Current rectification and ionic selectivity of alpha-hemolysin: Coarse-Grained Molecular Dynamics simulations
Delphine Dessaux, Jérôme Mathé, Rosa Ramirez +1
In order to understand the physical processes of nanopore experiments at the molecular level, microscopic information from molecular dynamics is greatly needed. Coarse-grained mode…
Ionic transport through a protein nanopore: a Coarse-Grained Molecular Dynamics Study
Basdevant Nathalie, Dessaux Delphine, Ramirez Rosa
The MARTINI coarse-grained (CG) force field is used to test the ability of CG models to simulate ionic transport through protein nanopores. The ionic conductivity of CG ions in sol…
Temperature inversion in granular fluids under gravity
Rosa Ramirez, Rodrigo Soto
We study, via hydrodynamic equations, the granular temperature profile of a granular fluid under gravity and subjected to energy injection from a base. It is found that there exist…
p-Type semiconducting properties in lithium-doped MgO single crystals
M. M. Tardio, R. Ramirez, R. Gonzalez +1
The phenomenally large enhancement in conductivity observed when Li-doped MgO crystals are oxidized at elevated temperatures was investigated by dc and ac electrical measurements i…
Semiconducting Characteristics of Magnesium-Doped Al2O3 Single Crystals
M. Tardio, R. Ramirez, R. Gonzalez +2
DC and AC electrical measurements were performed to investigate the electrical conductivity of alpha-Al2O3:Mg samples with different concentrations of [Mg]^0 centers .The concentra…
