A world analysis crew led by NUST MISIS has developed a brand new iron-cobalt-nickel nanocomposite with tunable magnetic properties. The nanocomposite may very well be used to guard cash and securities from counterfeiting.
Presently, analysis on magnetic nanomaterials with managed magnetic traits is without doubt one of the most promising fields. Attributable to their small dimension, in addition to their wonderful magnetic and electrical properties these supplies have a broad vary of potential purposes from cellular gadgets to area applied sciences.
The brand new iron-cobalt-nickel nanocomposite was obtained by chemical precipitation, adopted by a discount course of.
“This methodology is easy and, most significantly, it permits the properties of the product to be managed at every stage of its manufacturing, and chemically pure nanopowders to be produced with a given composition, form, and dispersion,” famous Yuri Konyukhov, Deputy Head of the Division of Practical Nanosystems and Excessive-Temperature Supplies at NUST MISIS.
Konyukhov additionally burdened that the brand new composite was noticed to own excessive worth of coercivity, which makes the expertise relevant e.g. to magnetic rubbers and completely different magnetically coupled gadgets. One other potential software is defending cash and securities from counterfeiting.
“The efforts of the scientific neighborhood have been not too long ago targeted on defending people and digital gadgets from electromagnetic radiation. The event of skinny, versatile and comparatively clear metal-polymer composites for EMI shielding is a promising analysis route. The usage of the brand new nanocomposite with managed magnetic properties because the magnetic filler may result in a breakthrough in EMI safety,” added Yuri Konyukhov.
