Functional role of water in membranes updated: A tribute to Träuble [PDF]
, 2015 The classical view of a cell membrane is as a hydrophobic slab in which only nonpolar solutes can dissolve and permeate. However, water-soluble non-electrolytes such as glycerol, erythritol, urea and others can permeate lipid membranes in the liquid ...

Understanding the interaction between a steel microstructure and hydrogen [PDF]
, 2018 The present work provides an overview of the work on the interaction between hydrogen (H) and the steel’s microstructure. Different techniques are used to evaluate the H-induced damage phenomena. The impact of H charging on multiphase high-strength

Reduced complexity models for water management and anode purge scheduling in DEA operation of PEMFCs [PDF]
, 2010 In this work, the dynamic behavior of Fuel Cell operation under Dead-Ended Anode conditions is shown. A DEA can be fed with dry hydrogen, since water crossing through the membrane is sufficient to humidify the fuel.

Use of nanoporous ceramic membranes for carbon dioxide separation [PDF]
, 2016 Natural gas processes accounts for about 5.3 billion tonnes per year of carbon dioxide (CO2) emission to the atmosphere. At this rate of emission, the expectation will drastically rise if not curtailed.
