Chemistry – A European Journal, EarlyView.A newly synthesized bifunctional azide—diazonium linker allows robust one‐step introduction of azido groups to single‐wall carbon nanotubes. Versatility of the azido groups as reactive handles is demonstrated by further derivatization with 6‐carboxyfluorescein and oligonucleotides.

Catalyst‐Free Selective Reduction of Nitrogen Dioxide to Nitric Oxide
Chemistry – A European Journal, EarlyView.Common main group reductants selectively convert nitrogen dioxide to nitric oxide in a catalyst‐free manner. Computational studies suggest divergent reaction pathways depending on the reductant employed. Where boranes and silanes proceed via a two‐electron process, and hydrogen surrogates undergo stepwise one‐electron processes.

Chemistry – A European Journal, EarlyView.Nitrooxylation—the installation of nitrate esters (–ONO2) has evolved from classical mixed‐acid protocols to catalytic and mechano‐, flow‐, photo‐, and electrochemical strategies. This review delineates ionic and radical manifolds for C–ONO2 bond formation, emphasizing mechanistic control, selected substrate scope, and selectivity.

Fluorogenic Sydnones for Bioorthogonal Labeling of DNA
Chemistry – A European Journal, EarlyView.Conjugates of sydnones with cyanine‐styryl dyes combine bioorthogonal reactivity with fluorogenicity. The reactivity with bicyclo[6.1.0]non‐4‐yne (BCN)‐modified DNA showed second‐order rate constants of up to k2 = 2,300 M−1s−1 and fluorescence turn‐on by one magnitude of order.

A Unified Approach for the Synthesis of Conformationally Locked and sp2‐sp3 Fused Hybrids
Chemistry – A European Journal, EarlyView.This study presents a systematic platform to build rigid sp2–sp3 hybrids via benzyne cycloadditions. Arene‑fused bicyclic oxa‐, aza‐, and carbocycles are converted into medicinally relevant amino acids and applied to Enalapril analogues synthesis. The hybrids combine aromatic interactions with 3D rigidity, tuning lipophilicity, pKa, and solubility ...

Toxicity of Total Ammonia and Nitrite Nitrogen to Young Yellowtail, Seriola quinqueradiata
, 1991 Young yellowtail (Seriola quinqueradiata) were exposed to total ammonia (NH₄-N+NH₃-N) or nitrite nitrogen (NO₂-N) in 96 hr-LC₅₀ toxicity tests. The 96 hr-LC₅₀ value of total ammonia to young yellowtail was 28 ppm, and that of nitrite nitrogen was more ...
