Vorlage:Infobox laboratory EMSL http://www.emsl.pnnl.gov/emslweb/(pronounced em-zul), or the William R. Wiley Environmental Molecular Sciences Laboratory, is a national scientific user facility located at Pacific Northwest National Laboratory in Richland. Wash. EMSL is funded by the Department of Energy’s Office of Biological and Environmental Research. EMSL provides integrated experimental and computational resources to address the complex environmental molecular science challenges facing DOE and the nation.[1]

EMSL offers the global scientific community a diverse range of capabilities and expertise. Access to EMSL’s capabilities is gained through a peer-reviewed proposal process. If a proposal is accepted and the scientist publishes in the open literature, there typically is no charge for using the EMSL instrumentation and capabilities. EMSL provides a variety of proposal opportunities throughout the year.[2]

Since it opened in 1997, scientists from all 50 states and more than 35 countries have used EMSL’s to support their scientific efforts.

EMSL is a national scientific user facility in Richland, Wash.

Research at EMSL is well aligned with DOE's mission and focused on gaining a more thorough, predictive and system-level understanding of the physics, chemistry and biology governing environmental processes starting at the molecular scale and propagating to larger scales. EMSL’s research focus has been defined into three science themes. [3]

  • Biological Interactions and Dynamics: Developing a quantitative, systems-level understanding of the dynamic network of proteins and molecules that drive cell responses and how groups of different cells interact to give rise to functional cell communities.
  • Geochemistry/Biogeochemistry and Subsurface Science: Studying molecular scale reaction mechanisms at the mineral-water, microbe-mineral, and fluid-fluid interfaces and understanding the effect of these mechanisms on the fate and transport of contaminants.
  • Science of Interfacial Phenomena: Developing an understanding and gaining control of atomic- and molecular-level structure–function relationships at interfaces that enable the optimization of interfacial properties, such as the control of catalytic activity and selectivity.

Capabilities at EMSL

EMSL offers an extensive collection of state-of-the-art capabilities[4] to address scientific challenges relevant to the DOE and the nation. EMSL encourages researchers from around the world its unique capabilities in combination with each other with an emphasis on integrating computational and experimental instruments.

EMSL’s capabilities include:

  • Subsurface Flow and Transport – allows the study of chemical reactions in heterogeneous natural materials with an emphasis on soil and subsurface systems. EMSL's approach to subsurface flow and transport studies is holistic, integrating flow cells, analytical tools, tomographic imaging and predictive modeling capabilities to study subsurface phenomena.

EMSL continues to enhance its capabilities and the scientific impact of its users' research with new facilities – including a new Quiet Wing[5] that opened in early 2012 and a Radiochemistry Annex[6] opening to the global user community in spring 2014. (Selected new radiological capabilities are available in limited capacity.)

  • Quiet Wing - EMSL’s new Quiet Wing is one of the most advanced quiet laboratories in the world. It was designed to help accelerate critical science by allowing state-of-the-art ultra-sensitive microscopy equipment to operate at optimal resolution. The wing’s design eliminates or reduces to a minimum the vibrations, acoustics and electromagnetics that can interfere with the resolution of ultra-sensitive scientific instrumentation. The facility and its unique collection of microscopy and scanning instruments will benefit a wide range of research areas, including catalysis, fuel cell/energy storage, subsurface science and health-related biology.
  • Radiochemistry Annex - EMSL’s new Radiochemistry Annex offers an expansion of capabilities for analysis of radiological samples. It gives users access to a full suite of state-of-the-art instrumentation co-located in one facility that is unique in the United States, and one of just a few such facilities worldwide. The Radiochemistry Annex instrument suite is optimal for the study of contaminated environmental materials, examination of radionuclide speciation and detection of chemical signatures.

EMSL staff and scientific consultants are experts in chemical, physical, biological and computational sciences. They have received numerous awards, been named to society fellowships, have received patents and publish in scientific journals.[1] Since 2009, EMSL staff members have received nearly two dozen awards and honors.[7] In fiscal year 2010, EMSL staff and user research appeared in more than 350 articles, including many in prestigious journals, such as Science, Nature, Proceedings of the National Academy of Science and Journal of the American Chemical Society.[7]

Staff collaborates with EMSL’s users to help discover solutions to the nation's energy, environmental, national security, and human health problems. Staff members also develop new tools and tailor existing instruments to meet the evolving needs of the lab’s scientific users.

