Pathways to enhance electrochemical CO2 reduction identified through direct pore-level modeling

Sophia Haussener, Shuo Liu, Etienne Boutin, Evan Fair Johnson

Electrochemical conversion of CO2 to fuels and valuable products is one pathway to reduce CO2 emissions. Electrolyzers using gas diffusion electrodes (GDEs) show much higher current densities than aqueous phase electrolyzers, yet models for multi-physical ...

Scaling behavior of bedload transport: what if Bagnold was right?

Christophe Ancey

There is a paradox in the relationship between bedload transport rates and flow variables: laboratory and field studies have reported on how bedload transport rates depend on flow variables through a power law, but none of the empirical laws fitted to the ...

Friction Induces Anisotropic Propulsion in Sliding Magnetic Microtriangles

Ignacio Pagonabarraga Mora

In viscous fluids, motile microentities such as bacteria or artificial swimmers often display different transport modes than macroscopic ones. A current challenge in the field aims at using friction asymmetry to steer the motion of microscopic particles. H ...

‘Ecological concerns weren’t the main reason why I took the bus, that association only came afterwards’: on shifts in meanings of everyday mobility

Livia Bianca Fritz, Franziska Meinherz

Reducing the modal share of car travel in commuting implies challenging meanings of everyday mobility that tie commuting to driving. Existing research has focussed on describing ways in which everyday mobility is meaningful. However, why shifts in meanings ...

Understanding multimodality through rhythm of life. An empirical evidence from the Swiss case study

Alexis Gumy, Guillaume Simon Joseph Drevon

The car dominance car in the urban transport system may contribute to health and environmental troubles. In recent years, multimodality appears as a central issue for public policies as they try to encourage and develop the modal shift in favour of walking ...

Toward Sustainable Ridesourcing Services: A Simulation Study on the Effects of Congestion, Fleet Size, and Willingness to Share

Nikolaos Geroliminis, Caio Vitor Beojone

Human mobility in large cities is a complex dynamical system with high density of population, many transport modes to compete for limited available space and many operators that try to efficiently manage different parts of this system. New emerging modes o ...

Dealing with Daily Rhythms: Families’ Strategies to Tackle Chronic Time Pressure

Vincent Kaufmann, Philippe Gerber, Guillaume Simon Joseph Drevon

As suggested by the conservation of resources theory, in contemporary societies time is considered as a limited resource in the same way as money and energy. In the current paper, a novel daily rhythm approach related to motility is presented, in order to ...

Empirical analysis of large-scale multimodal traffic with multi-sensor data

Nikolaos Geroliminis, Nan Zheng, Hui Fu

Recent advances in the network-level traffic flow modelling provide an efficient tool for analyzing traffic performance of large-scale networks. A relationship between density and flow at the network level is developed and widely studied, namely the macros ...

Lowering CO2 emissions in the Swiss transport sector

Philippe Thalmann, Marc Vielle

In Switzerland, transportation represents 41% of CO2 emissions from energy combustion (2016), a much higher share than in the European Union (EU) (28%) or even the USA (34%). While total Swiss CO2 emissions decreased by 10% between 1990 and 2016, CO2 emiss ...
