Activating dinitrogen for chemical looping ammonia Synthesis: Mn nitride layer growth modeling
(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 ... -
Activating dinitrogen for chemical looping ammonia synthesis: nitridation of manganese
(Journal of Materials Science, 2021-04-23)The earth-abundant transition metal manganese (Mn) has been shown to be useful to activate dinitrogen at atmospheric pressure and elevated temperature by forming bulk Mn nitrides. Mn nitrides could then be used, for example, ... -
Relating agriculture, energy, and water decisions to farm incomes and climate projections using two freeware programs, FEWCalc and DSSAT
(Agricultural Systems, 2021-10)Context: The larger scale perspective of Integrated Assessment (IA) and smaller scale perspective of Impacts, Adaptation, and Vulnerability (IAV) need to be bridged to design long-term solutions to agricultural problems ... -
Consequences of climate change on food-energy-water systems in arid regions without agricultural adaptation, analyzed using FEWCalc and DSSAT
(Resources, Conservation and Recycling, 2021-05)Effects of a changing climate on agricultural system productivity are poorly understood, and likely to be met with as yet undefined agricultural adaptations by farmers and associated business and governmental entities. The ... -
Chemical Looping of Manganese to Synthesize Ammonia at Atmospheric Pressure: Sodium as Promoter
(Chemical Engineering & Technology, 2020-08-10)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 ... -
Resilience and technological diversity in smart homes
(Journal of Ambient Intelligence and Humanized Computing, 2020)This article introduces our abstract modeling strategy to represent the general features and topology of the kinds of integrated and technologically diverse networks that feature in IoT systems. We begin with smart home ... -
Intelligent Systems for Geosciences: An Essential Research Agenda
(Communications of the ACM, 2019-01)A research agenda for intelligent systems that will result in fundamental new capabilities for understanding the Earth system. Many aspects of geosciences pose novel problems for intelligent systems research. Geoscience ... -
A wedge or a weight? Critically examining nuclear power’s viability as a low carbon energy source from an intergenerational perspective
(Energy Research & Social Science, 2019-04)Some integrated assessment studies of climate change have concluded that nuclear energy has a large potential impact on carbon abatement costs. However, these studies have often modeled the cost of nuclear waste management ... -
Beyond fossil fuel–driven nitrogen transformations
(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
(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
(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
(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
(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
(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
(Culture, Agriculture, Food and Environment, 2013)Climate change and industrial agricultural practices pose threats to the future of Kansas agriculture. To inform the debate about sustainable agriculture that must soon occur, we seek to illuminate the factors involved in ... -
Solar thermochemical production of ammonia from water, air and sunlight: Thermodynamic and economic analyses
(Energy, 2012-06)Ammonia is an important input into agriculture and is used widely as base chemical for the chemical industry. It has recently been proposed as a sustainable transportation fuel and convenient one-way hydrogen carrier. ... -
Sustainability of algae derived biodiesel: A mass balance approach
(Bioresource Technology, 2011-01)A rigorous chemical engineering mass balance/unit operations approach is applied here to bio-diesel from algae mass culture. An equivalent of 50,000,000 gallons per year (0.006002 m3/s) of petroleum-based Number 2 fuel ... -
Bio-butanol vs. bio-ethanol: A technical and economic assessment for corn and switchgrass fermented by yeast or Clostridium acetobutylicum
(Biomass and Bioenergy, 2010-04)Fermentation-derived butanol is a possible alternative to ethanol as a fungible biomass-based liquid transportation fuel. We compare the fermentation-based production of n-butanol vs. ethanol from corn or switchgrass through ...
