NSF establishes Triangle (NC) Center for Soft Matter Research
(Nanowerk News) Recognizing that some of the leading scientists and engineers involved in soft matter research are located in the Research Triangle Park area, the National Science Foundation has provided a six-year, $13.6 million grant to establish a multi-university center to investigate aspects of this promising area of scientific endeavor.
Researchers from Duke University, North Carolina State University, the University of North Carolina-Chapel Hill and North Carolina Central University will focus their collective expertise on facets of soft matter research, a branch of materials science with almost limitless practical applications, from organic solar cells to tissue implants to new classes of drugs.
In general terms, soft matter describes such states of matter as foams, gels, polymers or emulsions. They are typically created by combining smaller particles – such as DNA, proteins, nanoparticles – to form larger structures with novel properties. The researchers involved in this project will not only investigate how and why these particles assemble in certain ways, but also how this assembly can be manipulated to achieve soft matter with defined characteristics.
The new initiative will be known as the Triangle Materials Research Science and Engineering Center (MRSEC). The center joins a network of university centers across the country, each of which has a specific focus on a cutting edge area of materials science.
Gabriel Lopez"We believe that the Triangle MRSEC will become an important national and international center for innovation in the field -- including the theoretical generation of new insights, creation of new functional materials, development of new applications, commercialization and education," said principal investigator Gabriel López, professor of biomedical engineering and mechanical engineering, and materials science at Duke.
"The fundamental understanding, design and application of these new types of materials will have implications across diverse fields of science, technology and medicine," López said. "We plan to turn these findings into practical realities through relationships with existing companies as well as start-up companies likely to arise from the research."
N.C. State's Carol Hall, a professor of chemical and biomolecular engineering, serves as co-principal investigator.
"This center is the remarkable result of a convergence of ideas from some of the world's leading soft matter experts at universities right here in the Triangle," Hall said. "Working together, this diverse group will develop new materials that helps solve some of humanity's most challenging problems while jump-starting the careers of the next generation of soft matter researchers and entrepreneurs."
The Triangle MRSEC will follow two main research thrusts, each led by a senior faculty member at Duke and N.C. State. The Triangle researchers working on these thrusts will collaborate with scientists from Europe and Asia, as well as the National Institute of Standards and Technology and several other institutions across the country.
The first thrust, led by N.C. State's Orlin Velev, a professor of chemical and biomolecular engineering, will explore in detail how small particles – known as colloids – combine in liquid, and furthermore, what kinds of strategies can be employed to control how these assembling particles form new materials with unique properties and functions.
The second thrust, led by Duke biomedical engineering professor Ashutosh Chilkoti aims to create a "syntax" with building blocks made up of polymers, DNA and proteins that can assemble into nano-scale structures. Just as letters make up words, and words make up sentences, these scientists plan to create a library of useful building blocks – letters and words -- from which larger structures – sentences -- can be built. UNC chemistry professor Michael Rubinstein will be developing the theory of polymer self-assembly.
An integral part of the new MRSEC is the development of young faculty members, who can apply for "seed" funding for their research ideas. Two such projects have already been funded: one involving N.C. Central faculty and students developing ways of changing the structure and properties of polymers and gels using heat, electricity and mechanical force; and another involving faculty from Duke and N.C. State looking into the potential of novel soft materials as that can be used as electrically driven mechanical actuators.
In addition to the broad range of scientific pursuits, the Triangle MRSEC will provide educational opportunities for undergraduates, graduate students and post-doctoral fellows at each of the institutions to foster their interest in soft matter research. An outreach program is also planned to help interest pre-college age students in pursuing careers in the sciences.
