Box Models of Volatile Cycles over the Entire Phanerozoic [PDF]

, 2006
Three stand-alone geochemical box models have been developed to simulate globally coupled biogeochemical cycles. These models reflect the evolution of the participating biotic and abiotic constituents in marine and terrestrial environments, including the

Heteroatom‐Doped Graphdiynes and Their Applications in Photo‐/Electro‐Catalytic CO2 Conversion

Carbon Innovation, EarlyView.
This review highlights the versatile role of doped graphdiyne (GDY) in boosting CO2 conversion, where metal and non‐metal doping simultaneously tune the electronic structure, create abundant active sites, and improve charge separation, light harvesting, and CO2 adsorption.

1,2‐Diazetidines − Structure, Synthesis, and Functionalization

European Journal of Organic Chemistry, EarlyView.
1,2‐Diazetidines are saturated four‐membered heterocycles featuring two adjacent nitrogen atoms. Despite recent advances in their synthesis and promising potential in medicinal chemistry, the chemistry of these cyclic hydrazines remains underexplored.

Monitoring and Mitigation Strategies for Hazardous Compounds in Chinese Rice Wine (Huangjiu): A Comprehensive Review

Food Safety and Health, EarlyView.
This review elucidates the formation pathways and detection technologies for ethyl carbamate, biogenic amines, and higher alcohols in Huangjiu. It concludes that integrated control frameworks are essential to decouple safety risks from the metabolic processes responsible for flavor development.

An improved narrower-diameter EA/IRMS method with a built-in desulfurization reactor: optimization for nitrogen and carbon measurement without sulfur matrix interference

Progress in Earth and Planetary Science
Elemental analysis with isotope ratio mass spectrometry (EA/IRMS) is a widely used technique for stable isotope ratio analysis of nitrogen and carbon. Although the narrower-diameter EA/IRMS method developed to date has effectively enhanced sensitivity ...
