Reliable nanoscale electrical characterization using Graphene-coated Atomic Force Microscope tips

Lanza M., Bayerl A., Reguant M., Lv P., Rubio C., Porti M., Nafria M., Duan H.L., Peking University, CN

Electrical characterization at the nanoscale is an essential procedure for analyzing the performance of many materials used at both industry and academia. In this field, one of the most powerful tools is the Conductive Atomic [...]

Low-Cost Nano-Manufacturing of Surface Acoustic Wave Devices by Use of Jet & Flash Nano Imprint Lithography

Pedersen C.M., Braun L., Ballandras S., Plessky V., De Joffrey P., Boillot P., Renaud S., Girardet E., Bro T.H., Bilenberg B., Gegot F., Davis Z.J., Danish Technological Institute, DK

Surface acoustic wave (SAW) devices have many applications and can be found in common consumer electronics such as mobile phones, WiFi and GPS. Beside its use in electronics they can also be used as a [...]

Fabrication and Characterization of PEDOT Nanowires Based on Self Assembled Peptide Nanotube Lithography

Ormstrup Christiansen N., Andersen K.B., Castillo-León J., Svendsen W.E., Rozlosnik N., Technical University of Denmark, DK

In this article we demonstrate the use of self-assembled peptide nanotube structures as a masking material in a rapid, mild and low cost fabrication of PEDOT:TsO nanowire device. In this new fabrication approach the PEDOT:TsO [...]

Nanopatterned coatings for advanced glass products

McMackin I., Geddes J., Aryal M., Seitz O., Kobrin B., Rolith, Inc., US

A wide variety of glass products would greatly benefit from coatings that offer anti-reflective, anti-glare, anti-fog, anti-ice, self-cleaning, and other advanced functions. State-of-the-art coatings do not meet desired performance characteristics or cannot be applied over [...]

Patterning of Periodic Structures Using Continuously Moving Stage

Klingfus J., Sanabia J.E., Burcham K.E., Kahl M., Raith USA, US

A unique EBL writing technique is presented which is ideally suited to patterns of a periodic nature such as gratings, holograms, photonic crystals, sieves, etc. In contrast to classic step-and-write EBL strategies, this technique writes [...]

The C-TVA plasma source – a chemical vacuum thin film deposition tool

Surdu-Bob C.C., Badulescu M., INFLPR, RO

It is presented here for the first time the deposition of oxides, nitrides and oxinitride thin films by a new plasma source based on Thermionic Vacuum Arc plasma (TVA), called Compact-TVA (C-TVA). The source uses [...]

Synthesis of Stabilized Silver nanoparticles exposed to Hydrochloric Acid

Atta A.M., Allohedan H.A., Ezat A., Issa Z.A., King Saud Unversity, SA

The bioavailability of ingested silver nanoparticles (AgNPs) depends in large part on initial particle size, shape and surface coating, properties which will influence aggregation, solubility and chemical composition during transit of the gastrointestinal tract. In [...]

Characteristics of Grooving by Diamond Needle-Tip with Various Tip Shapes and Grooving Parameters

Mladenovic V., R&D - New technologies, SI

The fundamental goal of this study is to present effects on the material AISI with one of the micro-machining methods in modern security printing technology, such card production, needle tip engraving. This method is basically [...]

Electrically conductive polypropylene fibers and tapes

Martin F., Centre of Advanced Surface Engineering-AIN, ES

We report here the development of electrically conductive polypropylene MWCNT fibers and tapes with conductivities up to 70 S/m (8% wt) with a percolation threshold at 0.5%. Using a solution compounding method assisted by sonication [...]

Template-Free Single-Step Fabrication of Metal Oxide Hollow Nanospheres and Nanofoams

Jiang X., Changzhou University, CN

Hollow nanospheres and nanofoams possess characteristics such as low density, high surface area and adjustable refractive index that make them attractive to tune their mechanical, optical, electrical, and chemical properties for applications ranging from drug [...]
