Water desalination - selective removal of specific Ions
Selective water treatment, which removes more problematic ions preferentially over others, is an important goal towards next generation, energy efficient water treatment systems. Current treatment techniques rely on chemical sedimentation or membrane separation, the latter of which is used in...

Wearable stretchable microneedles-based platform
Microneedles devices to monitor materials in the interstitial fluid or inject materials to it are widely used for a range of medical conditions. Those are hollow microneedles as they need to pass fluids from and to the body. As such...
