The agencies are funding 20 projects to be conducted across 24 institutions through the Disaster Resilience Research Grant (DRRG) program, which they manage
Researchers at the National Institute of Standards and Technology (NIST) and Columbia Engineering have discovered a new method to improve the toughness of
To quantify the impact of mechanical degradation on ballistic fibers, NIST developed a novel device for controlled folding of yarns and woven fabrics. In addition, we developed test protocols that employ single fibers to assess the effect of folding using a recently developed modified single fiber
Measurements of interphase properties are extremely challenging, and their effects on macroscopic properties and performance of composites are poorly quantified. The objectives of this project fall into the following four research thrusts: Fluorescence Based Probes to Sense Damage and Water in
The behavior and performance of nanostructured materials and devices are governed by the chemistry and structure of their surfaces and interfaces. However, chemistry-structure-performance relationships in these systems are complex, so hundreds of experiments can be necessary to determine optimal
Project Goal: To develop magnetic resonance, x-ray absorption, electron diffraction, and electrical conductivity measurements to better characterize dilute concentrations of point defects in oxide materials and effectively correlate electro-mechanical properties to measured defect chemistry. Oxide

A suite of phase separated dynamic covalent networks based on highly tunable dynamic benzalcyanoacetate (BCA) thia-Michael acceptors are investigated. In situ
CLIP is an analysis program for fluorescence lifetime images. It provides the user with the ability to fit or calculate the phasor plots for lifetime decays
Description High-throughput (combinatorial) metrologies have evolved as a useful approach to rapidly determine the composition-structure-property relationships
Positron annihilation lifetime spectroscopy uses positrons to probe material defects/voids/free volume at the sub-nm scale. The general working principle is
Thermogravimetric Analysis, or TGA, is a classic thermoanalytical measurement performed on many different types of materials. In our laboratory, it is used for
Differential Scanning Calorimetry, or DSC, is a classic thermoanalytical measurement performed on many different types of materials. In our laboratory, it is
