#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
ultrafine grained and nanostructured materials. The process was designed in a way that it enabled the researchers to produce nanocomposite and nanostructured metal at the same time.
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.

Researchers at the University of Georgia have developed an inexpensive way to manufacture extraordinarily thin polymer strings commonly known as nanofibers.
These polymers can be made from natural materials like proteins or from human-made substances to make plastic,
rubber or fiber, including biodegradable materials. The new method, dubbed"magnetospinning"by the researchers, provides a very simple,
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,

Researchers in China have created a new 3-dimensional polypyrrole aerogel-based electromagnetic absorber material that can serve as an inexpensive alternative to costly graphene aerogels Abstract:
Conventional materials used today to shield from incoming electromagnetic waves tend to be sheets of metal or composites,
and Technology to tap into organic chemistry and conducting polymers to fabricate a three-dimensional (3-D) polypyrrole (PPY) aerogel-based electromagnetic absorber.
because it enables them to"regulate the density and dielectric property of conducting polymers through the formation of pores during the oxidation polymerization of the pyrrole monomer,"
"We're also able to pour the Fecl3 solution directly into the pyrrole solution--not drop by drop--to force the pyrrole to polymerize into a 3-D aerogel rather than PPY particles."
"In short, the team's 3-D PPY aerogel is designed to exhibit"desirable properties such as a porous structure and low density,"Wu noted.
the team's new aerogel has the lowest adjunction and widest effective bandwidth--with a reflection loss below-10 decibels.
In terms of applications, based on the combination of low adjunction and a"wide"effective bandwidth, the researchers expect to see their 3-D PPY aerogel used in surface coatings for aircraft.
"If our 3-D PPY aerogel could build a conductivity network in this type of coating,
"Our goal is to grow solid-state polymerized PEDOT particles in the holes of the 3-D PPY aerogel formed by PPY chains,"Wu added d
A number of crystals produce this effect, called frequency doubling or harmonic generation, to various degrees.
The strongest frequency doubler previously known is the synthetic crystal beta barium borate, but the nano-spirals produce four times more blue light per unit volume.

which resist chemical degradation. They can also be made on plastic, paper and a number of other substrates."

#Crystal structure and magnetism--new insight into the fundamentals of solid state physics: HZB team decodes relationship between magnetic interactions and the distortions in crystal structure within a geometrically'frustrated'spinel system Abstract:
A team at HZB has carried out the first detailed study of how magnetic and geometric ordering mutually influence one another in crystalline samples of spinel.
To achieve this, the group synthesized a series of mixed crystals with the chemical formula Ni1-xcuxcr2o4 in
They discovered through neutron scattering experiments at BER II not only how the crystal structure changes, but also uncovered new magnetic phases.
and as heat-resistant and magnetic materials. The embedded metal ions in the Ni1-xcuxcr2o4 spinel system cause a distortion of the crystal structure.
In addition, they also display magnetic moments due to the geometrical structure that cannot be oriented as they otherwise would be.
The exciting thing about this series of mixed crystals is that nickel or copper atoms sit at
what are referred to as tetragonal sites of the crystal structure. Due to their different configurations of electrons, these tetrahedra become elongated along the crystallographic c-axis for nickel,
The distortion of the crystal structure can thus be controlled, which in turn has an effect on the magnetic ordering.
Manfred Reehuis and Michael Tovar were successful in determining the structural and magnetic properties for each of the mixed crystal specimens over quite a wide temperature range,
This shows that the crystal structure is cubic (three right angles three equal edges) at high temperatures, since the kinetic energy of the atoms still suppresses the Jahn-Teller effect
and thereby prove there is a relationship between the conditions for magnetic ordering and the crystal structures.
especially when they are in a geometrical system like a crystal, rather than in isolation",says Michael Tovar v

The researchers worked with both zinc oxide and silicon nanowires, and found that -when bent-the nanowires would return more than 80 percent of the way to their original shape instantaneously,
For instance, zinc oxide nanowires exhibited anelastic behavior that is up to four orders of magnitude larger than the largest anelasticity observed in bulk materials,
which are coated with a charged polymer layer that helps them adhere to the target microbes,
and Staphylococcus epidermis, a bacterium that can cause harmful biofilms on plastics-like catheters-in the human body.
Caltech researchers adopted a novel technique, ultrafast electron crystallography (UEC), to visualize directly in four dimensions the changing atomic configurations of the materials undergoing the phase changes.
"To study this, the researchers used their technique, ultrafast electron crystallography. The technique, a new development--different from Zewail's Nobel prize-winning work in femtochemistry, the visual study of chemical processes occurring at femtosecond scales--allowed researchers to observe directly the transitioning atomic configuration of a prototypical phase-change

This objective was achieved by creating a homogenous coating made of a nanocomposite of zinc oxide/nitrogen silver (N-Ag/Zno) on the fabrics.
