Synthesis of silicon doped SrMO3 (M=Mn, Co): stabilization of the cubic perovskite and enhancement in conductivity [PDF]
, 2011 In this paper we report the successful incorporation of silicon into SrMO3 (M=Co, Mn) leading to a structural change from a hexagonal to a cubic perovskite.

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.Green, non‐toxic DMM selectively adsorbs on the zinc surface, restructuring the inner Helmholtz layer and forming a water‐lean interface that inhibits direct water‐zinc contact. Typically, advanced quartz crystal microbalance precisely quantifies this adsorption.

Diffusion-Related SOFC Stack Degradation [PDF]
ECS Meeting Abstracts, 2017 Solid Oxide Fuel Cell systems for stationary applications should exhibit low degradation (<< 1%/1,000h voltage loss) to ensure long-term operation (> 40,000h). The rather high operation temperature of SOFCs (≥ 700°C) is on the one hand beneficial for oxygen conduction through the ceramic-based electrolyte, but on the other hand all diffusion-
