Polyaniline as a dual flame retardant and electrostatic dissipative additive in polyethylene nanocomposites

Journal of Vinyl and Additive Technology, Volume 31, Issue 2, Page 339-355, March 2025.
Effecft of co‐doping polyaniline with phosphoric acid and phytic acid on the heat release rate of polyethylene. Abstract Polyolefins, such as polyethylene (PE), are highly flammable and electrically insulative, limiting their applicability. The study explored the flame‐retardancy and electrical conductivity of PE/polyaniline (PE/PANI) nanocomposites ...

Tuning the Photochemistry of Entatic State Model Systems

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
We present the photochemistry of the entatic state model [Cu(DMEGqu)2]+/2+, a copper guanidino‐quinoline complex pair. By transient IR and UV/Vis spectroscopy, we obtained the lifetimes of the different excited states. We show that the structural effect of the guanidine tunes the photochemistry of this entatic state model.

A Trinuclear Manganese(II) Complex Bridged by a Triaminoguanidine‐Based Schiff Base Ligand: Structure and Magnetic Properties

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
A triaminoguanidine‐based Schiff base ligand enables the directed assembly of a trinuclear manganese(II) complex with an almost equilateral triangular topology. Weak antiferromagnetic exchange interactions in combination with axial zero‐field splitting govern the magnetic behavior of the Mn3 core. A triaminoguanidine‐based Schiff base ligand provides a

Plant organelle C‐to‐U RNA editing factors can operate successfully in yeast (Saccharomyces cerevisiae) as an easily amenable eukaryotic system for their functional analysis

The FEBS Journal, EarlyView.
Plant‐type pentatricopeptide repeat proteins capable of C‐to‐U RNA editing perform faithfully when expressed in a new heterologous system, the yeast Saccharomyces cerevisiae. They were tested with constitutive and inducible expression and with a set of different solubility tags. PPR56, PPR65, and PPR78 from P.
