Graphene is the material of future, and carbon nanotubes have a graphene structure that is very strong and lightweight, allowing a space elevator construction. Their production enables incorporation of nano grains of iron, but also of uranium. Thanks to graphene neutron reflective properties, it is possible to design a space-powered nanoreactor.

At present, it is possible to determine the properties of a given material, without a need for synthesis and experimental measurements, by means of calculations, but these are time-consuming and cannot be used for larger quantities (about 103 or more) of potential new materials. The aim of the lecture will be to show how machine learning can speed up the discovery of new materials.

I will review shortly modelling of composition of the early Universe after recombination. I will list the relevant ionic, atomic and molecular species present in this era, show important reactions among them and give some information on relevance of such results for the structure of observable Universe and possible observable quantities in forthcoming missions.
