“…The concern expressed by Spahiu and Puigdomenech was that our estimated corrosion rate is around three orders of magnitude higher than that derived from the observations published by Hultquist et al 2,3 This discrepancy may be readily understood by recognizing that the approach to the equilibrium condition is governed by kinetic parameters such as rate constants, mass-transfer coefficients, and the electrode area to volume ratio. To explore the influence of system parameters, the simulations presented in our paper 1 were extended to include the oxidation of hydrogen and diffusion of dissolved hydrogen away from the electrode surface.…”

“…Spahiu and Puigdomenech suggest that trace amounts of oxygen in the experiment may be sufficient to explain the derived corrosion rates from the experiments performed; 3. Spahiu and Puigdomenech express concern that the observed corrosion rate by Cleveland et al 1 is around three orders of magnitude higher than the rate that may be derived from the observations published by Hultquist et al 2,3 From these criticisms, Spahiu and Puigdomenech posit that our work 1 "may not be considered to support the claim that copper will corrode in deaerated deionized water if hydrogen is removed." Our response to these critiques are presented below.…”

“…Mass-transfer coefficients.-Mass-transfer coefficients were obtained from published correlations for the microelectrode used in our work 1 and the copper foils used in the work by Hultquist et al 2 The relationship between the mass-transfer coefficient for cupric ions and dissolved hydrogen differed for the two cases because transport for the microelectrode was assumed to be controlled by diffusion and transport for the foils was assumed to be controlled by natural convection.…”

“…Hultquist foils.-The experimental systems reported by Hultquist et al 2 consisted of copper foils with an exposed area of 85 cm 2 placed upright in a sealed vessel and immersed in anoxic water with a volume of 50 cm 3 . Such a system may be expected to be driven by natural convection.…”

This response is provided to comments by Spahiu and Puigdomenech criticizing the conclusion of Cleveland et al. [J. Electrochem. Soc., 161, C107 (2014)] that, in the absence of hydrogen, copper will corrode in deaerated deionized water. Spahiu and Puigdomenech base their critique on anomalies in the Pourbaix diagram presented by Cleveland et al., on concerns that the experimental system was inadequately deaerated, and on differences between the corrosion rates predicted in our work and in the work of Hultquist et al.

Radiation Effects on Materials Used in Geological Repositories for Spent Nuclear Fuel

Safe long-term storage of radioactive waste from nuclear power plants is one of the main concerns for the nuclear industry as well as for governments in countries relying on electricity produced by nuclear power. A repository for spent nuclear fuel must be safe for extremely long time periods (at least 100 000 years). In order to ascertain the long-term safety of a repository, extensive safety analysis must be performed. One of the critical issues in a safety analysis is the long-term integrity of the barrier materials used in the repository. Ionizing radiation from the spent nuclear constitutes one of the many parameters that need to be accounted for. In this paper, the effects of ionizing radiation on the integrity of different materials used in a granitic deep geological repository for spent nuclear fuel designed according to the Swedish KBS-3 model are discussed. The discussion is primarily focused on radiationinduced processes at the interface between groundwater and solid materials. The materials that are discussed are the spent nuclear fuel (based on UO 2 ), the copper-covered iron canister, and bentonite clay. The latter two constitute the engineered barriers of the repository.

Surface Adsorption of Polyethylene Glycol to Suppress Dendrite Formation on Zinc Anodes in Rechargeable Aqueous Batteries

et al. 2018

Aqueous metal batteries routinely suffer from the dendritic growth at the anode, leading to significant capacity fading and ultimately, battery failure from short‐circuit. Herein, we utilize polyethylene glycol to regulate dendrite growth and improve the long‐term cycling stability of an aqueous rechargeable lithium/zinc battery. PEG200 in the electrolyte decreases the corrosion and chronoamperometric current densities of the zinc electrode up to four‐fold. Batteries with pre‐grown dendrites also perform significantly better when PEG is present in the electrolyte (41.4 mAh g−1 vs. 7.9 mAh g−1 after 1000 cycles). X‐ray diffraction and electron microscopy studies show that dendrites in the PEG‐containing electrolyte have been inhibited, leading to much smaller/smoother surface features than those of the control. The facile preparation process of the aqueous electrolyte combined with low cost and vast performance improvement in batteries of all sizes indicates high upscaling viability.
