Towards Medical Diagnostics Using Hyperspectral X-ray Scatter

Greenwood C., Rogers K., Wilson M., Lyburn I., Evans P, Davies G., Cranfield University, UK

This pilot study builds from a recent international, programme that showed, for the first time, the clinical value of new biomarkers to predict fracture risk in osteoporotic patients. The research indicated several potential, high impact [...]

Probing Nanoscale Composites, Interfaces, and Damage Gradients with In-Situ and Ex-Situ Multiscale Mechanical Methodologies

Mara N.A., Los Alamos National Laboratory, US

This presentation reports on recent findings within the Center for Integrated Nanotechnologies that determine the effects of interfacial structures and damage gradients on mechanical response at length scales varying from nanometers to millimeters. Three focus [...]

FibriPy: a software environment for fiber analysis from 3D micro-computed tomography data

Perciano T., Ushizima D., Krishnan H., Sethian J., Lawrence Berkeley National Laboratory, US

Materials characterization using X-ray imaging has enabled development of advanced composites that will open up new opportunities to improve manufacturing. In order to deploy reinforced materials, such as ceramic matrix composites (CMC), several structures must [...]

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 [...]
