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.

As early as sixty years ago, zinc sulphide was first thought of as a pigment for coloring India rubber and a patent for the process of its manufacture was issued in England. But it was not until twenty years later that zinc sulphide and its manufacture was seriously considered as a pigment for paint, and in 1874 a patent was issued for a process of manufacturing a white pigment, composed of zinc sulphide and barium sulphate, known as Charlton white, also as Orr's white enamel. This was followed in 1876 by a patent issued to a manufacturer named Griffith and the product, which was similar in character to Charlton white, was known as Griffith's patent zinc white. In 1879 another patent for a more novel process was obtained by Griffith & Cawley, the product made under this process proving the best of the series placed upon the market up to that date. After that time many new processes were patented, all, however, tending to the same object, that of producing a white pigment, composed of zinc sulphide and barium carbonate, the results, however, in many cases ending with failure.
On the other hand, the U.S. Food and Drug Administration (FDA) in their Final Administrative Order on Sunscreen Drug Products posted in September 2021 still accepts titanium dioxide up to 25% in the list of Generally Recognized As Safe and Effective (GRASE) in the main document, without further clarification on what kind or size of particles [9]. However, on page 24 (Sunscreen containing nanomaterials) FDA clearly “distinguish nanomaterials from other forms of these ingredients'' (zinc oxide and titanium dioxide) and ask for comments on “any particular nanomaterials that you believe should not be permitted for use in OTC sunscreen products”. To the best of our knowledge, this Agency did not ban the use of nanoparticulate titanium dioxide in any form, even though it is mentioned on page 34 that the anatase form is the more photoactive one, due to the lack of evidence with real sunscreens OTC (over the counter) in vivo. Moreover, other regulations in Latin America (MERCOSUR agreement, 2006) do not state clearly their position on the use of nanoparticulate TiO2NPs [10].
The self-drilling aspect of these screws implies that they come equipped with a sharp, drill-like tip that enables them to pierce through materials without the need for pre-drilling a pilot hole. This feature significantly speeds up the installation process and reduces the risk of damaging the material being used. Self-drilling screws are often made from durable materials, such as stainless steel or carbon steel, and are coated with various finishes to enhance corrosion resistance and longevity.
Conclusion
1. Metal Roofing Their self-drilling nature makes them ideal for attaching metal roofing panels to structures quickly and securely. They ensure a tight seal, which is critical for preventing leaks.

When selecting hex screws for your woodworking project, consider factors such as the type of wood you’ll be using, the required strength of the connection, and whether the screws will be exposed to moisture or outdoor elements. For example, if you are working with pressure-treated lumber outdoors, opting for stainless steel hex screws will prevent rust and ensure longevity.
Additionally, the capability for tool-less installation means that these screws can be utilized in tight spaces where conventional tools may not fit. This flexibility is crucial in various applications, especially in the automotive and electronics industries, where components are often placed in confined areas.
4. Corrosion Resistance The black phosphate coating not only provides a sleek finish but also protects the screws from rust and corrosion. This is crucial in regions with high humidity or in applications where moisture may be a concern, ensuring that the integrity of the assembly remains intact over time.
