  • Activating dinitrogen for chemical looping ammonia Synthesis: Mn nitride layer growth modeling 

    Aframehr, Wrya Mohammadi; Pfromm, Peter H. (Chemical Engineering Science, 2022-04-28)
    The earth-abundant transition metal manganese (Mn) has been shown to activate dinitrogen (N2) and store nitrogen (N) as nitride for subsequent chemical reaction, for example, to produce ammonia (NH3). Chemical looping ...

    Affordable synthetic ammonia (NH3) enables the production of nearly half of the food we eat and is emerging as a renewable energy carrier. Sodium-promoted chemical looping NH3 synthesis at atmospheric pressure using manganese ...
  • Beyond fossil fuel–driven nitrogen transformations 

    Chen, Jingguang G.; Crooks, Richard M.; Seefeldt, Lance C.; Bren, Kara L.; Bullock, R. Morris; Darensbourg, Marcetta Y.; Holland, Patrick L.; Hoffman, Brian; Janik, Michael J.; Jones, Anne K.; Kanatzidis, Mercouri G.; King, Paul; Lancaster, Kyle M.; Lymar, Sergei V.; Pfromm, Peter H.; Schneider, William F.; Schrock, Richard R. (Science, 2018-05-25)
    How much carbon does it take to make nitric acid? The counterintuitive answer nowadays is quite a lot. Nitric acid is manufactured by ammonia oxidation, and all the hydrogen to make ammonia via the Haber-Bosch process comes ...
  • Towards sustainable agriculture: Fossil-free ammonia 

    Pfromm, Peter H. (Journal of Renewable and Sustainable Energy, 2016-12-28)
    About 40% of our food would not exist without synthetic ammonia (NH3) for fertilization. Yet, NH3 production is energy intensive. About 2% of the world's commercial energy is consumed as fossil fuels for NH3 synthesis based ...
  • Legitimate to whom? The challenge of audience diversity and new venture legitimacy 

    Fisher, Greg; Kuratko, Donald F.; Bloodgood, James M.; Hornsby, Jeffrey S. (Journal of Business Venturing, 2017-01)
    We examine how entrepreneurs manage new venture legitimacy judgments across diverse audiences, so as to appear legitimate to the different audience groups that provide much needed financial resources for venture survival ...
  • The role of network density and betweenness centrality in diffusing new venture legitimacy: an epidemiological approach 

    Bloodgood, James M.; Hornsby, Jeffrey S.; Rutherford, Matthew; McFarland, Richard G. (International Entrepreneurship and Management Journal, 2017)
    To survive and grow, new ventures must establish initial legitimacy, and subsequently diffuse this legitimacy through a given population. While the notion of initial legitimacy has received substantial attention in the ...
  • Regulating the Ogallala: Paradox and Ambiguity in Western Kansas 

    Gibson, Jane W.; Gray, Benjamin Jerome (The Economics of Ecology, Exchange, and Adaptation: Anthropological Explorations, 2016-09-01)
    Purpose: To illuminate the underlying logic of western Kansas farmers’ decisions to irrigate at unsustainable rates and the state’s regulatory policies and practices that enable depletion of the Ogallala aquifer. Meth ...
  • Economic feasibility of algal biodiesel under alternative public policies 

    Amanor-Boadu, Vincent; Pfromm, Peter H.; Nelson, Richard (Renewable Energy, 2014-07)
    The motivation for this research was to determine the influence of public policies on economic feasibility of producing algal biodiesel in a system that produced all its energy needs internally. To achieve this, a steady-state ...
  • Actor–Networks, Farmer Decisions, and Identity 

    Gray, Benjamin Jerome; Gibson, Jane W. (Culture, Agriculture, Food and Environment, 2013)
