3D printed and stimulus responsive drug delivery systems based on synthetic polyelectrolyte hydrogels manufactured via digital light processing

Vaupel, Sonja; Mau, Robert; Kara, Selin; Seitz, Hermann; Kragl, Udo; Meyer, Johanna (London [u.a.] : RSC, 2023)

Hydrogels are three-dimensional hydrophilic polymeric networks absorbing up to and even more than 90 wt% of water. These superabsorbent polymers retain their shape during the swelling process while enlarging their volume ...
The Effect of Cell Compression and Cathode Pressure on Hydrogen Crossover in PEM Water Electrolysis

Martin, Agate; Trinke, Patrick; Stähler, Markus; Stähler, Andrea; Scheepers, Fabian; Bensmann, Boris; Carmo, Marcelo; Lehnert, Werner; Hanke-Rauschenbach, Richard (Bristol : IOP Publishing, 2022)

Hydrogen crossover poses a crucial issue for polymer electrolyte membrane (PEM) water electrolysers in terms of safe operation and efficiency losses, especially at increased hydrogen pressures. Besides the impact of external ...
Elucidating the effect of mass transport resistances on hydrogen crossover and cell performance in PEM water electrolyzers by varying the cathode ionomer content

Trinke, P.; Keeley, G.P.; Carmo, M.; Bensmann, B.; Hanke-Rauschenbach, R. (Bristol : IOP Publishing Ltd., 2019)

An important challenge for polymer electrolyte membrane (PEM) water electrolysis is to reduce the permeation of the produced gases. This crossover affects the cell efficiency and causes safety issues. The crossover increases ...
Hydrogen Crossover in PEM Water Electrolysis at Current Densities up to 10 A cm−2

Martin, Agate; Trinke, Patrick; Bensmann, Boris; Hanke-Rauschenbach, Richard (Bristol : IOP Publishing, 2022)

Hydrogen crossover poses a critical issue in terms of the safe and efficient operation in polymer electrolyte membrane water electrolysis (PEMWE). The impact of key operating parameters such as temperature and pressure on ...
