The timing belt is made of durable rubber reinforced with materials such as fiberglass or steel to withstand the high temperatures and intense pressures found in an engine. Unlike the serpentine belt, which drives several accessories such as the alternator and power steering pump, the timing belt is a critical part of the engine’s design and function. It typically has teeth or ribs that mesh with the gears on the crankshaft and camshaft, providing a secure grip that prevents slippage.

  • This article discusses the discovery of phosphorescent lithopone on watercolor drawings by American artist John La Farge dated between 1890 and 1905 and the history of lithopone in the pigment industry in the late 19th and early 20th centuries. Despite having many desirable qualities for use in white watercolor or oil paints, the development of lithopone as an artists’ pigment was hampered by its tendency to darken in sunlight. Its availability to, and adoption by, artists remain unclear, as colormen's trade catalogs were generally not explicit in describing white pigments as containing lithopone. Further, lithopone may be mistaken for lead white during visual examination and its short-lived phosphorescence can be easily missed by the uninformed observer. Phosphorescent lithopone has been documented on only one other work-to-date: a watercolor by Van Gogh. In addition to the history of lithopone's manufacture, the article details the mechanism for its phosphorescence and its identification aided by Raman spectroscopy and spectrofluorimetry.

  • Titanium Dioxide Rutile Tio2 POWDER Titanio Dioxide Pigment

  • Because of its ability to absorb UV light, it's particularly useful as an ingredient in sunscreens — while its light-scattering properties are great for applications that require white opacity and brightness, such as in paint and paper.
