EPJ B – Round-up on the conductivity of carbon nanomaterials

An 8-unit-cell long (10, 0) CNT end-contacted with Au(111) metallic electrodes

A new Colloquium article by I. Deretzis and A. La Magna published in EPJB reviews the possibilities offered by all-carbon electronics as well as elucidating drawbacks in view of future applications.


EPJ B – New theory predicts dispersion in porous solids

EPJB –  New theory predicts dispersion in porous solids

Modeling the transport of fluids in porous solids is a problem of general interest for its implications in construction engineering, industrial catalysis, hydrology, agriculture and geology. The classical approach uses an equation derived from continuum mechanics which is problematic and often gives incorrect predictions. When the porous medium presents many scales of variability the problem becomes intractable.


EPJ B - Solids under pressure

EPJB - Solids under pressure

Constant-pressure molecular dynamics simulations allow the study of systems where external pressure is a driving force for a structural transformation.


EPJ B - Geometry matters

EPJ A – Validating Aspects of the Strong-Coupling Regime of QCD

A colloquium published in EPJ B provides a thorough formulation of the theory of the insulating state by means of geometrical concepts, which were somewhat hidden and implicit in the original literature.


EPJ B - Complexity Theory and the National Baseball Hall of Fame

Individual success in competitive endeavors, such as sports or academia, is the result of many factors, some of which are time-dependent. In order to compare human achievements from different time periods, we need to normalize success metrics so as to avoid a time-dependent bias in the comparison of the statistical measures. A novel 'detrending' approach presented in EPJ B removes precisely this bias and allows for an objective comparison across time.


EPJ B – Au and Cu as building blocks of high-density memory devices

Gold and copper atoms adsorbed on a NaCl surface behave as isolated atoms and complex electronic interactions with the surface are negligible. A study by a group of Brazilian researchers uses first-principles simulations to measure the electronic and magnetic properties of gold and copper atoms adsorbed on NaCl(001) surfaces, as well as the modifications in these properties upon charge injection.


EPJ B – A step up in the game of electron-ion dynamics simulations

EPJ B – A step up in the game of electron-ion dynamics simulations

A Colloquium paper by McEniry et al. published in EPJ B surveys the theory and applications of a new family of computational methods, namely Correlated Electron-Ion Dynamics, which enable the simultaneous evaluation of the electronic current, along with the current-induced forces and subsequent motion of the nuclei.

EPJ B – Longitudinal polarization analysis, SANS souci

Longitudinal polarization analysis, SANS souci

Ground breaking experiments in EPJ B by D. Honecker and colleagues on an FeCr two-phase nanocrystalline alloy demonstrate the power of one-dimensional neutron-spin analysis in a small-angle neutron scattering (SANS) experiment.


Geysers of Helium burst as if liquid

Geysers of Helium burst as if liquid

New experiments on the flow of solid He through a microscopic hole reveal a mechanism that triggers the geysers based on the breakdown of a plug located upstream of the source chamber.

The vacuum expansion of solid helium through a micrometric orifice was suggested as a mean to inject excess vacancies into the solid bulk [R. Grisenti et al, J. Electr. Spectr. 129 (2003) 201]. But while the He flow seems smooth, unexpected periodic bursts out of the orifice (geyser effect) are observed during these vacuum expansion experiments.
