Sputtering based fabrication routes are particularly promising whenever high purity and monodisperse particles are required. This work establishes quantitative synthesis-structure relations for Cu-nanoparticles (diameter &lt; 10 nm), synthesized through magnetron sputtering inert gas condensation and high-power impulse hollow cathode sputtering. The two deposition methods are compared in terms of nanoparticle deposition rate, morphology and size distribution. While magnetron sputtering inert gas condensation with quadrupole mass spectrometry offers excellent control of the size distribution of single-crystal particles, high-power impulse hollow cathode sputtering enables deposition of polycrystalline nanoparticles at higher deposition rates with more efficient target utilization. Consequently, porous, randomly assembled nanoparticle-based films of up to 1.5 µm thickness have been fabricated. Stabilization of these structures via atomic layer deposition (ALD-Al₂O₃, thickness up to 20 nm) is demonstrated through electron microscopy and nanoscratching, linking nanoscale structure to macroscale mechanical performance. While ALD encapsulation at 120°C does not change the Cu microstructure, the scratch resistance of the films improves with increasing encapsulation layer thickness.

The recurrence rate of hernias is over 50%, increasing morbidity. Research is ongoing to identify a suitable solution to repair large defects because common prosthesis does not match the mechanical properties of the native tissue. This pilot study aims to evaluate a new non-biodegradable thermoplastic polyurethane elastomer (TPU) bilayer patch. Its mechanical properties may be better suited to facilitate growth from childhood to adulthood. Its structure comprises a fibrous layer that promotes cell colonization and integration, and a smooth film layer that prevents cell adhesion. In vitro studies showed that both fibroblasts and myoblasts colonized the fibrous layers efficiently when they were optimized with an adhesive polydopamine (PDA) film and a collagen I (Coll I) coating. This facilitated early colonization, increased proliferation and cell spreading. New materials, whether functionalized or not, did not induce inflammation. Subsequent in vivo studies in rats showed significant cell integration in TPU patches without prosthetic debris. In contrast, phagocytosed prosthetic debris were detected in rats implanted with the reference material expanded polytetrafluoroethylene (e-PTFE).

Here, we present a robust design strategy for producing polar columnar LCs based on nonsymmetric π-conjugated 1,3,4-oxadiazole-derived bent-core polycatenars. The materials feature three alkoxy chains at one end and a single chain at the other, with the latter incorporating an azobenzene moiety that is either nonfluorinated or fluorinated to varying degrees. Increasing the degree of fluorination directs the molecular aggregation into novel modes of self-assembled columnar structures, leading to polar columnar phases. All phases could be perfectly aligned under an electric field due to the induced dielectric polarization from the oxadiazole ring. Notably, while nonfluorinated materials fail to form gels in organic solvents at low concentrations, their fluorinated counterparts exhibit exceptional gelation capabilities at concentrations below 1% weight, classifying them as supergelators. This behavior is due to enhanced π–π interactions and directed aggregation facilitated by aromatic core fluorination. Additionally, all materials exhibit reversible <i>trans-cis</i> photoisomerization upon light irradiation, both in the bulk state and in solution.
