In this research, ZrC coatings are evaluated against various counterprobes at the microscale using novel super‐stiff atomic force microscopy cantilevers. The chemical composition of the coating is shown to be an important factor influencing coating hardness and Young's modulus, while surface roughness, counterprobe hardness, and surface energy are the ...

W‐Based Thin Film Metallic Glasses Doped with Ni, Zr, and B for Industrial Applications
This work is the first to deal with a comprehensive comparison of two metallic glass systems, W–Zr–B and W–Ni–B, in terms of their suitability for specific industrial applications. Their mechanical and tribological properties are compared and discussed in combination with structural homogeneity on different types of technically relevant substrates and ...

No More Bricks in the Wall: Adopting Healthy Lifestyles through Physical Education Classes [PDF]
Despite the multiple benefits associated with practicing physical activity regularly, less than 20% of the population do it on a daily basis. Physical education classes could contribute, during childhood and adolescence, to consolidating adherence to ...

Powder Metallurgy Preparation of Metastable β Ti–Cr–Ge Alloys for Medical Applications
This study develops metastable β Ti–Cr–Ge alloys using powder metallurgy for biomedical implants. The Ti–10Cr–2Ge alloy exhibits superior mechanical performance with high yield strength (>1100 MPa), low Young's modulus (<85 GPa), and excellent strain hardening behavior.

3D Bioprinting of Thick Adipose Tissues with Integrated Vascular Hierarchies
An advanced 3D bioprinting technique is used here to create thick adipose tissues with a central, vessel and extensive branching. The construct is made using alginate, gelatin and collagen‐based bioinks. Flow through the complex vessel network is demonstrated as well as its successful integration with a femoral artery following implantation in a rat ...

The formate pseudo‐halide anion is strategically introduced at the buried interface to stabilize the intermediate phases formed during perovskite crystallization. The controlled crystallization enhances crystallinity and alleviates tensile strain, eliminating residual PbI2 near the buried interface.
