Graphene Multi-Protonation: a Cooperative Mechanism for Proton Permeation

, 2018
The interaction between protons and graphene is attracting a large interest due to recent experiments showing that these charged species permeate through the 2D material following a low barrier (~ 0.8 eV) activated process.

Microstructural development, electrical properties and oxygen permeation of zirconia-palladium composites [PDF]

, 1995
Yttria-stabilized cubic zirconia (YSZ)-palladium dual phase composites have been investigated. The percolative composite containing 40 vol% Pd (ZYPd40) showed a much larger oxygen permeability than that of the non-percolative composite containing 30 vol%

Spectrally Tunable 2D Material‐Based Infrared Photodetectors for Intelligent Optoelectronics

Advanced Functional Materials, EarlyView.
Intelligent optoelectronics through spectral engineering of 2D material‐based infrared photodetectors. Abstract The evolution of intelligent optoelectronic systems is driven by artificial intelligence (AI). However, their practical realization hinges on the ability to dynamically capture and process optical signals across a broad infrared (IR) spectrum.

Permeation of Hydrogen in Palladium

Materials Transactions, JIM, 1993
Experimental studies on the permeation of hydrogen in a palladium plate 1-2×10 -4 m in thickness were carried out at a constant temperature under the application of a constant hydrogen pressure in the respective ranges from 261 to 191 K and from 66.5 to 2660 Pa. Hydrogen permeabilities obtained in the permeation experiment are expressed by the formula
