When talking about research, I must mention Mrs. Rita Wagner, a superb technician that
looked after my laboratory and the younger Ph. D. students for about 25 years. Some of her …

The trace amounts of “free” iron can catalyse production of a highly toxic hydroxyl radical via
Fenton/Haber–Weiss reaction cycle. The critical factor appears to be the availability and …

Metal nanoparticles (NPs), and in particular Au NPs, dispersed on an oxide support often
show a much higher catalytic activity than the single-component NPs.[1–6] Such catalytic …

Iron is an essential cofactor for important biological activities and biochemical reactions,
including the transport of oxygen via red blood cells and its reduction to water during …

Enzyme catalase seems to be the main regulator of hydrogen peroxide metabolism.
Hydrogen peroxide at high concentrations is a toxic agent, while at low concentrations it …
