Graphene augmented ceramic nanofibers and their applications
The current progress in key areas from construction and transportation to energy generation/storage and bio-applications increasingly demands new structural materials with improved and multifunctional performance. To be adapted by industry, these materials will not only have to be lighter, stronger and tougher but also play additional functional roles, including sensing external stimuli, self-monitoring their structural health, conducting electricity and/or storing energy. The main focus of the work is on special-purpose materials based on the unique Estonian product – functionalized metal oxide nanofibers of a great aspect ratio (107) to be used as (i) additives to ceramics, (ii) customized scaffolds, (iii) electrocatalyst support, and (iv) electrochemical sensors.

Saving Science and Society
In today's public debate, science is under wicked pressure: we need to achieve results faster and with broader societal impact. While it is true that science needs to be directed more towards tackling the greatest challenges of our times (such as the UN's Sustainable Development Goals), it is also true that science needs to keep a perspective that looks beyond the known horizon. How to achieve the balance between these expectations?

Oxidative Chemical Degradation of Oil Shale.
Oil shale processing starts from thermal decomposition of oil shale to shale oil, gas and semi-coke. These primary products and the formed byproducts form a feedstock for further chemical transformation and valorization. A direct chemical destruction of oil shale may be an alternative to the traditional, yielding different products and opening new possibilities.

Intermittency and scale invariance in nature and in society
We consider such intermittent systems as turbulent media and society/econosphere. Intermittency means that the system behaviour cannot be described by Gaussian statistics. Typically, intermittent systems behave in a very complicated and diverse manner, giving rise to the formation of various power laws, multiscaling, and/or to the creation of scale-free networks.

Mineral Carbonation of Post Industrial Materials: Engineering a natural process for operational optimization and CO2 management
Mineral carbonation is a naturally occurring process that takes place in nature in all latitudes at ambient temperature and pressure. This relatively simple process can be engineered to increase reaction efficacy and increased carbonate yield. The substrate materials can be readily sourced from post-industrial waste products including slags and mine tailings. The cost associated with the large energy inputs from comminution of materials is generally absorbed by the extraction of the mineral of interest and additional inputs are negligible. The economic flow-on comes in the form of newly created building materials and CO2 offset credits containing sequestered greenhouse gases. This presentation will look at the mineral carbonation from natural analogues through engineered systems and explore the economic and social benefits of this simple chemical process.
