Comparative HRTEM Examination of Carbon Black and Soot Structures

Spry J.M., Compton S.P., MVA Scientific Consultants, US

Soot is a major source of airborne particulate and typically contains primary particles which are less than one micrometer in diameter. Soot particles form as an undesired combustion by-product originating from a variety of different [...]

Quantitative Analysis of Oxidation State in Cerium Oxide Nanomaterials

Sims C.M., Maier R.A., Johnston-Peck A.C., Gorham J.M., Hackley V.A., Nelson B.C., National Institute of Standards and Technology, US

Of the many engineered nanomaterials being incorporated into our society, cerium oxide (ceria, CeO2-x) based nanomaterials (NMs) are receiving increased attention due to their unique chemical properties and vast number of current and potential applications [...]

SEM Characterization of Adipose Tissue Structure

Brimiene V., Skaudzius R., Misevicius M., Brimas E., Brimas G., Brimas E., Brimas G., Kareiva A., Vilnius University, LT

In this work the scanning electron microscopy (SEM) was used for the characterization of adipose tissue samples taken from volunteer obese patients. The adipose tissue was taken from 3 layers of adipose tissue (subcutaneous, preperitoneal [...]

In situ TEM/STEM of the Coarsening of Nanoporous Gold

El-Zoka A.A., Howe J., Newman R.C., Perovic D., University of Toronto, CA

Nanoporous gold (NPG) is usually fabricated by the selective electrolytic dissolution (dealloying) of Ag from a binary Ag-Au alloy, or sometimes from a ternary alloy such as Ag- Au-Pt. The resulting ligament-pore structure is bicontinuous [...]

Learning the Physics and Chemistry of Surfaces via Machine Vision and Deep Data Analysis

Ziatdinov M., Maksov A., Kalinin S.V., Oak Ridge National Laboratory, US

The last decade has witnessed an enormous increase in the size and quality of datasets produced by microscopic and spectroscopic experimental techniques. Particularly, the recent advances in scanning transmission electron and scanning probe microscopies have [...]

G-Mode KPFM: Bringing Kelvin probe force microscopy into the information age

Collins L., Kalinin S., Jesse S., Oak Ridge National Laboratory, US

Fundamental mechanisms of energy storage, corrosion, sensing, and multiple biological functionalities are directly coupled to electrical processes and ionic dynamics at both the solid-gas and solid-liquid interfaces. In many cases, these processes are spatially inhomogeneous [...]

Applications of Silicon Nanophotonics: Space-division Multiplexing and Integrated Spectroscopy

Grieco A., Hong B., Porter G., Fainman Y., University of California San Diego, US

Data center needs are evolving as more advanced optical transmission techniques are deployed. This presentation discusses recent technological developments pertaining to the scalability and characterization of the network fabric: space-division multiplexing on a chip, and [...]

Application of Angular Method to Correct Channel Spacing Between AWG Demultiplexed Channels

Seyringer D., Vorarlberg University of Applied Sciences, AT

Arrayed Waveguide Gratings (AWGs) offer an attractive DWDM solution because they are a very compact way to provide for higher channel count solutions, have good performance characteristics, and can be more cost effective per channel [...]

Coupled surface plasmon resonance on rotated sinusoidal gratings at different azimuthal orientations

Csete M., Szalai A., Tóth E., Somogyi A., Balázs J., Szabó G., University of Szeged, HU

Theoretical study was performed on rotated grating coupling phenomenon on multilayers comprising 416 nm periodic sinusoidal polymer gratings with 35 nm modulation amplitude aligned on a bimetal film made of gold and silver layers. The [...]
