Printed sensor and liquid actuation on natural fiber based substrate

Saarinen J.J., Ihalainen P., Määttänen A., Bollström R., Peltonen J., Abo Akademi University, FI

Recently we have developed a new biobased substrate for printed functionality that, compared to the conventional plastic films, is recyclable and renewable based on natural fibers. Inkjet printed transistor functionality has already been realized and [...]

Nanoparticle release from nano-containing product, introduction to an energetic approach

Gheerardyn L., Le Bihan O., Dore E., Morgeneyer M., INERIS, FR

The use of nanoparticles in manufactured products becomes more and more frequent and could lead to new potential risks for the workers, the consumers and the environment. This study focused on the R&D process of [...]

Development of Durable Nanostructured Superhydrophobic Self-Cleaning Surfaces in Glass Substrates

Jiang Y.D., White M., Hunt A.T., Kitada M., Fitz T., nGimat Co., US

Superhydrophobic self-cleaning surfaces have wide applications in architectural and automotive windows and solar panels, etc. Many existing hydrophobic coatings either have low transmittance which is not suitable for windows or not as hydrophobic as lotus [...]

Nanoscale Silver Coatings on Synthetic Fibers

Amberg M., Körner E., Hegemann D., Heuberger M., Empa, Swiss Federal Laboratories for Materials Testing and Research, CH

In this work, we present two different low-pressure plasma processes that are used to obtain nanoscale coatings on the special geometry of fibers. A 100-200nm thick smooth silver coating is produced and its electromechanical as [...]

From Micro to Nano Magnetic Spheres: Size-Controllable Synthesis, Multilayer Coatings, and Biomedical Applications

Leung K.C.F., Xuan S., The Chinese University of Hong Kong, HK

Magnetic material has become a particular important research area and is attracting a great deal of attentions because of their potential technological applications, such as in ferrofluids, colored pigments, high-density magnetic recording media, chemical sensors, [...]

Gels of Carbon Nanotubes and Nonionic Surfactant and High-quality Carbon Nanotube Films Prepared by Gel Coating

Ouyang J., National University of Singapore, SG

Processing of large-scale carbon nanotubes (CNTs) are very important for the application of CNTs in various aspects. Here, we report CNT gels by dispersing CNTs in various nonionic surfactants. High-quality CNT films were prepared by [...]

Environmental Digital Pulsed Force Mode AFM in Biomedical Coatings Research

Haugstad G., Wormuth K., University of Minnesota, US

We report ongoing methodological developments using Digital Pulsed Force Mode AFM of model coatings containing the drug dexamethasone dispersed in polylactide (biodegradable), poly(butylmethacrylate) (PBMA), and PBMA/poly(laurel methacrylate) (PLMA) blends. Studies include (1) multi-technique analyses, understanding [...]

Silica-coated Ag nanoparticles by scalable flame technology

Sotiriou G.A., Camenzind A., Pratsinis S.E., ETH Zürich, CH

Silica coated silver nanoparticles have been synthesized in one step, by using flame spray pyrolysis. By controlling the production parameters, different sizes and different coating thicknesses were achieved. The particles were characterized with TEM/STEM, EDX [...]

Flame Synthesis and Coating of Nanostructured Particles in One Step

Teleki A., Buesser B., Heine M., Krumeich F., Akhtar M.K., Pratsinis S.E., ETH Zürich, CH

Coating of flame-made nanostructured particles has been achieved in one step by a scalable aerosol process. Rutile TiO2 particles made by flame spray pyrolysis (FSP) were coated in a single step with SiO2 layers in [...]

Hermetically-Coated Superparamagnetic Fe2O3 Particles with SiO2 Nanofilms

Teleki A., Suter M., Kidambi P.R., Ergeneman O., Krumeich F., Nelson B.J., Pratsinis S.E., ETH Zürich, CH

Magnetic nanoparticles are frequently coated with SiO2 to improve their functionality and bio-compatibility in a range of biomedical and polymer nanocomposite applications. In this paper, a scalable flame aerosol technology is used to produce highly [...]
