Advanced Microscopy for Trace and Bulk Particle Characterization

Ongoing
The goal of this project is to help develop innovative metrologies and measurement protocols for micro/nano-scale analysis of particles. In this project, state-of-the-art optical and electron-based microscopy are used to conduct research for quantitative and qualitative analysis of chemical

Climate Science

Ongoing
This program encompasses multifaceted efforts to advance the metrology of climate science. Projects include: development of ultra-high accuracy optical standards and technologies to determine greenhouse gases (GHGs) concentrations, atmospheric lifetimes, and aerosol radiative forcing development of

Fluid Phase Nuclear Magnetic Resonance (NMR) Spectroscopy

Ongoing
In-situ vapor-liquid equilibrium (VLE). We are applying vapor-phase NMR to measure VLE in-situ . We are currently applying this methodology to industrially important systems such as refrigerants and natural gas. The most widely used refrigerants have high global warming potential. Drop-in
