Polymers Derived from Bio-diesel Waste for Road Dust Control
Scientists at NDSU have developed a new material that can be applied to gravel roads for the suppression of road dust. The material is made from the huge waste stream that is generated during the production of biodiesel, which is primarily glycerol and biodegradable or bio-derived fatty acid esters. The new material is made up of mono- and di-glycerides...

Biobased Cyclic Carbonate Functional Resins and Polyurethane Thermosets Therefrom
This technology introduces a sustainable, non-isocyanate route to producing high-performance polyurethane materials using bio-derived feedstocks. By converting epoxidized natural oils, such as epoxidized sucrose soyate, into cyclic carbonate-functional resins via reaction with carbon dioxide, the system replaces toxic isocyanates with multifunctional...

Automated Ice Adhesion Measurement Tool
This custom-built apparatus measures the ice adhesion strength of coating panels in shear mode. In a single run, up to 30 test panels can be tested, with two measurements taken for each panel, resulting in 60 ice adhesion measurements per run. Allowing for a maximum of 180 measurements conducted in one day. The system becomes fully automated after the...

High Throughput Array-Based Ice Adhesion Screening Apparatus
This machine measures ice adhesion by pushing a small ice mold frozen onto a coated test panel. Each panel contains 48 shallow wells, each holding 20 microliters of coating. The system features two actively cooled trays. Each tray holds a 48-well array plate. The chilled shelf ensures ice forms at the coating surface and grows upward. With 96 test sites...
