The elements of the bismuth crystal were observed with the scan electron microscope. The crystal structure was verified by X-ray Diffraction. Many spectroscopic methods, such as dynamic light scattering, FT-IR, XRD and UV-Visible spectroscopy were used to characterize the samples.
The UV-visible absorption spectrum was examined to determine the UV protective properties of the nanoparticles. The UV absorption wavelength ranges between 250 and 700 nanometers. The absorption peak for bismuth oxide is at 290 nm.
The antibacterial capability of the nanoparticles was also studied using the method of disk diffusion. Bismuth's antibacterial capacity oxide was evaluated in comparison to salmonella ATCC 1231. The discs were stained with different concentrations of samples. The size of the zone of inhibition was determined using an instrument called a ruler.
The green synthesis of nanoparticles has attracted much attention in recent time. It has been employed for various applications in the pharmaceutical industry as well as the food industry.
Nanoparticles of Bismuth oxide can also be used to block UV light. They have high purity and are effective for antibacterial action. The bismuth photocatalyst features an extensive absorption spectrum and is capable of removing organic molecules. It is also useful to treat water.
Uses of Bismuth Oxide Powder
among the many applications of bismuth dioxide powder are surface treatment, plastics and coating products. The powder is also a important role in chemical vapor removal, thermal evaporation, in addition to electron beam devaporation.
Nanoparticles of bismuth oxide have been studied as radiosensitizers. Radiosensitizers boost the effect radiation on cell viability. This causes damage to DNA of the cells.
Nanoparticles are able to produce large surface areas that can be used to target image. These particles also show a high radiopacity. Bismuth oxide nanoparticles are used in a variety of devices, such as medical devices, optical filters magnet field sensors. They can also be used for tracking the accumulation of bismuth.
Bismuth oxide nanowires with good crystalline quality have been manufactured through the process of induced stress using low temperatures. These materials are used to create radiosensitizers used in Megavolt as well as Kilovolt radiation therapy.
Nanostructured bismuth compounds have gained lots of attention because of the quantum properties of this material. They can also be used in thermoelectric coolers and optical devices.
Bismuth oxide is also found to be effective for biological purposes. Bismuth based medical formulations are often used to treat stomach ailments. Bismuth can also be used in astringentsas well as bacteriostatic agents and refrigerants. It has also been utilized in nuclear industries as refrigerant. It also serves as substitute for Lead in the electrical industry.
Bismuth was used in a variety of applications from the 19th century onward. However, use of bismuth was reduced in late in the century of the 20th. It was due to the reversibility of bismuth encephalopathy. However, there are still many treatment options that require the development of new technologies.
