MEMs and membranes: a Liver Assist Device

I recently popped out membranes from wafers 1064 and 1065 for our lab. I only started with about half a wafer, but these are the numbers from the extraction: Wafer ID # of In-Tact Extracted Membranes : High/Low Porosity # I broke during extraction # already broken before extraction # apparently under etched 1065 (100W)…

Here is the analysis of the wafers used in the pressurized gold separations: SC 199   Stat Result Mean Equiv Diameter 17.84 nm Median Diameter 18.30 nm Porosity 2.2% Weighted Mean Diameter 20.81 nm 90% Diameter 26.64 nm Roundness .782 Separates 10 nm from 15 nm w225   Stat Result Mean Equiv Diameter 18.33 nm…

Using the techniques described in my previous post: TEM Tomography of NPN and npMgF2, we have recreated some tomograms that have contour (position) and height (depth) information contained in them. Our goal now is to express that height information in the form of a surface, or volume.         Segmentation Having some evidence that…

Here are the Vascular Interviews in comma separated value form if you want to download them. Here is what I learned or had reinforced. An arteriovenous fistula (AVF) is the preferred method for creating an easily cannulated access point to large volumetric blood flow for hemodialysis. Normally the distal end of an artery in the arm (e.g. brachial or…
