MIT boffins take electrospray nozzles out of the cleanroom, into the 3D printer

The process for producing triple-layer drug-delivery particles and materials for tissue regeneration could get easier, thanks to a new advance in creating the electrospray nozzles used to make them. A team of MIT researchers has now used a 3D resin printer to output tiny electrospray nozzles without the expensive cleanrooms they normally require. A team led by MIT principal research scientist Dr. Luis Fernando Velásquez-García detailed its work developing tiny arrays of triaxial electrospray...

Common plastics soak up ballistic impacts thanks to a cross-linking molecule

Common plastics soak up ballistic impacts thanks to a cross-linking molecule Sadie Harley Scientific Editor Robert Egan Associate Editor With help from a novel cross-linking molecule, MIT chemists have shown they can substantially improve the ballistic impact resistance of common polymers, including polystyrene and a type of rubber used to make shoe soles. Polystyrene is a hard, glassy polymer that is used to make many types of plastic containers, such as bottles and mugs, as well as...

For satellites as small as a briefcase, getting around in space just got a whole lot easier

For satellites as small as a briefcase, getting around in space just got a whole lot easier Lisa Lock Scientific Editor Robert Egan Associate Editor MIT engineers are testing a new propulsion system that combines the power and speed of conventional chemical thrusters with the precision and fuel-efficiency of electrical thrusters. The system could enable the design of nimbler, more flexible small satellites, which could perform both fast, powerful maneuvers and slower, precise adjustments,...

3D-printed nozzle array could streamline production of drug-delivery microparticles

3D-printed nozzle array could streamline production of drug-delivery microparticles Lisa Lock Scientific Editor Robert Egan Associate Editor MIT researchers have demonstrated a low-cost design for specialized electronic nozzles, called triaxial electrospray emitters, that could be used to manufacture time-release drug-delivery particles or self-healing materials efficiently and at scale. Triaxial electrospray emitters use electricity to precisely dispense three liquids from microscopic...
