Haghshenas Fatmehsari team looking at corn, soybean oil to recycle asphalt

Hamzeh Haghshenas Fatmehsari Hamzeh Haghshenas Fatmehsari and colleagues are studying the efficacy of using corn and soybean oil in the process of recycling asphalt. The rising cost and environmental impact of using crude oil in the process prompted Haghshenas Fatmehsari to explore greener alternatives. He knew that vegetable oils, specifically corn and soybean oil, were great options for recycling asphalt in the short term. Now he and his team are trying to improve the long-term performance of the recycled asphalt pavement (RAP) material containing these oils. (8/4/21)

Lu team develop method to guard carbon fiber against oxidation

Yongfeng Lu Yongfeng Lu and colleagues have developed a low-cost, scalable method of protecting carbon fibers from oxidation when exposed to extreme temperatures. They found that dipping carbon fibers into a molten salt mixture containing titanium and chromium powders triggers a spontaneous reaction that leaves the fibers with a three-layer protective coating. The coated carbon fibers remained undamaged when exposed to 2,200 degrees Fahrenheit and extreme environmental conditions simulated with an oxyacetylene flame. Bai Cui is also involved in this research. (7/26/21)

Sellmyer honored with endowed chair

John Woollam on left and David Sellmyer on right. David Sellmyer has been recognized for his achievements at Nebraska with an endowed faculty chair named in his honor. The David J. Sellmyer Chair in Condensed Matter Physics was established with a gift from John Woollam to the University of Nebraska Foundation. The Sellmyer Chair will be used to recruit faculty members with a strong publication record, proven effectiveness in building experimental collaborations, and success in securing collaborative grants. Additionally, the chair holder will grow the stature of the condensed-matter physics program, be dedicated to mentoring graduate students, and promote excellent physics education at all levels.
