Characterizing Nanoparticle Emissions from Burning Polymer Nanocomposites
Nyden M.R., Harris R.H., Kim Y-S, Davis R.D., Marsh N.D., Zammarano M., National Institute of Standards and Technology, US
At Nanotech 2009, we presented evidence that CNFs used as fire retardants in polyurethane foam (PUF), were destroyed in the flames and, therefore, were not released when CNF containing foams are burned under well-ventilated conditions. [...]
Surface tailoring of carbon fabric reinforced PES composites with micro and nano PTFE fillers
Carbon fabric reinforced polymers (CFRPs) are being increasingly used as advanced composites for structural materials applications, especially in aircraft industry because of very high specific strength and modulus apart from their higher thermal conductivity, corrosion [...]
Role of Nanoparticles in Life Cycle of Nanocomposites
Gu X., Chen G., Zhao M., Watson S.S., Zhe D., Stutzman P.E., Nguyen T., Chin J.W., Martin J.W., NIST, US
This study is to investigate the role of ZnO nanoparticles in the life cycle of a waterborne polyurethane (PU) nanocomposite during UV exposure. The specimens were exposed to the NIST SPHERE (Simulated Photodegradation via High [...]
Integration of SWCNT into Olefin polymer composites
Single Walled Carbon NanoTubes (SWCNT) have covalently integrated into polyolefin such as PP and PE. SWCNTs are homogeneously distributed in the polymer matrix without interface problem due to covalently anchor.
Chemical and Phase Transformations of Nanocrystalline Oxides in a Carbon Nanoreactor
The application of nanocrystalline oxides as precursors for synthesis of new nanomaterials with the preservation of the dimensions of the initial nanoparticles is of considerable interest. Its main problem is the sintering and growth of [...]
Surface Modification and Performance Analysis of Jute Based Nanophased Green Composite
The surface modification of jute fibers was accomplished by performing subsequent chemical treatments such as detergent washing, dewaxing, alkali and acetic acid treatment. The morphology of the modified surface was examined using the scanning electron [...]
Thin-Film Deposition on Nanoparticles in Low-Pressure Plasma
To achieve the desirable optical, mechanical, thermal, and electrical properties that are unattainable in the nanoparticles alone, Matsoukas group uses plasma enhanced chemical vapor deposition technique, PECVD. Particles are introduced into two different reactors that [...]
An experimental and theoretical study of the inhibition mechanism of organic substances in concrete
Diamanti M.V., Ormellese M., Perez-Rosales E.A., Pedeferri MP., Raffaini G., Ganazzoli F., Politecnico di Milano, IT
Corrosion inhibitors are one of the preventative techniques used to prevent chloride-induced corrosion in reinforced concrete structures. Several commercial inhibitors are available on the market, but their efficiency as well as their inhibitive mechanism are [...]
Chemical structure of ZnO nanorod array on a DSSC photoanode
Chang Y-H, Liao C-Y, Wang H.P., Wei Y-L, Fukushima Y., Guo T-F, Chiang Y-F, National Cheng Kung University, TW
The main objective of the present work was to study speciation of ZnO nanorods and the photoexcited electron transfer between photosensitive dyes and the ZnO nanorod arrays (Fig. 1) on the photoanode of a dye-sensitized [...]
