality rubber valve cover gaskets is crucial to ensure the reliability and longevity of these critical components.
