A Mixed Covalent–Supramolecular Interpenetrated Copper–Phosphonate Network

Zeitschrift für anorganische und allgemeine Chemie, Volume 652, Issue 11, 16 July 2026.
Zigzag Cu–bisphosphonate double strands are connected by dipyridyl linkers to two‐dimensional layers which are organized via hydrogen bonds into a three‐dimensional, two‐fold interpenetrated hydrogen‐bonded framework. A novel copper‐based coordination network [Cu(1,4‐DPB)(H2NBP)] was synthesized via a hydrothermal process using 1,4‐di(pyridin‐4‐yl ...

Experimental Evaluation of 100Cr6 Steel Microindented Surfaces Under Lubricated Nonconformal Point Contacts

Advanced Engineering Materials, Volume 28, Issue 13, 8 July 2026.
The tribological behavior of 100Cr6 steel spheres textured via Vickers microindentation is evaluated under lubricated sliding by varying both dimple size and density. Fine and dense textures significantly reduce friction across all lubrication regimes, while large dimples increase it.

Direct Metal Deposition of Graphene–Ti28Nb35.4Zr Matrix Composites With Enhanced Mechanical, Corrosion, and Biocompatibility Properties for Bone Implants

Advanced Engineering Materials, Volume 28, Issue 13, 8 July 2026.
Graphene nanoplatelet (0.1 wt.%) reinforcement significantly enhances the performance of β Ti‐28Nb‐35.4Zr alloy. Grain refinement, reduced water contact angle, and improved surface characteristics promote osteoblast adhesion and complete surface coverage after 7 days.

Resolving the Cu(bdc) Conundrum: Identifying Non‐Porous Packing of Prototypical Coordination‐Network Thin Films Combining Advanced Diffraction Techniques and Computational Modelling

Advanced Functional Materials, Volume 36, Issue 55, 9 July 2026.
Solution‐processed Cu(bdc) forms prototypical MOF thin films for which a multitude of not fully satisfactory structural models have been suggested. Combining rotating grazing‐incidence diffraction and X‐ray reflectivity on two complementary samples with density‐functional theory, we first discard the previously suggested models and then identify a non ...

Review of Thermally Activated Twisted Coiled Polymer Actuators: A Materials Science Perspective

Advanced Functional Materials, Volume 36, Issue 58, 20 July 2026.
Thermally activated twisted and coiled polymer actuators (TCPAs) combine lightweight design, large deformation, and scalable fabrication for soft robotic and wearable applications. This review connects polymer structure, processing history, helix geometry, and thermomechanical characterization to actuator performance, highlighting current challenges in
