Free-Energy Analysis of Bubble Nucleation on Electrocatalytic Surfaces
Qingguang Xie, Paolo Malgaretti, Othmane Aouane +2
Bubble nucleation at catalyst surfaces plays a critical role in the operation of electrolyzers. However, achieving controlled bubble nucleation remains challenging due to limited u…
How back reaction, hydrogen transport, and capillarity control the performance of hydrogen release from liquid organic carriers
Tatiana Nizkaia, Thomas Solymosi, Paolo Malgaretti +2
We derive a theoretical model to elucidate the inhibition of catalytic activity during the dehydrogenation of Liquid Organic Hydrogen Carriers (LOHC). Within our model, we account…
Spontaneous Emergence of Solitary Waves in Active Flow Networks with Elastic Elements
Rodrigo Fernández-Quevedo GarcÃa, Gonçalo Cruz Antunes, Jens Harting +6
Flow networks are fundamental for understanding systems such as animal and plant vasculature or power distribution grids. These networks can encode, transmit, and transform informa…
Zigzagging Diffusion and Non-Standard Transport in Particle-laden Nanopores Under Extreme Confinement
A. Baer, P. Malgaretti, K. Hoellring +2
Understanding transport subject to molecular-scale confinement is key to advancing nanofluidics, yet classical hydrodynamic laws often fail at these scales. Here, we study a model…
Modelling of the dewetting of ultra-thin liquid films on chemically patterned substrates: linear spectrum and deposition patterns
Tilman Richter, Paolo Malgaretti, Jens Harting
Liquid films of nanometric thickness are prone to spinodal dewetting driven by disjoining pressure, meaning that a non-wetting liquid film of homogeneous thickness in the range of…
Transport of electrolytes across nanochannels: the role of slip
F. Carusela, J. Harting, P. Malgaretti
We characterize the electrokinetic flow due to the transport of electrolytes embedded in nanochannels of varying cross-section with inhomogeneous slip on their walls, modeled as an…
