Enabling Real‐Time, Non‐Ionizing 3D Imaging of Implantable Magnetic Cements Using Magnetic Particle Imaging

Advanced Materials Interfaces, EarlyView.
This study reports the first implantable resin cement capable of orientation‐sensitive Magnetic Particle Imaging (MPI). By coating the cement with an ultrathin iron film, the authors achieve a strong, angle‐dependent MPI signal that enables non‐ionizing, real‐time tracking of both implant position and orientation, opening new possibilities for safe ...

Charge Transfer States in Donor–Acceptor Bulk‐Heterojunctions as Triplet–Triplet Annihilation Sensitizer for Solid‐State Photon Upconversion

Advanced Materials Interfaces, EarlyView.
A near‐infrared photosensitizer that facilitates efficient solid‐state photon upconversion by recycling triplets formed within a fullerene‐based donor–acceptor bulk‐heterojunction system is demonstrated. Spectroscopic investigations reveal that the energy of photogenerated charge transfer states of triplet character (3CT) is subsequently transferred to

Phonon Engineering in Ultrathin Sn Films

Advanced Materials Interfaces, EarlyView.
When embedded in multilayer structures, ultrathin Sn layers demonstrate strongly modified vibrational density of states (VDOS). This allows engineering a drastic increase of the Lamb‐Mössbauer factor fLM$f_{\text{LM}}$ and thereby of the cross‐section for coherent excitation of the ultrasharp nuclear resonance of 119Sn$^{119}{\rm Sn}$. This enables the

Development of Laterally Graded X‐Ray Multilayer Optics

Advanced Materials Technologies, EarlyView.
This work presents the development of laterally graded X‐ray multilayer optics with both constant and variable lateral gradients. By precisely controlling substrate speed profiles and mask design, these multilayers achieve highly accurate lateral gradients and excellent sagittal thickness uniformity, making them ideal for spectroscopy application at ...
