Viscosity measurements of PEO solutions by AFM with long nanowires

Hosseini M., Yazdanapanah M.M., Siddique S., Cohn R.W., University of Louisville, US

We recently demonstrated that long metal nanoneedles grown on atomic force microscope (AFM) probes can give very clear measurements of the surface tension, evaporation rate and viscosity of simple liquids. However, in the case of [...]

Efficient 3-D Numerical Code “FastSlipStokes” for Drag Force Calculation Due to Slip Flow

Ding J., Ye W., Georgia Institute of Technology, US

Drag force calculation due to slip flows is important in predicting the performance of the microstructures with minimum feature size around 1 mm. In this paper, an efficient numerical approach to compute the drag force [...]
