Surface‐Bound Superoxide Radical‐Mediated Photo‐Fenton Mineralization of Ciprofloxacin on Fe‐Sillenite Nanosheets

Advanced Science, EarlyView.
This study systematically compares the degradation efficiency of CIP in a H2O2‐alone system and a novel Bi12FeO20‐H2O2 photo‐Fenton system. It reveals for the first time the presence of a quinone‐imine intermediate in the H2O2‐alone system, which exhibits toxicity comparable to CIP.

Review: Insight on Porous Carbon Positive Electrode for Sodium‐Ion Capacitors: Interplay Between Synthesis, Properties, and Performance

Advanced Science, EarlyView.
Sodium ion capacitor (SIC) is currently constrained by the low discharge capacity of commercial activated carbon as positive electrode material. This review provides a holistic summary of research efforts on alternative porous carbon materials for SIC. Image created by the authors with www.biorender.com.

SYNTHESIS AND CATECHOLASE ACTIVITY OF Cu(II) AND Fe(III) COMPLEXES OF 4-METHYL-2-((PIPERIDIN-1-YL)METHYL)PHENOL

Scientific Study & Research: Chemistry & Chemical Engineering, Biotechnology, Food Industry, 2020
This study is aimed at evaluating the impact of N- and S- bonding modes of thiocyanate substituent on catecholase activity as its presence in the coordination sphere of the metal complex can either reduce catecholase activity or otherwise. 4-Methyl-2-(

Plant‐Derived Melatonin Inhibits Bacterial Virulence via CpxA/R Two‐Component System

Advanced Science, EarlyView.
Plant‐derived melatonin is sensed by CpxAE48/T51, which inhibits the phosphorylation cascade transmission from CpxAH240 to CpxRD52, resulting in the inhibition of DNA‐binding capacity of CpxR and subsequent T3SS genes expression in Pst DC3000. ABSTRACT In defending against pathogens, plants deploy diverse secondary metabolites and signaling molecules ...

A Low‐Permeability TEMPO‐Phosphate as an Anionic Posolyte for Aqueous Redox‐Flow Batteries

Angewandte Chemie, EarlyView.
Phosphate groups are appended to TEMPO‐based active materials for use in aqueous redox‐flow batteries. In addition to improving water‐solubility, these dianionic groups are strongly repelled by the cation‐exchange membrane, thus greatly reducing TEMPO crossover.

Bandgap‐Dependent Doping of Semiconducting Carbon Nanotube Networks by Proton‐Coupled Electron Transfer for Stable Thermoelectrics

Advanced Electronic Materials, EarlyView.
Proton‐coupled electron transfer doping with benzoquinone is applied to p‐dope dense films of semiconducting single‐walled carbon nanotubes. The doping efficiency depends on the pH of the doping solution and the bandgap of the nanotubes. The highest conductivities and power factors are achieved for small‐bandgap nanotubes, remaining stable for over 120

Photoenzymatic Hydroalkylation Enables Streamlined Access to Aryl Glutarimide Precursors

Angewandte Chemie, EarlyView.
We report a photoenzymatic hydroalkylation that enables streamlined, stereocontrolled access to aryl glutarimide precursors relevant to targeted protein degradation. Engineered flavin‐dependent “ene”‐reductases provide broad scope and high enantioselectivity through a distinct electron transfer–enantioselective proton transfer pathway.

Wood‐Based Bioelectronics: Lignosulfonate‐Based Conductive Biocomposites for Paper Organic Electrochemical Transistors

Advanced Electronic Materials, EarlyView.
Biodegradable wood‐based bioelectronics are realized by integrating poly (2,3‐ethylenedioxythiopene:lignosulfonate (PEDOT:LigS) as a mixed ionicelectronic channel in organic electrochemical transistors fabricated on paper substrates. The biocomposite exhibits high conductivity, biocompatibility, and strong transistor performance, while devices built on

Fabrication of Composite Cathode for All‐Solid‐State Sodium Batteries

Advanced Energy Materials, EarlyView.
The design of composite cathodes for all‐solid‐state sodium batteries must address three critical challenges—interfacial side reactions, interfacial delamination, and highly tortuous transport pathways. This work outlines structural and interfacial strategies to optimize ion transport and mechanical stability, enabling durable, and high‐performance ...

An Overview of Polyphenols and Color Chemistry in Cocoa

AgriFood: Journal of Agricultural Products for Food, EarlyView.
Cocoa polyphenols have been traditionally known for their beneficial properties in human health. However, less is known about their other impacts on cocoa processing. This review highlights current discoveries in the role of polyphenols in the formation of color in cocoa.
