Background: The coronavirus infectious disease-2019 (COVID-19) pandemic has led to an unprecedented shortage of healthcare resources, primarily personal protective equipment like surgical masks, and N95/filtering face piece type 2 (FFP2) respirators.

Polymers under Ionizing Radiations: the Specificity of Swift Heavy Ions

Autor: Muriel Ferry, Emmanuel Balanzat, Stéphane Esnouf, Yvette Ngono-Ravache

Publikováno v: EPJ Web of Conferences, Vol 115, p 02003 (2016)

Compared to materials such as steel or ceramics, organic synthetic polymers are very prone to radiolysis. When submitted to ionizing radiations, molecules composing them are ionized and excited. These initial species lead to the formation of radicals
