Atmospheric aerosol particles often have compositions and shapes that cannot be described as a single material phase within a simplified geometric form such as
We use autonomous experimentation to elucidate the role of composition, processing, and microstructure on the aqueous corrosion of complex metal alloys. To do
We are developing novel machine learning algorithms and incorporating them into closed-loop autonomous systems to accelerate knowledge capture in the lab and in
Founded in 2019, this program was motivated by the rapid decriminalization of recreational and medical cannabis by state governments. This has led to extensive
It is well known that the physical properties of a fluid can change profoundly, and often non-trivially, when placed in a confined environment. Only for the
In classical molecular simulations, electrostatic contributions to the potential energy are typically accounted for by assigning partial charges to some or all
NMR spectroscopy is routinely used to analyze chemical mixtures in the liquid phase. It is far less common for these techniques to be applied to vapor-phase
Many polymeric fluids, including biotherapeutics and fuels, can have unusual physical behavior in solutions, and many applications require detailed knowledge of
By using machine learning approaches, we seek to elucidate underlying universal characteristics of fluids and fluid mixtures that enable property prediction
NIST’s Material Measurement Laboratory and Communications Technology Laboratory are developing a new spectroscopy for intermolecular interactions. The team is
This project develops and applies metrologies and standards for characterizing microstructure and dynamics in advanced functional materials of technological
Nanocalorimetry provides a capability to measure the thermal properties of very small samples and at very fast rates. Materials and interfaces of interest
Overview Capture of carbon dioxide from the air (direct air capture; DAC) combined with energy efficiency and carbon capture, utilization and storage (CCUS)
The NIST Chemistry WebBook is a site on the Internet ( http://webbook.nist.gov/) that provides convenient access to a variety of physical and chemical property
NIST provides data resources related to adsorption of both gases and liquids on solid adsorbents through the NIST Data Resources for Adsorption Science and
The ocean is a driver for global climate which absorbs approximately 25 % of CO 2 emissions. This excess of CO 2 flowing into the ocean leads to changes in the
NIST Standard Reference Database 173 Last Update to Data Content: August 2023 DOI: https://doi.org/10.18434/T4M88Q The Standard Reference Simulation Website is
Our goal is to develop combinatorial and high-throughput measurement approaches for rapid characterization of the structure and phase behavior of multicomponent
Energy is one of the most critical problems facing the United States, with technical, economic, and public policy aspects. Our group develops state-of-the-art
Observing and measuring the dynamic changes that take place at the nanometer scale during the synthesis and operation of active nanostructures is vital for
Theory and simulation are used to advance our understanding of pure and multicomponent fluids confined in tight spaces, such as the pores of a zeolite, metal
We develop and deploy portable vapor sampling instruments to collect detailed chemical information in the field, in sampling situations where the laboratory is
We develop and evaluate dynamic headspace sampling methods to capture and concentrate vapors from single components (solid or liquid) to determine vapor
