Supramolecularly Directed Confined Crystallization of Lamellar Carbon Nitride for Efficient Photocatalytic Hydrogen Generation

Advanced Energy Materials, Volume 16, Issue 22, 10 June 2026.
ABSTRACT Sustainable hydrogen generation through water splitting is key to realizing a future hydrogen economy. In this study, we achieved molecular‐level control over self‐assembled supramolecular complexes of cyanuric acid and 3‐amino 1,2,4 triazole (AT) monomers. This was coupled with molten‐salt‐assisted thermal polymerization in a eutectic mixture

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 ...

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.

Metal–Organic Frameworks as Programable Platforms for Micro‐ and Optoelectronics: From Dielectrics to Semiconductors and White‐Light Emitters

Small Science, Volume 6, Issue 6, June 2026.
Programable metal–organic framework (MOF) architectures are revealed as versatile micro‐ and optoelectronic platforms, spanning low/high‐κ dielectrics, semiconductive frameworks, and electrically driven phosphor‐free white emitters. Metal nodes, π‐conjugated linkers, guests, and confined water emerge as decisive handles for tuning charge transport ...
