Summary: In this study, hexagonal boron nitride (h-BN) was mixed with polylactic acid (PLA) to prepare PLA/h-BN composites. The morphology, mechanical and thermal characteristics of the composites were investigated. Thermal conductivity decreased and recovery strain decreased with increasing filler content. The amount of h-BN had a mixed effect on the recovery stress of the composite. These findings suggest that PLA/h-BN composites have potential for studying the influence of a heat-conducting filler on a shape memory effect in polylactic acid.

Summary: The biomaterial-cells interface is crucial for tissue regeneration, but there is still no clear answer to what determines cell adhesion and ECM protein synthesis. The crystallinity of semicrystalline polymers used in medicine affects their surface and bulk properties. By varying the molecular weight and annealing procedure of polycaprolactone (PCL), the researchers were able to change its crystallinity. Differences in substrate crystallinity were observed through measurements of surface free energy. The water contact angle was also analyzed to determine surface wettability, which was crucial for protein absorption. The impact of crystallinity on dermal fibroblasts' response, including cellular proliferation and gene expression, was demonstrated.

Summary: Based on the analysis of the PubMed database, it was found that there is a high interest in collagen for ACL graft development and an increasing interest in hybrid grafts. The development of biodegradable and nonbiodegradable grafts is relatively balanced, and there is a limited number of clinical trials. Many studies focus on specific details and fundamental science, while only a few suggest the possibility of creating healthy tissue. Grafts exhibit a wide range of mechanical properties due to polymer types and graft morphology. Most of the research is in the in vitro stage and uses non-certificated polymers, which delays the introduction of medical devices to the market. Scientific concerns and official regulations also restrict the immediate introduction of artificial grafts to the market.

Summary: In situ crosslinked materials, such as methylcellulose (MC) hydrogel, have attracted considerable interest in both scientific and industrial research. However, the slow crosslinking rate of MC alone limits its application in tissue engineering. One approach to overcome this limitation is blending MC with agarose (AGR), which accelerates the beginning of MC crosslinking. The resulting hydrogel system shows excellent mechanical and biological properties and has potential for the design of innovative scaffold/cell delivery systems in tissue engineering applications.

Summary: This paper investigates the effect of impact damage on the fatigue behavior of CF/PEEK-titanium hybrid laminates. A fatigue life model is proposed to predict the S-N curves of the laminates based on energy dissipation approach. The energy dissipation behavior of the laminates under different experimental conditions is analyzed through post-impact fatigue tests, and the correlation between impact damage and fatigue dissipation energy is determined. The validity of the proposed model is verified through fatigue tests under different stress ratios and impact energy levels.
