Need help with temperature dependent model
I am a fourth-year student at New Zealand University. My name is Xu Ke. I have a project to generate a temperature dependent model for inductor, capacitor and diode by using PLECS. PLECS is software which acts as a toolbox for MATLAB. In my models, the temperature is very low, about negative 196 degree C … Continue reading Need help with temperature dependent model
In what form is water available in LN2?
Does anybody know in what form water is available in LN2? There probably is a block of ice in the bottom of the tank. But as water comes in many shapes, I can imagine snow or crystals floating free in the LN2. When water is available in LN2, could small particles of dirt act as … Continue reading In what form is water available in LN2?
Separating gases using cryogenics
We are looking for some consulting engineers who understand how to separate gases using cryogenics. We have a new process which takes biomass and converts it to 5 gases and we need to separate these gases into their pure forms. Thanks for your help.

Any experience with Tungsten or Tantalum metal springs in a low temp environment?
I would like to use metal springs made of Tungsten or Tantalum in low temperature environment. Does anybody have any experience with such springs? More precisely, I would like to make compression springs by rolling tungsten or tantalum wire on a rod. I expect that, typically, the spring constant will increase by let say 30%. … Continue reading Any experience with Tungsten or Tantalum metal springs in a low temp environment?
Standards & specifications for pipe & tube couplings
I am interested in finding out more about cryogenic applications and what standards, specifications and test methods (ASTM, etc.) are required for qualification of pipe and tube couplings.
Request for Assistance: Cryogenic MEMS Pressure Sensor
I am working on a National Science Foundation grant with researchers from Silicon Valley to develop a new type of MEMS pressure sensor. Given my background in cryogenics I was wondering if it could be adapted to that environment and am exploring research opportunities. Initial thoughts are to develop a submersible differential pressure sensor. Specific … Continue reading Request for Assistance: Cryogenic MEMS Pressure Sensor
Looking for a test house to test the static coefficient of friction under cryogenic conditions
I am looking to find a test house that is capable of testing the static coefficient of friction under cryogenic conditions. We can be flexible on most of the test parameters, including the test coupon configuration, but we're looking for a test house that can provide the following test environment: • Vacuum = 0.1 torr … Continue reading Looking for a test house to test the static coefficient of friction under cryogenic conditions
