Molar flow thought pores with different diameters under 1 psi.
First, I calculated molar flow based on porosity histograms extracted from TEM images. And then compared it with the actual experimental data. Here are few examples of this.
Hi all, During last NRG meeting some questions are raised on what is the transmembrane pressure in Dean’s chip-in-a-beaker dialysis system and what is the direction of flow of the whole system. i gave them some thought and proposed the following scenario. Please feel free to correct me should I made any mistake. i am simply throwing…
Presentation in this post is based on the paper entitled “Large Area Synthesis of a Nanoporous Two-Dimensional Polymer at the Air/Water Interface”. Paper: Murray(King)JACS15 Supporting Information: Murray(King)JACS15 – SI Presentation Slides (PDF): Two-Dimensional Porous Membranes
I have been exploring the efficacy of different methods for removing the native oxide from the surface of the sacrificial silicon layer prior to liftoff etch with XeF2. As a reminder, with liftoff of SiN membranes, one can simply dip the sample in BOE solution for a few seconds to strip the native oxide. This…
I have been trying to verify that my MgF2 material is cytocompatible (e.g. no different than tissue culture plastic), and attempted Live/Dead staining to confirm. The following images are from P6 HUVECs with Invitrogen L3224 Live/Dead stain on MgF2, NPN, and tissue culture plastic after ~96 hours. The devices were initially seeded at 5e5 cells/mL,…
The Gaborski lab has been working with Blanca’s lab performing some scoping tests w/ SiN and SiOx microporous membranes. The aim is obtain proof of concept results regarding the efficacy of using a microporous membrane to trap sub-micron particles with DEP. Last week, we tested w/ our 200 nm polycarbonate beads. We were able to…
In my previous posts so far, I performed simulations to understand the behavior of TEER variation upon changes in electrode and membrane configuration. None of those models addresses the effects of cell growth on the TEER values. In real experiments, people measure the TEER of system before adding the cells (background TEER), and then monitor…