History

[4][7]

The Beginnings (1986–1997)

The idea that would become EMSL began in 1986 with a National Academy of Sciences report entitled Opportunities in Chemistry. The report identified scientific challenges relating to energy and the environment that required fundamental research to achieve a solution. Then director of PNNL William R. Wiley and lab senior managers met to discuss the report and how PNNL could respond to the nation’s scientific challenges that were critically dependent on fundamental advances in chemistry. Their recommendations would become EMSL, a center with advanced instrumentation for the study of molecular-level chemistry.

Wiley envisioned a facility where the research was conducted in an integrated and collaborative manner. “Problems don’t come in small, unique, compartmentalized packages. We must recognize the interrelationships,” said Wiley.

Ohio-based Battelle Memorial Institute, which operates PNNL for the U.S. Department of Energy, approved $8.5 million in funding over four years to establish the facility; develop research programs; and obtain the equipment, facilities, scientists and staff to support these programs.

The DOE authorized PNNL to proceed in October 1993, and PNNL began construction of the facility in July 1994. The facility was dedicated on October 16, 1996, in honor of Wiley, who died three months earlier. Construction was completed in August 1997. Then-DOE Secretary Hazel O'Leary delivered the dedication speech and Wiley’s wife, Gus, cut the ribbon. EMSL opened Oct. 1, 1997, for full operation as DOE’s newest national scientific user facility.

The Early Years (1997–2001)

During its first five years, EMSL operations successfully focused on building capabilities, recruiting scientific leadership and attracting users. The scientific focus then expanded to include biology, particularly the study of naturally occurring microbes for environmental cleanup, alternative energy, and carbon dioxide reduction in the atmosphere – critical challenges addressed by DOE.

EMSL’s early user program focused on single investigator studies – particularly those Wiley championed that crossed disciplinary boundaries – and quickly reached more than 1,000 users per year, representing every state and several foreign countries.

A Maturing Program (2001–2009)

After the startup years, EMSL moved into a period of significant scientific impact in broad areas of science. Its robust user program was mostly based on the single principle investigator user mode. Although highly productive, EMSL started to focus its resources toward more specific scientific targets to increase the lab’s impact on scientific areas that address issues of importance to DOE and the nation.

The first of these efforts were two Grand Challenges. These challenges were team-based, multi-investigator research efforts targeted on two key challenges related to DOE missions: 1) a biogeochemistry question concerning the fundamental interaction between microbes and minerals, and 2) a study addressing the structure and function of proteins in the cell membrane. These multi-year studies proved the added value of multi-investigator projects with teams focused on a specific challenge.

Dr. Willam R. Wiley (1931–1996) was a distinguished Battelle scientist and one of the driving forces behind the creation of EMSL. The facility was named in his honor.

EMSL’s management further defined the lab’s research focus by establishing science themes, high priority research topics. Finalized in 2006 as four themes and later focused to three, these Science Themes define and direct the development of key capabilities and user projects to provide the greatest alignment with and impact to DOE’s mission. EMSL’s current science themes are:

In January 2007, EMSL celebrated its first permanent expansion: a nearly 4,000-square-foot raised floor within its high-performance computing operations center to accommodate a more powerful supercomputer. In April 2008, EMSL dedicated a new office pod to distinguished user J. Mike White that houses nearly 100 staff and users. At the same time, EMSL management began pursuing plans for a Radiochemistry Annex and a Quiet Wing.

Building for the Future (2009 to Present)

In 2009, DOE announced a $60 million investment in new capabilities for EMSL from the American Recovery and Reinvestment Act, or ARRA. EMSL used the funds to upgrade some existing capabilities, as well as developing and deploying totally new systems and capabilities to maintain the lab’s position as a state-of-the-art user facility.

At this same time, EMSL directed capital funds toward construction of the $8 million Quiet Wing to house up to eight state-of-the-art ultra-sensitive microscopy instruments. The Quiet Wing opened in early 2012. Additionally, EMSL moved forward with plans for a radiological chemistry capability with a Radiochemistry Annex, slated to open in 2014.

With world-leading capabilities and a robust science foundation, EMSL continues to realize Wiley’s vision of the science impact that can be achieved through interdisciplinary research that crosses theory and experiment. EMSL fosters a team-based approach to leverage data and tools in new ways for accelerated and heightened science impact.
