Polyetheretherketone bioactivity induced by farringtonite

open access: yesScientific Reports
AbstractPolyetheretherketone (PEEK) is considered as an excellent biomaterial for bone grafting and connective tissue replacement. The clinical potential is, however, limited by its bioinertness, poor osteoconduction, and weak antibacterial activity.

Morphological, Thermal, and Mechanical Analysis of 3D Printed Polyetherketoneketone (PEKK) and PEKK‐Hydroxyapatite Composites: Establishing the Reference Enthalpy of Fusion for Crystalline PEKK 7003

open access: yesMacromolecular Materials and Engineering, Volume 311, Issue 2, February 2026.
Using thermal analysis and X‐ray diffraction on 3D‐printed PEKK and PEKK‐HA composites, the authors determine a material‐specific heat of fusion for fully crystalline PEKK 7003 (155.24 ± 5.39 J/g). The updated benchmark improves agreement between analytical methods and enables more reliable links between processing, structure, and performance in 3D ...

First experimental characterization of a low‐pressure nitrogen filled parallel‐plate ionization chamber for UHDP electron beam dosimetry

open access: yesMedical Physics, Volume 53, Issue 2, February 2026.
Abstract Background Ultra‐high dose‐per‐pulse (UHDP) dosimetry remains a key challenge in FLASH radiotherapy. Conventional ionization chambers (ICs) experience severe electric field perturbations under UHDP conditions due to high charge densities, leading to severe recombination.
