Iron is an irreplaceable component of proteins and enzyme systems required for life. This need for iron is a well-characterized evolutionary mechanism for genetic selection. However, there is limited consideration of how iron bioavailability, initially determined by planetary accretion but fluctuating considerably at global scale over geological time frames, has shaped the biosphere.

>A Kinetic Study of Micronization Grinding of Dry Mica in a ...
This paper presents results of the research of micronization grinding of dry mica in a planetary ball mill. Investigation was conducted in order to improve the quality and to obtain clearly defined properties and characteristics of mica powder. The micronization grinding of dry mica was performed in four time periods: 30, 60, 120, and 360 minutes.
>Process engineering with planetary ball mills - Chemical ...
Processes inside planetary ball mills are complex and strongly depend on the processed material and synthesis and, thus, the optimum milling conditions have to be assessed for each individual system. The present review focuses on the insight into several parameters like properties of grinding balls, the filling ratio or revolution speed.

As another example, diazomethane (H 2 C=N=N) is readily formed by either the photolysis or radiolysis of solid mixtures of N 2 and CH 4, and is thought to be present on cold outer Solar System objects such as Pluto (e.g., Bohn et al., 1994; Moore and Hudson, 2003). However, diazomethane's explosive instability and high toxicity can discourage ...
