Sportswear giant Reebok has launched a new premium sports bra which integrates Shear Thickening Fluid, a gel-like solution developed by engineers at the University of Delaware that solidifies when in motion to offer enhanced support. View T.Evo article…
Reebok’s PureMove bra weaves in the viscous fluid that is said to have no effect on the look or feel of the fabric. The technologically-enhanced fabric adapts to body shape and movement to offer necessary support depending on the intensity of an activity. The creation of the bra was spearheaded by Danielle Witek, a Reebok designer, who stumbled upon the technology while thumbing through a science journal (something she does for fun). In 2005, chemical engineers at the University of Delaware had invented a new substance called Shear Thickening Fluid, a gel-like solution that takes liquid form when in a still or slow-moving state, and stiffens into a solid when moving at high velocities. It was originally designed to be a modern form of armor technology, since you can incorporate it into a protective garment to defend the wearer from items flying at their body at a high speed–it’s since been used in everything from Kelvar bulletproof vests to NASA spacesuits that protect astronauts from shrapnel.
As Witek read about this amazing fluid, she had her “aha” moment. What if she could incorporate it into a sports bra to provide control and compression when the wearer is in motion, but lighter support when the wearer is still? She reached out to the scientists, beginning the three-year journey that led to Reebok’s PureMove bra…Since this technology is so new, Reebok had to do a lot of testing to make sure the bra would actually do what it advertised. The company set up a breast biomechanics testing center with the help of the University of Delaware, with 54 separate motion sensors tracking and measuring various parts of a tester’s chest area. This is a far more rigorous approach than most testing facilities in the industry that typically only use between two to four sensors. Over the course of a year, the facility gathered the data required for the scientists and Reebok product designers to develop the PureMove bra. View Prosyscom Tech News article…

UD engineers convert commonly discarded material into high-performance adhesive
Different tape has different ingredients in the adhesive and different strengths.
Whether you’re wrapping a gift or bandaging a wound, you rely on an adhesive to get the job done. These sticky substances often are made from petroleum-derived materials, but what if there was a more sustainable way to make them? Now, a team of engineers at the University of Delaware has developed a novel process to make tape out of a major component of trees and plants called lignin—a substance that paper manufacturers typically throw away. What’s more, their invention performs just as well as at least two commercially available products. The researchers recently described their results in ACS Central Science
, and they are working on more ways to upcycle scrap wood and plants into “designer materials” for consumer use.
Lignin is a renewable resource, a substance in trees that helps to make them strong. But you do not have to cut down trees to get it, because there’s plenty lying around. When pulp and paper manufacturers process wood, the lignin is left behind and usually discarded in landfills or burned for heat. Some companies are even willing to deliver a free dump truck full of the stuff because that is cheaper than disposing of it in a landfill. An inexpensive, plentiful and sustainable material, lignin presents a prime opportunity for some scientifically advanced upcycling. Lignin is also a natural polymer, a material made of very large molecules composed of smaller subunits called monomers. Lignin shares some structural and materials property similarities with petroleum-derived polymers, such as polystyrene and polymethyl methacrylate, which are commonly used in adhesives and other consumer products, from packaging materials to cups.
“One of the thoughts that we have always had is: Can we take lignin and make useful products, and in this case, useful polymers out of it?” said Thomas H. Epps, III, the Thomas and Kipp Gutshall Professor of Chemical and Biomolecular Engineering, Professor of Materials Science and Engineering at UD, and the corresponding author of the new paper. In particular, Epps suspected that lignin could be used to make adhesives with similar strength, toughness, and scratch resistance to the petroleum-based versions. Read UDaily Article…

Chemical engineering and materials science professor joins the top 0.5 percent of society members
Thomas H. Epps, III, the Thomas & Kipp Gutshall Professor in the Department of Chemical and Biomolecular Engineering and a Professor in the Department of Materials Science and Engineering at the University of Delaware, has been named a Fellow of the American Physical Society (APS). No more than one-half of one percent of APS members are elected to Fellow Status. Fellows have made significant contributions to the field of physics through research, applications, teaching, or participation in society activities. “It is a great honor to be elected as an APS Fellow,” said Epps. ”Several of my colleagues at UD are APS Fellows, along with many people who I admire in the polymer physics community. It is a great privilege to become a part of this esteemed group in physics. I am extremely grateful to all of my students, postdocs, and collaborators who have contributed to my activities.” Darrin Pochan, chair of the Department of Materials Science and Engineering, and Eric Furst, chair of the Department of Chemical and Biomolecular Engineering, nominated Epps for this honor. “Prof. Epps’ accomplishments in the research and engineering of block-copolymers and his service and leadership in the American Physical Society forum make him exceptionally qualified for this honor,” said Furst. “He is an extraordinary researcher and educator whose work has had a major impact on macromolecular and soft matter science and engineering.”

