Investigating photocatalytic degradation of o-nitrophenol and p-nitrophenol over efficient CoO-Fe2O3@SiO2@TiO2 nanocomposite: rank annihilation factor analysis approach

Sayyed Hashem Sajjadi

In the present work, photocatalytic degradations of o-nitrophenol (ONP) and p-nitrophenol (PNP) were carried out using CoO-Fe2O3@SiO2@TiO2 nanocomposite as an efficient and cost-effective photocatalyst under simulated solar irradiation. Due to the acid-bas ...

The Role of Conserved Residues in the DEDDh Motif: the Proton-Transfer Mechanism of HIV-1 RNase H

RNase H is a prototypical example for two-metalion catalysis in enzymes. An RNase H activity cleaving the ribonucleic acid (RNA) backbone of a DNA/RNA hybrid is present not only in important drug targets, such as the HIV-1 reverse transcriptase, but also i ...

The Solvent Effect on H2O2 Generation at Room Temperature Ionic Liquid|Water Interface

Hubert Girault

H2O2 is a versatile chemical and can be generated by the oxygen reduction reaction (ORR) in proton donor solution in molecular solvents or room temperature ionic liquids (IL). We investigated this reaction at interfaces formed by eleven hydrophobic ILs and ...

Investigating Tetrel-Based Neutral Frustrated Lewis Pairs for Hydrogen Activation

Shubhajit Das

Tetrel Lewis acids are a prospective alternative to commonly employed neutral boranes in frustrated Lewis pair (FLP) chemistry. While cationic tetrylium Lewis acids, being isolobal and iso(valence)electronic, are a natural replacement to boranes, neutral t ...

Role of glutathione S-transferases and the mercapturic acid pathway in the biotransformation potential of two zebrafish (Danio rerio) test systems: early life stages and PAC2 cells

Alena Tierbach

Zebrafish (Danio rerio) early life stages provide an important model for chemical risk assessment due to their genetic similarity to humans and the availability of well-established high-throughput techniques. Cells isolated from zebrafish conserve all thes ...
