The NDSU researchers have developed a family of resins from renewable raw materials, creating resins that eliminate hazardous components such as formaldehyde and bisphenol-A. The resins are based on sucrose and vegetable oils, and can be varied to perform in many applications and industries, according to Dean Webster, professor in the NDSU Department of Coatings and Polymeric Materials. Webster’s research group includes NDSU graduate students Xiao Pan and T. J. Nelson, undergraduate student Adlina Paramarta and Partha Sengupta, former postdoctoral researcher at NDSU.
The resins developed by the NDSU research group can be made from from sugarbeets, plus oils from soybeans, flax and sunflowers. When cured, the patent-pending resins show:- Significantly improved properties over current biobased materials and processes
The new resins developed at NDSU could further reduce reliance on petrochemical-based materials, one of the main components in many coatings formulations. Dr. Webster’s research group found that the epoxidized sucrose ester resins they developed result in materials that are two- to-four times as functional as vegetable oil-based resins.
One novel ultraviolet light curable coating developed by Webster’s group cures approximately 10 times faster than existing UV-curable biobased coatings. Another in the family of biobased resins developed at NDSU exhibits properties that make it ideally suited for bio-composite materials, baking enamels and structural adhesives. Another resin demonstrates more hardness and resistance to solvents than petrochemical-based coatings.
“Interest in the use of renewable feedstocks in the synthesis of polymers is rapidly increasing, driven by consumer demand for ‘green’ products as well as the tightening of the supply of petrochemicals,” said Webster. “However, consumers are requiring that the biobased materials have physical properties that match or exceed current high performance materials.”
Laboratory research at NDSU has shown that the green technology resins developed at NDSU are far superior to existing biobased materials and comparable to petrochemical-based materials. The newly-developed resins could be used in a variety of settings including construction, architectural, biomedical, marine and electronics industries. The technology may have wide-ranging applications in areas where thermally cured materials are used, such as in protective coatings, structural adhesives, and composites. The resins are synthesized using raw materials, reagents and processes common to industry.
“They have the potential to provide a revolutionary impact in some applications replacing widely-used petrochemical-based epoxy compounds,” said Webster.
Funding for the biobased coatings research was provided by the USDA Cooperative State Research, Education, and Extension Service under grant number 2007-38202-18597. The United Soybean Board is sponsoring current biobased coatings research at NDSU. The base sucrose ester resins used in this research were provided by P&G Chemicals.
Webster’s research is among a broad-based research portfolio in renewable technologies at NDSU, with research funded by USDA, the National Science Foundation, U.S. Department of Energy and entities in North Dakota, including the North Dakota Renewable Energy Council and North Dakota Soybean Council.
Webster has been involved in polymer synthesis and structure-property relationships of coating binder systems for more than 20 years. He is receiving the prestigious Roy W. Tess Award in Coatings from the American Chemical Society on August 29, 2011, during the group’s annual meeting in Denver, Colo.
Dr. Webster has authored more than 75 peer-reviewed papers and publications and is credited with 11 patents (an additional 18 pending) on coatings related topics. He has won Roon Foundation Awards for the best paper in the 2003, 2004 and 2006 International Coatings Exposition (ICE) of the American Coatings Association.
Dr. Webster’s career in the coatings industry includes research and development in the Consumer Division of Sherwin-Williams in Chicago, Ill., and at Eastman Chemical Company. He received his Ph.D. in materials engineering science and his B.S. degree in chemistry at Virginia Polytechnic Institute and State University.More information:

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
