Potential applications include safety gear for U.S. soldiers and filtration systems for buildings and vehicles.
Hinestroza, assistant professor of fiber science in the College of Human Ecology, is a member of two teams that secured more than $2.2 million from the U.S. Department of Defense; about $875,000 will go directly to Hinestoza's work. Both grants are multi-university collaborative efforts funded through the U.S. Defense Threat Reduction Agency.
"These nanostructures could be used in creating advanced air filtration and personal protection systems against airborne chemical threats and can find many applications in buildings, airplanes as well as personal respirators," Hinestroza said.
The first project, in collaboration with North Carolina State University, is aimed at understanding how very small electrical charges present in fibers and nanofibers can help in capturing nanoparticles, bacteria and viruses.
"Understanding how these charges are injected into the fibers and how they are dissipated under different environmental conditions can open an avenue to significant improvements in air filtration technology," Hinestroza said.
The position and distribution of the electrical charges on the nanofibers will be fed into computerized fluid dynamics algorithms developed by Andrey Kutznetsov of NC State to predict the trajectory of the nanoparticles challenging the filter. Hinestroza and NC State's Warren Jasper pioneered work in this area a couple of years ago.
capture them for further decontamination. The synthesis of these molecules was pioneered by Omar Yaghi of UCLA.
This project will also look into the potential toxicity of these nanofiber-nanoparticle systems to humans in collaboration with Andre Nel from UCLA Medical School.
Hinestroza's research group specializes in understanding and manipulating nanoscale phenomena in fiber and polymer science.

Cells need to repair damaged DNA in our genes to prevent the development of cancer and other diseases. Our cells therefore activate and send “repair-proteins”...
The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.
The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".
Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
