There are several different types of foundation bolts, each designed for specific applications. For example, J-bolts are commonly used to secure columns and beams to a concrete foundation, while U-bolts are often used to anchor equipment or machinery to the ground For example, J-bolts are commonly used to secure columns and beams to a concrete foundation, while U-bolts are often used to anchor equipment or machinery to the ground
The basic scenario of resistive switching in TiO2 (Jameson et al., 2007) assumes the formation and electromigration of oxygen vacancies between the electrodes (Baiatu et al., 1990), so that the distribution of concomitant n-type conductivity (Janotti et al., 2010) across the volume can eventually be controlled by an external electric bias, as schematically shown in Figure 1B. Direct observations with transmission electron microscopy (TEM) revealed more complex electroforming processes in TiO2 thin films. In one of the studies, a continuous Pt filament between the electrodes was observed in a planar Pt/TiO2/Pt memristor (Jang et al., 2016). As illustrated in Figure 1C, the corresponding switching mechanism was suggested as the formation of a conductive nanofilament with a high concentration of ionized oxygen vacancies and correspondingly reduced Ti3+ ions. These ions induce detachment and migration of Pt atoms from the electrode via strong metal–support interactions (Tauster, 1987). Another TEM investigation of a conductive TiO2 nanofilament revealed it to be a Magnéli phase TinO2n−1 (Kwon et al., 2010). Supposedly, its formation results from an increase in the concentrations of oxygen vacancies within a local nanoregion above their thermodynamically stable limit. This scenario is schematically shown in Figure 1D. Other hypothesized point defect mechanisms involve a contribution of cation and anion interstitials, although their behavior has been studied more in tantalum oxide (Wedig et al., 2015; Kumar et al., 2016). The plausible origins and mechanisms of memristive switching have been comprehensively reviewed in topical publications devoted to metal oxide memristors (Yang et al., 2008; Waser et al., 2009; Ielmini, 2016) as well as TiO2 (Jeong et al., 2011; Szot et al., 2011; Acharyya et al., 2014). The resistive switching mechanisms in memristive materials are regularly revisited and updated in the themed review publications (Sun et al., 2019; Wang et al., 2020).
- The global market for Anatase and Rutile suppliers is diverse and competitive. Leading suppliers are dedicated to delivering consistent quality and meeting the specific requirements of their clients. They invest heavily in research and development to improve the purity and performance of their products while ensuring sustainable sourcing and production practices.
- The mining and extraction of titanium ore are usually carried out in mineral-rich areas where titanium deposits are found. The extracted ore is then purified using various chemical processes to remove impurities and obtain pure titanium dioxide. Once the titanium dioxide is obtained, it is milled and processed to produce the final pigment in the desired form, such as powder or slurry.

EFSA's evaluation is related to the risks of TiO2 used as a food additive, not to other uses.

A 2023 study published in the journal Environmental Research, scientists examined the effect of titanium dioxide nanoparticles on important gut bacteria in mice. Their results showed “the growth inhibitory effects could be associated with cell membrane damage caused by titanium dioxide nanoparticles to the bacterial strains. Metabolomics analysis showed that TiO2 NPs caused alterations in multiple metabolic pathways of gut bacteria, such as tryptophan and arginine metabolism, which were demonstrated to play crucial roles in regulating gut and host health.” The researchers also found that four different neuroprotective metabolites “were significantly reduced” in urine and in vitro bacteria and vivo urine samples. The researchers concluded: “Increasing evidence implies that the gut microbiome plays a profound role in regulating host metabolism. Our results illustrated that TiO2 NPs hindered the growth of four beneficial gut bacterial strains.”
Titanium dioxide has many purposes in both food and product development.

How do I know if a Unilever product contains titanium dioxide?
In addition to hiding power, titanium dioxide also plays a vital role in enhancing the durability of paints. It acts as a barrier, protecting the walls from external elements such as UV radiation, moisture and pollutants. Titanium dioxide's high refractive index allows it to reflect harmful UV rays, preventing them from fading paint and retaining its vibrant colors for a long time. This UV resistance is especially important for facades that are exposed to sunlight throughout the day.
