Adsorption Phenomena in Particle Transport Through a Fluid-filled Nanochannel
An important ingredient in future transport applications at the nanoscale will be the motion of suspensions of solid particles through channels. Calculations based on continuum dynamics and models are not reliable at this scale and [...]
Transport Properties For Carbon Nanotubes Under Hydrostatic Pressure
Multi-wall carbon nanotubes (MWNTs) were mixed with polystyrene (PS) by 20 wt%, which is close to the percolation threshold. Temperature (T) dependence of Seebeck coefficient (S) and resistance (R) for the sample (MWNT-PS) were measured [...]
On the Validity of the No-Slip Condition in Nanofluidics
Koumoutsakos P., Jaffe R.l., Werder T., Walther J.H., Swiss Federal Institute of Technology Zürich, CH
In a collaboration with experimental groups at NASA and ETH Zürich we conduct computational studies towards the development of biosensors in aqueous environments. Examples include arrays of carbon nanotubes that may operate as artificial stereocillia [...]
Water Ordering by Confinement in Carbon Nanotubes at 300K: Implications for possible design of proton-conducting nano-semiconductors
Molecular dynamics (MD) simulations suggest that water readily enters carbon nanotubes. This is also suggested by the fact that fluorescence in nanotubes is affected by the pH of external electrolyte. Distinctive symmetrical water structures emerge [...]
Study of Sample Dispersion Mechanisms in an Electroosmotically Pumped Microchannel
Debusschere B., Najm H., Matta A., Knio O., Ghanem R., Le Maitre O., Sandia National Laboratories, US
In many microfluidic separation processes, dispersion of sample peaks is a significant problem limiting the detection resolution. In this work, we use simulations to study the dominant dispersion mechanisms during a protein labeling process in [...]
Ion Channel Based Biosensors: Ionic transport in carbon nanotubes
Joseph S., Mashl R.J., Jacobsson E., Aluru N.R., Beckman Institute of Advanced Science and Technology, US
Transport of molecules through macromolecular pores is of considerable importance in many biological and nano-electromechanical systems. Ion channels found in cell membranes are crucial for shaping electrical signals and controlling flow of ions and fluids [...]
