Nucleation‐Controlled Reconstruction of CuOx for Selective CO2 Electroreduction

open access: yesAdvanced Functional Materials, EarlyView.
The ratio of oxygen vacancies (Ov) and exposed Cu2O (111)/(200) of CuOx precatalyst is modulated by nucleation control of Cu(OH)2 precursor. Low Ov ratio and high ratio of Cu2O (111)/(200) in slow‐nucleated CuOx reconstructs to high‐coordinated oxide‐derived copper (OD‐Cu) during electrochemical CO2 reduction reaction (CO2RR) and exhibits enhanced ...

Daily Global Methane Super‐Emitter Detection and Source Identification With Sub‐Daily Tracking

open access: yesGeophysical Research Letters
We use the Visible Infrared Imaging Radiometer Suite (VIIRS) satellite instruments to retrieve atmospheric methane enhancements with 750 m resolution. We show that the three VIIRS instruments in orbit uniquely enhance tracking of methane super‐emission ...

Rice plants reduce methane emissions in high-emitting paddies [version 3; peer review: 1 approved, 2 approved with reservations]

open access: yesF1000Research, 2019
Background: Rice is understood to enhance methane emissions from paddy fields in IPCC guidelines. However, rice actually has two opposite functions related to methane: i) emission enhancement, such as by providing emission pathways (aerenchyma) and ...
