The premise of this project is built around the ideas that our membranes can: Be used as concentrators for very dilute targets Catch and hold particles for further processing on the membrane Here, we wish to test these ideas for dilute viral genome extraction in large volumes of waste water. We looked to improve upon…

I used the spectroscopic ellipsometer to measure several wafers deposited using the AJA system.  I verified film uniformity as well as film quality using index of refraction as the metric.  The term “w/ Bias” refers to an applied RF power over the substrate.  The bias adds energy to the surface as adatoms re-arrange during deposition…

Previously I had posted a chart depicting the permeabilities of SepCon membranes from w310. I went back and noticed some errors in the equations. Here is an updated version of that chart. Also included is a sample where I used the ultracentrifuge to clarify the protein right before the experiment, which should remove any larger…

I’ve been culturing RPE cells over here in Rochester for my MgF2 fabrication paper, in which the goal is to make a permeable Raman compatible cell substrate. My previous work had shown polarization of RPE cells (via-ZO-1 staining) on nanoporous MgF2 nanomembranes, but in the meantime, I have reworked my MgF2 substrates to be thicker…

Background Details: Josh Miller & I have made some recent progress in the NPN LO work.  We had several ø6″ wafers w/ 100 nm of thermal oxide processed by Rogue Valley, wherein they deposited 650 nm of poly-Si (LP-CDV) followed by 50 nm of low-stress SiN (LP-CVD).  Josh added the a-Si + SiO2 layers at…
