Researchers build structured, multi-part nanocrystals with super light-emitting properties

By Mike Krapfl, Iowa State University News Service

Researchers have developed new types of materials that combines two or three types of nanoparticles into structures that display fundamental new properties such as superfluorescence. “The whole goal of this research is to make new materials with new properties and/or exotic new structures,” said Alex Travesset, an Iowa State University professor of physics and astronomy and an…

Engineered defects in crystalline material boosts electrical performance

By Mike Krapfl, Iowa State University News Service

Materials engineers don’t like to see line defects in functional materials. The structural flaws along a one-dimensional line of atoms generally degrades performance of electrical materials. So, as a research paper published today by the journal Science reports, these linear defects, or dislocations, “are usually avoided at all costs.” But sometimes, a team of researchers from Europe, Iowa State…

Metal whispering: Engineers Finding a Better Way to Recover Precious Metals From Electronic Waste

By Mike Krapfl, Iowa State University News Service

Inspired by nature’s work to build spiky structures in caves, engineers at Iowa State University have developed technology capable of recovering pure and precious metals from the alloys in our old phones and other electrical waste. Using controlled applications of oxygen and relatively low temperatures, the engineers say they can dealloy a metal by slowly…

Engineers use heat-free technology to make metallic replicas of a rose’s surface texture

By Mike Krapfl, Iowa State University News Service

Nature has worked for eons to perfect surface textures that protect, hide and otherwise help all kinds of creatures survive. There’s the shiny, light-scattering texture of blue morpho butterfly wings, the rough, drag-reducing texture of shark skin and the sticky, yet water-repelling texture of rose petals. But how to use those natural textures and properties…

Iowa State University, John Deere Collaboration Advances Research in Hybrid Manufacturing

By Nick Fetty, Iowa State University College of Engineering

Advancements are being made within the field of hybrid manufacturing because of a research collaboration between Iowa State University and John Deere. Matt Frank, a professor in industrial and manufacturing systems engineering, has spent the past year working alongside researchers in John Deere’s Advanced Technology and Engineering group as part of a professional development assignment, also known…

Researchers create nanoscale sensors to better see how high pressure affects materials

Second Science Paper Within a Month for Levitas

By Mike Krapfl, Iowa State University News Service

Researchers have developed new nanoscale technology to image and measure more of the stresses and strains on materials under high pressures. As the researchers reported in the journal Science, that matters because, “Pressure alters the physical, chemical and electronic properties of matter.” Understanding those changes could lead to new materials or new phases of matter for…
