Crystal Growth inside Nanopores

Cindy Hartnett – professor of mechanical engineering at Louisville requested some pnc-Si chips after reading our PNAS paper. In requesting the material she mentioned … I’ve long been searching for a low-voltage way to drive some micro-actuators. Electrokinetic pumps looked good but until now the necessary voltage was far too high. About a month after…

Introduction The Membrane Flow Analysis Device for Gas (MFAD-G), Quality Control Model, is the first* of a 3-version series of devices that, altogether, will allow use-specified measurement of flow rate and flow pressure of gas and liquid media through chip-mounted membranes. The QC Model has a rudimentary form of the general system and acts as…

On Friday Josh and I assembled  Sepcon chips with calculated porosity of ~6.5 %, and avg. pore diameter of ~40 nm into Sepcons.   I was able to pass 40nm gold through the pores (we don’t have any gold larger than that).  Note the “Bad” retentate – for some reason one of the sepcons didn’t filter anything. On…

A new user in URnano has used the “old” susceptor for a ~270 C  (I might have the exact number wrong, but it is relatively low temp) to heat In on GaAs.  I don’t think there was ever a good reason for using the RTP for this process, but what is done is done.  I…

Just to give a brief background, I have been working with endothelial cells to make a microvessel mimetic device, and one of the important requirements for endothelial cell culture is to be able to grow the cells under physiological levels of shear stress. Further, since I am trying to achieve neutrophil transmigration through the endothelial…
