MIT News: Fast, cheap nanomanufacturing Arrays of tiny conical tips that eject ionized materials could fabricate nanoscale devices cheaply.

Luis Fernando Velásquez-García’s group at MIT’s Microsystems Technology Laboratories (MTL) develops dense arrays of microscopic cones that harness electrostatic forces to eject streams of ions. The technology has a range of promising applications: depositing or etching features onto nanoscale mechanical devices; spinning out nanofibers for use in water filters, body armor, and “smart” textiles; or

ILP Institute Insider: Mass Spectrometry in Your Hand Electrospray arrays can dramatically downsize systems and costs for onsite chemical analysis — and many other applications.

If you’re out in the field doing environmental testing, food checks, forensic work or other chemical analysis, mass spectrometry is an extremely accurate detection tool with one huge drawback: You can lose days in sending samples back to the lab for analysis. MIT researchers now have developed technologies that promise to enable mass spectrometers that

Our X-Ray work is featured in IEEE Spectrum!

Our work on advanced X-ray generators was featured in the March 2014 issue of the magazine IEEE Spectrum, in the article “Less Is More With Next-Generation Medical X-rays” by Mark Anderson. The X-ray that imaged your father’s broken leg when he was a kid isn’t fundamentally different from the one at your doctor’s office today—other than that
