I’m still writing this up, but I wanted to share a short video of our recent work modeling suction cups using FEBio, an open-source finite element modeling tool. Check out this biomimetic cuttlefish suction cup:

How to align a 4F optical system for digital inline holographic microscopy.
The goal of a 4F system in holography is to generate a collimated beam of single-wavelength light, shine it through a sample, and then magnify and refocus this light onto a camera sensor. When the collimated light hits the sample, it creates concentric rings around the objects known as diffraction patterns or Airy discs, like this: These diffraction patterns provide […]
IEC Reactor Update
After a bit of a hiatus, we’re making good progress on the reactor! We recently replaced the cathode and feedthrough with a titanium surgical rod and a titanium bicycle stem spacer. Alumina tubing at this size is extraordinarily expensive, so we repurposed TIG welding nozzles for the shielding. I’m quite impressed with the results, but the new materials have added […]
