Multiscale Poromechanics of Wet Cement Paste [PDF]

open access: yes, 2019
Capillary effects such as imbibition-drying cycles impact the mechanics of granular systems over time. A multiscale poromechanics framework was applied to cement paste, that is the most common building material, experiencing broad humidity variations ...

Low-energy, planar magnetic defects in BaFe2As2: nanotwins, twins, antiphase and domain boundaries [PDF]

open access: yes, 2013
In BaFe2As2, structural and magnetic planar defects begin to proliferate below the structural phase transition, affecting descriptions of magnetism and superconductivity.

Modeling friction: From nanoscale to mesoscale [PDF]

open access: yes, 2013
The physics of sliding friction is gaining impulse from nanoscale and mesoscale experiments, simulations, and theoretical modeling. This Colloquium reviews some recent developments in modeling and in atomistic simulation of friction, covering open-ended ...

Direct imaging of long-range ferromagnetic and antiferromagnetic order in a dipolar metamaterial [PDF]

open access: yes, 2020
Magnetic metamaterials such as artificial spin ice offer a route to tailor magnetic properties. Such materials can be fabricated by lithographically defining arrays of nanoscale magnetic islands.

Robust coupling of superconducting order parameter in a mesoscale NbN-Fe-NbN epitaxial structure [PDF]

open access: yes, 2009
We report an unconventional and promising route to self-assemble distributed superconductor-ferromagnet-superconductor (S-F-S) Josephson Junctions on single crystal [100] MgO. These structures consist of [110] epitaxial nano-plaquettes of Fe covered with

The challenges of nanostructures for theory [PDF]

open access: yes, 2003
It is tempting to believe that modelling in nanotechnology is much the same as that for conventional solid-state physics. However, important areas of nanotechnology address different systems.

Evolution of Complexity in Out-of-Equilibrium Systems by Time-Resolved or Space-Resolved Synchrotron Radiation Techniques

open access: yes, 2019
Out-of-equilibrium phenomena are attracting high interest in physics, materials science, chemistry and life sciences. In this state, the study of structural fluctuations at different length scales in time and space are necessary to achieve significant ...

Direct measurement of antiferromagnetic domain fluctuations

open access: yes, 2007
Measurements of magnetic noise emanating from ferromagnets due to domain motion were first carried out nearly 100 years ago and have underpinned much science and technology. Antiferromagnets, which carry no net external magnetic dipole moment, yet have a

Coulomb Interactions and Nanoscale Electronic Inhomogeneities in Manganites [PDF]

open access: yes, 2006
We address the issue of endemic electronic inhomogeneities in manganites using extensive simulations on a new model with Coulomb interactions amongst two electronic fluids, one localized (polaronic), the other extended (band-like), and dopant ions.
