Research synergy from different fields, research institutes and countries has resulted in the discovery of near-unbreakable materials. These materials are long-sought after polymeric carbon nitrides predicted to rival the hardness of diamond, while showing a wide range of further properties with possible applications in a broad range of fields.

鈥淭he multi-functionality of these materials is as important as their predicted hardness, which may lead to their application in fields where diamond doesn鈥檛 offer desired combinations of properties鈥, says Florian Trybel, assistant professor at Link枚ping University, part of the discovery team and co-author to the article. 鈥淎t the moment, the synthesis pressures and temperatures of these materials are too high to produce large quantities efficiently. Theoretical simulations will play an important role in predicting new synthesis pathways at less extreme pressure and temperature conditions. This will enable us to further investigate their outstanding properties and move towards industrially relevant scales.鈥, he adds.

The researchers stress that the international collaboration 鈥 led by experimentalists from the University of Edinburgh and the University of Bayreuth, as well as theorists from the Theoretical physics division at Link枚ping University 鈥 with diverse backgrounds and scientific fields was the key to a successful discovery. The article resulting from this discovery has been a success in its own right, receiving much attention, see .

New visiting professor focuses on municipalities in times of crisis

Municipalities are cornerstones of Swedish society, but what happens if a crisis strikes? What legal scope do municipalities have to deal with serious incidents? These are some of the questions Johan Höök wants to explore as new visiting professor.
