Architectured materials for tailored mechanics
Lattice materials are a class of micro-architectured materials with potential application in several industrial sectors due to their enhanced mechanical properties toward, e.g., tailored anisotropic stiffness, crashworthiness, and lightweight. To confirm the applicability of these materials for industrial applications, different aspects of the mechanical behavior is to be investigated. For a comprehensive understanding, as the vision for long-term collaboration, tools of computational simulations at Uppsala University and experimental analyses at Nagoya University will be employed to unravel the mechanics of these materials-by-design.

Deformation mechanisms of superlattices and nanocomposite based multifunctional nanolaminates
In the field of transition metal nitrides and borides based hard coatings, the main challenge has been to realize a useful combination of hardness, damage tolerance, thermal shock resistance, and corrosion resistance properties in a single coating design. The scope of the project is to perform microtensile and microcompression tests of carefully engineered hard, stress tolerant multilayered/superlattice coatings and understand interface effects of deformation mechanisms as a function of temperature at an atomistic-to- nano/micro scale.

Develop novel solid polymer electrolytes using polyketones
The objective of this study is to develop solid polymer electrolytes using aliphatic polyketones that exhibit high lithium-ion conductivity. Through the collaboration of the groups at Hokkaido, Sophia and Uppsala Universities, polyketones were for the first time found to have great potential as ion-condutive polymers. This collaboration will design and prepare novel and practical solid polymer electrolytes using aliphatic polyketones, investigate their ion transport properties.

Exploring the potential of organic electrolytes for next-generation solar cells
Organic electrolytes play a critical role for improving the stability of new-generation solar cell devices (including organic solar cells and perovskite solar cells) while keeping high power conversion efficiency. The reason is because they are essential for modulating the energy level of transport layer and minimize the energy loss of devices. The project investigates the effect of organic electrolytes on devices perovskites with an aim of further increasing the stability and efficiency of next-generation solar cell devices, bring new-generation solar cell devices close to reality.
