Published in 2017 at "Journal of Geophysical Research"

DOI: 10.1002/2016jg003698

Abstract: Streams, rivers, and other freshwater features may be significant sources of CH4 to the atmosphere. However, high spatial and temporal variabilities hinder our ability to understand the underlying processes of CH4 production and delivery to… read more here.

Published in 2018 at "Reviews of Geophysics"

DOI: 10.1002/2017rg000559

Abstract: Methane (CH4) is produced in many natural systems that are vulnerable to change under a warming climate, yet current CH4 budgets, as well as future shifts in CH4 emissions, have high uncertainties. Climate change has… read more here.

Published in 2022 at "Advanced Materials"

DOI: 10.1002/adma.202200057

Abstract: Selective photoreduction of carbon dioxide (CO2) into carbon‐neutral fuels such as methane (CH4) is extremely desirable but remains a challenge since sluggish multiple proton–electron coupling transfer and various C1 intermediates are involved. Herein, a synergistic… read more here.

Published in 2018 at "Chemphyschem"

DOI: 10.1002/cphc.201701212

Abstract: Abstract We describe the synthesis and characterisation of open fullerene (1) and its reduced form (2) in which CH4 and NH3 are encapsulated, respectively. The 1H NMR resonance of endohedral NH3 is broadened by scalar coupling… read more here.

Published in 2023 at "ChemSusChem"

DOI: 10.1002/cssc.202300604

Abstract: A Sonogashira coupling reaction leads to the formation of a serendipitous product C with the 3,3'-(ethane-1,2-diylidene)bis(indolin-2-one) unit. To our knowledge, our study provides the first example demonstrating that electron transfer between isoindigo and triethylamine can… read more here.

Published in 2021 at "Journal of environmental quality"

DOI: 10.1002/jeq2.20250

Abstract: Riparian zones provide multiple benefits including streambank stabilization and nutrient abatement. But there is a knowledge gap on how the type of vegetation and environmental factors (e.g., soil temperature, moisture) within the riparian zone influence… read more here.

Published in 2022 at "Journal of environmental quality"

DOI: 10.1002/jeq2.20336

Abstract: Swine manure is kept in outdoor storages until it is applied to cropland. Anaerobic conditions facilitate microbial methane (CH4 ) production at a rate that depends on temperature. Manure CH4 emissions can be the largest… read more here.
