In addition to its lightweight nature, FRP mesh grating boasts impressive durability and longevity. It is engineered to withstand harsh environmental conditions, including exposure to chemicals, UV radiation, and extreme temperatures. This makes it particularly useful in industries such as wastewater treatment, petrochemicals, and food processing, where materials are frequently subjected to corrosive substances and rigorous cleaning processes. Unlike metal gratings that may corrode over time, FRP maintains its structural integrity, reducing the need for frequent replacements and maintenance.

Another vital advantage is the high specific strength of FRP materials. This means that, even though they are lighter, they can support substantial loads, making them ideal for reinforcing existing structures or using in new constructions where weight is a critical factor. This characteristic enables engineers to explore designs that are both aesthetically pleasing and structurally sound.

2. Corrosion Resistance FRP materials are inherently resistant to corrosion caused by environmental factors and chemicals, making them ideal for use in areas prone to moisture, salt spray, or industrial chemicals. This characteristic significantly extends the lifespan of the panels without the need for frequent replacements.

The morphology of vitaminB2@P25TiO2NPs is coherent with the description of Degussa P25 typical population. Size distribution histograms were made from manual measures of the nanoparticles observed in SEM micrographs using ImageJ®. This data showed that more than 70% is anatase (between 20 and 60 nm) with a minor amount of rutile characteristic bars (between 80 and 100 nm) and a small amount of amorphous phase (<40 nm) [36]. Further analysis of the same sample areas with an EDS probe demonstrated the presence of organic material composed of C and O (Fig. 2). This material was found homogeneously distributed on the surface of the different shapes of P25TiO2NP, not in the background, indicating a specific interaction that could be attributed to the functionalization of the P25TiO2NPs with vitamin B2.
Not everyone agrees, though. The European Commission banned titanium dioxide as a food additive in the European Union in 2022.
When E171 is part of a food product, it passes through the digestive system without causing harm because E171 combines with the other ingredients.

Following a request for assessment in 2020 by the EU, the European Food Safety Authority (EFSA) assessed E171, particularly for its genotoxicity. In 2022, the agency deemed the food additive no longer safe for use.
Food-grade titanium dioxide differs from what’s added to plastics and paints to enhance whiteness. However, there have been concerns about the environmental impact of titanium dioxide production and the potential health risks from exposure to its particles.
But despite all these cries of alarm, five years on from the original study no further testing into the safety of Titanium Dioxide in our food supply
Variations of titanium dioxide are added to enhance the whiteness of paint, plastics, and paper products, though these variations differ from the food-grade ones for things we eat (1Trusted Source, 2Trusted Source).

A few non-dietary studies have reported adverse effects in the gastrointestinal tract of laboratory animals given food-grade TiO2. However, these same effects were not seen when the same or higher doses of food-grade TiO2 were administered in the animals' diet. Dietary studies best reflect how humans are exposed to TiO2 from food. Thus, the Food Directorate placed the most emphasis on the results of these studies in the state of the science report.
