Abstract of Bismuth Oxide Powder
The use of various spectroscopic techniques to study the properties of bismuth oxide nanoparticles. These included energy-dispersive-X-ray spectroscopy diffuse reflection spectroscopy Fourier transform infrared spectroscopy UV-visible spectrophotometer. The size, morphology, and UV-protection characteristics of nanoparticles of bismuth oxide were studied.
Bismuth oxide nanoparticles were produced by green process of synthesis. The process was performed with Mentha pulegium extract. This method of green synthesis has gained a lot attention in recent years. There is huge potential for this technique for the pharmaceutical and cosmetic industries.
Bismuth oxide nanoparticles had absorption peaks within the 200-400 nm range. This was due to the formation of a bismuth oxide polymorph. Bismuth oxide nanoparticles also exhibited UV blocking capability. The nanoparticles were also antibacterial.
Bismuth oxide powder was made using a straightforward combustion technique. The powder was then dried under vacuum. The surface morphology was evaluated by FE SEM. The atomic quantity of bismuth oxide powder was 2.7 (eV).
The time required for calcination of superfine bismuth oxides of high purity took 612 days. The temperature for calcination ranged between 450 and 600°C. The particle sizes of the powders range that range from 0.1-0.5 mm.
The band gap energy of bismuth oxide powder was measured by plotting the UV-DRS spectrum. Energy band gap of bismuth oxide is 2.7 (eV).
Bismuth oxide nanoparticles showed antibacterial activity against Gram-negative and Gram-positive bacteria. The UV protective properties were determined using diffuse reflection. The ideal time for the synthesis of nanoparticles also was determined by UV-Visible spectrum spectrophotometers as well as Fourier shift infrared spectrum.
Bismuth oxide nanoparticles possess excellent dispersibility. The UV protective characteristics of bismuth oxide nanoparticles are due to the dynamic light scattering capability which the nanoparticles possess. The bismuth powder has great purity and good dispersibility, which is suitable for use in electronic manufacturing.
Synthesis of Bismuth Oxide Powder
Numerous methods have been applied to make bismuth oxide powder. The hydrothermal method is just one of them. It produces powders that have excellent crystalline quality.
The method of spray pyrolysis is yet another method of synthesizing bismuth oxide powder. It is used in various applications such as gas sensing. Electrospinning also has been utilized to make the production of nanofibers. Sol-gel is another method that produces powders with a an extremely narrow pore distribution.
The mineral distributions of bismuth were observed by scan electron microscope. A crystallized structure was confirmed using X-ray difraction. Different spectroscopic techniques like dynamic light scattering, FTIR, XRD and UV-Visible spectroscopy were used to characterize the samples.
The UV-visible absorption spectrum was studied in order to evaluate the UV protective properties of nanoparticles. The wavelength of absorption for UV ranges from 250 to 700 nanometers. The absorption peak for bismuth is at 300 nm.
The antibacterial property of nanoparticles also was studied using disk diffusion. The antibacterial power of bismuth oxide was evaluated in comparison to salmonella ATCC 1231. It was stained on the discs with different concentrations of samples. The radius of inhibition was measured with the ruler.
This green process for synthesising nanoparticles has attracted much attention in recent years. It has been used for diverse applications in the food industry and pharmaceutical industry.
Nanoparticles of bismuth oxide are also utilized for UV blocking. They are very pure and have antibacterial function. The photocatalyst of bismuth has broad absorption spectrum and has the capacity of removing organic molecules. It is also helpful to treat water.
applications of Bismuth Oxide Powder
One of the numerous uses for bismuth oxide powder is metal surface treatment products, plastics and coating products. The powder is also a vital role in chemical vapour deposition, thermal evaporation the electron beam process, and.
Bismuth oxide nanoparticles have also been examined as radiosensitizers. Radiosensitizers are able to enhance the effects radiation on cell viability. This results in damage to DNA of the cells.
Nanoparticles produced high surface area which can be used for target imaging. They also possess a high radiopacity. Bismuth oxide nanoparticles are integrated into a range of products, such as surgical devices, optical filters, and magnetic field detectors. They are also used for tracking the accumulation of bismuth.
Bismuth oxide nanowires that have good crystalline quality have been synthesized by inducing stress in low temperature. These materials were used as radiosensitizers in Megavolt or Kilovolt radiation therapy.
Nanostructured bismuth materials have attracted lots of attention due to the quantum behavior of the material. They are also utilized in power generators, thermoelectric coolers, and optical devices.
Bismuth oxide has also been proved to be effective on biological uses. Bismuth base medical formulations are often used to treat stomach issues. Bismuth is also used for astringents in addition to bacteriostatic compounds as well as refrigerants. The substance has also been used in the nuclear industry as refrigerant. It can also be used as a substitute for leads in electronic equipment.
Bismuth is used in various ways from the 19th century onward. But, the use of bismuth was reduced in the latter half of 20th century. It was due to the reversibility of bismuth encephalopathy. There are, however, some established treatments that require the latest technologies.
