LASER-ENABLED ADVANCED PACKAGING (LEAP) FOR ULTRA-LOW COST MICROELECTRONICS

RFID “banknotes”: a chip-in-paper concept realized using LEAP. The image at the bottom is a backlit photo clearly showing the embedded RFID antenna and chip. (larger image) The world's first electronic device (an RFID tag) packaged using lasers. The contactless laser-enabled advanced packaging (LEAP) technology has been developed by my team at CNSE.

NANOMATERIALS & APPLICATIONS

NDSU Aerogels
The first transparent silica aerogel synthesized at NDSU in November 2010 Phosphorescence in an 365nm-excited silica aerogel with dispersed SiO2-coated, 2-8 μm SrAl2O4:Eu,Dy crystals.
The applications of advanced nanocomposite materials based on transparent silica aerogels have recently become an exciting area of research for me. One of my projects is related to the synthesis and characterization of nano-structured materials consisting of quantum dots and other nanocrystalline materials uniformly and randomly dispersed in a virtually transparent silica aerogel matrix.
