Fisher Team Update Nov ’14
ByFernandoHi All, just a quick post to up date you on what we are up to. 3 Things going on in the lab: Ryan continues to make his nano particles using chips, he is loading them with an anti-inflammatory agent (parthenolide) and testing them on macrophages in vitro. Hopefully more on that soon. Niecy just…
Carbonized membranes stable in KOH
I did a small experiment to demonstrate that a carbonized membrane would be stable in a harsh alkaline solution, such as KOH. I soaked a carbonized membrane and untreated membrane in %5 KOH at 40 C for an hour in an oven. As you can see, the carbonized membrane is still in-tact and the untreated…
EO as a function of pore radius
ByJimFrom Jess’ manuscript … From Wikipedia … From Tom’s ACS nano paper … The Dagan equation (2) for flow through short pores used to predict flow through pnc-Si is given by: where r is the average pore radius, DP is the pressure drop across the membrane, l is the membrane thickness and m is the…
ADSC Differentiation Due to Porous Membranes Day 1 Results
ByAndreaOverview: After trying an initial experiment of growing ADSCs on TCP and 3um translucent (TE) membranes and then placing them onto TCP or 3lp SiO2 membranes, it was determined that further studies should be conducted. For this experiment we grew ADSC on TCP, 3um translucent (TE) membranes, and 0.4um transparent (TE) membranes. Once the cells…
SEM x-section of 30-50-30 NSN showing increased thickness after RTP
This is a continuation of earlier work showing 30-100-30 NSN x-sections where the Si layer thickness increases from ~92 nm before RTP to ~130 nm after RTP. Below are SEMs showing a ~50 nm thick a-Si film becoming a ~62 nm thick pnc-Si. (1000 C, 50 C/s, 60 s in susceptor, RTP after EDP etch) I…
Fibroblast Growth Take 3
A third fibroblast (L1 3T3, P22) growth test was conducted using glass, untreated and tissue culture treated plastic, and RTPed pnc-Si (W509) as substrates. Cells were grown in DMEM +10% FBS changed every 48 hours. R values are for the fit N=No*exp^(r*t), where r has units of divisions/hour. For this trial fibroblasts grown on glass,…