Arthi Jayaraman recently received a grant to build predictive molecular models of soft materials
UD Engineer Arthi Jayaraman Uncovers Molecular Mysteries
When scientists develop brand new materials, they must precisely determine the ingredients, quantities, and processing methods to use. It’s kind of like creating a recipe. Before spending time and money to test these recipes in a lab, scientists can first use computer simulations to see how the molecules in the ingredients will behave under changing conditions. However, as researchers invent increasingly innovative and complex materials, they need models and simulations that run for longer time scales, and offer resolutions at multiple length scales, than what is available. “New and better models are needed to address current challenges in materials design,” said Arthi Jayaraman, an associate professor in the Department of Chemical and Biomolecular Engineering and Department of Materials Science and Engineering at the University of Delaware. Jayaraman is building better models right here at UD. For this research, she along with collaborators Ryan Hayward of University of Massachusetts Amherst and Paul Butler of National Institutes of Standards and Technology have been awarded a $726,000 grant from the U.S. Department of Energy Office of Basic Energy Sciences.

Stan Sandler of the Department of Chemical and Biomolecular Engineering has served 50 years on the UD faculty.
Chemical engineering’s Stan Sandler reaches 50-year mark as UD faculty member
Stan Sandler usually takes the steps to get to his second-floor office in the University of Delaware’s Colburn Lab. But today he’s taking the elevator because he’s hauling two black bags filled with heavy books — books that will be added to a growing pile destined to be shipped to developing countries including Nigeria and Ethiopia. It’s easy to accumulate a lot of books over the course of an academic career, especially one that spans half a century, and, even with 150 or 200 books already boxed up, the shelves in Sandler’s office are far from empty. While Sandler is proud of those awards — which include membership in the National Academy of Engineering and being named one of the top 30 chemical engineering authors by the American Institute of Chemical Engineers — there are other things for which he would like to be remembered. The first, he says, is the many books he has authored, including two new ones in just the past two years. “One of my texts is now in its fifth edition,” he says. “It not only changed what we do here but also has had an impact on instruction around the world.” He’s also proud of the accomplishments of his students, his efforts to promote the use of computers in chemical engineering instruction, and his initiation of a conference series in thermodynamics that was supposed to be a one-time event but so far has had a 40-year run. The most recent meeting was last year in Porto, Portugal.
Now the Henry Belin du Pont Chair of Chemical Engineering at UD, Sandler has served as department chair and as interim dean of the College of Engineering, but his heart lies with research and teaching, not with administration.

Shear thickening fluid has many applications, including in needlestick-resistant surgical gloves
UD professor featured in American Chemical Society video at SXSW
The hipsters, thought leaders and innovators attending the South by Southwest (SXSW) Festival in Austin, Texas, this week are being introduced to some University of Delaware innovation that’s designed to help people both here on the ground and rocketing off into space. In a video being premiered by the American Chemical Society at SXSW, UD professor Norman Wagner and his interdisciplinary team’s work with shear thickening fluids is showcased — in applications ranging from bullet-proof vests, to needlestick-resistant surgical gloves, concussion-resistant helmets, next-generation prosthetics and even spacesuits. As Wagner explains, shear thickening fluids are “field-responsive” materials meaning that the harder you push on them, the harder they push back. His team’s work to harness this unique capability and provide protection where it currently doesn’t exist — to first responders to doctors to astronauts — is highlighted in one of three short-form documentaries produced by the American Chemical Society. The series illustrates the importance of chemistry in innovation and the cross-collaboration and interdisciplinary nature of today’s scientific endeavors.
In addition to Wagner, who is the Unidel Robert L. Pigford Chaired Professor of Chemical and Biomolecular Engineering at UD, and co-founder of the startup company STF Technologies, the video includes Richard Dombrowski, co-founder of STF Technologies, and research assistant Eric Hobbs, who both received their bachelor’s degrees in chemical engineering from UD, Jehnae Linkins, doctoral student in biomechanics and movement science, and postdoctoral researcher Dr. Maria Katzarova. Eric Wetzel, research scientist and a key partner at the Army Research Laboratory, and John Horne, president of Independence Prosthetics-Orthotics, also are included.
The American Chemical Society, which is participating in the expo hall at SXSW for the first time this year, has more than 157,000 members around the globe. The videos and other information are being presented on its new community engagement platform, the ACS Xchange, which is open to the public. Watch the UD Team’s Video
