Iranian Technologists Indigenize Nanolayer for Application in Medicine, Nuclear Industry
“This product is classified as a nanolayer or nanofilm and consists of a thin layer of tellurium oxide deposited on a substrate. This structure is highly sensitive to gamma rays and can be used in various industries, including medicine and even the nuclear field,” Robab Talebzadeh told ANA.
My research in the form of a doctoral thesis focused on examining the sensitivity of this nanolayer to gamma rays; because in the sterilization process of materials, accurate measurement of the radiation dose is of great importance,” she added.
Talebzadeh noted that a laboratory sample of the product has been designed, and if the necessary equipment is provided, it can be commercialized.
The Sixteenth International Nano Technology Exhibition and the First Exhibition of Advanced Technologies of Iran was inaugurated at the Tehran International Fairground.
Running from November 2 to 5, the Nano Exhibition featured over 150 innovative companies showcasing advancements in nanotechnology. Meanwhile, the Exhibition of Advanced Technologies hosted 80 knowledge-based and technological products, attracting visitors, particularly students, researchers, and investors.
In a relevant development in September, an Iranian knowledge-based company had succeeded in designing and manufacturing a device for depositing ultra-hard coatings by using the physical vapor deposition (PVD) method.
By creating nanostructured coatings on industrial parts, the technology significantly increases the lifespan and performance efficiency of tools and parts in the oil and gas, power plant, aerospace, medical, and automotive industries.
One of these methods is the creation of nanostructured coatings using the physical vapor deposition (PVD) method on the surface of parts, the development of which was put on the agenda of one of the Iranian knowledge-based companies and they designed and manufactured a device for depositing ultra-hard coatings using PVD.
In this method, the part is placed inside a vacuum chamber, and after creating a vacuum to very low pressures, certain metals such as titanium, chromium, zirconium, etc. are evaporated and ionized. In fact, a metal-active plasma is created in the chamber and, as different gases enter the chamber, the combination of gas and metal causes the formation of ceramic nanoparticles that deposit the main composition of the coating on the surface of the parts.
The result of this process is a dense and ultra-hard coating with a thickness of several nanometers to several micrometers, which, depending on the conditions of use of the coating, its combined compositions are applied to the part. The most important applications of these coatings include various tools, molds and industrial parts like the parts needed in the oil and gas, power plant, aerospace, medical and automotive industries.
Among the technical and specialized features of this product, which is also considered a competitive aspect, is the coating application software and innovations used in the device modules, which enable the implementation of different coatings in the form of a single device. This device also enjoys the capability to simultaneously implement coatings of nanolayers and nanocomposites. It can perform various coatings both automatically and manually, which makes it unrivaled in the domestic market.
