      <title>Structure Dynamics-Guided Biocatalyst Improvement</title>
      <link>https://rip.trb.org/View/1363824</link>
      <description><![CDATA[The success in the proposed research will open a new chapter in biocatalyst improvement and greatly benefit the biorefinery industry with three folds. First, the project team will deliver a novel platform using Hydrogen Deuterium Exchange (HDX) mass spectrometry for biocatalyst improvement, and the platform can be used for enzyme improvement of various purposes. Second, the team will be able to deliver some biocatalysts with higher efficiency and better inhibitor resistance. These biocatalysts will help to improve the biorefinery procedure and biomass conversion efficiency tremendously. Third, the proposed research will help to elucidate the molecular mechanisms for the cellulase enzyme catalysis and inhibition from the dynamic perspectives, which will guide the future enzyme improvement.]]></description>

      <title>Sustainable Asphalt Pavements Using Bio-Binders from Bio-Fuel Waste</title>
      <link>https://rip.trb.org/View/1265565</link>
      <description><![CDATA[The vast majority of asphalt materials used in highway construction are currently derived from the distillation of crude petroleum. The increasing demand for products derived from crude petroleum, coupled with constrained supply, has led to substantial price increases in crude petroleum products including asphalt. To further meet the increased demand for transportation fuels, many refineries have installed coking facilities that remove asphalt from the marketplace, further impacting the pricing of asphalt. The evolution of the biorefineries producing transportation fuels, specialty chemical products and food products has created opportunities for using derived co-products in the asphalt industry. These co-products may be used to either partially or fully replace crude petroleum-derived asphalt, or be used as beneficial additives for mitigating moisture damage as an example. Assessment and characterization of these materials, including chemical compatibility, rheological testing and formulation for use in asphalt paving, is needed. This project is a collaborative one combining Kansas State University's expertise in analytical chemistry and asphalt mixture characterization with Iowa State University's expertise in using bio-based materials in asphalt materials and rheological characterization. This project addresses the United States Department of Transportation's strategic goals associated with state of good repair, sustainability, and economic competitiveness.]]></description>
