The biogenesis of phenazine pigments

, 1961
Pigments that contain the aromatic phenazine nucleus such a spyocyanine (I), chlororaphin (a 3:1 molecular compound of phenazine-1-carboxamide (II) and its 9,10 dihydro derivative), iodinin (III) and phenazine-1-carboxylic acid present an interesting ...

Electrochemically Reduced Graphene Oxide as a Support for Polyaniline‐Coated Gold Nanoparticles in Non‐Enzymatic EC‐SERS Detection of Hydrogen Peroxide

ChemElectroChem, Volume 13, Issue 17, 1 September 2026.
An enzyme‐free electrochemical surface‐enhanced Raman spectroscopy (EC‐SERS) platform is developed by combining electrochemically reduced graphene oxide (ERGO) with polyaniline‐coated gold nanoparticles (PANI@AuNPs). The ERGO layer promotes charge transfer and enables stable hydrogen peroxide (H2O2) detection over an extended concentration range ...

Impact of Organo‐Functionalization on the Light‐Driven Hydrogen Evolution Reactivity of Molecular Molybdenum Sulfides

Chemistry – A European Journal, Volume 32, Issue 33, 1 September 2026.
Organo‐functionalized molecular molybdenum sulfides were synthesized using bidentate N‐donor ligands and investigated as light‐driven homogeneous hydrogen evolution reaction (HER) catalysts. Trends observed in the HER activity of these catalysts were elucidated by combining photophysical, electrochemical and computational studies.

Charge Storage Mechanisms and Material Design of Ammonium Ion Batteries

Carbon Neutralization, Volume 5, Issue 5, September 2026.
Aqueous ammonium ion batteries (AAIBs) are promising sustainable energy storage devices, leveraging the low molar mass and rapid hydrogen bond‐facilitated diffusion of NH4+ ions. Research focuses on developing electrode materials (including metal materials and organic materials) and optimizing electrolytes to improve performance.

Excited‐State Dynamics of Fully Fused Tetrapyrazinoporphyrazine‐Based Three‐Dimensional Polymers

ChemPhotoChem, Volume 10, Issue 9, September 2026.
This study investigates the excited‐state dynamics of three‐dimensional (3D) and 2D fused aromatic network (FAN) polymers based on tetrapyrazinoporphyrazine. Dimensional π‐expansion enhances Soret‐band absorption and induces ultrafast nonradiative decay of the singlet excited state within tens of picoseconds via accelerated internal conversion.

Impacts of M. oleifera Leaf Extract on Weight Loss, the Metabolomic Profile, and the Intestinal Microbiota in Individuals With Simple Obesity

Food Science &Nutrition, Volume 14, Issue 9, September 2026.
A total of 63 subjects participated in the formal trial, randomly assigned to either the control group (n = 29) or the intervention group (n = 34). The trial period lasted 90 days, during which the intervention group consumed Moringa oleifera leaf extract while the control group received a corresponding placebo.

Microbiome‐mediated plant‐soil feedbacks as a tool for resilient agriculture

iMetaOmics, Volume 3, Issue 3, September 2026.
Translating plant‐soil feedbacks (PSFs) into reliable agricultural management requires shifting from input‐dependent practices toward endogenous, process‐driven crop resilience. To bridge this gap, we propose a predictive framework centered on three strategic interventions: engineering the crop holobiont, diversifying the soil habitat, and deploying ...

Inhibition of Photophosphorylation by Phenazine Methosulfate

Journal of Biological Chemistry, 1967
Phenazine methosulfate was shown to be a competitive inhibitor of H+ in light-induced H+ transport as well as a competitive inhibitor of orthophosphate in photophosphorylation. Similarly, H+, NH4+, and Pi in the presence of adenosine diphosphate were shown to inhibit competitively light-induced binding of phenazine methosulfate to chloroplasts. Pi, in
