Nitroflavone Derivatives Inhibit the Production of Actinorhodin in Streptomyces coelicolor [PDF]
Current Issues in Molecular BiologyStreptomyces coelicolor M145 (SC) is a model strain characterised by its highly active oxidative metabolism. This results in high levels of oxidative stress and the production of actinorhodin (ACT), a blue polyketide pigment with antioxidant properties ...

Micro‐Environment Programmable Quinoline COFs for High‐Performance Photocatalytic H2O2 Generation and Benzylamine Coupling [PDF]
Advanced SciencePhotocatalytic H2O2 synthesis from water and oxygen by covalent organic frameworks (COFs) has attracted much attention currently. However, conventional COFs often suffer from insufficient stability and activity due to the unclear structure‐activity ...

Dual‐Substrate Synergistic Photocatalysis: Exogenous Reagent‐Free Co‐Removal of Phenol and Cr(VI) via Electron‐Donor‐Mediated Redox Coupling over Modified Carbon Nitride [PDF]
Advanced ScienceTraditional photocatalytic systems for pollutant removal depend on exogenous oxidants or sacrificial agents, hampering sustainability. Herein, we report an exogenous reagent‐free dual‐substrate cooperative strategy. Without adding external chemicals (e.g.

The Proton Dissociation of Bio-Protic Ionic Liquids: [AAE]X Amino Acid Ionic Liquids
Molecules, 2020 [AAE]X composed of amino acid ester cations is a sort of typically “bio-based” protic ionic liquids (PILs). They possess potential Brønsted acidity due to the active hydrogens on their cations. The Brønsted acidity of [AAE]X PILs in green solvents (water
