This product is made of a nanocomposite consists of copper alloy reinforced with aluminum oxide nanoparticles with the average size of 10 nm, which are uniformly distributed in the copper matrix. Aluminum oxide is produced through a process in which oxygen reacts with aluminum in the copper lattice in the solid state. This method, in comparison with other techniques, has the best particle size and distribution. Aluminum oxide is very hard, thermally stable and insoluble in copper. These particles not only increase the copper alloy strength but also have no significant effect on reducing the thermal and electrical conductivity of copper. The electrode tips are produced in different male or female types by cold forming process or in some cases by the machining process.
Addition of aluminum oxide nanoparticles increases the hardness and tensile properties of the copper alloy. These features are created through the pinning of dislocations by aluminum oxide nanoparticles, which consequently postpone the crystallization process.

The latest evolution in the filtration industry is the use of nanotechnology in this field. With this technique, the surface of large cellulosic or synthetic fibers (usually 10 to 30 micrometers in diameter) is covered with a layer of ultra-fine nanofibers (typically 50 to 400 nanometers in diameter). In this method, before the pleating process, the filter paper is covered with a layer of polymeric nanofibers with diameter of 50 to 300 nanometer by using an electric field. Nanofibers form because of the existence of a large potential difference.
The Covid-19 IgG/IgM rapid test cassette is a rapid and qualitative assay for the detection of antibodies to Coronavirus. This kit has two aluminum packs including a Test cassette and a silica gel, lancet, dropper and an alcoholic pad. Rapid test kit Covid-19 is used for 15 minutes in a room temperature and the result will appear will appear within 3 to 15 minutes, also the result may not be reliable after 20 minutes.
Optical mirrors are designed to reflect light in a variety of applications such as light steering, interferometry, imaging, and general applications. These mirrors are widely used in the various industries, especially in the automotive industry. In conventional mirrors, the unwanted light scattering has negative effects on the efficiency and product performance, as far as it reduces the visibility. Nanocoating technology improves the performance of these mirrors, in a way that is minimizing the light scattering.
For the purpose of preventing wear, reducing friction, and high-temperature load-bearing, Lubricants used in a variety of fields such as transport equipment, turbines, compressors and oil equipment. Currently, lubricants are mainly used in diesel, gasoline and natural gas engines. In recent years, the use of additives containing sulfur and phosphorus in production of motor oils has been associated with environmental problems. Recently, by considering the use of nanotechnology in different industries, nano additives for engine oils have been developed. Nanomaterials as oil additives can reduce torque, engine friction coefficient and wear. which result in decreasing fuel consumption, improving performance, and extending the engine life. Moreover, nanomaterials by entering the surface cavities can repair or fill the pores.
