Abstract of Bismuth Oxide Powder
A variety of spectroscopic methods were used to determine the composition of bismuth oxide nanoparticles. This includes energy-dispersive X ray spectroscopy, diffuse reflection spectroscopy, Fourier transform infrared spectrum, as well as ultraviolet-visible spectrophotometer. The size, morphology and UV protection properties of nanoparticles made of bismuth oxide were determined.
Bismuth oxide nanoparticles are synthesized using green process of synthesis. The synthesis was carried out with Mentha pulegium powder. This method of green synthesis has attracted much attention in recent times. There is an enormous potential for this method in the cosmetic and pharmaceutical industries.
Bismuth oxide nanoparticles had absorption peak in the 200-400 nm range. It was due to formation of a bismuth oxide polymorph. Bismuth oxide nanoparticles additionally showed UV blocking ability. Nanoparticles also had antibacterial properties.
Bismuth oxide powder is synthesized using a straightforward combustion technique. The powder was then dried in vacuum. The surface's morphology could be assessed via FESEM. The atomic weight of bismuth oxide was 2.7 (eV).
The calcination time for high purity superfine bismuth oxides was 612 hours. The calcining temperature ranged from 450-600 degC. The powders have particle sizes in the range of 0.1-0.5 mm.
The band gap energy of bismuth oxide powder has been determined by plotting the UV-DRS spectrum. Energy band gap of bismuth Oxide powder is 2.7 (eV).
Bismuth oxide nanoparticles demonstrated antibacterial activities against Gram-negative and Gram-positive bacteria. The UV protective properties were also assessed using diffuse reflection. The optimal time for the synthesis of nanoparticles was also assessed using UV-Visible spectrophotometers and Fourier Infrared Transform Spectroscopy.
Bismuth oxide nanoparticles possessed good dispersibility. The UV-protection properties of the bismuth oxide nanoparticles are due to the dynamic light scattering characteristic that the particles possess. The bismuth oxide powder features high purity and good dispersibility and is therefore suitable for the electronic sector.
Synthesis Bismuth Oxide Powder
Different methods have been utilized to synthesize bismuth oxide powder. The hydrothermal method is just one of the methods. It can produce powders with excellent crystalline quality.
The method of spray pyrolysis is yet another method of the production of bismuth oxide. It has been used for a variety of purposes, such as gas sensing. Electrospinning is also been used for the production of nanofibers. Sol-gel is yet another technique which produces powders with an extremely narrow pore distribution.
The mineral distributions of bismuth were observed using the scanning electron microscope. A crystalline structure was also confirmed using X-ray difraction. Numerous spectroscopic techniques including dynamic light scattering, F-IR, XRD and UV-Visible spectroscopy were employed to study the samples.
The UV-visible absorption spectrum was determined to test the UV protection properties of the nanoparticles. The wavelength of UV absorption ranges from 250 to 700 nm. The absorption peak of bismuth oxide is around 300 nm.
The antibacterial property of nanoparticles was also examined using the method of disk diffusion. The antibacterial capability of bismuth oxide was assessed against the salmonella ATCC 1231. They were then stained using different levels of samples. The radius of inhibition was determined by using a ruler.
This green process for synthesising nanoparticles has attracted a lot of attention over the last years. It has been employed for various applications in pharmaceutical and food industries.
Nanoparticles of Bismuth oxide can also be utilized to block UV radiation. They are highly pure and can be used for antibacterial activities. The photocatalyst made of bismuth oxide has an extensive spectrum of absorption that is capable of removing organic molecules. It is also helpful when it comes to water treatment.
The applications for Bismuth Oxide Powder
One of the numerous uses for bismuth powder are metal surface treatment products, plastics and coatings. The powder plays a vital role in chemical vapour dispersion, thermal-evaporation or electron beam-evaporation.
Bismuth oxide nanoparticles were investigated as radiosensitizers. Radiosensitizers are able to enhance the effects radiation on the viability of cells. This can cause damage to DNA of cells.
Nanoparticles have a high surface area which can be utilized for the purpose of target imaging. They also display a high radiopacity. Bismuth oxide nanoparticles are included in a variety items, including lasers, surgical instruments, as well as magnetic field sensor. They are also used in the monitoring of bismuth accumulation.
Bismuth oxide nanowires of high crystalline quality have been made by induced stress in low temperature. These materials are used as radiosensitizers Megavolt and Kilovolt radiotherapy.
Nanostructured bismuth materials have gained plenty of interest due to the quantum behavior of the material. They are also useful in thermoelectric coolers and optical devices.
Bismuth oxide has also been proven to be beneficial on biological uses. Bismuth based medical formulations are frequently used for stomach disorders. Bismuth is also utilized in astringents, bacteriostatic agents and refrigerants. It has also been utilized in nuclear industry as a refrigerant. It also acts as a alternative to led in equipment for electrical use.
Bismuth is used in a myriad of ways from the 19th century onward. However, the use of bismuth slowed down in late in the century of the 20th. It was due to the reversibility of bismuth encephalopathy. There are however several treatments that require the latest technologies.
