#Nanotechnology Raises Possibility to Produce Strongest Commercial Pure Aluminum Alloy Iranian researchers from Amirkabir University of Technology in association with Spanish researchers presented a new process to obtain highly strong

automobile manufacturing and all industries related to aluminum and light metals. Novel technologies take step towards the production of lighter but stronger alloys to save energy.
There are three important limitations in the majority of severe plastic deformation (SPD) processes. In these processes
expensive forming devices are required with high load capacity. Low amount of production and limitations in the size of the product are among the other problems of these processes.
The impossibility of production of composite in plastic deformation methods is among the other limitations in these processes.
Due to the abovementioned limitations and the need for the creation of new methods, the researchers proposed a new severe plastic deformation method under the title annular pressure buildup (APB.
In this research, commercial 1050 pure aluminum was used as the base alloy while silicon carbide nanoparticles were used as the strengthening agent.
Results of the research showed that aluminum and its alloys produced through APB process without the creation of any crack
or layers are final consistent products with great quality. According to the researchers, the simultaneous combination of ultrafine grained structure with average particle size of 280 nm
and silicon carbide nanoparticles with aver particle size of 55 nm as strengthening agents results in the production of aluminum-based nanocomposite with a strength of 284 MPA.

study co-author and the Georgia Power Professor of Polymers, Fibers and Textiles in UGA's College of Family and Consumer Sciences."
"Currently, the most common nanofiber manufacturing technique--electrospinning--uses high-voltage electricity and specially designed equipment to produce the polymer strings.
Polymer that has been melted or liquefied in a solution is mixed with biocompatible iron oxide or another magnetic material and placed inside a hypodermic needle.
This needle is positioned then near a magnet that is fixed atop a spinning circular platter. As the magnet passes by the tip of the needle,
a droplet of the polymer fluid stretches out and attaches to the magnet, forming a nanofiber string that winds around the platter as it continues to spin.
"The researchers can use this method to create a variety of nanofibers simply by changing the polymer placed in the syringe.
"We can use almost any kind of polymer with this platform, and we can tailor make the nanofibers for different applications,
