Hi guys,
I'm a graduate student and currently doing some research on a packed bed - I want to collect gas data from the headspace of my samples so i thought of building a gas collecting chamber on top of the vessel, where i can take gas measurements using calorimetric gas tubes. I'm not sure...
Hello Guys,
So I'm trying to build a database of organic compounds that are of interest to the pharmaceutical industry. Most importantly compounds containing heteroatoms (>= 15% by mass). Where do i start!? any good websites or books, with a useful appendix you can tell me about?

Hey,
i've been trying to find a better fit for a correlation, the numbers I'm dealing with are really small and when i try to solve for the coefficients using the inverse function on the matrices in Matlab i get this error:
Warning: Matrix is close to singular or badly scaled. Results

well I'm trying to measure the concentration of ammonia so when it adsorbs on the surface of the sensors it causes the frequency changes Δf because of Δm applied. i got this idea from the heidelberg PH pill that gives out the measurements by radio transmission, and i was hoping that there's a...
Hello, I'm not an electrical engineering student so please bare with me...
anyways if let's say you swallow a pill containing a piezoelectric sensor to measure adsorption of a molecule in the stomach how can you detect the changes in frequency? if there is no "physical" electrical connections...
