Inkjet Printed Devices for Armament Applications

Zunino III J.L., Schmidt D.P., Petrock A.M., Fuchs B.E., U.S. Army, US

U.S. Army Armaments Research Development and Engineering Center (ARDEC) is developing the capability to custom design, manufacture and integrate novel technologies into functional devices for the creation and advancement of active systems, including printed electronics, [...]

Stable colloidal dispersion of luminescing silicon nanoparticles for inkjet printing

Gupta A., Khalil A.S.G., Winterer M., Wiggers H., Universität Duisburg-Essen, DE

In this study, we synthesized Si-NPs with mean diameter about 4.2 nm in a microwave plasma reactor. In order to disperse these Si-NPs in organic solvent, the surface of freshly etched Si-NPs was modified with [...]

Ink-jet printed ZnO Nanoparticle Thin Films for Sensing Applications

Hartner S., Khalil A.S.G., Ali M., Winterer M., Wiggers H., University Duisburg-Essen, DE

Stable aqueous dispersions of ZnO NPs are successfully prepared with a new polymeric stabilizer. The dispersions are stable for at least 2 months without any observable sedimentation. The zeta potential and the size of the [...]

Rapid Metallization of Silver and Copper Nano Inks by Surface Wave Plasma Sintering

Cho J-M, Lee Y.I., Song Y.A., Kim D-H., Kim S.E., Kim T-H., Kim D-H., Kim S.E., Kim T-H., Kim D-H., Kim S.E., Kim T-H., Samsung Electro-mechanics Co. Ltd., KR

Inkjet printing technique of nano-sized silver or copper particles currently has had lots of attention as an alternative to conventional lithography and etching process for electronic devices in view of reducing costs. The inkjet-printed nano [...]

Printed sensor and liquid actuation on natural fiber based substrate

Saarinen J.J., Ihalainen P., Määttänen A., Bollström R., Peltonen J., Abo Akademi University, FI

Recently we have developed a new biobased substrate for printed functionality that, compared to the conventional plastic films, is recyclable and renewable based on natural fibers. Inkjet printed transistor functionality has already been realized and [...]

Drop Formation and Control of Non-Newtonian Fluid

Gao J., Ng K., Eastman Kodak Company, US

It is well known that fluid jets tend to break up into droplets of multiple sizes. However, the ability to make and control individual droplets from arrays of such jets in speed, number, and size [...]

Modeling Drop Generation at the Microscale

Hanchak M.S., Furlani E.P., Eastman Kodak Company, US

In this presentation a numerical model is described for predicting drop generation from microscale liquid jets of Newtonian fluid. The model uses a one-dimensional slender-jet approximation to obtain the equations of motion for the free-surface [...]

Manipulating Optical Properties of Luminescent Nanoparticle Substrates through Inkjet Printing

Guzan K., Sumerel J., Davis L., Hoertz P., Mills K., Magnus-Aryitey D., RTI International, US

In this work, an ink jet printer has been used to deposit patterns of photoluminescent particles onto nanofiber substrates allowing control of correlated color temperature (CCT) and color rendering index (CRI) of the resultant photoluminescent [...]

A Finite Element Analysis for a Supercritical Particulate Process

Bakhbakhi Y., King Saud University, SA

Nonconventional processing methods can lead to the development of materials with unique chemical, physical or mechanical characteristics that make them suitable for specialized applications. One such method is crystallization with supercritical fluids (SCFs), where the [...]
