About

James E. Miller (Jim) is a chemical engineer who has directed his efforts towards energy, materials, and chemical processing research. Prior to joining ASU LightWorks® in 2018, he worked at Sandia National Laboratories for over 25 years where his work touched on diverse topics ranging from catalysis for a variety of reactions to desalination. He served as the principal investigator of large multi-institution and multi-discipline efforts focused on solar thermochemical processes for solar fuels (Sunshine to Petrol) and thermochemical energy storage (PROMOTES). His contributions include materials development and characterization, development of new high-temperature thermochemical reactors and systems, and thermodynamic, engineering, and technoeconomic analysis. Dr. Miller has co-authored over 130 technical documents, holds 18 patents, and is the recipient of two R&D 100 Awards. His research has involved developing and characterizing chemical processes and active materials, including catalysts for partial oxidation of hydrocarbons, catalytic combustion components, radioactive waste treatment technologies, catalytic hydrotreating and hydrocracking of coal and petroleum liquids, lignin depolymerization, desalination technologies, exhaust gas aftertreatment materials, and nanostructured platinum materials for catalytic applications. In recent years, his focus has been largely directed towards metal-oxide based solar thermochemistry for synthetic fuel production from carbon dioxide…

• Parachute conservation: Investigating trends in international research

  Conservation Letters · 2023-03-13 · 41 citations

  articleOpen access1st author

  Abstract Parachute science (inequity in research relationships between Global North and South scientists) has known detrimental impacts on Global South researchers in conservation. Using two international datasets of English and non‐English‐language studies testing conservation interventions, we compared the continents in which studies were conducted to those in which authors were affiliated. We found that a substantial proportion of English‐language studies conducted in Global South continents…

• Towards chemical equilibrium in thermochemical water splitting. Part 2: Re-oxidation

  International Journal of Hydrogen Energy · 2024-06-01 · 8 citations

  articleOpen access

  Chemical equilibrium represents the highest efficiency achievable by a thermochemical cycle under specific operational conditions. This study delves into two-step thermochemical water splitting cycles, which dissociate water into hydrogen (H2) and oxygen (O2) via sequential thermal reduction and re-oxidation processes. Building on the thermal reduction analysis presented in Part 1, this paper zeroes in on the re-oxidation reaction within the optimal reactor framework – the counter-current reacto…

• Two‐Step Chemical Looping Cycle for Renewable NH₃ Production Based on Non‐Catalytic Co₃Mo₃N/Co₆Mo₆N Reactions

  Advanced Energy Materials · 2023-12-11 · 4 citations

  articleOpen access

  Abstract A two‐step solar thermochemical looping cycle based on Co 3 Mo 3 N/Co 6 Mo 6 N reduction/nitridation reactions offers a pathway for green NH 3 production that utilizes concentrated solar irradiation, H 2 O, and air as feedstocks. The NH 3 production cycle steps both derive process heat from concentrated solar irradiation and encompass 1) the reduction of Co 3 Mo 3 N in H 2 to Co 6 Mo 6 N and NH 3 ; and 2) nitridation of Co 6 Mo 6 N to Co 3 Mo 3 N with N 2 . Co 3 Mo 3 N reduction/nitrida…

• Exploring the Role of Duddingtonia flagrans in Integrated Parasite Management: A Systematic Review of Current Research and Applications

  Preprints.org · 2025-02-17 · 2 citations

  reviewOpen access

  Nematophagous fungi, particularly Duddingtonia flagrans, provide a sustainable and environmentally friendly alternative to chemical anthelmintics for controlling gastrointestinal nematodes (GIN) in livestock. With the increasing prevalence of GIN resistance to anthelmintic drugs, alternative control strategies are essential for maintaining livestock health and productivity. Duddingtonia flagrans has demonstrated efficacy in reducing pasture contamination by trapping and eliminating nematode larv…
