Developing a rapid screening method for direct visualization of nanoparticles captured on filter media during occupational exposure assessments

Neu-Baker N.M., Eastlake A.C., Brenner S.A., SUNY Polytechnic Institute, Colleges of Nanoscale Science & Engineering (CNSE), US

As engineered nanomaterials (ENMs) are increasingly incorporated into manufacturing processes and consumer goods, the nanotechnology workforce is also growing, with 6 million workers anticipated by 2020, of which 2 million are projected to work in [...]

Pseudocapacitive random and aligned nano-porous electrode materials for supercapacitors

Saruhan B., Gönüllü Y., Arndt B., German Aerospace Center, DE

Commercial electric double layer capacitors store energy in an electric field. This is caused by charged particles arranged on two electrodes consisting mostly of carbon, in the form of a double layer. Such double layer [...]

Modulating the Near Infrared Reflective Properties of Metal Oxides for Surface Coating Applications

Nidhin M., Sangeetha S., Radhika S., Sreeram K.J., Nair B.U., Central Leather Research Institute (CSIR), IN

A colorant which is able to reflect a major portion of the near infrared radiation is today known as cool colorant. These colorants when coated on roof tops, automobiles, leather etc. reduce the demand for [...]

From the fabrication strategy to the device integration of gas nanosensors based on individual nanowires

Jiménez-Diaz R., Prades J.D., Casals O., Andreu T., Morante J.R., Mathur S., Fonseca L., Santander J., Barth S., Hernandez-Ramirez F., Romano-Rodriguez A., Universitat de Barcelona (UB), ES

In the last years, nanowires have emerged as potential building blocks of new devices and circuit architectures due to their performance derived from their reduced size and well-controlled chemical and physical properties [1]. Large efforts [...]

Novel Flame-Gradient Method for Synthesis of Metal Oxide Nanomaterials

Merchan-Merchan W., Saveliev A.V., Desai M., The University of Oklahoma, US

Various transition metal oxide nanostructures are synthesized using a novel probe-flame gradient method. An opposed flow flame of methane and oxygen enriched air provides a hightemperature reacting environment forming various structures directly on the surface [...]

A Novel Method for the Production of a Vast Array of Metal, Metal Oxide, and Mixed-Metal Oxide Nanoparticles

Woodfield B.F., Liu S., Boerio-Goates J., Astle L., Brigham Young University, US

In this paper we discuss the materials that can now be produced using a novel method for producing large quantities of high-purity metal, metal oxide, and mixed-metal oxide particles. These nanoparticles are uniform in size [...]

Vapor Deposited Nanolaminates

Kobrin B., Grimes M., Dangaria N., Applied Microstructures, Inc., US

We present the latest developments in nanocoatings deposition technology, realized using Molecular Vapor Deposition (MVD®) method. Multi-layer nanolaminates of metal oxides (alumina, titania, silicon oxide, …etc.) and self-assembled monolayers (SAMs) sequentially deposited using an automated [...]

Preparation of transparent electrodes based on CNT-s doped metal oxides

Paalo M., Tätte T., Visk U., Lõhmus A., Lõhmus R., Lõhmus A., Lõhmus R., Kink I., University of Tartu, EE

In recent year’s electrically conductive and transparent electrodes has been one of the most important issues in optoelectronics. High price of ITO have set the search for alternative materials into focus. CNT-s has been used [...]

Low Temperature Nanolayers of Metal Oxides By MVD

Kobrin B., Dangaria N., Chinn J., Applied Microstructures, Inc., US

Molecular Vapor Deposition (MVDTM) techniques and equipment have been successfully used for many coating applications in the MEMS, disk drive, and nano-imprint lithography fields. By exploiting the ability of MVD to deposit an in-situ metal [...]
