Burst Pressure, Permeance of NSN pnc-Si SEPCONS with large pores
Karl, Charles and I measured the burst pressure and permeance of some 30-50-30 and 30-100-30 NSN. Burst Pressure: The SEPCONs readily burst at pressures under 1 psi when the flow was directed from the backside of the chip through the membrane. The membranes were able to withstand higher pressures when the pressure was applied from…
Fluorescein transport: O-ring position and wafer variability
After diffusing through a polymeric or pnc-Si membrane in the transwell format, diffusing molecules meet an “unstirrred water layer = UWL” on the bottom of the membrane. The UWL acts as another resistance to transport into the receiver compartment. According to some PAMPA papers, the UWL can be greater than 1 mm in thickness without…

Permeance tests with new Omega rotameter
Yaron has acquired an Omega rotameter (FL-3803ST) with interchangeable flow tubes. The tubes operate in three different ranges low (6-61 mL/min, 042-15-N), medium (150-1,682 mL/min, 082-03-N), and High (1,000-23,752 mL/min, 034-39-N). I’ve attached an excel file with the calibration data plotted. We fit the curves with polynomial trendline to get equations. Also in the workbook…
Pore tunability with susceptor in RTP
A temperature series was performed last week over seven wafers annealed inside the susceptor (15 nm silicon). The objective was to determine if the current configuration of target materials would show pore tunability over the temperatures of interest (900 – 1100 C). Below is a series of TEM micrographs and their corresponding histograms. At the…
SEM FIB Lift-out of 50 nm NPN for TEM Analysis
ByKileanAs a step to identifying the particles that I am capturing in my systems, I am attempting to do an immunogold labeling with a CD 63 primary antibody and a 10 nm gold conjugated secondary. It is possible to run this analysis in an SEM, but the best confirmation method is using a TEM and…
