ChemPhysChem, Volume 27, Issue 6, 27 March 2026.Laser irradiation of a 2,3‐diaminomaleonitrile (DAMN) molecule (white) induces decomposition into the highlighted products (yellow). The laptop denotes a computational simulation designed to mimic the laser ablation experiment. We investigate the fragmentation chemistry of 2,3‐diaminomaleonitrile (DAMN), a key hydrogen cyanide (HCN) tetramer in ...

Impacts of Low‐Level Jets on Moisture Transport to the Pantanal, Brazil
International Journal of Climatology, Volume 46, Issue 3, 15 March 2026.The moisture transports from the tropics to the subtropics by the low‐level jets (LLJs) east of the Andes crossing the Pantanal region. Four LLJs, east of the Andes, were identified and selected with correspondent Lagrangian moisture transport. The LLJ moisture source regions contribute to Pantanal (~63.5%) and precipitation increased (~30%) during LLJ

Dinuclear Rhodium(I)–N‐Heterocyclic Carbene Complexes as Alkyne Hydropyridonation Catalysts
European Journal of Inorganic Chemistry, Volume 29, Issue 7, 2 March 2026.Catalyst Improvement by NHC tuning: A series of new RhI–NHC dinuclear complexes has been revealed as efficient alkyne hydropyridonation catalysts. 333053IMes complex displays the highest reactivity of the series, suggesting that a moderate steric demand combined with balanced σ‐donation facilitates precatalyst activation and substrate exchange.

Advanced Functional Materials, Volume 36, Issue 20, 9 March 2026.The SERS spectra of reporter molecules adsorbed on chiral gold nanorods depends on the handedness of circularly polarized light (CPL‐SERS). The bisignate plasmonic CD spectra of chiral nanorods provides wavelength‐dependent CPL‐SERS. Selective discrimination of chiral nanorod handedness and different Raman reporters allow highly sensitive codification ...
