Moreover, the use of homeopathy in cattle management aligns with organic and biodynamic farming practices that emphasize natural methods for maintaining health. Organic farming standards often limit the use of conventional drugs, and homeopathy provides a viable alternative. Farmers utilizing homeopathic methods report not only improved health outcomes in their cattle but also a decrease in the overall incidence of diseases, leading to reduced veterinary costs in the long run.

Respiratory diseases in poultry are a significant concern within the avian industry, affecting not only the health and welfare of the birds but also posing economic implications for poultry farmers. The respiratory system of birds is complex and can be susceptible to various pathogens, including viruses, bacteria, and fungi. The understanding and management of respiratory diseases are crucial for maintaining flock health and ensuring the productivity of poultry operations.

  • The determination of sulphate in titanium dioxide (TiO2) is a crucial process for manufacturers to ensure the quality and purity of their products. Sulphate, if present in significant amounts, can affect the performance and color of TiO2, leading to potential issues in various applications such as coatings, plastics, and cosmetics. Therefore, accurate and reliable methods for detecting sulphate are essential for manufacturers to maintain high standards of product quality.
  • 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).

  • Although the evidence for general toxic effects was not conclusive, on the basis of the new data and strengthened methods our scientists could not rule out a concern for genotoxicity and consequently they could not establish a safe level for daily intake of TiO2 as a food additive.

  • FAQ – EFSA 2021 safety assessment of titanium dioxide (E171)

  • In the manufacturing industry, titanium dioxide is primarily used as a pigment in the production of paints, coatings, and plastics. Its white color and excellent hiding power make it an ideal choice for these applications. The chemical inertness and high refractive index of titanium dioxide also contribute to its popularity in the manufacturing sector.
  • Titanium dioxide used for adhesive applications should contain an inorganic coating to control polarity, improve its ease of dispersion, and improve its weather resistance. The inorganic coating (zirconium dioxide, silica, alumina) is applied in the aqueous slurry by precipitation of one or more hydrated metal oxides and by neutralization of acidic and alkaline compounds.

  • Titanium dioxide particles help light scatter and reflect, Kelly Johnson-Arbor, MD, a medical toxicology physician at the National Capital Poison Center, told Health. Because of that, we often use it as a whitening agent.

  • No. EFSA’s role was limited to evaluating the risks linked to titanium dioxide as a food additive. This included an assessment of relevant scientific information on TiO2, its potential toxicity, and estimates of human dietary exposure. Any legislative or regulatory decisions on the authorisations of food additives are the responsibility of the risk managers (i.e. European Commission and Member States).
