Beyond their biocompatibility, implanted electrodes for neuromuscular stimulation require careful consideration of conductivity, stability, and charge delivery capacity (CDC) to avoid irreversible faradaic reactions. To study these requirements, metal electrodes of platinum (Pt), gold (Au), and t...

Nanosized materials have been an important subject in basic and applied sciences. A novel, low-cost, green and reproducible bacteria, Aeromonas hydrophila mediated biosynthesis of titanium dioxide nanoparticles (TiO2 NPs) was reported. The resulting nanoparticles were characterized by FTIR, XRD, ...

The present study demonstrated that the combined use of the sonocatalytic reaction (using ultrasound and titanium dioxide) and the Fenton reaction exhibited synergistically enhanced hydroxyl (OH) radical generation. Dihydroxybenzoic acid (DHBA) concentration as index of OH radical generation was ...

C(sp2) bonds. The replacement of the copper catalyst with iron and titanium compounds improved the situation, but the use of photocatalysis to induce the one-electron reduction and activation of the diazonium salts is even more advantageous. The first photocatalyzed Pschorr cyclization was publis...

Nicely decorated: A sandwich-structured photocatalyst shows an excellent performance in degradation reactions of a number of organic compounds under UV, visible light, and direct sunlight. The catalyst was synthesized by a combination of nonmetal doping and plasmonic metal decoration of TiO2 nano...
