Gas crossover mitigation in PEM water electrolysis: hydrogen cross-over benchmark study of 3M's Ir-NSTF based electrolysis catalyst-coated membranes
(ECS, 2016)
In this work we present some preliminary data, such as permeability (gas crossover) of oxygen and hydrogen as a function of current density and other operational variables, aimed at establishing baselines for unmitigated ...
LQ control for coordinated linear systems
(IEEE, 2014)
Coordinated linear systems are a special class of hierarchical
linear systems, with a strict top-to-bottom information
structure. The LQ problem over all structure-preserving static
state feedbacks is discussed. The ...
A systems engineering approach for the deployment of an atmospheric monitoring station
(Wiley, 2014)
In this paper the importance of a Systems Engineering (SE) approach is reiterated for developing and managing an atmospheric monitoring station. A newly established comprehensive atmospheric monitoring station, the Welgegund ...
Reducing atmosphere ash fusion temperatures of amixture of coal-associated minerals: the effect of inorganic additives and ashing temperature
(Elsevier, 2014)
The influence of the ashing temperature and inorganic additives on the reducing-atmosphere ash fusion temperatures of a mixture of coal-associated minerals was investigated. Different inorganic compounds were added to the ...
Experimental performance evaluation of an ammonia-fuelled microchannel reformer for hydrogen generation
(Elsevier, 2014)
Microchannel reactors appear attractive as integral parts of fuel processors to generate hydrogen (H2) for portable and distributed fuel cell applications. The work described in this paper evaluates, characterizes, and ...
Establishing suitable conditions for metals recovery from metal saturated Bacillaceae bacterium using experimental design
(Elsevier, 2014)
In this study the response surface methodology (RSM) based on the Box-Behnken design model was applied to investigate the effect of parameter interactions that are suspected to influence the metal desorption process. The ...
Optimisation of deep burn incineration of reactor waste plutonium ina PBMR DPP-400 core
(Elsevier, 2014)
In this article an original set of coupled neutronics and thermo-hydraulic simulation results for the VSOP 99/05 diffusion code are presented for advanced fuel cycles for the incineration of weapons-grade plutonium, ...
Effect of Saccharomyces cerevisiae and Zymomonas mobilis on the co-fermentation of sweet sorghum bagasse hydrolysates pretreated under varying conditions
(Elsevier, 2014)
Hydrolysates from sweet sorghum bagasse pretreatment normally contains hexose and pentose sugars, and this complex mixture of sugars presents a challenge for a single microorganism to effectively ferment all sugars to ...
Semi-empirical model for limestone dissolution in adipic acid for wet flue gas desulfurization
(Wiley-VCH Verlag, 2014)
Wet flue gas desulfurization systems are commonly applied to remove sulfur
dioxide by contacting it with limestone in an aqueous phase. The effects of pH,
stirring speed, solid-to-liquid ratio, acid concentration, and ...
Influence of reaction atmosphere and solvent on biochar yield and characteristics
(Elsevier, 2014)
Sunflower husks were converted to biochar via thermochemical liquefaction in different solvents and reaction atmospheres. Highest biochar yields obtained was 574 g kg−1 husks. Surface area of the produced chars and evolution ...
