The effect of turbulence, gravity, and non-continuum hydrodynamic interactions on the drop size distribution in clouds
Johnson Dhanasekaran, Donald. L. Koch
The evolution of micron-sized droplets in clouds is studied with focus on the 'size-gap' regime of 15-40 radius, where condensation and differential sedimentation are least ef…

Current rectification by nanoparticles in bipolar nanopores
Andrés Córdoba, Joan M. Montes de Oca, Johnson Dhanasekaran +2
Bipolar nanochannels comprising two domains of positively and negatively charged walls along the pore axis are known to rectify current when exposed to an electric potential bias.…

Ionic transport in electrostatic Janus Membranes. An explicit solvent molecular dynamic simulation
Joan M. Montes de Oca, Johnson Dhanasekaran, Andres Cordoba +2
Janus --or two-sided, charged membranes offer promise as ionic current rectifiers. In such systems, pores consisting of two regions of opposite charge can be used to generate a cur…
