A novel circumscription and classification for Neurolaeneae (Asteraceae)

open access: yesTAXON, EarlyView.
Abstract Neurolaeneae (Asteraceae) have a complicated taxonomic history. The tribe was described in 1927, but subsequently disregarded in 1977, and later reinstated as a tribe following a large‐scale phylogenetic analysis of Asteraceae in 2002. To date, this tribe has remained poorly studied and it has never been the subject of a comprehensive ...

Radiation‐Induced Degradation in Polymeric Materials: Alterations in Physical–Chemical Properties and Their Effects on Electrical Performance of Insulation Systems

open access: yesHigh Voltage, EarlyView.
ABSTRACT This paper investigates the effects of radiation on polymeric materials used as insulation systems in electrical equipment such as cables for nuclear and particle accelerator applications. After a detailed description of the physics of radiation‐induced damage in the polymeric matrix, a comprehensive analysis of the physical–chemical and ...
