In a study published in the journal Environmental Toxicology and Pharmacology in 2020, researchers examined the effects of food additives titanium dioxide and silica on the intestinal tract by grouping and feeding mice three different food-grade particles — micro-TiO2, nano-TiO2, and nano-SiO2.  With all three groups, researchers observed changes in the gut microbiota, particularly mucus-associated bacteria. Furthermore, all three groups experienced inflammatory damage to the intestine, but the nano-TiO2 displayed the most pronounced changes. The researchers wrote: “Our results suggest that the toxic effects on the intestine were due to reduced intestinal mucus barrier function and an increase in metabolite lipopolysaccharides which activated the expression of inflammatory factors downstream. In mice exposed to nano-TiO2, the intestinal PKC/TLR4/NF-κB signaling pathway was activated. These findings will raise awareness of toxicities associated with the use of food-grade TiO2 and SiO2.”

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.

  • Rubber is also a popular choice due to its flexibility.
  • Figure 1
  • For example, silicone rubber gaskets excel in extreme temperatures, maintaining their flexibility in freezers and enduring the heat of ovens. Neoprene, on the other hand, boasts excellent chemical resistance, making it a favorite for applications requiring exposure to oils and other chemicals. EPDM is renowned for its weather resistance, standing up to the elements in outdoor applications such as roofing and automotive parts.
  • After cleaning, inspect the valve cover and cylinder head for any irregularities such as warping or damage that might affect the seal. Should everything look good, position the new gasket in place, aligning it precisely with the holes and contours of the cylinder head.

  • • SIM method to prevent the spring from falling off (integral molding of spring and rubber)

  • - Replace the gasket if it shows signs of wear or tear, or if it has lost its resiliency
  • A spring, the composition of which depends on the type
     

  • In conclusion, rubber valve cover gaskets and valve cover gasket sets are essential components in automotive engines, contributing to the efficiency, performance, and reliability of the engine. Understanding the significance of these gaskets and their proper maintenance and replacement is crucial for optimizing the performance and longevity of the engine.

  • To maximize the benefits of iridium, Iridium Spark Plug features a unique design that optimizes the metal's properties. The spark plug's center electrode is made from iridium, ensuring maximum durability and resistance to wear. The insulator, which comes into contact with the combustible gases, is made from a ceramic material that is both durable and resistant to heat.
  • The quality of the power steering oil seal is also a critical factor in its performance
  • Relatively less maintenance and cleaning are required. It makes mechanical seals cost-effective.
  • Energy savings
  • No.
  • This comprehensive guide will provide you with an overview of oil seal dimensions, including their importance, common types, and how to measure them. By the end of this article, you will have a solid understanding of oil seal dimensions and how to apply this knowledge in real-world scenarios.

  • In addition to their performance benefits, Mico spark plugs are also easy to install and maintain. With their user-friendly design, you can quickly replace your old spark plugs with Mico spark plugs without any hassle. Regular maintenance of your spark plugs, including cleaning and replacing them when necessary, will help ensure the continued efficiency of your vehicle's engine.


  • The global oil seal market is populated by numerous suppliers, each offering a diverse range of products tailored to specific applications. Leading oil seal suppliers, such as Freudenberg, Parker Hannifin, and SKF, have built their reputations on providing high-quality seals with exceptional durability and performance. Their products are designed to withstand extreme temperatures, pressures, and rotational speeds, ensuring optimal performance in even the most challenging environments.

  • Oil seal is an essential component in various machinery and equipment, designed to prevent the leakage of oil and other fluids. One of the most commonly used oil seals is the 30-50-10 oil seal, which is known for its durability and efficiency in sealing oil leaks.

  • A valve cover gasket, in general, serves as a barrier between the engine's cylinder head and the valve cover. In the case of the 2.0 TSI engine, its function is to prevent oil leaks, maintaining a clean and efficient workspace for the valves and other critical components. The 'T' in TSI stands for turbocharging, which means that these engines operate under significantly higher pressure and temperature compared to naturally aspirated engines. Thus, the gasket must be robust enough to withstand these extreme conditions.

  • Spark plug wires, also known as ignition wires or high-tension leads, are crucial components in the ignition system of internal combustion engines. These wires are responsible for transmitting the high-voltage electrical current from the ignition coil to the spark plugs, initiating the combustion process within the engine cylinders. High-quality spark plug wires are essential for ensuring efficient ignition, optimal engine performance, and reduced emissions, making them a critical component in the overall efficiency and environmental impact of the vehicle.
