On the prediction of the induced damage by the start-up sequence of Francis turbines: On operational resilience framework
Mario Paolone, Christophe Nicolet, Elena Vagnoni, Martin Seydoux
The number of transient operations in hydraulic machinery connected to power grid, notably start-ups and shut-downs, has observed a substantial increase in recent decades, primarily driven by the global shift toward intermittent renewable energy sources. S ...
2024Liquid film instability of an internally coated horizontal tube
François Gallaire, Edouard Boujo, Yves-Marie François Ducimetière, Shahab Eghbali
We study numerically and theoretically the gravity-driven flow of a viscous liquid film coating the inner side of a horizontal cylindrical tube and surrounding a shear-free dynamically inert gaseous core. The liquid-gas interface is prone to the Rayleigh-P ...
AMER PHYSICAL SOC2023Improved Cell-Free Transcription-Translation Reactions in Microfluidic Chemostats Augmented with Hydrogel Membranes for Continuous Small Molecule Dialysis
Sebastian Maerkl, Laura Sophie Grasemann, Barbora Lavickova
Increasing the protein production capacity of the PURE cell-free transcription-translation (TX-TL) system will be key to implementing complex synthetic biological circuits, and to establishing a fully self-regenerating system as a basis for the development ...
AMER CHEMICAL SOC2022Cryo-EM structures of a LptDE transporter in complex with Pro-macrobodies offer insight into lipopolysaccharide translocation
Henning Paul-Julius Stahlberg, Dongchun Ni, Iwan Zimmermann, Denis Bucher
Lipopolysaccharides are major constituents of the extracellular leaflet in the bacterial outer membrane and form an effective physical barrier for environmental threats and for antibiotics in Gram-negative bacteria. The last step of LPS insertion via the L ...
2022Numerical and experimental study of the dynamic thermal resistance of ventilated air-spaces behind passive and active façades
Dolaana Khovalyg, Mohammad Rahiminejad
The variation of the thermo-hydrodynamic behavior of the airflow in the ventilated cavity behind external claddings in a wall structure could potentially affect the overall thermal resistance of the entire structure. Although the impact of an enclosed air- ...
2022Time-Resolved Spectroscopy of Selective Catalytic Reduction (SCR) Catalysts under Transient Conditions
Understanding the mechanisms behind chemical transformations is key to developing improved catalytic systems. To this end, operando spectroscopy has contributed significantly to the advancement of our molecular view of many reactions at the heart of the ch ...
EPFL2021Investigating active phase loss from supported ruthenium catalysts during supercritical water gasification
Frédéric Vogel, Mohamed Tarik, David Baudouin
Active phase loss mechanisms from Ru/AC catalysts were studied in continuous supercritical water gasification (SCWG) for the first time by analysing the Ru content in process water with low limit-of-detection time-resolved ICP-MS. Ru loss was investigated ...

2021Estimating Mean Bedload Transport Rates and Their Uncertainty
Measuring bedload transport rates usually involves measuring the flux of sediment or collecting sediment during a certain interval of time Δt. Because bedload transport rates exhibit significant non‐Gaussian fluctuations, their time‐averaged rates depend a ...
