The aim of this work was to examine particularly the Degussa P25 titanium dioxide nanoparticles (P25TiO2NPs) because they are among the most employed ones in cosmetics. In fact, all kinds of titanium dioxide nanoparticles (TiO2NPs) have gained widespread commercialization over recent decades. This white pigment (TiO2NPs) is used in a broad range of applications, including food, personal care products (toothpaste, lotions, sunscreens, face creams), drugs, plastics, ceramics, and paints. The original source is abundant in Earth as a chemically inert amphoteric oxide, which is thermally stable, corrosion-resistant, and water-insoluble. This oxide is found in three different forms: rutile (the most stable and substantial form), brookite (rhombohedral), and anatase (tetragonal as rutile), of these, both rutile and anatase are of significant commercial importance in a wide range of applications [3]. Additionally, the nano-sized oxide exhibits interesting physical properties, one of them is the ability to act as semiconducting material under UV exposure. In fact, TiO2NPs are the most well-known and useful photocatalytic material, because of their relatively low price and photo-stability [4]. Although, this photoactivity could also cause undesired molecular damage in biological tissues and needs to be urgently assessed, due to their worldwide use. However, not all nanosized titanium dioxide have the same behavior. In 2007, Rampaul A and Parkin I questioned: “whether the anatase/rutile crystal form of titanium dioxide with an organosilane or dimethicone coat, a common titania type identified in sunscreens, is appropriate to use in sunscreen lotions” [5]. They also suggested that with further study, other types of functionalized titanium dioxide could potentially be safer alternatives. Later, Damiani found that the anatase form of TiO2NPs was the more photoactive one, and stated that it should be avoided for sunscreen formulations, in agreement with Barker and Branch (2008) [6,7].

  • One of the key benefits of metal cased oil seals is their durability and resistance to high temperatures and pressures. The metal casing provides a strong barrier against wear and tear, ensuring that the seal remains intact even in demanding operating conditions. This makes them ideal for use in heavy-duty applications where reliability is paramount.

  • When it comes to choosing new spark plugs for your car, it is important to consider both cost and quality. While cheaper spark plugs may seem like a more cost-effective option upfront, they may end up costing you more in the long run if they need to be replaced more frequently. Investing in high-quality spark plugs made of premium materials can help improve your car's performance and fuel efficiency, ultimately saving you money in the long term.


  • The applications for the small rubber gasket are as varied as the industries it serves. Within the confines of an automobile's engine, it ensures the proper functioning of the cooling system by sealing hoses and connection points. In buildings, it forms a crucial defense against water infiltration around windows and doors. Even in the meticulous environment of a cleanroom, small rubber gaskets secure filter housings, protecting against contaminants.
  • 2. Remove the Old Gasket Carefully remove the old valve cover gasket by prying it off with a flat-head screwdriver or similar tool. Be sure to avoid damaging the valve cover or surrounding components during this process.
  • Place the mounting sleeve with the PTFE oil seal on the shaft.

  • The consequences of a blown head gasket can be severe
  • The valve cover gasket seals the gap between the cylinder head and the valve cover, preventing oil leaks that could compromise efficiency and potentially lead to severe damage. It is held in place by a set of bolts, which not only secure the gasket but also maintain the necessary pressure for a leak-free seal.
