Conclusions 👌
223 |224 |
-
225 |
- materials informatics is just about how to handle materials data efficiently 226 |
- Python + ASE can do anything about the nanometers for you 227 |
- POSCAR & CIF are the most common formats for crystal structures, but the Optimade is coming 228 |
- the modern materials simulations can be prepared and even conducted fully online. 229 |
