Yeah, I understand I need to amplify it and increase the frequency of the input signal. Looking into it I'm thinking one of the things confusing me is I saw a mosfet / transistor symbol in the circuit and it seems to correspond to a vacuum tube. Which I'm just realizing is the analog equivalent...
How is this done. Been reading about sputtering and DC sputtering is extremely simple. However, I'm not very experienced with RF circuitry so understanding exactly how to design that circuit confuses me a bit. Been reading about RF circuits but to generate an RF signal every method I find uses...
I'm aware that you "dope" them with phosphorous for n-type and boron for p-type (I'm aware other materials can be used and other dopants are preferred in other situations). My question is exactly how is this done? Temperature, Pressure, Sputtering, etc.A white paper or something of the exact...
It's pretty easy if you know the structure. If you don't then some sort of mass spec is your only hope on a real sample.
You basically need to find a repeating unit of structure then calculate the weight / volume of that repeating unit. On planar surfaces sometimes planar density is...
cavitation is bubbles of compressible gas inside of a fluid.
flash evaporation is the single stage fluid->gas transiation.
These aren't 100% related. You mention CFD. Are you trying to make a model for heating fluid to the point it evaporates then computing how the caviation (bubbles...
Vector math does this for you. Thing is if you look at the charge of the center of the wire it won't make much sense. That's because the magnetic field is circular around the wire so there is no direction of the magnetic field if you think from the center of the wire. Look at the surface instead...
I'm curious what models there are for calculating the Electric Susceptibility in crystalline solids and any books that describe maxwell equations in solids well. I'm interested in how to predict index of refraction of materials and the texts are a bit above my head as I haven't really dealt with...
I've gotten really interested in CFD and DFT recently. I have a BS in Chemical Engineering and will be 25 in about a month. Been working in the oil industry for the last 2 years and before that I worked in a carbon nanotube and graphene 'factory' for lack of a better term that I can come up with...
Depends on what you want to do. If you want to do real research in a chemical related field you need a PHD nowadays to be competitive. Master's means a lot in other industries but not so much in chemical industries. Generally if you get a master's it's best to come back and get an MBA after you...
This isn't simple, a lower limit might be able to be calculated fairly easily. Essentially if he's giving you a specific heat / latent heat value he's probably wanting you to get the temperature of the tires below the self-ignition temperature of the tires which is ~400 C. Also tires have a high...
In engineering at least EVERY professor also had a side company based on their research (you typically can make deals with your university to work a company though they will want a piece of the action). So a salary of 80-100k was just what they made from the university. In oklahoma, we could...
Chemistry and chemical engineering give you the most options out of college hands down, imo. Also, research into materials has really been homogenized between disciplines. In depth, Quantum mechanical knowledge at phd level and materials research is pretty much a requirement. However, the...
(e^-x - 1) / (e^-x +1)
Multiply num and denom by e^x
(1 - e^x) / (1 + e^x)
so you if you got positive 1 with negative infinite that makes sense as that reduces to
1/1 = 1
Corn Starch or something similar. You want something that will be high resistant to penetration. It has the properties that when exposed to extreme force it hardens into a concrete like substance. As in you can run on top of it, but wouldn't be able to walk across it. Really cool that way.
oops realized my link was messed up. Here is again go to low gassing->rubber and elastomers
http://outgassing.nasa.gov/
Remember it isn't only about material, but also material prep. You WILL need to heat the material in a good vacuum to prepare it. It recommends Silicone Rubber. If you look...
