Wet Etching of Optical Thin Films   As a result of Christian’s trip and Kevin’s discussions with me, I have been wondering if we could make nanoporous MgF2 membranes for Raman spectroscopy. Part of the appeal in using our Si-based…

Scope: ADSCs were cultured on the bottom of the Corning 0.4um translucent membranes in DMEM+ 10% FBS+ 1% Pen-Strep. After 6 hours, the membranes were flipped over and placed into a 24 well plate. Of the four membranes with ADSCs…

I updated the software for the SSI.  The software seems to be working properly.  There are some differences, most of which I haven’t fully explored.  Notably, we can open and view log files easily with 3.8. It seems that we…

We have considered SiN membranes in PDMS channels as EOF pumps and as constrictions for insulator-based dielectrophoresis (iDEP). For EOF, thicker membranes may yield greater flow rates. For iDEP, a smaller membrane porosity, meaning fewer, smaller holes on a given…

This is in continuation to the studies that I published here. I used two types of membrane surfaces: nano nitride trenches (the back side of membranes) with pure nitride on the surface, and zero-second-etch nano nitride with a completely intact…

Hopefully many more details to follow, but JP, Josh M. and I doped some Si substrates with boron using a spin-on-glass.  It seems well known that heavily boron doped Si is more resistant to EDP etch than intrinsic or n-type…

Back when I first joined the lab I did some experiments where I varied the pressure driving a gold filtration experiment. The critical plot was this:   It seems unlikely that the sieving coefficient could change so dramatically with applied…

Sealing Patch Clamp Chips Canadian Patch Clamp Chip   I have been thinking about Handy Geldbard’s group and what would enable them to study groups of synapses. Currently, I am in discussion with Jennetta Hammond and Pat Lu trying to…

I have been working with JP over the past month to attempt to form a thin, continuous film of PdAg on a pnc-Si membrane using e-beam evaporation.    The aim of this is to test these for selective hydrogen permeability at…

The group in the attached paper have found a way to form pnc-Si using PECVD.   They use a 300-15-300 nm OSO stack with a 850 C (50 C/s, 30 s) RTP to form ~13 nm pores.  SiMPore attempted this in the…
