The method of spray pyrolysis is a different method used in making bismuth oxide powder. It has been employed in many applications like gas sensing. The electrospinning technique has also been employed to create of nanofibers. The sol-gel method is another technique for making powders with pores that are narrow.
The mineral distributions of bismuth were observed using the scanner electron microscope. The crystal structure was confirmed by X-ray diffraction. Many spectroscopic methods, such as dynamic light scattering, FT-IR, XRD and UV-Visible spectroscopy were used to determine the samples.
The spectrum of absorption of UV-visible light was examined to determine the UV protection properties of the nanoparticles. The wavelength of absorption for UV ranges between 250 and 700 nanometers. The absorption peak for bismuth is at the wavelength of 290 nanometers.
The antibacterial property of nanoparticles also was studied using an approach to diffusion of disks. Bismuth's antibacterial properties oxide was assessed against the salmonella ATCC 1231. The discs were stained with different concentrations of samples. The width of the zone inhibition was determined by using a ruler.
This green process for synthesising nanoparticles has gained a lot of interest in recent time. It is used in different applications in the pharmaceutical and food industries.
Nanoparticles of Bismuth oxide can also be employed for UV blocking. They are extremely pure and can be used for antibacterial effects. The bismuth oxide photocatalyst has an extensive absorption spectrum and is capable of removing organic molecules. It also plays a role for water purification.
applications of Bismuth Oxide Powder
among the many applications of bismuth oxide powder are surface treatment, plastics and coatings. The powder plays a vital role in chemical vapour deposition, thermal evaporation in addition to electron beam devaporation.
Bismuth oxide nanoparticles have also been investigated as radiosensitizers. Radiosensitizers enhance the effects radiation on cell viability. This leads to the damage of DNA within cells.
Nanoparticles can produce high surface areas and are used to target image. These particles also show a excellent radiopacity. Bismuth oxide nanoparticles can be used in a variety of items, including lasers, surgical instruments along with magnetic field sensors. They can also be used for tracking bismuth accumulation.
Bismuth oxide nanowires having excellent crystal quality were synthesized through induced stress under low temperatures. They have been utilized as radiosensitizers Megavolt and Kilovolt treatment.
Nanostructured bismuth materials have attracted an increasing amount of interest due to the quantum properties of the material. They can also be useful in thermoelectric coolers, as well as optical devices.
Bismuth oxide has also been proven to be effective with biological use. Bismuth derivatives for medical use are frequently used to treat stomach problems. Bismuth is also used in astringents, bacteriostatics and refrigerants. It is also employed in nuclear industry as a refrigerant. It can also be used as a substitute for led in equipment for electrical use.
Bismuth was used for a wide range of purposes since the 19th century. However, the use of bismuth decreased during 20th century. This was due to reversible bismuth encephalopathy. But, there are many treatment options that require the development of new technologies.
