Although barium sulfate is almost completely inert, zinc sulfide degrades upon exposure to UV light, leading to darkening of the pigment. The severity of this UV reaction is dependent on a combination of two factors; how much zinc sulfide makes up the pigments formulation, and its total accumulated UV exposure. Depending on these factors the pigment itself can vary in shade over time, ranging from pure white all the way to grey or even black. To suppress this effect, a dopant may be used, such as a small amount of cobalt salts, which would be added to the formulation. This process creates cobalt-doped zinc sulfide. The cobalt salts help to stabilize zinc sulfide so it will not have as severe a reaction to UV exposure.

Titanium dioxide production begins with the extraction of raw materials, typically ilmenite or rutile, from mines. In a white titanium dioxide factory, these minerals undergo a rigorous refining process that includes steps like sulfuric acid digestion, chloride process, or sulfate process, depending on the factory's technology and resources. The resulting titanium dioxide pigment is then purified, dried, and ground to achieve the desired particle size and quality.

  • For a review published in 2023 in the journal Environmental Pollution, researchers examined E171 as a possible factor promoting obesity-related metabolic disorders. Because gut microbiota play an important role in immune function maintenance and development, and because titanium dioxide as a food additive has been shown to alter gut microbiota, researchers wanted to review “the dysregulations along the gut microbiota-immune system axis after oral TiO2 exposure compared to those reported in obese or diabetic patients, and to highlight potential mechanisms by which foodborne TiO2 nanoparticles may increase the susceptibility to develop obesity-related metabolic disorders.” The study authors discovered recurrent changes in the gut microbiota composition when exposed to titanium dioxide nanoparticles, with an imbalance of intestinal symbiotic microbiota. These changes and imbalances were also reported and played a role in the development of obesity, the authors wrote. This highlights “foodborne TiO2 nanoparticles as an endocrine disruptor-like chemical promoting obesity-related disorders,” the authors concluded.

  • The wedge type gate valve features a unique design characterized by a tapered wedge disc that is positioned between two parallel seats within the valve body. The valve operates by lifting or lowering the wedge disc through the use of a threaded stem and handwheel or actuator. When the disc is raised, the flow path is opened, allowing fluid to pass. Conversely, lowering the disc closes the valve, establishing a tight seal against the seats.


  • Safety is another key consideration for anyone transporting bikes. Trunk bike carriers are designed to secure the bicycles firmly in place, minimizing movement while driving. Many models also feature additional straps and padding to protect both the bicycles and the vehicle's paintwork from scratches. It is crucial, however, for users to regularly check that their bikes are properly secured before embarking on longer trips. Ensuring that the carrier is in good condition and that all attachment points are secure can prevent accidents and damage while on the road.
