An Analysis of Costs and Health Co-Benefits for a U.S. Power Plant Carbon Standard
(Public Library of Science, 2016)Reducing carbon dioxide (CO2) emissions from power plants can have important “co-benefits” for public health by reducing emissions of air pollutants. Here, we examine the costs and health co-benefits, in monetary terms, ... -
Extremely Stable Anthraquinone Negolytes Synthesized from Common Precursors
(Elsevier BV, 2020-06)Synthetic cost and long-term stability remain two of the most challenging barriers for the utilization of redox-active organic molecules in redox flow batteries for grid scale energy storage. Starting from potentially ... -
Formaldehyde (HCHO) As a Hazardous Air Pollutant: Mapping Surface Air Concentrations from Satellite and Inferring Cancer Risks in the United States
(American Chemical Society (ACS), 2017-05-05)Formaldehyde (HCHO) is the most important carcinogen in outdoor air among the 187 hazardous air pollutants (HAPs) identified by the U.S. Environmental Protection Agency (EPA), not including ozone and particulate matter. ... -
Functioning Water‐insoluble Ferrocenes for Aqueous Organic Flow Battery via Host-Guest Inclusion
(Wiley, 2020-12-09)Ferrocene (Fc) is one of the very limited organic catholyte options for aqueous organic flow batteries (AOFBs), a potential electrochemical energy storage solution to the intermittency of renewable electricity. Commercially ... -
In situ Electrosynthesis of Anthraquinone Electrolytes in Aqueous Flow Batteries
(Royal Society of Chemistry (RSC), 2020-09-02)We demonstrate the electrochemical oxidation of an anthracene derivative to a redox-active anthraquinone at room temperature in a flow cell without the use of hazardous oxidants or noble metal catalysts. The anthraquinone, ... -
A Long-Lifetime All-Organic Aqueous Flow Battery Utilizing TMAP-TEMPO Radical
(Elsevier BV, 2019-07)The massive-scale integration of renewable electricity into the power grid is impeded by its intrinsic intermittency. The aqueous organic redox flow battery (AORFB) rises as a potential storage solution; however, the choice ... -
Near-canopy horizontal concentration heterogeneity of semivolatile oxygenated organic compounds and implications for 2-methyltetrols primary emissions
(Royal Society of Chemistry (RSC), 2021)This study calls attention to the primary emissions of semivolatile oxygenated organic compounds (SV-OVOCs) and demonstrates how mapping out the near-canopy concentration can effectively isolate atmospheric SV-OVOC production ... -
pH swing cycle for CO2 capture electrochemically driven through proton-coupled electron transfer
(Royal Society of Chemistry (RSC), 2020)We perform a thermodynamic analysis of the energetic cost of CO2 separation from flue gas (0.1 bar CO2(g)) and air (400 ppm CO2) using a pH swing created by electrochemical redox reactions involving proton-coupled electron ... -
Potential Revenue and Breakeven of Energy Storage Systems in PJM Energy Markets
(Springer Science and Business Media LLC, 2018-10-30)The operation in energy arbitrage markets is an attractive possibility to energy storage systems developers and owners to justify an investment in this sector. The size and the point of connection to the grid can have ... -
Satellite Analysis of the Environmental Impacts of Armed-Conflict in Rakhine, Myanmar
(Elsevier BV, 2021-08)The impacts of armed conflict on the environment are extremely complex and difficult to investigate, given the impossibility of accessing the affected area and reliable data limitation. Very-high-resolution satellite ... -
Synergistic Uptake by Acidic Sulfate Particles of Gaseous Mixtures of Glyoxal and Pinanediol
(American Chemical Society (ACS), 2020-08-25) -
Vertical Profiling of Fine Particulate Matter and Black Carbon by Using Unmanned Aerial Vehicle in Macau, China
(Elsevier BV, 2020-03)An unmanned aerial vehicle 1 (UAV) equipped with miniature monitors was used to study the vertical profiles of PM2.5 (particulate matter [PM] with a ≤2.5-μm diameter) and black carbon (BC) in Macau, China, from the surface ...
