New nanotechnology processing can produce nanomaterials on an industrial scale

Illinois Institute of Technology recently discovered a new technique reduce the time of nanotechnology processing and increase the amount of product.

According to Nanowerk News, the larger amount of product can be manufactured on an industrial scale, meaning the new technique makes nanotechnology economically viable for numerous applications, such as pollution control, reduction in waste heat from vehicles and electronics and toxic waste removal from water.

Philip Nash, one of the researchers on the project, said to Nanowerk: “This novel approach is capable of producing nanostructured material on an industrial scale and on an economically viable time-scale thus overcoming two major hurdles in nanotechnology; inability to scale up to industrial production quantities and economically unacceptable synthesis times.”

Nash worked with Yang Zhou and Tian Liu of Armour College of Engineering’s Department of Mechanical, Materials and Aerospace Engineering, and Naiqin Zhao and Shengli Zhu from Tianjin University, China on the paper. Titled ‘The Large Scale Synthesis of Aligned Plate Nanostructures, they wrote: “We propose a novel technique for the large-scale synthesis of aligned-plate nanostructures that are self-assembled and self-supporting.

“The synthesis technique involves developing nanoscale two-phase microstructures through discontinuous precipitation followed by selective etching to remove one of the phases.

“The method may be applied to any alloy system in which the discontinuous precipitation transformation goes to completion. The resulting structure may have many applications in catalysis, filtering and thermal management depending on the phase selection and added functionality through chemical reaction with the retained phase.

“The production of the nanostructure requires heat treatments on the order of minutes and can be performed on a large scale making this synthesis technique of great economic potential.”
