The conventional surface treatment methods of titanium alloy include glow discharge plasma deposition, oxygen ion implantation, hydrogen peroxide treatment, thermal oxidation, sol-gel method, anodic oxidation, microarc oxidation, laser alloying, and pulsed laser deposition. These methods have different characteristics and are applied in different fields. Glow discharge plasma deposition can get a clean surface, and the thickness of the oxide film obtained is 2 nm to 150 nm [28]. The oxide film obtained from oxygen ion implantation is thicker, about several microns [914]. Hydrogen peroxide treatment of titanium alloy surface is a process of chemical dissolution and oxidation [1516]. The dense part of the oxide film is less than 5 nm [1721]. The oxide film generated from the thermal oxidation method has a porous structure, and its thickness is commonly about 10-20 μm [2225]. The oxide film from the sol-gel method is rich in Ti-OH, a composition that could induce apatite nucleation and improve the combining of implants and bone. It has a thickness of less than 10 μm [2628]. Applied with the anodic oxidation method, the surface can generate a porous oxide film of 10 μm to 20 μm thickness [2931]. Similarly, the oxide film generated from the microarc oxidation method is also porous and has a thickness of 10 μm to 20 μm [3233].

It’s true that titanium dioxide does not rank as high for UVA protection as zinc oxide, it ends up being a small difference (think about it like being 10 years old versus 10 years and 3 months old). This is not easily understood in terms of other factors affecting how sunscreen actives perform (such as the base formula), so many, including some dermatologists, assume that zinc oxide is superior to titanium dioxide for UVA protection. When carefully formulated, titanium dioxide provides excellent UVA protection. Its UVA protection peak is lower than that of zinc oxide, but both continue to provide protection throughout the UVA range for the same amount of time.

Traditionally, UV-filters are categorized as either chemical or physical. The big difference is supposed to be that chemical agents absorb UV-light while physical agents reflect it like a bunch of mini umbrellas on top of the skin. While this categorization is easy and logical it turns out it's not true. A recent, 2016 study shows that inorganic sunscreens work mostly by absorption, just like chemical filters, and only a little bit by reflection (they do reflect the light in the visible spectrum, but mostly absorb in the UV spectrum).

The pricing of these lithopones varies depending on several factors such as raw material costs, production processes, and market demand. As global markets fluctuate, so too does the cost of lithopone, with suppliers often adjusting their price lists to reflect these changes. This dynamic nature of pricing requires buyers to stay informed and adaptable, seeking out not only competitive rates but also assurances of consistent product quality.

The vitaminC@P25TiO2NPs, on the other hand, were obtained through an optimized method based on Mallakpour et al. [27]. Initially, 0.02 g of P25TiO2NPs were dispersed in 1 mL of ultrapure water and stirred in a Vortex. Next, 100 μL of HCl (0.01 M) were added (pH 2) to 100 uL of P25TiO2NPs to avoid gel formation. Then, 100 μL of vitamin C dissolved in ultra-pure water (5.0 × 10−3 M) solution were added to the mixture and was ultrasonicated for 30 min. Finally, vitamin C was added in excess to gain a beige-orange color suspension, and the ultrasonication continued for another 30 min. The pellet obtained after centrifuging the suspension for 10 min at 4500 rpm was resuspended in ultrapure water, centrifuged again, and then lyophilized.

  • Odporność na warunki atmosferyczne to kolejna istotna zaleta aluminiowych krat. Aluminium naturalnie tworzy warstwę tlenku, która chroni je przed korozją, co czyni je idealnym materiałem do zastosowania na zewnątrz. Kratki aluminiowe są często wykorzystywane w budowie chodników, tarasów, a także w obiektach przemysłowych, gdzie narażone są na działanie chemikaliów i zmiennych warunków atmosferycznych.


  • Galvanised steel grating is a versatile and durable material widely used in various industrial and commercial applications. This type of grating is made from steel bars that are welded together to form a grid-like pattern, providing a strong and lightweight structure. The galvanisation process involves coating the steel with a layer of zinc to protect it from corrosion, which significantly enhances its longevity and performance, especially in harsh environments.
