µMAG: Micromagnetic Modeling Activity Group

Micromagnetics concerns the patterns of magnetization that arise in materials on the scale of nanometers. Understanding these structures is key to technologies...

3D Elemental Mapping of Cells Using Electron and Ion Beams

Although it is the most commonly used technique for the chemical analysis of cells, mass spectrometry of cell lysate can only provide bulk analysis of...

3D Strain Mapping: Transmission Bragg Edge Strain Tensor Tomography (TBESTT)

Imagine an MRI or CT technique that can peer inside structural materials (e.g., steels) and visualize the strain experienced by structures as they support...

A Comparison of WD-EPMA Heterogeneity Testing Procedures

The heterogeneity of the four elements in a TiAl(NbW) SRM 2061 alloy were determined from five specimens with WD-EPMA (wavelength dispersive – electron probe...

Ab initio theoretical modeling for predicting structure and properties in advanced materials

We develop first-principles-based methods for prediction of atomic arrangements and properties in advanced materials and develop tools for the prediction and...

Additive Manufacturing Fatigue and Fracture

This project aims to enable use of metal additive manufacturing (AM) in fatigue and fracture critical applications via two main thrusts: Investigation of...

Advanced Ambient Mass Spectrometry, Secondary Ion Mass Spectrometry and Ion Mobility Spectrometry

Advanced Composites Pilot for the Materials Genome Initiative

The development of new materials for diverse applications relating to the development of new energy sources, more efficient homes, autos, and aircraft, and the...

Advanced Linear and Nonlinear Optical Properties of Materials

High-accuracy linear and nonlinear optical properties of materials used for leading-edge optical technologies are measured and characterized to enable these...

Advanced Materials Metrology

In this project we measure the fundamental electrical properties of materials from bulk to nanoscale from 1 MHz to 0.3 THz. Understanding the interaction of...

Cross section of a SAC solder joint in a BGA, with sketches of potential micro specimens

Advanced Mechanical Characterization of Mesoscale Materials

Conventional mechanical test methods face limitations when specimens are smaller than a few millimeters in length, but information at this scale is needed for...

Amplifiers

To process quantum information it is important to have amplifiers with wide bandwidth, high dynamic range, and low noise.

Analysis of 3D Elemental Mapping Artifacts in Biological Specimens using Monte Carlo Simulation

We performed Monte Carlo simulation to demonstrate the feasibility of using the focused ion beam based X-ray microanalysis technique (FIB-EDS) for the 3D...

Analysis of Copper Incorporation Into Zinc Oxide Nanowires

ZnO nanowires (NWs) are grown on bulk copper by chemical vapor deposition. Photoluminescence (PL) microscopy revealed band gap emission at 380 nm and a more...
