Synthesis and Characterization of Erbium Oxide Nanocrystallites.

The present article describes a method of the preparation of erbium oxide nanocrystallites (nano Er₂O₃) via thermal decomposition of a transient complex formed from Er(NO₃)₃·5H₂O and glycine. Decomposition of the complex occurred at about of (250±10) °C. Ultra-fine light pink powder of erbium oxide nanocrystallites was obtained via this method.

Determination of Oxidative Potential Caused by Brake Wear Debris in Non-Cellular Systems.

Wear debris from automotive brake systems represents a major source of non-exhaust emissions from road traffic and its production increases with number of cars worldwide. However, impact of brake wear debris on the environment and organisms is still not clear. One of the most possible ways by which these particles may affect living organisms is oxidative stress.
