Aerosolization of Carbon Nanotubes for the Development of Reference Air Samples

Cavaliere M.R., Compton S.P., MVA Scientific Consultants, US

Reports on the inhalation risks associated with carbon nanotubes (CNTs) express concern for exposures throughout the lifetime of CNTs and CNT-enabled products. The ability to quantify airborne exposures to workers and consumers will be a [...]

Physico-chemical Characterization of Extracts of Silver Nanoparticle Containing Medical Devices

Casey B.J., Jayanti P., Sussman E.M., Dair B.J., U.S. Food and Drug Administration, US

The main goal of this research was to gain a better understanding of the extraction profile of medical devices containing silver nanoparticles. Multiple silver nanoparticle containing medical devices were incubated in various extract solutions (water, [...]

The Study of Surface Accumulated Silica Nanoparticles from “Weathered” Polymer Nanocomposites Using ICP-OES

Rabb S.A., Stanley D., Sung L., Nguyen T., Yu L.L., National Institute of Standards and Technology, US

The impact of nanoparticles on the environment and, more importantly, the human population has been of great interest for the past few years. Release of these nanoparticles from different materials from wear or climate exposure [...]

Nanoaerosol release characteristics of wallpaper coated with TiO2 nanoparticles in an air-jet simulated test chamber

Bae G.N., Park S.H., Lee S.B., Kim J.B., Korea Institute of Science and Technology, KR

Consumer nanoproducts are interested in public health aspects. In Korea, wallpaper is a popular construction material of housing. Wallpaper is well known to emit various volatile organic compounds and carbonyl compounds. Some wallpaper is coated [...]

Multi-method analysis of multiwall carbon nanotube polymer nanocomposite after photodegradation

Petersen E.J., Lam T., Gorham J., Scott K., Long C., Sharma R., Sung L.P., Liddle J.A., Nguyen T., National Institute of Standards and Technology, US

Nanomaterials can be used as nanofillers to enhance the properties of polymeric materials. However, the effect of weathering on nanocomposites and the potential for nanomaterial release is not yet well known. This stems partly from [...]

Printed Gas Sensors for the Trillion Sensor Universe

Stetter E.F., Stetter J.R., Stetter E.F., Stetter J.R., Findlay M., Patel V., KWJ Engineering Inc. & SPEC Sensors LLC, US

Estimates predict that within a few years, we will need trillions of sensors to match the global development of wireless communications and computation. Chemical and gas sensors are an integral part of this need for [...]

Stretchable Electronics

Liang J., Li L., Liang J., Hajagos J., Niu X., Yu Z., Pei Q., University of California, Los Angeles, US

The emergence of devices that combine elasticity with electronic or optoelectronic properties offers exciting new opportunities for applications, but brings significant materials challenges. We will report (1) an elastomeric transparent conductor as a radically new [...]

Fully Integrated Embroidery Process for Smart Textiles

Trindade I.G., Spranger P., Martins F., Miguel R., Pereira M., Santos Silva M., Universidade da Beira Interior, PT

In this article, a compact textile system produced with a single embroidery digital machine and high design and integration versatility is presented. Clothing integrating textile electrodes made by seamless knitting has been proposed to monitor [...]

High Performance Organic Transistors based on Molecular Doping

Lussem B., Tietze M., Kleemann H., Fischer A., Gunther A., Leo K., Kent State University, US

Organic transistors hold the promise of enabling the field of flexible electronics. However, despite significant progress in the past, the performance and reliability of organic transistors has to be improved further to turn the dream [...]

A method to produce microelectronic devices on textile and paper substrates

Trindade I.G., Miguel R., Lucas J., Pereira M., Santos Silva M., Universidade da Beira Interior, PT

In this article, electrically conducting coatings of poly(3, 4 – ethylenedioxythiophene) (PEDOT) were synthetized on textile substrates by the vapor phase polymerization (VPP) method, using water as solvent. The VPP method is considerably more sustainable [...]
