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…
Effects of Hydrogen Transport on the Kinetic Regimes of 4-Nitrophenol Reduction by Sodium Borohydride
Tatiana Nizkaia, Philipp Groppe, Valentin Müller +3
The reduction of 4-nitrophenol (4-NiP) with sodium borohydride is widely used to benchmark heterogeneous catalysts, yet its kinetics are commonly oversimplified as pseudo-first-ord…
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…
Mechanical work extraction from an error-prone active dynamic Szilard engine
Luca Cocconi, Paolo Malgaretti, Holger Stark
Isothermal information engines operate by extracting net work from a single heat bath through measurement and feedback control. In this work, we analyze a realistic active Szilard…
