Electrode Performance in Reversible Solid Oxide Fuel Cells
Olga A. Marina,Larry R. Pederson,Mark C. Williams,Greg W. Coffey,Kerry D. Meinhardt,Carolyn D. Nguyen,Ed Thomsen +6 more
TL;DR: In this article, the authors proposed a reversible fuel cell, which is capable of operating both as a fuel cell and as an electrolyzer, although the fuel cells and electrolyzer functions are carried out in separate subsystems.
Highly active and stable ruthenate pyrochlore for enhanced oxygen evolution reaction in acidic medium electrolysis
Qi Feng,Qi Feng,Qi Wang,Zhen Zhang,Zhen Zhang,Yongyueheng Xiong,Hanyi Li,Yao Yao,Xiao-Zi Yuan,Mark C. Williams,Meng Gu,Hong Chen,Hui Li,Haijiang Wang +13 more
TL;DR: In this paper, a site doped yttrium ruthenate pyrochlore oxides (Y1.85Zn0.15Ru2O7−δ) was developed for oxygen evolution reaction (OER).

Characterization of the wettability of solid particles by film flotation 1. Experimental investigation
TL;DR: In this paper, a technique called film flotation is used for assessing the wetting characteristics of particulates, where particles placed onto the surface of a liquid are imbibed into the liquid only when their critical wetting surface tension is equal to or higher than the surface tension of the liquid.

Influence of Surface Oxygen Vacancies and Ruthenium Valence State on the Catalysis of Pyrochlore Oxides
Qi Feng,Qi Feng,Jiexin Zou,Wang Yajun,Zhi Liang Zhao,Mark C. Williams,Hui Li,Hui Li,Wang Haijiang +8 more
TL;DR: It is revealed that partially replacing Y3+ by Ba2+ in Y2Ru2O7 greatly facilitates the hole-doping effect, which generates massive oxygen vacancy and multivalence of Ru5+/Ru4+, thus boosting the OER performance of Y2-xBaxRu 2O7.
