“…The first result is not surprising as the temperature used to sterilize medical materials (134 °C) is much lower than the glass transition and crystallization temperatures of the tested alloy (394 °C and 432 °C, respectively). Concerning the sterilization by gamma irradiation, our result is consistent with previous studies highlighting no effect of gamma rays on the mechanical [39], electrical [40] and magnetic [41] properties of several BMG materials. This proves that sterilization can be performed on Ti 40 Zr 10 Cu 36 Pd 14 alloy without any deleterious influences regarding their amorphous nature and their future use as implants.…”

Ti40Zr10Cu36Pd14 Bulk Metallic Glass (BMG) appears very attractive for future biomedical applications thanks to its high glass forming ability, the absence of toxic elements such as Ni, Al or Be and its good mechanical properties. For the first time, a complete and exhaustive characterization of a unique batch of this glassy alloy was performed, together with ISO standard mechanical tests on machined implant-abutment assemblies. The results were compared to the benchmark Ti-6Al-4V ELI (Extra-Low-Interstitial) to assess its potential in dental implantology. The thermal stability, corrosion and sterilization resistance, cytocompatibility and mechanical properties were measured on samples with a simple geometry, but also on implant-abutment assemblies’ prototypes. Results show that the glassy alloy exhibits a quite high thermal stability, with a temperature range of 38 °C between the glass transition and crystallization, a compressive strength of 2 GPa, a certain plastic deformation (0.7%), a hardness of 5.5 GPa and a toughness of 56 MPa.√m. Moreover, the alloy shows a relatively lower Young’s modulus (96 GPa) than the Ti-6Al-4V alloy (110–115 GPa), which is beneficial to limit bone stress shielding. The BMG shows a satisfactory cytocompatibility, a high resistance to sterilization and a good corrosion resistance (corrosion potential of −0.07 V/SCE and corrosion current density of 6.0 nA/cm2), which may ensure its use as a biomaterial. Tests on dental implants reveal a load to failure 1.5-times higher than that of Ti-6Al-4V and a comparable fatigue limit. Moreover, implants could be machined and sandblasted by methods usually conducted for titanium implants, without significant degradation of their amorphous nature. All these properties place this metallic glass among a promising class of materials for mechanically-challenging applications such as dental implants.

“…This means that PBS has received equal attention to that given to other biodegradable polymers such as poly(lactic acid) (PLA) and poly(hydroxyl butyrate) (PHB), which are also derived from renewable resources. In comparison to PLA and PHB, PBS is relatively ductile and flexible in nature, with low rigidity, which has made it more suitable for various applications [4][5][6][7][8].…”

The present work deals with the utilization of oil palm mesocarp fibre (OPMF) and poly(butylene succinate) (PBS) to produce cost-effective biodegradable materials. The biocomposite was prepared from OPMF and PBS at a weight ratio of 70:30 via a melt blending technique without addition of any additive. This biocomposite showed relatively low tensile and water resistance properties. As a consequence, it was subjected to electron beam irradiation (EBI) treatment under various irradiation dosages ranging from 5-25 kGy, aiming at improving both its tensile properties and its water resistance. The results indicated that the biocomposite irradiated with 25 kGy of applied dosage showed a considerable improvement of 50% in tensile strength, 780% in tensile modulus and 38% in elongation at break. The water absorption and thickness swelling of the biocomposites were reduced after EBI treatment. The scanning electron microscopy showed improvement of the interfacial adhesion between OPMF and PBS after EBI treatment.
