Transverse Elastic Modulus of Tobacco Mosaic Virus Superlattice

Wang H., Wang X., Wang H., Wang X., North Dakota State University, US

Tobacco mosaic virus (TMV) and TMV-derived materials have demonstrated their great potential in biomedical applications, where the mechanical property is one of the determining factors for their proper functionalities and structural integrity. Recently, it has [...]

The distribution of nano size clusters in deformed FeCu alloy by small angle neutron scattering

Park D.G., Song H., Vertesy G., Kobayashi S., Takahashi S., Korea Atomic Energy Research Institute (KAERI), KR

Fe-Cu alloys are commonly used for a simulation of radiation damage of reactor pressure vessel (RPV) because a neutron irradiation enhances the copper rich precipitates (CRPs) with the sizes of several nanometer which is known [...]

Microscopic Characterization of Nanocomposite based on the Mixture of Carbon Nanotube and Rosette Nanotube

Cho J.-Y., Yamazaki T., Duque J.G., Doorn S., Das S., Green M., Fenniri H., National Institute for Nanotechnology, CA

In this paper, it was demonstrated that the self-assembled organic rosette nanotube (RNT) can encapsulate single-walled carbon nanotubes (SWNTs) and form nanocomposites. Importantly, the RNTs were found to hold their supramolecular architectures. To understand how [...]

Novel Carbon-Aluminum Materials

Jasiuk I., Nilufar S., Salamanca-Riba L., Isaacs R., Siddiqi S., University of Illinois at Urbana-Champaign, US

We characterized novel metal carbon materials called covetics. More specifically we study warm rolled Al 7075-carbon materials containing up to 5 wt% C. At macroscale we measured mechanical properties: Young’s modulus, ultimate tensile strength (UTS), [...]

Measuring Resistive Characteristics of Silicon Nanowire by Applying Electrostatic Tensile Device and Broadband Test Signal

Roinila T., Verho J., Vilkko M., Kallio P., Lekkala J., Zeng H., Yu X., Li T., Wang Y., Tampere University of Technology, FI

Silicon nanowires have attracted significant attention by the electronics industry due to the need for ever-smaller electronics components and devices. It has been shown that nanostructures reveal mechanical and electrical properties that are significantly different [...]

Extending the Lifetime of Zeta Potential Electrodes

Bodycomb J., Bruno D., Treviranus I., Bumiller M., Horiba Scientific, US

Nanoparticle development and manufacturing require appropriate particle characterization techniques to determine if design or quality goals are being met. One important aspect of many nanoparticle systems is the zeta potential, a measure of surface charge. [...]

Monitoring nanoparticle growth in a microreactor by combined micro-SAXS and micro-Raman techniques

Reynolds M., Di Cola E., Sztucki M., Gourrier A., Montero C., Burghammer M., European Synchrotron Radiation Facility, FR

Noble metal nanoparticles have been extensively exploited in recent decades for their importance in fundamental science and their applications in biomedical therapeutics, catalysis and as a bottom-up approach to the production of ordered nanostructures. Key [...]

Design of In-situ Electrochemical Cells for XAS Experiments

Katsoudas J.P., Timofeeva E.V., Segre C.U., Illinois Institute of Technology Material Collaborative Access Team, US

The high demand for better performing battery electrodes and fuel cell catalysts has pushed the direction of experimental design for in situ electrochemical (EC) cells towards non invasive experimental techniques such as x-ray absorption spectroscopy [...]

Acid-basic site detection and mapping on solid surfaces at the nanoscale, by Kelvin force microscopy (KFM)

Gouveia R.F., Bernardes J.S., Ducati T.R.D., Galembeck F., University of Campinas, BR

The present work shows, for the first time, that the electric potential pattern of acid and basic solid surfaces is modified under variable relative humidity, as determined by using Kelvin force microscopy (KFM). This allows [...]

Development of a metrological scanning probe microscope as a primary standard for nanoscale dimensional measurement

Babic B., Freund C., Gray M.B., Herrmann J., Hsu M.T.L., Lawn M., McRae T.G., National Measurement Institute Australia, AU

The capability for accurate dimensional measurement at the nanoscale, traceable to the SI meter, is fundamental for the development and effective support of nanoscience and nanotechnology. At the National Measurement Institute Australia (NMIA), the primary [...]
