I reported last week that a 15 nm silicon film deposited with 05 W substrate bias yielded a highly porous film. This week, I wanted to confirm this effect as well as compare it to films deposited at 10 W and 25 W (our baseline). We find that the 05 W is reproducible and the…

A couple weeks ago, I presented a potential figure for my paper that didn’t make sense.  So, I did a couple more controls and put together this new figure.  This is the “diffusion through ‘non-porous’ SC348/cut-off of nonporous membranes” figure.  I redid it to include SC348 (the nonporous sample) and ‘typical’ pnc-Si as % of…

Hello Everyone, So i decided to do some calculations on our 2 different sets of experiments (Track Etched and NPN) and compare the applied and the required force of them, in addition to making sure that we are applying enough force on the particles to keep them captured. The experiment conditions for both TE and…

Today I made my first attempt at depositing aluminum oxide on pnc-Si using URInc’s Cambridge Nanotech’s Savannah 200 atomic layer deposition tool. Ritala and Leskela give a nice primer on ALD theory. ALD relies on layer-by-layer growth of film by reacting a precursor with the surface of interest. In this particular system, we react trimethylaluminum…

Okay, so after navigating this weird new method for posting, I have a semi interesting post today. I have been working on the experimental validation of my COMSOL predicted capture results and have finally completed the first round of those experiments (I say this after looking at the data). The experiments have been carried out…

Experiments were conducted to determine how effectively protein is bound by suspended graphene oxide (GO) particles. This is important for our application because we hope to use GO as a membrane to bind toxins present in blood. BSA (bovine serum albumin) was used as the test protein. Test samples consisted of a mixture of BSA…
