Global concerns over environmental issues have led to a tremendous growth in sustainable materials emerging from biobased plastics and their composites (biocomposites). This class of materials can be an alternative to traditional composite materials to reduce the carbon footprint and strain on the environment. Many studies and reviews have been focused on enhancing the mechanical performance of biocomposites with the aim for them to compete with traditional composites and expand their applications. However, the current scientific knowledge relating to the long-term durability performance of biocomposites is very limited in open access literature. Studies of the effects of different aging mechanisms when subjected to different service conditions and environments on the biocomposites' behaviours are needed. This review provides a focused discussion on the overview of the long-term durability performance and degradation behaviour under various aging environments (thermo-oxidative aging, accelerated weathering (ultraviolet aging), hydrolytic degradation, fatigue and creep, ) of the commercially important biobased-composites for the first time. Future perspectives and methods to improve the durability performance of biocomposites are also discussed in this review.

Phthalate esters (PAEs) are broadly utilized as plasticizers in industrial products, posing a significant threat to ecological security and human health. Lipase is a kind of green biocatalyst with the ability to degrade PAEs, but its application is limited due to its low stability and poor reusability. Herein, lipase from Candida rugosa (CRL) was immobilized into an organic ligand replacement MOFs (MAF-507) and cysteine modification and glutaraldehyde cross-linking were simultaneously performed to synthesize immobilized lipase (Cys-CRL@GA@MAF-507) using a one-pot method.

This study aimed to develop polyvinyl alcohol (PVA) and kappa-carrageenan (κCA) biocomposite films using a Pickering emulsion technique for wound care applications. Juniper essential oil and modified sepiolite were incorporated to enhance functionality, with films prepared via solvent casting and characterized for structural, thermal, and mechanical properties. The PCOS-2 film exhibited the highest mechanical performance, with Young's modulus of 6.

Introduction: The use of technology in direct anterior approach (DAA) total hip arthroplasty (THA) is expanding. Although the use of computer-navigation (CN-THA) and robotics (RA-THA) has previously demonstrated improved component positioning, it is important to understand whether its use is associated with differences in intraoperative complications or early return to the operating room when compared to fluoroscopy-only (manual-THA) DAA THA.
Methods: 3433 DAA THAs (226 RA-THA, 1007 CN-THA, 2200 manual-THA) performed at a single institution were retrospectively reviewed.

This study explores the impact of three bioadditives derived from Alfalfa-biomass, bio-ashes, and lyophilisates-on natural rubber composites, with a primary focus on the anti-aging properties of lyophilisates. Composite samples were prepared by incorporating these bioadditives into natural rubber and analyzed using various characterization techniques to evaluate mechanical, thermal, aging, and surface properties. The results highlight the promising anti-aging effects of lyophilisates, significantly enhancing the aging resistance of natural rubber.

Volumetric muscle loss (VML) is a serious problem in healthcare that requires innovative solutions. Collagen and its derivatives are promising biomaterials for muscle tissue replacement due to their high biocompatibility, biodegradability, and lack of toxicity. This review comprehensively discusses collagen from various sources, its structural characteristics, cross-linking methods to obtain hydrogels, and approaches to incorporating various therapeutic molecules to create a biocomposite system with controlled release.
