Head form variation in mountain newts of the genus Calotriton (Amphibia, Salamandridae) in a phylogeographic context

open access: yesZoologica Scripta, Volume 54, Issue 4, Page 473-486, July 2025.
Abstract Relief has a profound impact on the genetic structure of species. While the geographic ordination of genetic variation is assessed in many mountain species, the factors involved in phenotypic differentiation and its congruence with phylogeographic history have been largely underexplored. This is the case of the genus Calotriton.

In Situ Polymerization of Barium Hexaferrite Ferrofluids for Poly(Ethylene) Succinate Magnetic Nanoparticle Composites

open access: yesJournal of Applied Polymer Science, Volume 142, Issue 23, June 15, 2025.
ABSTRACT The integration of hard magnetic barium hexaferrite (BHF) nanoplatelets into a dense poly(ethylene succinate) (PES) polyester matrix produces an exciting biodegradable thermoplastic magnetic polymer nanocomposite. In this work, scandium‐substituted BHF nanoplatelets are grown and stabilized in hexadecyltrimethylammonium bromide (CTAB ...
