Helping Corn-Based Plastics Take More Heat

03.09.2010
Your favorite catsup or fruit juice might be "hot-filled" at the food-processing plant—that is, poured into its waiting container while the catsup or juice is still hot from pasteurization. Current containers made from corn-based plastics literally can't take the heat of hot-filling, according to U.S. Department of Agriculture (USDA) chemist William J. Orts.

But Orts and a team of collaborators from Lapol, LLC, of Santa Barbara, Calif., hope to change that by making corn-derived plastics more heat-tolerant. Orts and Lapol co-investigators Allison Flynn and Lennard Torres are doing the work at the Agricultural Research Service (ARS) Western Regional Research Center in Albany, Calif., where Orts leads the Bioproduct Chemistry and Engineering Research Unit. ARS is USDA's principal intramural scientific research agency.

By boosting the bioplastics' heat tolerance, the collaboration—under way since 2007—may broaden the range of applications for which corn-derived plastics could be used as an alternative to petroleum-based plastics.

Corn-based plastics are made by fermenting corn sugar to produce lactic acid. The lactic acid is used to form polylactic acid, or PLA, a bioplastic. The Albany team is developing a product known as a heat-deflection temperature modifier that would be blended with PLA to make it more heat-tolerant.

The modifier is more than 90 percent corn-based and is fully biodegradable. There currently are no commercially available heat-deflection temperature modifiers for PLA, according to Randall L. Smith, chief operating officer at Lapol. ARS and Lapol are seeking a patent for the invention.

Im Focus: Dresdner scientists print tomorrow’s world

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...

Im Focus: Three Magnetic States for Each Hole

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...
