Cu2O Nanowire Photocathodes for Efficient and Durable Solar Water Splitting

Michael Graetzel, Jingshan Luo, Matthew Thomas Mayer, Marcel Roland Schreier, Ludmilla Steier, Minkyu Son

Due to its abundance, scalability, and nontoxicity, Cu2O has attracted extensive attention toward solar energy conversion, and it is the best performing metal oxide material. Until now, the high efficiency devices are all planar in structure, and their pho ...

Non-diffusive transport of suprathermal ions by intermittent turbulent structures

Ambrogio Fasoli, Ivo Furno, Paolo Ricci, Kyle Gustafson, Alexandre Dominique Bovet

We report on recent experimental, numerical and theoretical investigations of suprathermal ion transport and turbulent plasma dynamics in TORPEX. TORPEX is a toroidal device in which field-aligned blobs are intermittently generated and propagate across a c ...

Preparation, kinetics, mechanism and properties of semi-transparent photocatalytic stable films active in dye degradation

César Pulgarin, Juan Kiwi, Christophe Roussel, Laura Victoria Suárez Murillo

The photocatalytic activity, mechanism and characterization of polyethylene-TiO2 films (PE-TiO2) during the discoloration/degradation of methylene blue (MB) are reported in this study. PE-TiO2 films were prepared at moderate temperatures (similar to 90 deg ...

MATHICSE Technical Report : Multiscale methods and model order reduction for flow problems in three-scale porous media

Assyr Abdulle, Ondrej Budác

A new multiscale method combined with model order reduction is proposed for flow problems in three-scale porous media. We derive an effective three-scale model that couples a macroscopic Darcy equation, a mesoscopic Stokes-Brinkman equation, and a microsco ...

Enhanced permeation arising from dual transport pathways in hybrid polymer-MOF membranes

Wendy Lee Queen, Daniel Teav Sun

The rise of anthropogenic global warming has sparked new interest in developing strategies to mitigate carbon dioxide emissions. Conventional carbon capture processes are not economically viable at scale due to their enormous energy cost. Membrane-based se ...

Rates of microbial hydrogen oxidation and sulfate reduction in Opalinus Clay rock

Rizlan Bernier-Latmani, Alexandre Bagnoud

Hydrogen gas (H2) may be produced by the anoxic corrosion of steel components in underground structures, such as geological repositories for radioactive waste. In such environments, hydrogen was shown to serve as an electron donor for autotrophic bacteria. ...

In-Situ Monitoring of Moisture Ingress in PV Modules Using Digital Humidity Sensors

Christophe Ballif, Hengyu Li, Laure-Emmanuelle Perret Aebi, Fanny Sculati-Meillaud, Eleonora Annigoni, Marko Jankovec, Federico Paolo Galliano

A new in-situ moisture monitoring technique for photovoltaic (PV) modules is proposed using miniature digital humidity and temperature sensors. The sensors were embedded in three different ethylene-vinyl-acetate (EVA) stacks and proved to be resistant to l ...

MATHICSE Technical Report : An optimization-based numerical method for diffusion problems with sign-changing coefficients

Assyr Abdulle, Martin Ernst Huber, Simon Clément Damien Lemaire

A new optimization-based numerical method is proposed for the solution of diffusion problems with sign-changing conductivity coefficients. In contrast to existing approaches, our method does not rely on the discretization of a stabilized equation and the c ...

An octree-based adaptive semi-Lagrangian VOF approach for simulating the displacement of free surfaces

Marco Picasso, Gilles Steiner, Viljami Henrikki Laurmaa

A numerical method based on an adaptive octree space discretization for the simulation of displacement of free surfaces is proposed and applied to 3D free surface flow problems. A VOF approach is combined with a mass-conserving semi-Lagrangian time-steppin ...
