Doctoral student Rebecca Brenneis' work on removing methane from air using a copper zeolite catalyst is featured in an article in The Wall Street Journal, titled "Cat Litter Could Be Antidote for Climate Change, Researchers Say". Briefly speaking, the catalyst material is made by soaking an odor-eating clay (zeolite) used in cat boxes in a copper solution. The material snatches methane from passing air and turns it into carbon dioxide, a much less harmful greenhouse gas. The Energy Department gave the researchers $2 million to design devices with the material that can be attached to vents at coal mines and dairy barns, which are big methane emitters. Basically, the idea is to alter the chemistry of emissions before they hit the open air, like a catalytic converter on a car. In the end, the work has the potential to greatly reduce the amount of methane in the atmosphere and slow warming temperatures on the planet. It could also create another possible application for zeolite, a clay used to clean up some of humankind’s nastiest messes.

Boya, Nicholas, Glen, Yunpo, Rebecca, Austin, and Andrew's work published on Environmental Science: Processes & Impacts

Boya, Nicholas, Glen, Yunpo, Rebecca, Austin, and Andrew's work published on Environmental Science: Processes & Impacts, titled "Groundwaters in Northeastern Pennsylvania near intense hydraulic fracturing activities exhibit few organic chemical impacts". This work illustrates that a large sampling of groundwater wells in Northeastern Pennsylvania have not been substantially contaminated with hydrophobic organic contaminants spanning a spectrum of volatilities (volatile organic, gasoline-, or diesel-range organic compounds) even after a decade of intense hydraulic fracturing activity. The reasons for this can include the relatively protective nature of groundwater flow in the area, long transport times of sorption-retarded chemicals, and a lack of systematic chemical releases from oil and gas well operations. Nevertheless, accidental chemical releases are commonly documented, albeit with limited specificity.

Congratulations to Boya, Nicholas, Glen, Yunpo, Rebecca, Austin, Andrew, and Desiree!!

Rebecca's work on methane oxidation using earth-abundant catalyst featured in MIT NEWS!

Methane is a far more potent greenhouse gas than carbon dioxide, and it has a pronounced effect within first two decades of its presence in the atmosphere. In the recent international climate negotiations in Glasgow, abatement of methane emissions was identified as a major priority in attempts to curb global climate change quickly. Now, the Plata Lab has come up with a promising approach to controlling methane emissions and removing it from the air, using an inexpensive and abundant type of clay called zeolite.

Boya, Yunpo, Austin, Nicolette, Lukas, and Rebecca's collaboration work published on Environmental Science and Technology

Boya, Yunpo, Austin, Nicolette, Lukas, and Rebecca's collaboration work published on Environmental Science and Technology, titled "Assessing Unconventional Oil and Gas Exposure in the Appalachian Basin: Comparison of Exposure Surrogates and Residential Drinking Water Measurements". Health studies report associations between metrics of residential proximity to unconventional oil and gas (UOG) development and adverse health endpoints. We investigated whether exposure through household groundwater is captured by existing metrics and a newly developed metric incorporating groundwater flow paths. The results showed that correlations between inorganic chemicals and metrics were limited (all |ρ| ≤ 0.28). This result may indicate that UOG-related water contamination occurs rarely/episodically, more complex metrics may be needed to capture drinking water exposure, and/or spatial metrics in health studies may better reflect exposure to other stressors.

Congratulations to Boya, Yunpo, Austin, Nicolette, Lukas, Rebecca, and Desiree!!

Rebecca, Eric, and Wenbo's work published on ACS Environmental Au

Rebecca, Eric, and Wenbo's work published on ACS Environmental Au, titled "Atmospheric-and Low-Level Methane Abatement via an Earth-Abundant Catalyst". Climate action scenarios that limit changes in global temperature to less than 1.5 °C require methane controls, yet there are no abatement technologies effective for the treatment of low-level methane. This work describes the use of a biomimetic copper zeolite capable of converting atmospheric- and low-level methane at relatively low temperatures (e.g., 200–300 °C) in simulated air. Depending on the duty cycle, 40%, over 60%, or complete conversion could be achieved. Improved performance at longer activation was attributed to active site evolution, as determined by X-ray diffraction. The conversion rate increased over a range of methane concentrations (0.00019–2%), indicating the potential to abate methane from any sub-flammable stream. Finally, the uncompromised catalyst turnover for 300 h in simulated air illustrates the promise of using low-cost, earth-abundant materials to mitigate methane and slow the pace of climate change.

Congratulations to Rebecca, Eric, Wenbo, and Desiree!!

Yunpo, Nathalie, Rebecca, and Boya's work published on Environmental Science and Technology

Yunpo, Nathalie, Rebecca, and Boya's Work was published on Environmental Science and Technology, titled "Groundwater Methane in Northeastern Pennsylvania Attributable to Thermogenic Sources and Hydrogeomorphologic Migration Pathways". The objectives of this study were to understand the sources and migration pathways of groundwater-dissolved methane in NE PA, evaluate the potential impacts of UOG development on the groundwater methane level, and move toward better knowledge of the environmental, safety, and climatic impacts of shale gas extraction. Our analysis suggested that the high-concentration groundwater methane could have originated from shallow thermogenic methane that migrated upward into groundwater aquifers with Appalachian Basin brine. The analysis was also extended to constrain the potential contributions of UOG development to groundwater methane emissions over gas-rich shale formations.

Congratulations to Yunpo, Nathalie, Rebecca, Boya, and Desiree!!

Andrew and Brian's Collaboration Work Published On Combustion and Flame

Andrew and Brian's collaboration work with Prof. Gomez Group at Yale University was published on Combustion and Flame, titled "Small Aromatic Hydrocarbons Control the Onset of Soot Nucleation". The gas-to-particle transition is a critical and hitherto poorly understood aspect in carbonaceous soot particle formation. Polycyclic Aromatic Hydrocarbons (PAHs) are key precursors of the solid phase, but their role has not been assessed quantitatively probably because, even if analytical techniques to quantify them are well developed, the challenge to adapt them to flame environments are longstanding. This work presents simultaneous measurements of forty-eight gaseous species through gas capillary-sampling followed by chemical analysis and of particle properties by optical techniques. The principal finding is that only one- and two-ring aromatic compounds can account for soot nucleation, and thus provide the rate-limiting step in the reactions leading to soot.

Congratulations to Andrew, Brian, and Desiree!!

Yunpo and Boya's Collaboration Work Published On Water Resources Research

Yunpo and Boya's collaboration work with Prof. Saiers Group at Yale University was published on Water Resources Research, titled "Evaluating Domestic Well Vulnerability to Contamination From Unconventional Oil and Gas Development Sites". The rapid expansion of unconventional oil and gas development (UD), made possible by horizontal drilling and hydraulic fracturing, has triggered concerns over groundwater contamination and public health risks. To improve our understanding of the risks posed by UD, this work develops a physically based, spatially explicit framework for evaluating groundwater well vulnerability to aqueous phase contaminants released from surface spills and leaks at UD well pad locations.
