Discoloration presentation

This is probably not of general interest, but for the sake of full disclosure, I have spent considerable time working with our wafer supplier (Virginia Seiconductor) to resolve some issues regarding the surface quality of their wafers. It would have been much more productive to simply switch suppliers, but unfortunately, they are the only place…

Jirchai summarized his data in this table … A question raised by a reviewer of our PNAS submission – and one that we’ve had for a long time – is what is the efficiency of the pump. The electrical power provided is calculated in the table for each configuration. As Chris mentioned in group meeting,…

A simple hydraulic permeability study was performed to determine whether carbonization would negatively impact water transport through the membranes. 5 slit square SepCons from SC 471 were carbonized and put in the ultra-centrifuge with a 500 uL starting volume.  The samples were spun for 10 minutes at 3000 RPM (equiv to 4.95 PSI starting). SC…

This paper (Variance of Streaming Potential) examines the sources of error in zetapotential measurements. Jess and Zydney both cite it in their EO papers as a source of experimental procedure – in particular this paper found that waiting for the pressure to equilibrate at discrete timepoints works better than a continuous ramp-up in pressure. From…

Hi all, recently we improved cell tracking with the use of SiR-DNA label (see highlights below).   random migration:  A. Representative cell tracking from three independent migration experiments, color-coded by the color bars to the left in red, green, and blue. B. Distributions of motility parameters (persistence time, instantaneous speed, average speed, pathlength, and displacement)…
