Contact Angles
We’ve built a set up for this but it’s not incredibly user friendly right now. It consists of a camera and a stage. Using the macro function of the camera you can take a close up image of the chip, but you must make sure the horizon line is straight i.e. camera and stage are…
SEM images of vertically cut track-etched membranes
TE membranes were first embedded in plastic material and then these samples were cut with microtome and imaged. The images below are of the 30nm and 80nm pore diameter membranes. 30nm ones came out better. It looks like the diameter isn’t really 30nm, look at the second picture. The dark spots are either tears or…
COMSOL model of SiMPore Liftoff device
I drew an approximation of the SiMPore liftoff device and ran the COMSOL model with 1 mL/min urea fluid flow in the upper channels and 2 mL/min dialysate in the bottom channels. With this initial model, the urea was cleared to 40% (60% removed). This is an instantaneous urea clearance rate of K= 0.6 mL/min….
Temperature series w/ 20 nm & 40 nm oxide
Last week, a RTP temperature series was performed on 15 nm Si membranes with 20 nm and 40 nm oxide layers. The purpose of this study was to 1. evaluate the effect of a thicker oxide on pinhole density and 2. identify a dependence of morphology on oxide thickness. Below are two graphs summarizing the…
PDMS array on nitrocellulose
Below is an image of the PDMS array on the nitrocellulose membrane. I’m trying to create a stamp that can be applied to the NC membrane, before PDMS is poured on. The idea is that the stamp will be heavy enough to keep the PDMS from soaking into the areas of the NC that the…
