Summary: The Carbon dioxide (CO2)-assisted polymer compression method is used to plasticize and crimp polymer fibers. The degree of plasticization is crucial for this method. In this study, heat treatment was applied to obtain fibers with different degrees of crystallinity. The compression degree and hardness were compared using two types of sheets. The Young's modulus of porous polymers in the presence of CO2 varies significantly with slight differences in crystallinity, highlighting the importance of low crystallinity for polymer plasticization by CO2.

Summary: Stress shielding occurs due to the disparity in stiffness between bone and implant materials, leading to bone resorption and loosening, and ultimately causing implantation failure. The use of a porous structure design can achieve a low Young's modulus that matches that of human bone, addressing this issue. In this study, a TiZrNbTa/Ti titanium matrix composite (TMC) with high strength and ductility was used as scaffold material, and a novel space holder (MgO particles) was employed to withstand high-temperature sintering. The resulting porous TiZrNbTa/Ti material demonstrated higher strength and a matching Young's modulus, showing promise for clinical application.

Summary: Titanium alloys are widely used as bone implants, but their long-term clinical success is compromised by challenges such as the stress shielding effect. In this study, non-toxic alloying elements zirconium (Zr) and molybdenum (Mo) were added to titanium to produce Ti-Mo-Zr alloys. The addition of Zr and Mo improved the mechanical properties of the alloys and showed higher microhardness and compressive yield strength. Ti-12Mo-10Zr exhibited the lowest Young's modulus and the alloys demonstrated good cytocompatibility and osteointegration, making Ti-12Mo-10Zr a promising material for bone repair.

Summary: In this study, the influence of oxygen content on the microstructure and mechanical properties of Ti-Nb alloys was evaluated. The results showed that increasing oxygen content slightly affected the thickness of alpha plates and beta-transus, but improved hardness and compressive yield stress. Solid-solution strengthening by Nb and oxygen, along with microstructural refinement by Nb addition, were responsible for these improvements.

Summary: Nanoindentation is an optimal technique for measuring thin film mechanical properties, but it is not suitable for probing the nanoscale properties of polymers due to their time-dependent response to loading. In this study, a nanoindentation technique is presented that analyzes the time-dependent response of poly(3-hexylthiophene) under both constant rate loading and step loading. The Young's relaxation modulus of poly(3-hexylthiophene) is extracted by determining viscoelastic functions.

Summary: This work investigated the formation of a hybrid composite coating composed of strontium-doped hydroxyapatite (HA) and graphene oxide (GO) on the surface of beta-type TiNbTaZr (TNTZ) alloy using a green hydrothermal method. The addition of GO resulted in a decrease in the crystallinity of the HA/Sr coating and the formation of dense homogeneous nanocrystalline structures. Electrochemical measurements demonstrated that the composite coating prepared from a solution with 4.5 wt% GO exhibited the lowest corrosion density and the highest polarization resistance, indicating its potential as a candidate material in orthopedic applications.

Summary: The study found that different titanium alloys exhibit different wear modes against zirconia, resulting in varying dependence on sliding distance. The wear loss of Ti64 increases with sliding distance, while TNTZ does not necessarily show the same pattern. The different roles of wear debris in the wear process lead to varying effects on wear for each titanium alloy.

Summary: This study investigated the influence of high-pressure torsion (HPT) processing parameters and solution treatment (ST) on the corrosion and tribocorrosion behavior of CoCrMo (CCM) alloys for potential biomedical applications. The corrosion behavior was evaluated using potentiodynamic scanning and electrochemical impedance spectroscopy tests, while tribocorrosion tests were conducted in a reciprocating ball-on-plate tribometer. The results showed that HPT and ST processes had minimal effect on the corrosion resistance of the samples, but ST-treated samples exhibited higher material loss during sliding in standard phosphate-buffered saline at body temperature compared to HPT-treated samples.

Summary: This paper introduces the concept and fabrication process of titanium alloy rods for spinal fixation. The rod for the lower side of the lumbar vertebra is strengthened, while the rod for the upper side has low stiffness. Finite element analysis reveals that a rod with partially lowered Young's modulus has higher flexibility and fixity. Ti-29Nb-13Ta-4.6Zr alloys with different oxygen contents were used to fabricate rods with different Young's moduli, and the aging and induction heating treatments were utilized to obtain desired properties.
