Viscoelastic Contact Resonance Force Microscopy of Polymers in Liquid

Churnside A.B., Tung R.C., Aziz A., Bryant S., Killgore J.P., NIST, US

Contact resonance force microscopy (CR-FM) is an AFM-based technique for quantitatively determining the nanoscale mechanical properties of materials. In CR-FM, the resonant properties of an AFM cantilever in contact with the surface are interpreted as [...]

3D Nanostructuring and Nanoanalysis of Human Enamel and Dentin Using Focused Ion Beams

Sadighikia S., Sezen M., Sabanci University, TR

This study particularly focuses on three dimensional nanoanalysis of human dentin and enamel samples, using FIB nanostructuring methods such as FIB tomography and preparation of 3D TEM samples. All biological tissues have three dimensional features [...]

Comparison of carbon nanotube data collected using two microscopy methods: dark-field hyperspectral imaging and electron microscopy

Eastlake A.C., Geraci C.L., NIOSH, US

Currently, the National Institute for Occupational Safety and Health (NIOSH) Nanotechnology Research Center uses a modified version of the NIOSH Manual of Analytical Method 7303 (Elements by ICP) and electron microscopy (either scanning or transmission) [...]

Insight into bacteria: magnetosomes chains under photoemission electron and scanning electron microscopes

Keutner C., von Bohlen A., Berges U., Espeter P., Schneider C.M., Westphal C., TU Dortmund University, DE

Magnetotactic bacteria (MTB) are forming magnetosome chains consisting of greigite or iron oxides. In technological, medical, and environmental applications magnetosomes are considered as perspective material. Among all techniques applied to MTB, two providing spatial, chemical, [...]

Nanoscale Materials Characterization

A Novel Application Technique for Polymer Nanofibers in the Construction Industry

Araya A.L., Vargas R.F., Cuevas R., Chaves J.S., Instituto Tecnologico de Costa Rica, CR

During 2008 about 3 billion tons of concrete were produced all over the world, making it the most important industrial product produced in the history of mankind. Therefore, any technological improvement in this product will [...]

Mechanically Durable Superhydrophobic Nanocomposites from Acrylonitrile Butadiene Styrene (ABS)

Milionis A., Yeong Y.H., Loth E., Bayer I.S., University of Virginia, US

We report on the development of nanocomposites based on a combination of ABS with hydrophobically modified fumed silica (HMFS). By tuning the ratio between the two materials we are again able to obtain static water [...]

3D Printered and Plasma Treated Superhydrophobic Mesh Filters for Oil-water Separation

Lee H.J., Lee S., Jo W., Lee H.J., Lee S., Moon M.-W., Korea Institute of Science and Technology, KR

We develop the 3D printed mesh filters with plasma treatment using a radio-frequency plasma-enhanced chemical vapor deposition (rf-PECVD) to control their surface wettability. The nano-sclae hairy structures on the meshes are created by plasma etching [...]

Advanced Coating for Energy Applications

Veedu V., Pollock J., Oceanit, US

Quest for oil and gas has increased in the past few decades and the industry is in a constant change of flux to identify new oil reserves and extraction methods to recover oil and natural [...]

Immobilization of AgZnO photocatalyst in Poly(acrylic acid) matrix and their photocatalytic activity evaluation

Jasso-Salcedo A.B., Meimaroglou D., Camargo M., Hoppe S., Pla F., Escobar-Barrios V.A., IPICYT, MX

The Ag modified Zinc oxide (AgZnO) is a catalyst with increased photocatalytic activity used for degradation of dyes and several organic molecules, in aqueous solution, in contrast to pure ZnO. Nevertheless, its application at pilot [...]
