Silica Aerogels: A Review of Molecular Dynamics Modelling and Characterization of the Structural, Thermal, and Mechanical Properties

Submitted by Jingjie Yeo on

https://doi.org/10.1007/978-3-319-50257-1_83-1 The second volume of the Handbook of Materials Modeling is now online: We reviewed the development of new empirical molecular dynamics forcefields, novel methods of generating aerogels’ percolated backbones, and compelling algorithms for characterizing their structural, mechanical, and thermal properties that have resulted in unprecedented insights into silica aerogels.

Tetrahedral: The key to life on Earth?

Submitted by Rod Ruoff on

It seems to me that tetrahedral bonding is responsible for life on earth. 

One might leap to the (reasonable) conclusion that I am referring to the element carbon and its ability to form sp3 bonds.  Life does depend on carbon, no doubt. But where does life exist, by and large?
