While IARC listed titanium dioxide as “possibly carcinogenic to humans,” they also add that “there is inadequate evidence in humans for the carcinogenicity of titanium dioxide.” Of the four human studies that they reviewed, only one showed a potential risk for occupational workers inhaling titanium dioxide particles and lung cancer, while the other three showed no risk for cancer at all. And it’s key to note that IARC did not assess the effects of titanium dioxide found in foods.

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.

The properties of lithopone are very suitable for use in the production of coatings. Because the ingredients of lithopone are zinc sulfide and barium sulfate, and the more zinc sulfide content, the stronger its covering power. This indicates a paint product with strong white covering power. It is different from water in that it reacts with acid but does not react with alkali. It has a wide range of uses. Because its structural properties are similar to titanium dioxide and its price is relatively cheap, it can also be used as a substitute for some titanium dioxide. Lithopone can be used for coloring paints, inks, pigments, rubber, paper, leather, enamel, etc.

Both P25TiO2NPs (with or without vitamin B2) were not found beyond the epidermis in 99% of the analyzed TEM images (Fig. 8). This is coherent with previous findings showing that nanoparticles greater than 50 nm can not penetrate the skin, even in vivo models with movement, stretching, and friction [54]. However, in one of the zones, a few nanoparticles were observed inside a hair follicle. This could be due to the follicle exposure after the localized rupture of this physical barrier when rats were shaved in order to clean the area for cream topical administration. This finding suggests that nanoparticle-based sunscreen should not be applied on recently shaved or harmed skin, in order to avoid nanoparticle skin penetration.

  • What is an Overlock Sewing Machine?


  • Sustainability is another important aspect of the modern chain stitch machine. By enabling fast production with minimal waste, manufacturers can align with eco-friendly practices that are becoming increasingly important in today’s market. Efficient use of materials and the ability to quickly adapt to changing consumer demands allows companies to reduce their environmental footprint while still delivering high-quality products.


  • Additionally, these machines often come with multi-needle capabilities. This feature allows for the use of different thread colors and types without the need for constant rethreading, significantly reducing production time. High-speed operation is another hallmark of industrial zig zag machines, with some capable of producing thousands of stitches per minute, which drastically increases output.


  • The backstitch is a fundamental sewing technique that serves to secure the start and end of a seam. Traditionally, this process required the sewist to manually reverse the stitching at both ends of a seam, which could be tedious and time-consuming. With the advent of sewing machines equipped with an automatic backstitch feature, this tedious step has been streamlined. The machine automatically stitches backward for a few stitches, locking the seam in place without any manual intervention.


  • When it comes to sewing, the right tools can make all the difference. One of the most essential tools in any sewing enthusiast's arsenal is the sewing machine needle. Among the various options available, chrome sewing machine needles stand out for their durability, smoothness, and versatility. In this article, we will explore what chrome sewing machine needles are, their benefits, the different types available, and how to care for them to prolong their lifespan.


  • Moreover, with the rise of sustainability in fashion, automatic button sewing machines can play a significant role. By enhancing efficiency and reducing waste, they allow businesses to operate more sustainably. For instance, fewer mistakes in button placement mean less fabric scrapping and reduced resource consumption overall. This aligns with the growing consumer demand for eco-friendly production practices, ultimately benefiting the environment.


  • The thread is an often-overlooked component in the sewing process. However, it is crucial, especially when dealing with light fabrics. Heavy-duty machines are designed to handle thicker threads used for robust materials, but using such threads on delicate fabrics can result in puckering or even tearing.

  • Another advantage of HD sewing machines is their high-speed stitching capabilities. These machines can stitch at a much faster rate than traditional sewing machines, allowing users to complete projects in a fraction of the time. This increased efficiency makes HD sewing machines ideal for professionals who need to complete multiple projects quickly, as well as hobbyists who want to spend less time sewing and more time creating.
  • One of the key advantages of using a hand-held bag closer sewing machine is its versatility. These machines can be used to sew a wide range of materials, including burlap, jute, cotton, and polypropylene. Whether you need to sew a small paper bag or a large burlap sack, a hand-held bag closer sewing machine can handle the job with ease.

  • Furthermore, single needle sewing is versatile and can be used on a wide range of fabricssingle
  • Invented by Elias Howe in 1846, the single lockstitch machine was the first successful sewing machine design, predating the more familiar Singer model. It operates on a principle that involves two threads - one from the needle and another from the bobbin - interlocking to create a secure stitch. The needle thread passes through the fabric, forming a loop, which the bobbin thread then catches, creating the characteristic 'lock' in the stitch. This process not only speeds up sewing but also ensures durability and strength in the final product.
