Results to Date: Nickel Inks Successful ink-jet printing on low temperature substrates such as paper Credit Card numeric images successfully printed Printing of Nano nickel based films using the Dimatix DMP system.

Silicon Ink Formulation and Printing IM Silicon inks already achieved mobility approx 1 cm 2 /V-s Inkjet printing successfully achieved with Dimatix DMP2800 Inks can be p-type or n-type doped IM also have experience of producing ink formulations for other printing techniques such as gravure

LightTouch Application of IM ink to produce narrow lines for one sided touch sensitive transparent display systems (with MSOLV, Touchnetix) COPE Conformal printing for aerospace applications (BAe, Sun Chemical++) PROCID Disease detection systems for (with Leeds U, ELISHA, TRG, TNG, P1, Amies Innovation)

NANOFLAM Nano phosphors for biotags for R&D in bio systems research (Bath U, AbCam) HYPERCONNECT Thermal and electrical connections systems for flip chips (LORD, IBM) LAPTRANS Application of IML ink to OLED Lighting systems (Orbotech, PEL, BU)

Light manipulation and conversion to maximise DSSC energy output for DSSC Grand Challenge Programme Part 2 Down Converting Up Converting Up Converting

Development work on novel nanoscale copper metal inks complete Ink jet / screen product now available Demonstrators successful (reel to reel) Curing methods addressed Application development underway Biosensors, touchscreens, PV Industry proof of concept studies underway Nickel and silicon systems in development IM always looking for partners to address new applications and opportunities
