Electromagnetic levitation whips nanomaterials into shape


 E-Mail
In order for metal nanomaterials to deliver on their promise to energy and electronics, they need to shape up literally.
To deliver reliable mechanical and electric properties, nanomaterials must have consistent, predictable shapes and surfaces, as well as scalable production techniques. UC Riverside engineers are solving this problem by vaporizing metals within a magnetic field to direct the reassembly of metal atoms into predictable shapes. The research is published in The
Journal of Physical Chemistry Letters.
Nanomaterials, which are made of particles measuring 1-100 nanometers, are typically created within a liquid matrix, which is expensive for bulk production applications, and in many cases cannot make pure metals, such as aluminum or magnesium. More economical production techniquess typically involve vapor phase approaches to create a cloud of particles condensing from the vapor. These suffer from a lack of control. ....
