Composite Interphase

Polymer Composites

Ongoing
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

Polymer Formulations

Completed
Bringing new and optimized formulated products to market requires measurements that will allow rapid assessment of the structure and properties of multicomponent mixtures over large parameter spaces. To this end, we are developing microfluidic "lab on a chip" technologies that enable researchers to
High Impact Ballistic Testing of Polymer Films

Polymer Mechanics

Ongoing
The mechanical behavior for polymers is very sensitive to the deformation rate of the impact test. Thus we are developing and applying several novel measurements that can study the mechanical response of the polymer at different deformation rates and at different material length scales. High-rate

Polymer Membranes

Ongoing
We are developing and applying the following advanced tools to measure the structure, dynamics, and performance of polymer-based membranes and sorbents: Vibrational Spectroscopy We have developed a custom-built tandem quartz crystal microbalance (QCM), which measures total mass uptake of adsorbed

Polymer Property Predictor and Database

Ongoing
We aim to generate the data necessary for polymer informatics by developing information extraction pipelines to automatically extract polymer properties from the literature. We use natural language processing software (ChemDataExtractor) to extract both names of chemical entities and properties

Polymers for Next-Generation Lithography

Completed
We work closely with the semiconductor industry to develop and apply measurements with high-spatial and chemically-specific resolution to elucidate the critical materials properties and process kinetics at nanometer scales that are needed to advance next-generation photolithography, including both

Renewable Polymers

Completed
In this project, use innovative measurements to optimize existing materials synthesis and discover new routes to polymers from renewable feedstocks by providing characterization methods that can describe the mechanisms and of enzymatic catalysis of polymers from renewable feedstocks and synthetic

Structure-Property Relationships for High-Strength Materials

Ongoing
The body-armor community generally bases armor design on empirical models that do not directly relate molecular properties to performance. Aramid, aramid copolymers, and polyethylene fibers are highly oriented, anisotropic fibers that require specialized characterization techniques. In addition

Sub-nanoscale electron microscopy of complex nanostructures

Ongoing
The properties of advance materials are becoming ever more reliant on the ability to manipulate their chemistry and structure at very fine length scales. For example, the relevant feature sizes in state-of-the-art transistors continue to decrease, even as the complexity of the architectures employed

Synchrotron Resonant Scattering and Diffraction

Ongoing
The Resonant Scattering and Diffraction effort seeks to develop measurements that provide spatial correlations in chemical, electronic, and physical structure in advanced materials. Scattering technology is developed as part of the NIST BNL partnership at the National Synchrotron Light Source II in

Synchrotron X-ray Absorbance Spectroscopy

Ongoing
The Absorbance Spectroscopy effort seeks to develop measurements that provide details of the local chemical, electronic, and physical structure in advanced materials. Spectrometer technology is developed as part of the NIST BNL partnership at the National Synchrotron Light Source II in Upton, NY

Synchrotron X-ray Spectroscopic Imaging

Ongoing
Building off technologies and expertise developed in the Synchrotron X-ray Absorption Spectroscopy project, the Spectroscopic Imaging effort seeks to develop measurements that provide spatial mapping of the local chemical, electronic, and physical structure in advanced materials. Technology is
