Summary: In this study, an innovative and environmentally friendly method for preparing nanoporous silver materials using femtosecond laser was demonstrated. The yield strength of the nanoporous silver materials was found to increase monotonously with the increase of laser power, attributed to the decline of grain size and rise of relative density. The research not only proposes a new fabrication method for nanoporous silver materials, but also reveals the influence of fs laser power on their yield strength.

Summary: Cellulose fibers are difficult to characterize accurately due to their irregular shape and anisotropic material response. Traditional single fiber tensile testing has limitations, but nanoindentation can provide elastic material constants for individual fibers and enable in-situ measurement in paper sheets, capturing the entire industrial process history. Longitudinal modulus is comparable to traditional methods for larger indents, but with increased scatter as the indentation size decreases.

Summary: The mechanical properties of drug molecules are important for their processing into finished products. This study focuses on the mechanical anisotropy in two polymorphs of ambrisentan. Nanoindentation experiments showed that form I has higher hardness and elastic modulus compared to form II. The differences in mechanical properties were explained by differences in crystal structure and intermolecular interactions. Overall, form II exhibited higher plasticity and tabletability than form I. This study highlights the importance of crystal structure in determining the mechanical performance of drug crystals.

Summary: The internal mechanism of how maceral and temperature control the mechanical properties of in situ coal has not been established so far. This study aims to discover the control mechanism of macerals and temperature on the mechanical properties of in situ coal. By linking the macroscopic and microscopic mechanical properties, it was found that the hardness and elastic modulus of macerals adhere to a specific order, and varying temperatures do not transform this order. The content increase of liptinite, vitrinite, and inertinite affects the hardness and elastic modulus of the whole coal differently. Temperature alters the mechanical properties of in situ coal through macerals as an intermediary, and there is a watershed in the effect of temperature on coal mechanical properties.

Summary: The effect of heat treatment on the structure and mechanical properties of Co-Fe-Cr-Si-B/Fe-Cr-B/Fe-Ni-B amorphous alloys has been systematically studied. It is shown that the transition to a two-phase amorphous-nanocrystalline state upon annealing leads to substantial strengthening of the alloys and a partial recovery of their plasticity. The phenomenon of plasticization in amorphous alloys is due to the effective retardation of cracks on nanoparticles.

Summary: In this study, the Fe22Co22Ni22Ti22Al12 alloy coating was fabricated by magnetron sputtering, and its microstructure was characterized using techniques such as nanoindentation and transmission electron microscopy. The results showed that the crystal structure of the target transformed into an amorphous phase in the coating during sputtering, and re-crystallization occurred during the process of indentation. These findings revealed the reasons for the good mechanical properties of the Fe22Co22Ni22Ti22Al12 alloy.

Summary: The effect of temperature on the tensile strength of perforated TC4 alloy was investigated. It was found that the tensile strength of all types of alloy specimens decreased with increasing temperature, and most types of specimens also showed a decrease in elastic modulus. The tensile strength of the perforated specimen was lower than that of the solid specimen at room temperature, but higher at 500 degrees C. The existence of prefabricated holes in the specimens helped dissipate thermal stress and maintain the integrity of the micro-hole structure, resulting in higher tensile strength and structural stiffness at elevated temperatures.

Summary: Investigating the shock-induced phase transition in equiatomic FeNiCrCoCu HEA, this study reveals that the transition is more likely to occur along specific crystallographic directions and at certain shock velocities. With an increase in shock velocity, a shift in deformation mechanism from dislocation-dominated to phase-transition-dominated is observed, contributing to the weakening of shock wave and damage attenuation.

Summary: This study investigates the depth-dependent mechanical properties of Zr-based bulk metallic glasses using the depth-sensitive nanoindentation technique. The results show that the surface hardness and elastic modulus increase, while fracture toughness decreases with decreasing indentation depth.

Summary: The nanoindentation creep behavior and underlying mechanisms of nanocrystalline Ni and Ni-Fe alloy were studied using a new testing method. The continuous creep strain rate and apparent activation volume data were obtained using the continuous stiffness measurement (CSM) technique. The effects of loading rate and stacking fault energy on the nanoindentation creep behavior were analyzed. The study found that the Ni-Fe alloy showed higher creep resistance in the transient regime but lower creep resistance in the steady-state regime compared to Ni. The contact stiffness data obtained by CSM technique can be used to determine the creep stress data.

Summary: The creep properties of articular cartilage in different regions were experimentally determined, and a full regional creep map was constructed. The correlation between microstructures and creep properties of cartilage in different regions was revealed. A three-parameter model was established to describe the creep velocity-displacement response of cartilage. Raman spectra showed a positive correlation between proteoglycan content and creep properties, and diverse residual stresses were indicated by Raman shift in different microregions. These findings contribute to a better understanding of the creep-dependent damage mechanism of cartilage and the development of artificial cartilage materials.

Summary: Clarifying the mechanisms of consecutive droplet rebound can provide scientific inspiration for regulating the dynamic wettability of superhydrophobic surfaces, with potential applications in efficient heat control and active anti-icing. This study introduces a novel golden section design criterion that regulates the number of droplet rebounds based on structure spacing, challenging conventional knowledge. The researchers observed the remarkable phenomenon of droplet trampoline, with droplets rebounding continuously for 17 times on a metal-based surface. The experimental results reveal a close correlation between the droplet rebound number and the Weber number, and propose quantitative formulas to predict the rebound number and clarify the coupling effect of structure spacing and the Weber number on rebound mechanisms.
