Electron paramagnetic resonance (EPR) spectroscopy is only sensitive to systems containing unpaired electron spins. This makes EPR an indispensable technique for research into the chemical, biochemical and catalytical reactions where these radicals play a vital role. Another related field of application is in photochemistry, where chemical reactions are initiated by light.
After light absorption, the first step of transformation involves a charge separation process, which create both a negatively charged electron and a positively charged hole. Both of these posses unpaired spins and can be detected, characterized and followed by EPR. Furthermore, open-shell transition metals which are at the center of many catalytic reactions can also be studied in detail by EPR spectroscopy.
Particle accelerators use electric fields to speed up and increase the energy of a beam of particles. These particles are steered and focused with magnetic fields. The Low-Energy Accelerator Facility (LEAF) consists of an electron linear accelerator (LINAC) and a Van de Graaff (VDG) electron accelerator. Originally built in 1969, the LINAC recently underwent a significant upgrade to increase the beam power and energy. Researchers in Argonne’s Nuclear Engineering Division use the LEAF for a wide range of applications. This talented team of radiochemists, chemical and nuclear engineers, health physicists and experienced technicians supports multiple programs on behalf of sponsors such as the U.S. Department of Energy’s (DOE’s) National Nuclear Security Administration, U.S. DOE Office of Science Isotope Program and the Defense Threat Reduction Agency.
The Mechanisms Engineering Test Loop (METL) facility, established in 2010, is an intermediate-scale liquid metal experimental facility that provides purified R-grade sodium to various experimental test vessels to test components that are required to operate in a prototypical advanced reactor environment. Experiments conducted in METL significantly assist the development of advanced reactors.
Targets can be produced by wet chemical methods, molecular deposition, mechanical rolling and pressing. The laboratory is equipped with a split glovebox for handling actinides, a HEPA-filtered hood for working with metal powders, and several chemical fume hoods for working on various processing/production methods.
The Advanced Photon Source (APS) at the U.S. Department of Energy’s Argonne National Laboratory provides ultra-bright, high-energy storage ring-generated x-ray beams for research in almost all scientific disciplines. Today researches have been using the APS to develop the next generation of batteries, improve the durability of 3-D printed alloys, and maximizing the efficiency of chemical processes like electroysis. The knowledge gained from this research is impacting the evolution of combustion engines and microcircuits, aiding in the development of new pharmaceuticals, and pioneering nanotechnologies. The goals of the APS are to:
- Operate a highly reliable third-generation synchrotron x-ray radiation source;
- Foster a productive environment for conducting research;
- Enhance the capabilities available to users of the APS facility;
- Assure the safety of the facility users and staff and the environment;
- Maintain an organization that provides a rewarding environment that fosters professional growth, and;
- Optimize the scientific and technological contribution to the Department of Energy and society from research carried out at the APS.
The APS welcomes industrial users conducting both proprietary and nonproprietary research and considers requests for work ranging from short-term feasibility studies to long-term research projects, either on a stand-alone basis or in collaboration with facility or academic colleagues.
