Recent Highlights

"Smart" paper

The chip-in-paper process based on our laser-enabled advanced packaging (LEAP) Flexible Hybrid Electronics manufacturing technology allows for embedding ultra-thin, ultra-small electronic components, including ICs, inside a sheet of a regular paper for applications such as "smart" security and financial products.

Feautured in BBC News, Discovery News, RFID Journal, IEEE Spectrum, Pratique and Futura (France), SCM Journal (Korea), La Stampa (Italy), Krone (Austria), many media outlets and blogs from around the world.

LEAP and other Flexible Hybrid Electronics technologies are currently under commercialization by Uniqarta, Inc.

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.
