Next generation fuel cells based on semiconductor-ionic principle
Heterostructure oxide material interfaces show extraordinary material properties such as great enhancement in the ionic conductivity, which is useful for fuel cells. We report a semiconductor-ionic
heterostructure La0.6Sr0.4Co0.2Fe0.8O3-δ (LSCF) and Sm-Ca co-doped ceria (SCDC) material possessing unique properties for new generation fuel cells using semiconductor-ionic heterostructure composite materials.The LSCF-SCDC system contains both ionic and electronic conductivities, above 0.1 S/cm, but used as the electrolyte for the fuel cell it has displayed promising performance in terms of OCV (above 1.0 V) and enhanced power density (ca. 1000 mW/cm2 at 550 °C). The work was done by an international researcher group with participation of Prof. Peter Lund from Aalto University and Hubei University. The results were recently published in Nanoenergy 37(2017)195-202. http://dx.doi.org/10.1016/j.nanoen.2017.05.003

Measuring urban nature: new habitat types and criteria support the prevention of biodiversity loss
A recent report introduces an anthropogenic habitat classification and assessment criteria that make it possible to visualize, measure, and compare nature in the built environment. These tools enable the assessment of ecological condition and support the development of green infrastructure and the prevention of biodiversity loss in cities.Online Writing retreats for doctoral students in Finnish in spring 2026
