Relation between a heterogeneous percolation model for cylinders and phase separation in the lattice fluid problem

A relationship based upon analogy is explored between (i) a lattice-based model for percolation by cylinders that employs distinct site types with unequal occupation probabilities in order to capture heterogeneities in the particle dispersion, and (ii) the ...

Intruders size-segregating under oscillating shear flows.

Christophe Ancey, Tomás Alfredo Trewhela Palacios

Granular geophysical flows are composed by particles of different sizes that segregate under the action of gravity and shear-induced dilatancy. Size segregation is the physical process by which small particle percolate through gaps left by the relative mov ...

Single-layer graphene membranes by crack-free transfer for gas mixture separation

Andreas Züttel, Duncan Thomas Lindsay Alexander, Emad Oveisi, Kumar Varoon Agrawal, Wen Luo, Mostapha Dakhchoune, Shiqi Huang, Guangwei He, Jing Zhao

The single-layer graphene film, when incorporated with molecular-sized pores, is predicted to be the ultimate membrane. However, the major bottlenecks have been the crack-free transfer of large-area graphene on a porous support, and the incorporation of mo ...

Variable stiffness strip with strain sensing for wearable robotics

Dario Floreano, Stefano Mintchev, Vivek Ramachandran, Jun Shintake, Carine Rognon, Alice Tonazzini

Variable stiffness technologies help to solve the conflicting requirements of strength, comfort, and safety in soft exoskeletons. Here, we propose a modular variable stiffness strip based on layer jamming as a mechanical solution to constrain users' degree ...

Analysis of crystalline phases and integration modelling of charge quenching yields in hybrid lead halide perovskite solar cell materials

Ulf Anders Hagfeldt

Organic inorganic metal halide perovskites (OIHPs) has emerged as promising photovoltaic materials the latest years. Many OIHPs, however, have complex material compositions with mixed cation and halide compositions, phase mixtures, as well as beneficial re ...

Study of synergetic effect, catalytic poisoning and regeneration using dielectric barrier discharge and photocatalysis in a continuous reactor: Abatement of pollutants in air mixture system

Sami Rtimi

In the present work the abatement of butyraldehyde (BUTY), dimethyl disulfide (DMDS) and their mixtures in gas phase was studied in continuous reactor at three different configurations: photocatalysis (TiO2 + UV), dielectric barrier discharge (DBD) plasma ...

Extremal attractors of Liouville copulas

Liouville copulas introduced in McNeil and Ne lehova (2010) are asymmetric generalizations of the ubiquitous Archimedean copula class. They are the dependence structures of scale mixtures of Dirichlet distributions, also called Liouville distributions. In ...

EFFECT OF THE BED LOAD GRADATION ON THE MORPHODYNAMICS OF DISCORDANT CONFLUENCES

Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca, Sebastián Guillén Ludeña, António Heleno Cardoso

Within the fluvial network, river confluences are particular areas characterized by complex hydrodynamic, morphodynamic and sedimentary processes. These processes have been observed to be governed by parameters such as the discharge ratio, the junction ang ...

From Nano- to Micrometer Scale: The Role of Antisolvent Treatment on High Performance Perovskite Solar Cells

Mohammad Khaja Nazeeruddin, Yi Zhang, Francesco Stellacci, Pascal Alexander Schouwink, Peng Gao, Sanghyun Paek, Giulia Grancini, Kyung Taek Cho, Evangelia-Nefeli Athanasopoulou

To date, antisolvent treatment has become one of the most important means to fabricate high efficiency perovskite solar cells (PSCs); however, the few reported antisolvents have not been analyzed on a uniform platform, and there is hitherto no clear reason ...

Energy- and momentum-conserving model of splash entrainment in sand and snow saltation

Michael Lehning, Francesco Comola

Despite being the main sediment entrainment mechanism in aeolian transport, granular splash is still poorly understood. We provide a deeper insight into the dynamics of sand and snow ejection with a stochastic model derived from the energy and momentum con ...
