Pygmy Dipol Resonances as a Manifestation of the Structure of the Neutron-Rich Nuclei

, 2003
Dipole excitations in neutron-rich nuclei below the neutron threshold are investigated. The method is based on Hartree-Fock-Bogoliubov (HFB) and Quasiparticle-Phonon Model (QPM) theory. Of our special interest are the properties of the low-lying 1- Pygmy

Dual‐Functional 3D‐Printed Porous Titanium–Hydrogel Composite Scaffold With Mg2+ and ZIF‐8 Release for Enhanced Bone Regeneration and Bacterial Inhibition

Small Structures, Volume 7, Issue 3, March 2026.
This study developed a dual‐functional 3D‐printed porous titanium–hydrogel composite scaffold loaded with Mg2+ and zeolitic imidazolate framework‐8 (ZIF‐8) nanoparticles. The scaffold enhanced bone regeneration through the synergistic effect of Mg2+ and ZIF‐8, and inhibited bacterial growth via the synergistic action of its hydrogel matrix and ZIF‐8 ...
