Imbibition dynamics of nano-particulate ink-jet drops on micro-porous media

Hsiao W.-K., Hoath S.D., Martin G.D., Hutchings I.M., Jones S., Chilton N., University of Cambridge, UK

Our study represents the first investigation of imbibition of ink-jet deposited nano-Cu colloid drops on a proprietary coated paper substrate. Using high speed imaging apparatus to capture the depsoition of ink-jet drops, the timescales of [...]

Expanding Capabilities of a Machine Vision System for Analysis of Drops-in-flight

Kipman Y., Mehta P., Wang S-W., ImageXpert Inc., US

Measuring in-flight characteristics of ink drops under different conditions can provide insight into relationships and interactions, helping drive system and consumable optimization for manufacturers of inkjet heads, head driver electronics, inks, and integrated printing and [...]

Advancements in Ink-Jet Deposition of Carbon Nanotube Materials for Printed Electronics

Turner S., Brewer Science, US

Advancements in the separation, purification, and post processing of metallic carbon nanotubes are enabling these materials to be used in new printed electronic devices. While CNTs have been researched for over 10 years, recent innovations [...]

New developments in inkjet of deposits carried out under localised extraction or helium

Conedera V., Mesnilgrente F., Fadel P., Fabre N., LAAS/CNRS, FR

In inkjet, inks used are based on aqueous or organic solvents. Solvents with low boiling point present the drawback of drying quickly and then we can observe the clogging of the orifices of ink jet [...]

Customer-focused batch production via printing technology

Kain A., Mueller C., Reinecke H., University of Freiburg, DE

This paper presents a hot melt printing technology which provides a customer-focused batch production for circuit layers assembly, silicon surface structuring and 3-dimensional surface modification. By the forming properties of hot melt inks and in [...]

Nano-Patterning of NaCl Using Nanopipette based on the QTF-AFM System

An S.M., Geol W.H. Jhe M., Department of Physics and Astronomy, Seoul National University, KR

We made nano-patterning of NaCl on the clean Au-Substrate & Mica using Nanopipette based on the QTF-AFM (Quartz Tunning Fork-Atomic Force Microscopy) nano-scaled water ejection system. The NaCl is ionized in liquid solution (we used [...]

Machine Vision System for Analysis of Drops-in-flight and Wetting Visualization

Kipman Y., ImageXpert Inc., US

An integrated, machine-vision system, JetXpert, has been developed for the visualization of faceplate wetting and the measurement of drops-in-flight. For print head wetting, the system uses a camera and light source set at an angle [...]

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 [...]
