Summary: Mechanics plays a crucial role in cell function and tissue regeneration, and the mechanical detection of cell mechanics and cellular-scale microenvironments is essential for understanding cell activities affected by physical factors. This review focuses on advanced techniques and applications of cell-scale mechanical detection, including atomic force microscopy, optical tweezer, magnetic tweezer, and traction force microscopy. It also discusses the application of mechanical testing techniques to cell mechanics and tissue engineering scaffolds. The challenges and prospects in this field are highlighted, providing valuable insights into micromechanics in tissue engineering.

Summary: This study investigates the use of human hair as an organic fiber filler to reinforce rubber matrix composites. The results show that the hair filler effectively enhances the mechanical properties of the composites, with considerable improvement in elastic modulus, tensile strength, and damage tolerance. The SEM imaging confirms the satisfactory interfacial bonding between hair and rubber. Additionally, the potential application of photoacoustic microscopy for 3D reconstruction and non-destructive testing in composite materials is evaluated.

Summary: In this study, the influence of Re on the mechanical behavior of single crystal Ni-based superalloys was investigated using experiments, first-principle, and molecular dynamics methods. The distribution of Re, its effects on lattice parameter, stacking fault energy, elastic and plastic deformations at different temperatures were systematically analyzed. The results not only quantitatively revealed significant mechanisms behind the Re effect, but also provided inputs for larger scale simulation methods. The influence of Re on the long-term deformation property of single crystal Ni-based superalloys was reasonably discussed in the viewpoint of thermodynamic and dislocation dynamics based on simulation results.

Summary: New aspects of corrosion resistance/attack of Incoloy 800 H/HT in FLiNaK at 680 degrees C were studied. The effect of various impurities and their concentration on the corrosion was analyzed. Results showed that acidic or hydrated salts, the use of a GC crucible and higher concentration of additives all increased corrosion. It is crucial to avoid the presence of hydrogen after purification, as it triggers corrosion along with other substances.

Summary: Dynamic Strain Ageing (DSA) has been widely accepted as the mechanism behind the Portevin-Le Chatelier effect in ferritic steels since its proposal in the 1940's. However, its applicability to Face-Centred Cubic (FCC) alloys, including nickel-based superalloys, is still uncertain. This review compares plastic instabilities in superalloys to those in ferritic steels and discusses outstanding issues and proposed explanations for the phenomena.

Summary: To increase the ductility of alumina-forming Co-Cr-Al oxide dispersion strengthened (ODS) superalloys, Ni alloying was introduced. Four grades of Co-20Cr-15Al-xNi (x = 0, 10, 20 and 30) at.% ODS superalloys were fabricated. The addition of Ni inhibited the formation of brittle phase and facilitated ductile fracture, leading to improved strength and ductility.

Summary: This study conducted creep rupture tests on powder metallurgy superalloys with various Ta additives to further understand the effect of Ta on creep damage. The results showed that multiple crack propagation and damage mechanisms could occur under the same creep condition, and the addition of Ta could alter the size of these different fracture mode areas. However, the effects of Ta changed significantly under different creep conditions.

Summary: This review article explores the complex world of biocompatibility testing, including chemical, mechanical, and biological characterization. The researchers highlight the lack of an organized tool for selecting the appropriate biocompatibility test for implants. They propose a solution that includes a flowchart and Python code to guide stakeholders in navigating biocompatibility testing. This work bridges the gap between theory and implementation, empowering researchers in safer and more effective implant development.
