New Track Etched Separation Data and Model
I’ve been working hard on my model paper for a few months now. My first attempt at doing separations with Track Etched (TE) membranes, which are all 6um thick and come in pore sizes of either 30 nm or 50 nm, resulted in data that was all over the place: Note that the gold concentrations are…
Dielectrophoresis Induced by a Nanoporous Membrane
ByJirachaiIt is expecting that the high electric field gradient at the nanopore entrance could amplify the dielectrophoretic force so that the nanoparticles transported toward the membrane could be manipulated based on their polarizabilities. To prove the concept, the electric field was applied across the nanoporous membrane while a bolus of gold nanoparticles was delivered across…
Effect of bias on amorph film structure
Thanks to SiMPore’s push for TEM grids, we’ve produced a lot of amorphous material in the last month under different deposition conditions. Below I’ve illustrated the different film structures resulting from depositing with and without substrate bias and heating. Without bias, the amorphous film exhibits clusters of thicker/denser? material (darker spots). Intuitively, this makes sense…
Simple Sieving Model
ByJimIn an effort to better understand and check Karl’s model of sieving, I’ve built a significantly simpler version. The goal is to investigate the potential benefits of thinner membranes in dead-end filtration and separations. In my model 1 ml of water is displaced from the top bucket to an originally empty bottom bucket with a…
Articles for (Jun/06/2014)
ByHenryHi all, i have to present for a biomechanics journal club meet next Friday (Jun/06/2014) and figured that i might as well double-dip the presentation. Currently i am leaning forward to present this article: Takano (Futai) microfld nanofld 2012 [pocket-sized cell culture] which showcased a pocket-sized, stand-alone device for cell culture. No need for…
