POM‐Based Water Splitting Catalyst Under Acid Conditions Driven by Its Assembly on Carbon Nanotubes
Advanced Materials, EarlyView.A newly‐engineered POM‐based electrocatalyst incorporating non‐innocent counter cations exhibits fast kinetics for either the OER or HER under strongly acidic conditions (1 m H2SO4), depending on whether it is assembled on carbon nanotubes (1@CNT) or physically mixed with them (1/CNT). In water‐splitting tests using a two‐electrode setup, these systems

Hydrogen and moisture-induced scale spallation: Cathodic descaling of a single crystal superalloy [PDF]
, 2011 Moisture-induced delayed spallation (MIDS) of protective alumina scales at room temperature is a well known phenomenon. One mechanism proposes that water and Alalloy react, produce hydrogen at the scale–metal interface, and enable spallation.

Effect of Microstructure and Space Charge on Cathodic Polarization
ECS Proceedings Volumes, 2005 Bar-shaped samples of porous samaria-doped ceria (SDC) with large neck sizes were fabricated using a three-step method. In the first step, two phase samples containing NiO + SDC were fabricated by sintering powder compacts. In the second step, NiO was reduced to Ni at 800°C in a hydrogen-containing atmosphere.

Ion‐Reconfigurable “N”‐Shaped Antiambipolar Behavior in Organic Electrochemical Transistors
Advanced Materials, EarlyView.A unique N‐shaped negative differential transconductance (NDT) characteristics is demonstrated in single‐polymer organic electrochemical transistors through a sequential doping–redox–doping process driven by iodide ions. This redox‐driven mechanism enables low‐voltage, ion‐controlled reconfigurability and tunable current modulation, allowing seamless ...
