Can someone help explain this e-mail?
Hey Jim –
Just got a call from the locksmith who had a report from security that someone in your lab is tampering with the lock on your lab door…by doing what they’re doing, they are able to get into your lab without a key (or swiping). It’s been fixed again, but we’re just making you aware that its happening.
Best,
Gayle
In a continuing study on how a post-silicon deposition Ar sputter affects morphology, I annealed three 15-nm films for 10 s, 60 s, and 300 s. If you recall in my first report, I found that the Ar sputter increases the porosity slightly for a 1000 C RTP and dramatically for a 900 C RTP….
One question we recently had was what does it look like when we perform a separation experiment when a membrane has a pinhole. I selected two membranes off 621 that appeared to have pinholes on both slits. I applied 1:2 standards to the top and allowed to diffuse for 24 hours. I collected the retentate…
The title really says it all. I have been attempting to make a better cell culture substrate with the Magnesium Fluoride Films. Previous posts have shown the overall structure of the film, and now I am trying to quantify the strength with a burst pressure measurement. In order to make a direct comparison, I needed to…
In order to verify the validity of the result of the five-layer structure I did last time, I deposited another wafer with NOSON stack, which has the identical thickness as that of the last time. The annealing condition is also same as the last time, which is 1 minute holding time at 1000C with a…
I’m currently trying to compare separations between different complex protein mixture. This was my first crack at depleted human serum. This mixture has been processed so that the most common blood proteins (such as albumin and immunoglobulins) have been removed. All three trials were performed using membranes from w338 in diffusion mode. 338 has a…
Below are a series of TEM micrographs showing a set of membranes produced last week. We RTPed these wafers at 700 (SC 062), 800 (SC 064) and 850 C (SC065) without the susceptor at a ramp rate of 100 C/s. The trend is increased pore size and porosity with increasing temperature which follows our intuition…
