Argonne Impacts State by State

Argonne’s collaborations in Maryland and across the United States have led to groundbreaking discoveries and development of new technologies that help meet the nation’s needs for sustainable energy, economic prosperity, and security.

Blazing a path to broaden the appeal of electric vehicles (EVs), the U.S. Department of Energy’s (DOE) Office of Energy Efficiency and Renewable Energy has awarded $5 million in funding for a four-year project focused on smart charging programs for electric vehicle charging. Exelon Corporation leads the project along with DOE’s Argonne National Laboratory and other partners. Scientists will test a set of smart charging programs, devices and approaches, quantifying the potential benefits to EV owners and Maryland grid operators.  

Our projects focus on transportation electrification and electric vehicle charging in a broad, multi-disciplinary way,” said Yan (Joann) Zhou, principal analyst and group leader of Vehicle and Energy Technology & Mobility Analysis in Argonne’s Energy Systems division. Researchers will use an Argonne-Exelon copyrighted software tool, Agent-based Transportation Analysis Model (ATEAM), to examine potential smart charger locations and study how smart charging management can aid both EV adoption and charging deployment. 

Since most charging stations currently lack networks that directly communicate between the vehicle and utility, researchers will install 400 Argonne-developed Smart Charge Adapters (a 2017 finalist for an R&D 100 Award) at locations to be determined by their infrastructure modeling. Researchers will also use vehicle telematics and an established network provider to offer smart charge management programs to thousands of customers across several customer classes. 

Maryland, Argonne scientists team up to study nanoparticles in polymers

Polymers — large, chain-like molecules — are everywhere. Some occur naturally in living organisms; for example, proteins and the nucleic acids in DNA are polymers. Other polymers are synthetic: Think nylon, Teflon and epoxy. In recent years, scientists made the groundbreaking discovery that adding nanoparticles to a polymer created a lightweight yet strong material with applications for many industries. However, researchers have yet to fully understand the role nanoparticles play in polymers.  

Scientists at Argonne partnered with researchers from the U.S. Department of Commerce’s National Institute of Standards and Technology (Gaithersburg) and the University of Maryland, College Park (UMD) to study the motion of silica nanoparticles in a polymer melt. Using X-ray photon correlation spectroscopy at Argonne’s Advanced Photon Source (APS), the team dispersed the nanoparticles in polyethylene oxide and was able to follow the motion of the nanoparticles within the polymer melt. The findings promise to change current thinking about how nanoparticles move within and reinforce polymer composites.  

The APS is a DOE Office of Science User Facility. 

Stabilizing single-atom catalysts with shocking heat waves

Catalysts are important; for example, the platinum in a catalytic converter speeds the chemical reaction that changes toxic carbon monoxide to less dangerous carbon dioxide. Single atoms make great catalysts, but they’re unstable and rarely stay unattached for long. How to stabilize them and keep them from clustering? To answer that question, Argonne collaborated with UMD, Johns Hopkins University (Baltimore), the University of Illinois at Chicago and the DOE’s Environmental Molecular Sciences Laboratory (Richland, WA). 

Because the most useful catalytic reactions occur at high temperatures, the team targeted catalysts with shock waves at heats of up to 3,000 kelvins (about 4,900 degrees Fahrenheit). Repeatedly exposing catalysts to such shock waves breaks them into single atoms, enabling them to remain stable for unprecedented lengths of time.  

For this pivotal discovery, scientists used a platinum catalyst and a carbon substrate. As a catalyst, platinum accelerates many important reactions, such as powering fuel cells and converting natural gas to more useful forms. Computer simulations modeling how the system would behave closely matched the actual results obtained during tests at Johns Hopkins and X-ray absorption spectroscopy at Argonne’s APS.
