We demonstrate ink-jet printing as a viable method for large area fabrication of graphene devices. We produce a graphene-based ink by liquid phase exfoliation of graphite in N-Methylpyrrolidone. We use it to print thin-film transistors, with mobilities up to∼95cmVs, as well as transparent and conductive patterns, with∼80% transmittance and∼30kΩ/ sheet resistance. This paves the way to all-print...

The 3D printing is a combination of digital technology, material science, intelligent manufacturing and control of opto-mechatronics systems. It is called the third industrial revolution from the view of the Economist Journal. A color 3D printing machine may provide the necessary support for high value-added industrial and commercial design, architectural design, personal boutique, and 3D artis...

©2005, IS&T—The Society for Imaging Science and Technology pigment particle size distribution, particle shape, binder type, film shrinkage, drying conditions, coating holdout, and coating weight.6 Research groups studying the roughness and its effect on gloss have agreed upon the fact that common roughness numbers are insufficient to predict gloss.9 It sometimes occurs that the rougher surfaces...

The color inconstancy of prints is related to the ink spectral properties and the lookup table for multiink printing systems. In this paper, color inconstancy was investigated for several ink-jet printers based on their ink set and the default lookup tables. A virtual model for each printer was created to determine the range of color inconstancy that a specific ink set could achieve. The color ...

A surface-reaction system in a nanoliter water pool using an ink-jet microchip was developed. The reaction system in the nanodroplets formed on a poly(dimethylsiloxane) (PDMS) coated glass slide increased the diffusion-controlled reaction without using a nano-pump, specialized connector or highly sensitive detector. When nanoliter droplets were placed on the PDMS surface with a distance of 100 ...

Textile printing systems are needed that will meet the requirements of time-driven, demand activated manufacturing. Electrophotography and ink-jet printing are technologies that have the potential of meeting these requirements. Textile-specific, electrophotographic and ink-jet printing toners/inks must be developed if these technologies are to gain acceptance in the textile industry. The develo...

Emerging technologies of net-form manufacturing and electronic packaging rely on the use of precisely deposited molten metal droplets with sizes on the order of 100 μm in diameter. In many technological realizations, closely spaced droplets are electrostatically charged and deflected onto a substrate in a manner similar to ink-jet printing in order to “print” fine features onto a board for elec...
