Summary: This study presents a simple and alternative organic synthesis pathway for obtaining sebacic acid, a valuable dicarboxylic acid, from castor oil. The purification of castor oil methyl esters is carried out to obtain the starting material, methyl ester of ricinoleic acid. The ricinoleic acid methyl ester is then subjected to various reactions, including oxidation, isomerization, dihydroxylation, oxidative cleavage, and methylation, to ultimately obtain sebacic acid.

Summary: Copolyesters based on FDCA have gained attention due to their superior gas barrier properties and biodegradability. This study assessed the influence of aliphatic diol segmental lengths on the properties of FDCA-based copolyesters. It was found that increasing diol segmental lengths resulted in decreased glass transition temperature and a zig-zag variation in melting temperature. Furthermore, the copolyesters exhibited good mechanical properties, gas barrier properties, and rapid biodegradability.

Summary: Due to its superior tensile strength, biodegradability, and biocompatibility, poly(lactic acid) (PLA) has become a growth-oriented biodegradable material. However, its poor ductility has limited its practical applications. To address this, ductile blends were prepared by melt-blending poly(butylene succinate-co-butylene 2,5-thiophenedicarboxylate) (PBSTF25) with PLA, which significantly improved the ductility of PLA. The addition of PBSTF25 promoted cold crystallization and stretch-induced crystallization of PLA, and the resulting blends exhibited improved ductility and processing properties. The toughening effect of PBSTF25 was found to be better than that of poly(butylene succinate).

Summary: The study synthesized three kinds of aliphatic waterborne unsaturated polyesters with different compositions by melt polycondensation, and found that polyesters containing different unsaturated segment showed obvious differences in cross-linked density, mechanical properties and biodegradation rate after further cured into films. The polyesters with unsaturated double bonds in the side chain exhibited the highest cross-linking density and degradation rate, which was attributed to selective degradation of C-S-C bonds by glutathione and secondary degradation of ester bonds by lipase.

Summary: This study reports the synthesis of a terpolymer with different monomer feeding ratios for biodegradable medical implants to improve their degradation and mechanical properties. The results show that increasing the glycolide content in the terpolymer can enhance its degradation rate, allowing for a balance between the degradation rate and the body's lesion healing rate by adjusting the glycolide ratio in the terpolymer.

Summary: The Mg-6.0Zn-1.0Nd-0.5Zr (ZNdK610) alloy exhibits superior tensile properties and anti-biodegradability compared to the ZK60 alloy, attributed to refined grains and the formation of new intermetallic phases in the microstructure. The tensile strengths of ZNdK610 reach 388 MPa (ultimate tensile strength, UTS) and 356 MPa (yield strength, YS), showing significantly improved anti-biodegradability.

Summary: A bio-based plasticizer, A-CAE, was successfully synthesized from ricinoleic acid through esterification, epoxidation, and acetylation. Its plasticizing properties were tested and compared with commercial plasticizers DOTP and ATBC in PVC films. The results showed that A-CAE exhibited excellent compatibility with PVC, high elongation at break, and transparency, indicating its great potential as a plasticizer for PVC.

Summary: The demand for sustainable development has led to increasing attention in biobased polyesters due to their adjustable thermal and mechanical properties and biodegradability. In this study, a list of novel aromatic-aliphatic poly(alkylene adipate-co-thiophenedicarboxylate) (PAATh) copolyesters was synthesized using a novel bioderived aromatic diacid. These copolyesters showed high thermal stability, excellent tensile strength, and superior gas barrier performances. The biodegradability of PAAThs was fully evaluated, and the effect of diol components on enzymatic degradation was revealed by computational analysis. This study provides insights into the development of promising substitutes for commercial biodegradable polyesters and sheds light on their complicated degradation mechanisms.

Summary: This paper conducts an in-depth analysis of IPMC as sensors, revealing a correlation between IPMC metal content and water uptake. The study shows that introducing mass to the end of a high-frequency IPMC sensor improves sensing behavior, while low-frequency IPMC sensors exhibit a reverse trend. Gold coating on a high-frequency IPMC sensor decreases resonant frequency, and pre-bending with optimal mass loading benefits sensing voltage on the Au-coated HFI sensor.

Summary: Transition metal substituted Co3O4-ZrO(2) catalysts (NiCZ, CuCZ and FeCZ) were synthesized by PEG assisted sonochemical synthesis and showed excellent catalytic activity and stability for lean methane combustion. The presence of SO(2) in the reactant feed significantly inhibited the catalytic activity, although FeCZ exhibited superior performance compared to NiCZ and CuCZ. Characterization studies using XRD, XPS, TEM and H-2-TPR revealed structural and reducibility properties of the catalysts.

Summary: The study demonstrates that an amorphous metal based on palladium shows substantial thrombogenic resistance compared to a state-of-the-art titanium alloy, reducing platelet activation and delaying fibrin formation in contact with human whole blood. However, it also promotes platelet spreading, challenging the traditional view that spreading equals activation. Mechanistic analysis reveals changes in adhered fibrinogen and modified alpha(IIb)beta(3) integrin expression as factors underlying the superior performance of Pd glass in direct blood-contact applications. Structural, thermophysical, and physicochemical characterization further supports the potential of Pd-based glass as a promising bulk material for blood-contacting devices without the need for additional coatings.

Summary: By using a light-responsive hydrogel as an actuating substrate, we investigated the response of myoblast cells to mechanical actuation and found that actuation enhances cell proliferation and migration while reducing collagen and fibronectin deposition. These findings highlight the importance of controlling the actuation time and amplitude for myoblast proliferation and mechanotransduction.
