Just like toothpaste: Fluoride radically improves the stability of perovskite solar cells
Solar cells made of perovskite hold much promise for the future of solar energy. The material is cheap, easy to produce and almost as efficient as silicon, the material traditionally used in solar cells. However, perovskite degrades quickly, severely limiting its efficiency and stability over time. Researchers from Eindhoven University of Technology, energy research institute DIFFER, Peking University and University of Twente have discovered that adding a small amount of fluoride to the perovskite leaves a protective layer, increasing stability of the materials and the solar cells significantly. The solar cells retain 90 percent of their efficiency after 1000 hours operation at various extreme testing conditions. The findings are published today in the leading scientific journal Nature Energy.

Planetary scientists unravel mystery of Egyptian desert glass
A Curtin University researcher has solved a nearly 100-year-old riddle by discovering that glass found in the Egyptian desert was created by a meteorite impact, rather than atmospheric airburst, in findings that have implications for understanding the threat posed by asteroids.

Exploring people's perception of geometric features, personalities and emotions in videos with virtual humans
Researchers at Pontifical Catholic University of Rio Grande do Sul have recently carried out a study aimed at evaluating people's perceptions of geometric features, personalities and emotions presented in video sequences with virtual humans. Their study, outlined in a paper pre-published on arXiv, merges computer science tools with psychology research practices.

New surface treatment could improve refrigeration efficiency
Unlike water, liquid refrigerants and other fluids that have a low surface tension tend to spread quickly into a sheet when they come into contact with a surface. But for many industrial process it would be better if the fluids formed droplets, which could roll or fall off the surface and carry heat away with them.

Negative personal experiences add meaning to life
While many people say they appreciate positive experiences more than negative ones, there is a hidden benefit of negative experiences. While someone involved in a negative situation might not enjoy it, a recent study from the University of Minnesota and Stanford University indicates that a negative experience can provide meaning for the individual.

'Reporter islets' in the eye may predict autoimmunity in type 1 diabetes
Identifying a reliable biomarker to predict the onset of autoimmunity in type 1 diabetes (T1D) has eluded scientists. As a result, T1D is typically diagnosed long after the majority of insulin-producing cells have been irreversibly destroyed. Unlike the onset of other autoimmune diseases which can be seen on the body or felt through symptoms, the attack on the islets cannot be observed because they reside deep within the pancreas.
