Achieving visible light-driven hydrogen evolution at positive bias with a hybrid copper-iron oxide|TiO2-cobaloxime photocathode

Kevin Sivula, Florent Alexandre Boudoire

H-2 is an environmentally-friendly fuel that would allow for a circular economy but its sustainable production, e.g. from solar energy and water, remains a challenge. A hybrid CuFexOy|TiO2-CoHEC (CoHEC = chloro([4,4 '-bipyridine]-2,6-dicarboxylic acid)bis( ...

Turbulent patterns in wall-bounded shear flows: invariant solutions and their bifurcations

Florian Reetz

When laminar shear flows in large wall-bounded domains transition to turbulence, the flow exhibits spatio-temporally chaotic dynamics. Despite its chaotic dynamics, the flow may self-organize into characteristic spatially periodic patterns of unknown origi ...

Katabatic winds diminish precipitation contribution to the Antarctic ice mass balance

Alexis Berne, Jacopo Grazioli

Snowfall in Antarctica is a key term of the ice sheet mass budget that influences the sea level at global scale. Over the continental margins, persistent katabatic winds blow all year long and supply the lower troposphere with unsaturated air. We show that ...

Spatio-temporal patterns in inclined layer convection

Tobias Schneider

This paper reports on a theoretical analysis of the rich variety of spatio-temporal patterns observed recently in inclined layer convection at medium Prandtl number when varying the inclination angle gamma and the Rayleigh number R. The present numerical i ...

How street canyon configuration control the accessibility of solar energy potential: Implication for urban design

Jean-Louis Scartezzini, Jérôme Henri Kämpf, Dan Assouline, Nahid Mohajeri Pour Rayeni, Govinda Upadhyay

While the effects of street-canyon configuration on temperature, wind speed and direction, and air quality have received much attention, its impact on solar energy potential has not been much studied. This paper focuses on two aspects of the street-canyon ...

Rayleigh-Taylor instability under an inclined plane

François Gallaire, Gioele Mariano Nicolò Balestra, Pierre-Thomas Paul Brun, Pierre Rieu

We revisit the canonical Rayleigh-Taylor instability and investigate the case of a thin film of fluid upon the underside of an inclined plane. The presence of a natural flow along the plane competes with the conventional droplet forming instability. In par ...

Silicon Supported Membranes for Improved Large-Area and High-Density Micro/Nanostencil Lithography

Jürgen Brugger, Marc Antonius Friedrich van den Boogaart

In this paper, the fabrication and use of stencils for full-wafer scale shadow mask (stencil) lithography is described. The stencils fabricated via microelectromechanical systems are mechanically stabilized and show clearly reduced stress-induced membrane ...
