A precisely controlled metallic nanomesh was fabricated by using nanosphere lithography to pattern the silver thin film to form hexagonal nanohole arrays with excellent uniformity, high conductivity and good transparency. An Alq(3) based OLED, with the silver nanomesh electrode of high ðll factor of 70.2% demonstrated a considerable luminous efðciency of 4.8 cd/A, which is 60.9% higher than the referenced device with ITO anode. The periodical nanohole array not only increased the transparency but also helped extracting surface plasmonic wave in organic layers. By attaching the microlens array to further extract the trapped light in substrate, the extraction efficiency enhancement of device with nanomesh anode was 73.8% higher than 50.2% of the referenced device with ITO anode. And the overall current efficiency of device with nanomesh anode was 87.7% higher than traditional ITO based device.

In this study, a Tosflex (a perfluoro-anion-exchange membrane) modified glassy carbon electrode has been used to detect 2-naphthalenol (2-naphthol) in aqueous solutions in order to demonstrate the electroanalytical application of Tosflex. 2-naphthol polymerizes upon electrochemical oxidation at a glassy carbon electrode; however, the current related to this oxidation is too small for analytical purpose at low concentration level. A Tosflex polymer modified glassy carbon electrode (TFGCE) was found of having capability to improve the detection limit because 2-naphthol molecules deprotonated in basic solutions to form 2-naphtholate anions that were accumulated to TFGCE by the anion-exchange characteristic of Tosflex. The accumulated 2-naphtholate anions were determined with the following differential pulse voltammetry. With 3 minutes accumulation at þ 0.05 V, the dependence of oxidation current versus concentration was linear from 8 Â 10 À7 M to 1 Â 10 À5 M with a regression coefficient of 0.999 and a detection limit of 2 Â 10 À7 M. Unlike many other anion-exchange polymer modified electrodes, the TFGCE is stable at highly basic condition.

Non-contact, direct-write aerosol jet (AJ) printing technology using a variety of functional nanomaterial inks has been regarded as one of the most promising approaches for large-area additive manufacturing. The development and atomization of inks have a considerable effect on the printing quality. Therefore, in this study, the effect of a specific ratio of silver nanoparticle ink and a cosolvent of propylene glycol monomethyl ether (PGME) and ethylene glycol (EG) was investigated. The results indicated that the proportion of the solvent in the silver nanoparticle ink could affect the electrical characteristics of the printed lines. The prepared conductive ink with 95% silver nanoparticle ink and 5% co-solvent at a curing temperature of 180°C demonstrated superior electrical conductivity and adhesion on the substrate.
