Rapid processing using Intense Pulsed Light

Druffel T., University of Louisville, US

The Intense Pulsed Light (IPL) technology is well suited to continuous manufacturing platforms such as roll-to-roll due to its very large processing area and rapid processing time scales. The IPL technique delivers high energy pulses [...]

Rapid processing of perovskite thin films for applications in PV

Druffel T., Lavery B., University of Louisville, US

Perovskite solar cells have the possibility of becoming the next generation of industrial solar cells due to their ease of manufacturing, use of common materials, and respectable efficiencies. Since the first report of perovskite solar [...]

Scalable Polymer Patterning (SP2)

Mead J., Barry C., University of Massachusetts-Lowell, US

Polymeric materials are easily fabricated into a wide array of structures for numerous applications. The bulk properties can be tailored for preparing novel structures and substrates for use as substrates for 3D printing. Particularly, the [...]

Manufacturing of a Continuous CNT Rollstock

Chan E.M., General Nano, US

In Q1 2014, General Nano was awarded a Commercial Readiness Program by the Air Force to scale uniquely long and pure MWCNTs. To accelerate time to commercialization and to minimize capital expenditure, a strategy chosen [...]

Polymer Based Continuous Offset Printing

Mead J., Barry C., University of Massachusetts-Lowell, US
