Transnational youth networks: an evolving form of public diplomacy to accelerate the Sustainable Development Goals

Autor: Matias Acosta, Zsofia Szlamka, Mohammed A. Mostajo-Radji

According to the United Nations (UN), 41% of the world’s population is under the age of 24 (United Nations Population Division). Despite being a considerably large group, the youth has been commonly underrepresented in decision-making in the public

Publikováno v: Journal of the European Ceramic Society. 38:2511-2519

In this work, the relationship between the structural mechanisms and macroscopic electrical properties of the Nb-modified 0.96(Bi0.5Na0.84K0.16TiO3)–0.04SrTiO3 (BNKT–ST) system were elucidated by using temperature dependent and in situ synchrotro
