Summary: The study of surface-modified system F4-TCNQ/EG/SiC using X-ray photoelectron spectroscopy (XPS) and angle-resolved polarized Raman spectroscopy (ARPRS) showed that the bonding of deposited F4-TCNQ molecules depends on their concentration. Charge transfer from graphene to fluorine is evident only at sub-monolayer concentrations, with a corresponding change in bond character coupled with a change in molecular orientation. Raman spectroscopy also revealed a significant degree of molecular stacking above the monolayer concentration.

Summary: The study reports direct monitoring of the evolution of DP and FI under strain in layered MoS2 using circularly polarized Raman spectroscopy, and finds the relative proportions of DP and FI can be evaluated by the circular polarization ratio of the E-2g(1) mode. It further demonstrates that the strain control of DP and FI in MoS2 is dominated by the excitonic effect, and the method can be extended to other 2D semiconductors for manipulating exciton-phonon couplings by strain.

Summary: This study compared the biomechanical effects of bionic trabecular metal and titanium jumbo cups for acetabular bone defect revision. Finite element analysis showed that bionic tantalum jumbo cups had superior stress distribution and higher relative micromotion compared to titanium jumbo cups. Therefore, we recommend the use of trabecular metal cups for acetabular reconstruction.

Summary: This study investigates the modulation of birefringence on the angle-resolved polarized Raman spectroscopy (ARPRS) response and the intrinsic response using transparent birefringent crystal alpha-MoO3. The anomalous ARPRS responses in alpha-MoO3 can be well explained by the birefringence-induced Raman selection rules. The thickness-dependent study shows that birefringence modulates the ARPRS response to create an interference pattern.

Summary: Polarized and non-polarized Raman spectroscopy can be useful tools for determining crystal plane orientation, exemplified with ZnO. The methodology involves studying the polarization direction dependences of Raman peaks and using symmetry of modes to derive a model for determining the relation between polar and non-polar crystal orientation. This approach allows for analysis with non-polarized light sources and potential use in dimensions smaller than the diffraction limit.

Summary: Fully cured epoxy resins are typically brittle materials, however, cured epoxy fibers show exceptional mechanical behavior, including yielding followed by large deformation, and very high strength, toughness, and modulus. These properties intensify as the fiber diameter decreases, but the microstructural origin of this behavior remains fully determined.

Summary: A novel strategy is proposed to analyze the orientation of cellulose microfibrils without prior knowledge. The direction of cellulose microfibrils can be determined by the polarization-dependent Raman signal intensity. This strategy was successfully used to study variations in molecular orientation in the cell wall of balsa wood.

Summary: Black phosphorus, as an anisotropic material, has unique optoelectronic properties. This research proposes a new method to identify the crystalline orientation of black phosphorus by comprehensively analyzing the A(g)(1) and A(g)(2) modes under orthogonal polarization configuration, and experimental results demonstrate the effectiveness of this method for different thicknesses of black phosphorus.

Summary: Polarized Raman spectroscopy is used to determine and validate the crystallographic orientations of Zinc blend crystals. Two crystals of GaAs and ZnTe oriented along (112) are used in the study. Different angles of in-plane rotation and polarization are achieved by fixing the excitation laser polarization and rotating the sample. Raman spectroscopy is used to study crystallographic plane identification by measuring the Raman scattered intensity and fitting it with a transformation matrix relation.

Summary: This study investigated the relationship between the microscale compressive mechanical properties of bone and mineralized collagen fibril orientation, finding a strong dependence of compressive micromechanical properties on fibril orientation with high anisotropy. It also revealed a transition from softening to hardening behavior at approximately 50 degrees. The combination of methods used provides a reliable way to determine structure-property relationships at the microscale, offering insights into bone quality assessment.

Summary: This study used a 3D-transient elastohydrodynamic model to investigate the interaction between material stiffness and film thickness in total hip arthroplasty material couples. The model showed that the average and central film thickness of PCU was higher than that of UHMWPE, but the distribution of film thickness was asymmetric and the minimum film thickness occurred outside of the central axis. While the overall film thickness of PCU was higher than UHMWPE, the minimum film thickness of PCU was lower for most of the gait cycle, indicating a more nuanced interaction between bearing material stiffness and film thickness.

Summary: By comparing CT-based methods with marker-based RSA in 10 patients who underwent total hip replacement, it was found that CTMA had comparable precision to RSA. The CT radiation doses were slightly higher than RSA doses, but still at a considerably low effective dose.

Summary: This study investigates the feasibility of using injection molding to manufacture acetabular liners (AL) with new generation UHMWPE biomaterial and presents the key biomechanical response analysis of these prototypes. The results demonstrate the influence of subject weight on micro-strain generation and distribution in the acetabulum fossa and the increase in von Mises stress in AL with subject weight.

Summary: This study aimed to investigate the level and probability of bacterial contamination on scrub suits worn by medical personnel inside and/or outside the operating room (OR) area. The study found that scrub suits worn outside the OR area had a higher level of bacterial contamination compared to those worn inside. Additionally, the probability of contamination involving coagulase-negative staphylococci (CNS), a primary cause of periprosthetic joint infection (PJI), significantly increased after a long-time departure from the OR area.

Summary: This study aimed to investigate whether using a thicker liner in vitamin-E-diffused HXLPE could enhance in vivo creep and wear performance. The 7-year follow-up results showed no significant difference in wear rates between different liner thicknesses, but the thinner liner had higher strain. Further long-term follow-up is needed to evaluate the incidence of wear and osteolysis.
