The role of polybrominated diphenyl ethers in the induction of cancer: a systematic review of insight into their mechanisms.

Environmental pollution caused by persistent organic pollutants (POPs) has increased the challenge for the scientific communities. Polybrominated diphenyl ethers (PBDEs), classified as POPs, are widely applied in various materials as brominated flame retardants (BFRs). Because of the nature of these chemical compounds including toxicity, stability, and capability to bioaccumulate and biomagnify, PBDEs have posed a great challenge and risk to human health and wildlife.

Enhanced photocatalytic performance and reusability of N-doped carbon dots/zinc oxide hybrid nanostructures.

We report the fabrication of nitrogen-doped carbon dots-zinc oxide hybrid (NCDs-ZnO) nanostructures utilizing simple chemical procedures. The role of NCDs in ZnO nanostructured matrix has been analyzed through XRD, SEM, FTIR and PL characterization techniques. The introduction of NCDs was found to modify not only their aspect ratio, observed by a reduction in the preferred-axis growth compared to the- and-axis, but also induced an additional emission around 441 nm, which is typical of NCDs.

Influence of ruthenium doping on UV- and visible-light photoelectrocatalytic color removal from dye solutions using a TiO nanotube array photoanode.

The photocatalytic activity of TiO anodes was enhanced by synthesizing Ru-doped Ti|TiO nanotube arrays. Such photoanodes were fabricated via Ti anodization followed by Ru impregnation and annealing. The X-ray diffractograms revealed that anatase was the main TiO phase, while rutile was slightly present in all samples.

Synthesis of Ruthenium-Doped TiO₂ Nanotube Arrays for the Photocatalytic Degradation of Terasil Blue Dye.

The oxidation of terasil blue dye (TB) has been achieved by photocatalysis under UV light using well organized nanotubes of Ti/TiO₂ doped with ruthenium (Ru/Ti/TiO₂). Ru/Ti/TiO₂ were fabricated by Ti anodization followed by impregnation with 0.04, 0.

Modelling of Behavior for Inhibition Corrosion of Bronze Using Artificial Neural Network (ANN).

In this work, three models based on Artificial Neural Network (ANN) were developed to describe the behavior for the inhibition corrosion of bronze in 3.5% NaCl + 0.1 M NaSO, using the experimental data of Electrochemical Impedance Spectroscopy (EIS).
