The mission of the Environmental Molecular Sciences Laboratory (EMSL), a U.S. Department of Energy (DOE) scientific user facility, is to provide integrated experimental and computational capabilities for discovery and technological innovation in the environmental molecular sciences.
Understanding physical, chemical, and biological processes at the molecular and systems levels is crucial for enabling scientific breakthroughs that support the needs of DOE and the nation. These breakthroughs are leading to strategies for making bioenergy sources and carbon biosequestration realities, improved catalysts and materials for industrial applications, tools for managing and predicting the movement of subsurface legacy wastes such as radionuclides and heavy metals, and approaches for mitigating climate change.
Integrating minds and methods under one roof, DOE’s EMSL is breaking new ground by accelerating scientific discovery at the frontier of molecular systems science.
Supported by DOE’s Office of Biological and Environmental Research, EMSL offers users access to more than 60 major experimental and computational systems, including many one-of-a-kind analytical instruments for studying atomic to molecular to larger scale processes, and a supercomputing platform and associated computational chemistry software. In-house scientists help users obtain high-quality and timely results. By co-locating capabilities and expertise, DOE’s EMSL is ideal for research teams interested in integrating theory with experiment and for individual investigators conducting a wide range of studies.
EMSL capabilities allow users to examine the fundamental processes that underlie the complex energy and environmental challenges facing DOE and the nation. For example, users can:
Through multidisciplinary collaborations between users and expert staff, DOE’s EMSL develops and applies one-of-a-kind experimental and computational tools to novel studies of complex systems, advancing the science needed to solve environmental and energy challenges.
Atomic and molecular-scale surface deposition and characterization, including systems for ion and molecular beam and chemical vapor deposition, photoelectron spectroscopy, and Fourier transform infrared spectroscopy.
High-performance computing resources, including Chinook, a 163-teraflop production supercomputer, and NWChem, DOE’s premier computational chemistry software.
Microscopy capabilities, including high-resolution, cryo-, and scanning tunneling electron microscopies; stochastic optical reconstruction; photoemission electron; dual-beam focused ion beam–scanning electron microscopy; field-emission scanning; dual-Raman confocal; and single-molecule fluorescence.
Nuclear magnetic resonance (NMR) spectrometers, including 11 systems, ranging from 300 to 900 MHz, equipped with extreme temperature probes and available for radiological research and for use in high-field liquid-state, solid-state, and microimaging techniques.
Subsurface flow and transport tools, including column, batch, radial, and rectangular flow cells; microfluidics capabilities; and a dual-energy gamma radiation system.
Ultra high-resolution, high-throughput mass spectrometers, including several Fourier transform ion cyclotron resonance (FTICR), linear trap, triple-quadrupole, ion mobility, Orbitrap, and single-particle laser ablation time-of-flight spectrometers, as well as software tools for analyzing “omics” data.
DOE’s EMSL is preparing for the world’s highest-field FTICR mass spectrometer, a NanoSIMS system, and an oxygen plasma–assisted molecular beam epitaxy system. In addition, $60 million of Recovery Act funding is being used to acquire and build NMR spectrometers with unique probe technology, high-throughput mass spectrometers, and leading-edge imaging systems.
To provide a scientific focus for user research and to match appropriate EMSL resources and scientific expertise, EMSL categorizes most user research within three science themes:
Researchers may submit a general proposal to use EMSL capabilities through the EMSL website at any time. DOE’s EMSL supports both open and proprietary research proposals, all of which are externally peer reviewed. In addition to general proposals, EMSL issues an annual Science Theme call and periodic calls for specific types of proposals:
Nearly half of EMSL’s 700 annual users are from academia; the rest are from DOE national laboratories, other federally sponsored labs, and industry.
DOE’s EMSL seeks to attract new, highly qualified users and honor their major contributions through fellowships and awards:
