McKrell was a prolific contributor to a diverse range of other subjects, including the study of oxidation of Accident Tolerant Fuel (ATF) for nuclear reactors, the mitigation of tube fouling in geothermal power systems, and the probing of fundamental mechanisms in boiling heat transfer using advanced infra-red diagnostics.
The Wuhan researchers created an anode coated with nickel nanoparticles decorated with chromium that's more tolerant to oxidation than previous nickel catalysts.
We discuss the underlying molecular mechanisms responsible for the enhanced stability of the anodes and propose a number of guiding principles for the design of carbon-tolerant anodes for oxidation of oxygenated hydrocarbons.
SiC-SiC composites exhibit exceptional high temperature strength and oxidation properties making them an advantageous choice for accident tolerant nuclear fuel cladding.
In addition to the high activity for the reforming and electrochemical oxidation of fuel, the anode is required to be tolerant to the carbon deposition formed by the decomposition of hydrocarbon fuels.
In regard to stability, the cytosolic enzymes GS1.2 and GS1.3 were much more tolerant to thermal inactivation and metal-catalyzed oxidation than GS1.1.
Since the PdxCo/C alloy electrocatalysts are inactive for the adsorption and oxidation of methanol, it can act as a methanol-tolerant ORR catalyst in a direct methanol fuel cell (DMFC).
Pd3Pt1/MSU-F-C is methanol tolerant at 400 rpm in the presence of 0.5 M CH3OH, while methanol oxidation peaks are observed in the case of Pd3Pt1/Vulcan XC-72 and Pd3Pt1/CMK-3.
Silicon carbide (SiC) is being investigated for accident tolerant fuel cladding applications due to its high temperature strength, exceptional stability under irradiation, and reduced oxidation compared to Zircaloy under accident conditions.
Three general strategies for accident tolerant fuels are being explored: modification of current state-of-the-art zirconium alloy cladding to further improve oxidation resistance (including use of coatings), replacement of Zr alloy cladding with an alternative oxidation-resistant high-performance cladding, and replacement of the monolithic ceramic oxide fuel with alternative fuel forms.
