Combining a Fluoroalkylsiloxane and Ion Implantation for Hydrophilic/Hydrophobic Patterning

Cook M.J., Johnston J.H., Leveneur J., Victoria University of Wellington, NZ

We present a novel method of producing hydrophilic/hydrophobic patterning on several different substrates using a novel two-step process. The developed process involves a simple surface functionalization with a fluoroalkylsiloxane (FAS), followed by masked ion implantation. [...]

Micro Patterning of Organic Solvents on OLED Device Using EHD Inkjet Technology

Lee S-H., Nguyen X.H., Jo W., Ko H.S., Sungkyunkwan University, KR

Although there are many modes of the ejection mechanism from the EHD nozzle [2], a cone-jet mode, a pulse-jet mode and a micro-dripping mode have been analyzed by capturing the jetting phenomena using organic solvents [...]

A facile block copolymer inclusion technique for large scale monodisperse hexagonal arrays of superparamagnetic iron oxides nanodots

Ghoshal T., Maity T., Godsell J.F., Roy S., Morris M.A., University College Cork, IE

We demonstrate a simple and cost-effective route, based around block copolymer patterning, to create dense arrays of highly ordered iron oxide nanodots at substrate surface. The methodology creates hexagonally arranged features via a process of [...]

Nanomaterials can influence living biological systems with nanometer sensitivity

Sabella S., Brunetti V., Maiorano G., Rizzello L., Sorce B., Vecchio G., Galeone A., Cingolani R., Pompa P.P., Italian Institute of Technology, IT

We show the different response of human neuroblastoma cells line to gold surfaces with different levels of nanoroughness, finding out that neurons are capable to sense and actively respond to these nanotopography features, with a [...]

Patterning Technology for Nanomanufacturing

Smith H.I., Walsh M., Zhang F., Hourihan G., Ferrera J., Jaspan M., LumArray, US

We describe a new approach to patterning that circumvents the limitations of techniques that were developed for the semiconductor industry. The new approach, zone-plate-array lithograhy (ZPAL)will enable an expansion of applications of nanoscale science and [...]

Optimized Surface Patterning Tools for Sub-attoliter Volume Fluid Deposition

Adams M.L., University of South Alabama, US

Micromachined cantilever-based surface patterning tools were optimized to allow submicron diameter printing of fluids on various surfaces. A detailed fluidics model was used to analyze critical variables and determine the best method for optimization. Tools [...]

Spray-coating deposition for large area organic thin-film devices

Abdellah A., Baierl D., Fabel B., Lugli P., Scarpa G., Technische Universitaet Muenchen, DE

Organic electronic devices based on solution-processable polymers are among the most promising applications of organic semiconductors. Low-cost fabrication by means of simple coating and printing techniques is surely one of their greatest advantages. We report [...]

Stretegies for fabrication of nanostructures using focused ion beam technology

Gadgil V.J., Mesa+ Institute for Nanotechnology, NL

Recently FIB is increasingly being used for fabrication of nanosturctures and rapid prototyping. In the area of optical sciences, FIB is used for fabrication of 2D and 3D photonic devices. One of the problems in [...]

Micropatterning Layers by Flame Aerosol Deposition – Annealing

Tricoli A., Graf M., Mayer F., Kühne S., Hierlemann A., Pratsinis S.E., PTL, CH

The development of scalable methods, which effectively bind nanoparticles to surfaces and provide precise patterns, is a key step towards the commercial exploitation of the distinctive properties of nanoparticles. In this context, the direct deposition [...]

Electrostatic Induced Inkjet Printing System for Micro Patterning and Drop-On-Demand Jetting Characteristics

Choi J., Kim Y., Kim Y.J., Son S.U., Kim Y., Kim Y.J., Lee S., Byun D., Ko H.S., Sungkyunkwan University, KR

Printing technology is considered to be a key technology even in the field of electronics, materials processing, and bio applications. Inkjet printing is an interesting patterning technique for electronic devices because it requires no physical [...]
