Corn response to biological products and a nitrification inhibitor

Agrosystems, Geosciences &Environment, Volume 9, Issue 2, June 2026.
Abstract Atmospheric nitrogen (N2) is converted into ammonia (NH3), a form that plants can use, through biological nitrogen (N) fixation by various microorganisms and bacterial genera. This study assessed the field performance of three biological N‐fixing products, or biostimulants (BS), including Gluconacetobacter diazotrophicus (BS1), Klebsiella ...

Reactions of 3-phenyl-1,2,4-triazine with some C-nucleophiles [PDF]

, 2013
Dimedone is added at C(5) of 3-phenyl-1,2,4-triazine to give stable dihydro derivative. Its reaction with 1-aryl-3-methylpyrazol-5- ones proceeds with fragmentation affording 1,1,2,2-tetrakispyrazolylethane and amidrazone derivatives.

S‐Doped Carbon Nitride Thin Films From a Triazole Precursor

Carbon Innovation, Volume 1, Issue 1, Page 78-85, June 2026.
Sulfur‐functionalized carbon nitride thin films are synthesized via low‐temperature chemical vapor deposition using a triazole‐derived precursor. Tunable sulfur incorporation modulates electronic and optical properties and enables efficient visible‐light photocatalysis with high conversion and selectivity.
