Explosives Decomposition Chemistry

Completed
Intended Impact Computational modeling and simulation will help in the invention of new explosives, the design of compounded mixtures of existing materials, and the engineering of delivered systems such as military ordnance. Objective Detailed chemistry is a necessary part of computational

Far-infrared Spectroscopy of Biomolecules (Archived)

Completed
We employ novel complimentary measurement and theoretical techniques to explore the low frequency intramolecular dynamics of model biological molecules including amino acids, short peptides with constrained structures, proteins with well-defined tertiary structures and DNAs. Our current efforts

Free Energy and Advanced Sampling Simulation Toolkit (FEASST)

Ongoing
Intended Impact While flat-histogram Monte Carlo simulations have been shown to be a promising method for the direct calculation of complex fluid phase behavior with a variety of applications, most open-source Monte Carlo simulation packages do not support this method. We have therefore made FEASST

Machine Learning Fluid Equations of State

Ongoing
Understanding the thermodynamic properties of fluids and fluid mixtures is of central importance in many fields of science and engineering ranging from medicine to consumer products. The nature of the particles in a fluid can vary greatly depending on the type of interactions present, e.g., dipole

Machine Learning to Predict Multicomponent Colloidal Crystals

Ongoing
There is a direct link between a material’s macroscopic properties and its microscopic structure, which makes rational bottom-up self-assembly a powerful tool for engineering properties of materials. In general, colloids are facile material building blocks whose shape, charge, and surface

Macromolecular Architectures

Ongoing
This project’s purpose is to synthesize and characterize model thermoplastics, thermoplastic elastomers (TPE), and mixed resins with systematic variation of polymer sequence, chemistry, and architectures to generate libraries of quantitative structure-property relationships validated by multiple

Measuring Intermolecular Interactions with Electro-Acoustic Spectroscopy

Ongoing
We have a number of opportunities to collaborate with us. See below for details. What does this project aim to do for the chemical industry? Many industrial processes depend on the intermolecular environment- the solvents and ions that surround a molecule. These interactions impact separations

NCNR DAC and CCUS efforts

Ongoing
Objectives To advance US competitiveness in Direct Air Capture (DAC) and Carbon Capture, Usage, and Sequestration (CCUS) Use advanced neutron scattering techniques to understand the adsorption process for the most promising materials for adsorption-based carbon capture and provide avenues to

NIST Standard Reference Simulation Website

Ongoing
Molecular simulations, in particular Monte Carlo Molecular Simulation and Molecular Dynamics Simulation, are methods for computing the properties of some kind of system, for which the intermolecular interactions are specified via mathematical relationships derived from statistical mechanics. Since

Standards Development to Ensure Reliable Breath Analysis in the Field

Ongoing
Numerous volatile organic compounds (VOCs) have been identified in human breath. These compounds can be produced by the body or by organisms in the body (e.g., bacteria or viruses) and provide a non-invasive window into human health. Inexpensive point-of-care devices are being developed to diagnose

Theoretical Mass Spectrometry

Ongoing
No Description Intended Impact Unknown compounds will be identified more reliably. Quality control for the NIST Mass Spectrometry Database will be enhanced. Goals Develop software tools for predicting microcanonical branching fractions automatically. This is currently too laborious and too technical
