The use of a hydrothermal bomb for preparation of a metal organic framework is a well-known technique in inorganic chemistry [31], However, the use of a hydro-thermal bomb for the preparation of scaffold is very rare. The final mixmre with the appropriate composition for scaffold preparation is sealed in a PTFE-lined acid digestion bomb and heated at 40°C for 8 h under autogeneous pressure. After that, the bomb is kept at room temperature to cool the product, which is then frozen at —20°C, Finally, the product is vacuum dried to obtain the desired scaffolds [32-34] (Dutta PK et al, unpublished results). 

We will occasionally refer to coordination polymer , as opposed to hydrogen bound nets, but framework and metal-organic will rarely appear. However, as scientific descendants of a long line of inorganic chemists, we will use complex and coordination throughout the text.
