Abstract of Bismuth Oxide Powder
Various spectroscopic techniques were used to analyze bismuth oxide particles. This includes energy-dispersive X ray spectroscopy, diffuse reflection spectroscopy, Fourier transform infrared spectroscopy, along with ultraviolet-visible UV spectrophotometer. The size, morphology, as well as UV-protective properties from bismuth oxide nanoparticles were studied.
Bismuth oxide nanoparticles are synthesized through green synthesis. The synthesis was carried out with Mentha pulegium extract. This method of green synthesis has drawn a lot of attention recent times. It has a huge opportunity for this method in the cosmetic and pharmaceutical industries.
Bismuth oxide nanoparticles had absorption peaks that ranged from 200 to 400 nm range. It was due to formation of the bismuth oxide polymorph. Bismuth oxide nanoparticles also showed UV blocking capabilities. The nanoparticles showed antibacterial activity.
Bismuth oxide powder was prepared with a simple combustion process. The powder was then dried in vacuum. The surface's morphology could be assessed with FE-SEM. The atomic number for bismuth oxide was 2.7 eV.
The calcination period of superfine bismuth oxides, high purity, was 612 hours. The temperature of calcination was between 450 and 600 degrees Celsius. The powders have particle sizes that range from 0.1-0.5 millimeters.
The band gap energy of bismuth oxide powder was determined through plotting the UV-DRS spectrum. Energy band gap for 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 investigated by diffuse reflection spectroscopy. The optimal time of synthesis for nanoparticles also was determined by UV-Visible spectrophotometer as well as Fourier shift infrared spectrum.
Bismuth oxide nanoparticles were able to exhibit good dispersibility. The UV-protection properties of the bismuth oxide nanoparticles are due to the ability to scatter light dynamically for the tiny particles. The bismuth oxide powder has great purity and good dispersibility that is ideal for the electronic sector.
Synthesis of Bismuth Oxide Powder
There are a variety of methods used to synthesize bismuth oxide powder. Hydrothermal is one of them. It can create powders with crystallized quality that is high.
The method of spray pyrolysis is another method for synthesizing bismuth oxide powder. It has been employed in many applications like gas sensing. The electrospinning method has also been utilized to make the production of nanofibers. Sol-gel is yet another method that produces powders with a pores that are narrow.
The elements of the bismuth crystal were observed using the scan electron microscope. A crystallized structure was confirmed with X-ray diffraction. Several spectroscopic techniques such as dynamic light scattering, FTIR, XRD and UV-Visible spectroscopy were used to evaluate the samples.
The spectrum of UV-visible absorption was studied in order to evaluate the UV protection properties of the nanoparticles. The wavelength of UV absorption varies between 250 and 700 nm. The absorption peak of bismuth oxide is around 300 nm.
The antibacterial property of nanoparticles was also examined using the disk diffusion method. The antibacterial power of bismuth oxide was tested on salmonella ATCC 1231. Disks were stained with different levels of samples. The area of inhibition was measured using the ruler.
A green-colored synthesis process of nanoparticles have gained a lot of interest in recent time. It is being used for different applications in the pharmaceutical and food industries.
Nanoparticles made of Bismuth oxide are employed for UV blocking. They are highly pure and are beneficial for antibacterial action. The bismuth photocatalyst features an absorption spectrum that is broad and has the capacity of eliminating organic molecules. It is also helpful in the treatment of water.
Uses of Bismuth Oxide Powder
A few of the applications for bismuth oxide powder , there are surface treatment products, plastics, and coating products. The powder also plays a crucial role in chemical vapor of deposition as well as thermal evaporation along with electron beam and solar evaporation.
Bismuth oxide nanoparticles are being studied as radiosensitizers. Radiosensitizers enhance the effects radiation on cell viability. This causes damage to DNA within cells.
Nanoparticles possess a large surface area, and they can be used for target imaging. The particles also exhibit high radiopacity. Bismuth oxide nanoparticles can be added to a variety devices, such as optic filters, medical equipment, and magnetic field sensors. They are also used in the monitoring of the accumulation of bismuth.
Bismuth oxide nanowires that have excellent crystal quality were created through the induction of stress by low-temperature induced stress. These materials are used as radiosensitizers Megavolt or Kilovolt radiotherapy.
Nanostructured bismuth materials have attracted plenty of attention due to the quantum properties of the material. They are also used in thermoelectric coolers and optical devices.
Bismuth oxide has also been proven to be beneficial as a biological agent. Bismuth derivatives for medical use are still being used for stomach disorders. Bismuth is also utilized in astringents, bacteriostatics and refrigerants. Bismuth is also utilized in nuclear industries as refrigerant. It can also be used as a alternative to led in equipment for electrical use.
Bismuth has been used in many different ways from the 19th century onward. However, the use of bismuth became less frequent in around the turn of the twentieth century. This was due to reversible bismuth encephalopathy. But, there are a number of established treatments that require new technology.
