A Roadmap for Plasma‐Enabled Electrocatalysis in Urea Production

open access: yesAdvanced Materials, EarlyView.
A modular plasma—electrochemical platform enables fully electrified urea synthesis from air and CO2 under ambient conditions. This Review integrates plasma oxidation, C─N coupling electrolysis, mechanistic insights, and techno‐economic metrics into a roadmap for scalable, distributed, and renewable fertilizer production.

Deep carbon cycles constrained by a large-scale mantle Mg isotope anomaly in eastern China

open access: yes, 2017
Although deep carbon recycling plays an important role in the atmospheric CO2 budget and climate changes through geological time, the precise mechanisms remain poorly understood.

Photocatalytic Aqueous Reforming of Methyl Formate

open access: yesAdvanced Materials, EarlyView.
A 3d‐metal Cu‐based atomically dispersed photocatalyst, supported on modified g‐C₃N₄, facilitates the photocatalytic selective hydrogen (7.5 mmol gcat−1 of hydrogen; nothing else than H2 and CO2) generation from methyl formate. This diverse system functions under mild conditions, providing high hydrogen yield, selectivity, and enduring stability ...

Variation in the isotopic signatures of juvenile gray snapper (Lutjanus griseus) from five southern Florida region [PDF]

open access: yes, 2010
Measurements of 18O/16O and 13C/12C ratios in the carbonate of juvenile gray snapper (Lutjanus griseus) sagittal otoliths collected during 2001–2005 from different southern Florida regions indicated significant variations in the ratios between Florida ...

Confining Quantum Dots Within Covalent Organic Framework Cages for Coupled CO2 Photoreduction and Value‐Added Chemical Synthesis

open access: yesAdvanced Materials, EarlyView.
A 3D/0D S‐scheme heterojunction photocatalyst is constructed by spatially confining ZnSe quantum dots within covalent organic framework (COF) porous cages, enabling coupled CO2 photoreduction and value‐added chemical synthesis. COF porous cages serve as nanoreactors, enriching reactant concentrations, and the S‐scheme heterojunction facilitates charge ...

Using isotopic fingerprints in gastropod shells to validate commercial production pathway and geographic provenance

open access: yesRoyal Society Open Science
Growing demand for high-value seafood is fuelling provenance fraud, which threatens the sustainability of wild fisheries while posing biosecurity and human health risks.
