Energy‐Efficient, Sustainable Cascade Glucose Electrooxidation into Glucaric Acid

Advanced Materials, EarlyView.
This study presents a tandem system that efficiently converts glucose into glucaric acid while generating renewable electricity. By decoupling the oxidation process into two cascaded steps, the system achieves an overall 90% Faradaic efficiency and 80% conversion efficiency at ∼0.6 VRHE, significantly reducing energy consumption compared to traditional

Estimates of vertical turbulent mixing used to determine a vertical gradient in net and gross oxygen production in the oligotrophic South Pacific Gyre

Geophysical Research Letters, 2016
Mixed layer (ML) gross (GOP) and net (NOP) oxygen production rates based on in situ mass balances of triple oxygen isotopes (TOI) and O2/Ar are influenced by vertical transport from below, a term traditionally difficult to constrain.

Increased Drought Impacts on Vegetation Productivity in Drylands Under Climate Change

Geophysical Research Letters
Drought plays a critical role in the terrestrial carbon cycle, influencing both ecosystem disturbances and carbon sink dynamics. Here, we assess the effects of future droughts on gross primary production (GPP) under different Shared Socioeconomic ...
