I have three experiments in mind right now that I have occasionally tried to find out what happened and/or how they worked.<br /><ul><br /> <li> The (I think) heat pipe experiment where they tested what was described as a pump with no moving parts for ammonia, I think. If I recall correctly it was dirven by a temperature gradient and I have always wanted to see a diagram and explaination for that.<br /><br /> <li> The experiment where they grew the giant gallium arsenide crystal. The gallium arsenide started out in the top of the enclosure and they heated it up to evaporate atoms which condensed onto the seed. If the lattice developed a defect then they reversed the process by heating the crystal instead. What did they do with that crystal?<br /><br /> <li> Probably my all time favorite was the one where they used robotic syringes to deposit liquid into a chamber and then manipulated the drops with sound waves. They could spin the droplets so they changed from spherical to cylindrical and eventually break into two droplets. Then they could steer the droplets around and make them coalesce. I've always wanted to see some sort of diagram of rotating pressure waves or whatever that machine did.<br /> </li></li></li></ul><br />Do you suppose I will have to try to find the principal investigator's name and look for papers? I haven't had much luck trying to find web pages about this stuff.<br /><br /> <div class="Discussion_UserSignature"> </div>
