The size, morphology, as well as UV-protective properties of bismuth oxide nanoparticles have been studied.
Bismuth oxide nanoparticles were created using green chemical synthesis. The synthesis was conducted using Mentha pulegium powder. This green synthesis method has gained a lot attention in recent times. There is an enormous potential for this technique in the cosmetic and pharmaceutical industries.
Bismuth oxide nanoparticles displayed absorption peaks that ranged from 200 to 400 nm range. This is due to formation of a bismuth oxide-like polymorph. Bismuth oxide nanoparticles also showed UV blocking abilities. The nanoparticles were also antibacterial.
Bismuth oxide powder is synthesized using a simple combustion method. The powder was dried under vacuum. The surface's morphology was analyzed via FESEM. The atomic weight of bismuth oxide powder was 2.7 eV.
The calcination duration of high purity superfine bismuth oxides were 612 hours. 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 energy of the band gap in bismuth oxide was calculated by plotting UV-DRS spectrum. This energy band gap for bismuth oxide powder is 2.7 (eV).
Bismuth oxide nanoparticles showed antibacterial activities against Gram-negative and Gram-positive bacteria. The UV protective properties were examined using diffuse reflection spectroscopy. The optimal time to synthesize nanoparticles also was determined by UV-Visible spectrophotometer as well as Fourier Infrared Transform Spectroscopy.
Bismuth oxide nanoparticles were able to exhibit good dispersibility. The UV protective properties of bismuth oxide nanoparticles are due to the dynamic light scattering capability that the particles possess. Bismuth oxide powder boasts great purity and good dispersibility making it ideal for the electronic industry.
Synthesis Bismuth Oxide Powder
There are a variety of methods used to make bismuth oxide powder. Hydrothermal technique is one of them. It produces powders of exceptional crystalline properties.
The method of spray pyrolysis is another technique used for making bismuth oxide powder. It is used in various applications , like a gas sensing application. The electrospinning method has also been used for the production of nanofibers. Sol-gel is a different method for producing powders that have the smallest pore size.
The mineral distributions of bismuth were observed with the scanner electron microscope. The crystal structure was confirmed by Xray diffraction. Several spectroscopic techniques such as dynamic light scattering, F-IR, XRD and UV-Visible spectroscopy were used to evaluate the samples.
The spectrum of UV-visible absorption was determined to test the UV protective properties of nanoparticles. The wavelength of absorption for UV ranges between 250 and 700 nm. The absorption peak for bismuth oxide occurs at the wavelength of 290 nm.
The antibacterial property of nanoparticles also was studied using an approach to diffusion of disks. Bismuth's antibacterial properties oxide was evaluated in comparison to salmonella ATCC 1231. A disc was stained with different levels of samples. The diameter of the zone inhibition was measured using an instrument called a ruler.
A green-colored synthesis process of nanoparticles have received a lot of attention in recent times. It is used in numerous applications in the food industry and pharmaceutical industry.
Nanoparticles made of Bismuth oxide are used for UV blocking. They have high purity and can be used for antibacterial properties. Bismuth oxide is a photocatalyst with an absorption spectrum that is broad and has the capacity of eliminating organic molecules. It is also useful in the treatment of water.
Applications of Bismuth Oxide Powder
Some of the many uses for bismuth oxide powder , there are surface treatment products, plastics and coatings. The powder is also a important role in chemical vapor removal, thermal evaporation as well as electron beam evaporation.
Bismuth oxide nanoparticles can be examined as radiosensitizers. The radiosensitizers improve the effects radiation on cell viability. This causes damage to DNA within cells.
Nanoparticles possess a large surface area, and they can be used to target image. They also have a high radiopacity. Bismuth oxide nanoparticles can be utilized in a variety items, including health devices, optical filter as well as magnetic field sensor. They are also used for monitoring traceable bismuth accumulation.
Bismuth oxide nanowires with excellent crystal quality were produced through the induced stress process by low-temperature induced stress. These materials have been used as radiosensitizers during Megavolt or Kilovolt radiotherapy.
Nanostructured bismuth has attracted plenty of interest due to the quantum properties of this material. They can also be used in power generators, thermoelectric coolers, as well as optical devices.
Bismuth oxide has also been shown to be beneficial on biological uses. Bismuth used in medical formulations is still being used to treat stomach issues. Bismuth can also be used for astringents in addition to bacteriostatic compounds and refrigerants. It is also employed in nuclear industry as a refrigerant. It also serves as a alternative to lead in electrical equipment.
Bismuth was used in a myriad of ways since the 19th century. However, use of bismuth slowed down in early 20th century. This was due in part to reversible bismuth encephalopathy. However, there are still numerous treatments that require new technology.
