Forging Sustainable Carbon–Nitrogen Bonds from CO2 and NOx: Mechanistic Insights and Catalyst Design for Electrochemical CN Coupling

open access: yesChemSusChem, Volume 19, Issue 9, 14 May 2026.
Electrochemical CN coupling enables the direct conversion of CO2/CO and NOx into value‐added organonitrogen compounds under mild and sustainable conditions. Catalyst architecture governs the coactivation of carbon and nitrogen intermediates and their interfacial coupling, dictating reaction pathways, selectivity, and efficiency.

Estimation of Bilirubin Using Acetamide

open access: yesClinical Chemistry, 1964
Abstract A study of the effect of acetamide as an accelerator of the reaction between free bilirubin and diazotized sulfanilic acid (DSA) has led to its use in a method for serum bilirubin which is simple, sensitive, linear over a wide range, and which requires neither excessive dilution nor protein precipitation.

O2‐Mediated Cu‐Catalyzed Dehydrogenative Sulfilimination of Tyrosines and Bioactive Phenols

open access: yesAdvanced Synthesis &Catalysis, Volume 368, Issue 9, 5 May 2026.
We report herein the mild O2‐mediated Cu‐catalyzed dehydrogenative sulfilimination of diverse bioactive phenols with simple sulfenamides. The bioconjugation of unmodified native peptides, in particular at their tyrosine units with the dehydrogenative phenochalcogenazination reaction, has attracted much attention lately due to potential click type ...

The conversion of citrulline to arginine in kidney [PDF]

open access: yes, 1941
Glycocyamine is formed in the kidney by the transfer of the amidine group of arginine to the nitrogen atom of glycine. In the study of this reaction it was observed that glycocyamine was also formed from citrulline and glycine.
