1. Neutron scattering for sustainable energy materials: investigations of proton dynamics in acceptor doped barium zirconates
Sammanfattning : Proton conducting oxides are currently receiving considerable attention for their present or potential use as electrolytes in technological devices such as sensors and electrolysers and, in particular, solid oxide fuel cells, which are among the most promising apparatuses for energy conversion. One of the main challenges for these latter devices is to combine the advantages of a solid electrolyte with those of operational temperatures below 750 °C, which is currently hampered by insufficient conductivities in the targeted temperature range.

2. Conducting Foams and Fibres for Bulk Plastic Thermoelectrics
Sammanfattning : The use of small portable electronics in society is constantly increasing, thus the demand for portable power sources also rises in turn. Portable electronic devices rely upon energy stored in batteries to power them, which in turn require regular access to power outlets to be recharged. LÄS MER
3. Functional Oxide Materials exhibiting Ionic Conductivity for Future Energy Conversion Needs
Sammanfattning : Fuel cells are electrochemical devices that transform the chemical energy in hydrogen and oxygen into electrical energy at high efficiencies and produce only water vapour emissions. Materials with the perovskite or fluorite structure types are commonly employed as the ion conducting ceramic electrolyte membranes in intermediate and high temperature fuel cells. LÄS MER
4. Self-doped Conjugated Polyelectrolytes for Bioelectronics Applications
Sammanfattning : Self-doped conjugated polyelectrolytes (CPEs) are a class of conducting polymers constituted of a π-conjugated backbone and charged side groups. The ionic groups provide the counterions needed to balance the charged species formed in the CPEs backbones upon oxidation. LÄS MER
5. Electrically Conducting Yarns for Electronic Textiles
Sammanfattning : Electronic textiles (e-textiles) present a huge opportunity to incorporate wearable devices into textiles. Electrically conducting yarns and fibers can be utilized to create these e-textiles. For e-textiles to be wearable the development of electrically conducting yarns needs to rely on materials that are neither scares nor toxic. LÄS MER
