Scaling of conductivity and Young’s modulus in replicated microcellular materials

Andreas Mortensen, Andreas Rossoll, Yves Conde

Scaling exponents for the conductivity and stiffness of replicated microcellular materials exceed commonly predicted values of 1 and 2. We show here that this is caused by the fact that, in replicated microcellular materials, the solid architecture varies ...

Communication: Growing room temperature ice with graphene

Juan José Segura Sugranes

Water becomes ordered in the form of hexagonal ice at room temperature under controlled humidity conditions upon confinement in the nanometer range between protective graphene sheets and crystalline (111) surfaces with hexagonal symmetry of the alkali eart ...

Nondispersive solutions to the $L^2$-critical half-wave equation

Joachim Krieger

We consider the focusing

L^2

-critical half-wave equation in one space dimension

i \partial_t u = D u - |u|^2 u,

where

D

denotes the first-order fractional derivative. Standard arguments show that there is a critical threshold

M_* > 0

such that all ...

Conductive Gold Nanoparticle Mirrors at Liquid/Liquid Interfaces

Hubert Girault, Frédéric Gumy, Fernando Cortes Salazar, Micheal Diarmaid Scanlon, Dmitry Momotenko, Véronique Amstutz, Haiqiang Deng, Carlos Manuel De Melo Pereira, Pingping Fang

Gold nanoparticle (Au NP) mirrors, that exhibit both high reflectance and electrical conductance, were self-assembled at a [heptane + 1,2-dichloroethane]/water liquid/liquid interface. The highest reflectance, as observed experimentally and confirmed by fi ...

Huge critical current density and tailored superconducting anisotropy in SmFeAsO0.8F0.15 by low-density columnar-defect incorporation

Janusz Andrzej Karpinski, Sergiy Katrych, Yihan Jia

Iron-based superconductors could be useful for electricity distribution and superconducting magnet applications because of their relatively high critical current densities and upper critical fields. SmFeAsO0.8F0.15 is of particular interest as it has the h ...

Topology of evolving pore networks

Emmanuel Gallucci, Marco Stampanoni

Morphological and topological quantification of complex pore networks is of great relevance for environmental engineering, earth science and industry. Recent developments of 3D imaging techniques such as X-ray microtomography or X-ray microscopy provide an ...

Tunneling and percolation transport regimes in segregated composites

Peter Ryser, Claudio Grimaldi, Biagio Nigro

We consider the problem of electron transport in segregated conductor-insulator composites in which the conducting particles are connected to all others via tunneling conductances, thus forming a global tunneling-connected resistor network. Segregation is ...

Tunneling conductivity in composites of attractive colloids

Peter Ryser, Claudio Grimaldi, Biagio Nigro

In conductor-insulator nanocomposites in which conducting fillers are dispersed in an insulating matrix, the electrical connectedness is established by inter-particle tunneling or hopping processes. These systems are intrinsically non-percolative and a coh ...

Charge transport gap in graphene antidot lattices

Klaus Kern, Marko Burghard, Eva Carmen Peters

Graphene antidot lattices (GALs) offer an attractive approach to band-gap engineering in graphene. Theoretical studies indicate that the size of the opened gap is sensitive to the shape, size, and architecture of the nanoholes introduced into the graphene ...

Revisiting the Limit Behaviour of ``El Botellon"

Jean-Yves Le Boudec

Emergent phenomena occur due to the pattern of non-linear and distributed local interactions between the elements of a system over time. An example of such phenomena is the spontaneous self-organisation of drinking parties in the squares of cities in Spain ...
