Synopsis: Research teams that pursue convergence will confront a variety of difficulties. To help identify and cope with some of these difficulties, NSF has assembled a panel of experts who have led large research centers, and so have experience with convergence at a variety of scales. Whether it’s a single science team, a team of teams, or an entire research center, our panelists have gleaned insights from years of experience catalyzing convergence.

Synopsis: The complexity of scientific problems, coupled with a growing need for specialized expertise, requires the formation of teams of experts who collaborate across disciplinary boundaries to generate scientific breakthroughs. The variety of knowledge available in convergence science teams provides the breadth of expertise to tackle complex problems that would be intractable by a single discipline. This presentation demonstrates the use of formal interventions to support early-stage discovery collaborations focused on curing devastating diseases. To advance their objectives, these collaborations must overcome profound differences in members' specialized knowledge while simultaneously having little familiarity and limited prior histories of collaboration with one another to build from.

Synopsis: The United States is caught in a disaster loss spiral. The increasing frequency and intensity of disasters, coupled with the growth of the field of disaster research, suggests an urgent need for a more coherent convergence-oriented approach to help guide what we study, who we study, how we conduct studies, and who is involved in the research process itself. The NSF-funded CONVERGE facility—which was established in 2018 as the first social science-led component of the Natural Hazards Engineering Research Infrastructure (NHERI)—advances convergence research for the hazards and disaster community. This presentation describes the activities of CONVERGE and showcases the various available resources such as online training modules, research check sheets, and convergence research agendas. It also highlights how CONVERGE is building the social infrastructure that brings together networks of researchers from geotechnical engineering, the social sciences, structural engineering, nearshore science, operations and systems engineering, environmental engineering, and interdisciplinary science and engineering.

Synopsis: Convergence trends have been inherent in knowledge and human development. Convergence is a problem-solving strategy to holistically understand and transform a system for reaching a compelling common goal, such as advancing an emerging technology in society. The convergence approach typically begins with deep integration of previously separate fields, communities, and modes of thinking, to form and improve a new system, from where solutions diverge to previously unattainable applications and outcomes. Basic principles and methods to facilitate convergence and examples of their application were presented.
The incentive to reduce greenhouse gas emissions has motivated the development of lignocellulosic biomass conversion technologies, especially those associated with the carbohydrate fraction. An interdisciplinary collaboration between experimental and computational teams at the University of Delaware, have provided the first integrated process and life cycle greenhouse gas model to evaluate different tree parts in a biorefinery operation that generates polymer precursors and biochemicals.
The biorefinery concept has been proposed to reduce waste and generate an array of products from all input components for the efficient use of bio-derived raw materials. It has the potential to improve the environmental performance and economic viability of biomass conversion facilities. The proposed biorefinery integrates reductive catalytic fractionation, molten salt hydrolysis, and waste solids combustion for energy.
This is the first study to include different tree parts and their variable lignin chemistries in an LCA (life cycle assessment). All three forest residuals and their mix emit less greenhouse gas than the incumbent oil-based chemical production technologies. Using twigs and branchlets as the biorefinery feedstock has the lowest life-cycle greenhouse gas emission.
Carbon sequestration and utility generated from unreacted waste combustion are the main benefits of using biomass feedstock. This work provides simulation and evaluation platform for other feedstocks (compositions and RCF (reductive catalytic fractionation) yields) used in biorefineries.
This research provides the first integrated process and life cycle greenhouse gas model to evaluate different tree parts in a biorefinery operation that generates polymer precursors and biochemicals, while demonstrating that different forest residues (both individually and as a composite mix) could be utilized in a yellow poplar biorefinery to significantly reduce the greenhouse gas emissions vs. a petroleum-based process.
