Research news

Lockdown drove pollution changes between – even within – cities

Researchers from Washington University in St. Louis developed a method using satellite measurements that allowed them to determine levels of nitrogen dioxide — NO2 — on a scale never before accessible — even in areas where there are no monitoring capabilities on the ground. NO2 is a key contributor to the smog associated with bad traffic or areas of intense industry.

Developed in the lab of Randall Martin, the Raymond R. Tucker Distinguished Professor in the Department of Energy, Environmental & Chemical Engineering, the method allows researchers to infer levels of NO2 in regions as small as a neighborhood.

When they used it to compare levels of NO2 before and during COVID-19-related lockdowns across the globe, they found that, although there was a significant decrease in NO2 worldwide in areas under lockdown, there were also striking discrepancies on smaller scales.

The results were published Jan. 19 in the journal Nature.

NSF grant to help Zhang lab build better muscle with synthetic biology

Fuzhong Zhang, professor of energy, environmental and chemical engineering, has developed a synthetic biology platform to produce muscle fibers that are strong, tough and can absorb energy in ways very similar to the real thing. His research team went on to explore genetic changes that may lead to improved material performance.

The National Science Foundation (NSF) has awarded Washington University in St. Louis’ Zhang lab a $458,490 grant to continue this line of research. His team can now take a closer look at the muscle protein titin to understand what genetic changes to titin are associated with particular material traits.

“We’d like to use our synthetic biology platform as a tool to understand how synthetic muscle fiber works and make better materials,” Zhang said. His team also will use their tools to examine muscle fibers from longextinct animals.

Separator key when it comes to ‘stable’ vs. ‘safe’ battery

Research from the lab of Peng Bai, assistant professor of energy, envi ronmental & chemical engineering, recently revealed the formula for building a perfectly stable sodium electrode.

The team has now discovered the formula for a perfectly stable and safe electrode.

The research was published in January 2022 in the journal Advanced Energy Materials.

Stability in an electrode is key to a well-performing battery. Instability is caused by irregular distribution of metal ions as they move from the cathode to the anode. The more uniformly the ions move, the smoother the outgrowth of metal deposits. This results in a longerlasting battery and, importantly, a battery that is less likely to short and create a hazardous situation.

“Does absolute stability guarantee absolute safety?” Bai asked. It does not, especially during the fast charging. Bai and Bingyuan Ma, a postgraduate research associate, determined why.

The short answer: A critical component that has been left out in laboratory experiments is more important than previously thought. A perfectly safe battery that can undergo fast recharging requires cooperation from the separator.

Mitigating environmental impact of herbicide

To learn more about how the different chemical agents interact in herbicide formulations, a team of researchers is developing a frame work to understand how the pieces come together, said Kimberly M. Parker, assistant professor. Her col laborators in this work are Stephen M. Sharkey, a fourth-year doctoral student in Parker’s lab, and Brent J. Williams, associate professor . Their outlook was published in Environ mental Science & Technology Nov. 23, 2021.

In 2020, about 90% of all corn, cotton and soybeans planted in the United States were genetically modified to tolerate one or more herbicides, such as glyphosate, dicamba or 2,4-dichlorophenoxy acetic acid (2,4-D). As a result, the associated herbicides for the tolerant crops have typically seen increased use, Sharkey found.

“To address these challenges posed by herbicide drift, continued progress is needed to improve practices that prevent drift, including the design of chemical formations and to understand the impact of herbicides after they enter the atmosphere,” Parker said. “By defining factors that contribute to herbicide drift and characterizing the atmospheric processes that influence its impact, we may develop new solutions to prevent it.”

Selenium removal from industrial wastewater focus of new research

Daniel E. Giammar, the Walter E. Browne Professor of Environmental Engineering, will lead the team on the new research with $1.25 million in total funding. The project is supported by the U.S. Department of Energy and through matching funds. The prestigious award is part of $17.7 million the DOE awarded to 16 projects nationwide to bolster development of energy-efficient water-treatment technologies through the National Alliance for Water Innovation, led by Lawrence Berkeley National Laboratory. Emerging technologies in selenium removal have focused on using electrocoagulation, a method that electrochemically introduces a metal ion, such as ferrous iron, to water to ultimately remove contaminants from wastewater in a few different ways: the release of ferrous iron from the anode introduces a reactive species that can remove dissolved selenium while reactions on the cathode may also be involved in selenium removal. Over three years, Giammar and his collaborators plan to advance the use of iron electrocoagulation to remove selenium from water by tailoring the generation of solid particles to have targeted adsorption and reduction properties.

Student organization brings water education to elementary school students

Students in the Department of Energy, Environmental & Chemical Engineering collaborated with the School District of University City and St. Louis Aquarium Founda tion to provide fifth-grade students with a hands-on water education program.

The collaboration was led by Zhen (Jason) He, professor of energy, environmental & chemical engineering and faculty adviser of the Environmental Engineering Students Association (EnvESA).

“If we want to attract more students, especially those from underrepresented groups, to STEM fields, we must start the process earlier,” He said. “This type of outreach can stimulate those students’ interest in STEM and encourage them to further explore the subjects.”

EnvESA members taught more than 200 fifth-grade students at four district elementary schools. As part of the program’s curriculum, students learned about the water cycle and wastewater treatment processes and participated in a activity in which they treated wastewater using different filtering materials.

“Our lessons were geared toward exposing students to water and wastewater treatment,” said Matthew Ferby, a doctoral student in the Department of Energy, Environmental & Chemical Engineering and president of EnvESA. “We also highlighted teamwork and science communication.”
