“…Polyurethanes are biocompatible, biodegradable polymers with excellent flexibility, durability and resistance. Due to their biostability, they are favourable inert materials for development of medical devices [259], vascular grafts [260], prostheses [261], heart valves [262,263], catheters [264], drug delivery and as porous scaffolds for tissue regeneration [265].…”

Biomaterials are mostly any natural and synthetic materials which are compatible from a biological point of view with the human body. Biomaterials are widely used to sustain, increase, reestablish or substitute the biological function of any injured tissue and organ from the human body. Additionally, biomaterials are uninterruptedly in contact with the human body, i.e., tissue, blood and biological fluids. For this reason, an essential feature of biomaterials is their biocompatibility. Consequently, this review summarizes the classification of different types of biomaterials based on their origin, as natural and synthetic ones. Moreover, the advanced applications in pharmaceutical and medical domains are highlighted based on the specific mechanical and physical properties of biomaterials, concerning their use. The high-priority challenges in the field of biomaterials are also discussed, especially those regarding the transfer and implementation of valuable scientific results in medical practice.

“…Plasticizers are crucial additives that enhance polyvinyl chloride (PVC) polymer properties like flexibility, softness, and processability . With a 72% market share, phthalate plasticizers are the predominant commercially available plasticizers. , However, because of their low molecular weight, phthalates are highly susceptible to migrating out of the polymer matrix during use, which is potentially hazardous to human health. − Phthalates can interact with DNA, disrupt endocrine function, contribute to obesity and reproductive issues, and even cause cancer and malformations in extreme situations. − Therefore, the development of new environmentally friendly plasticizers is an effective strategy to counteract the negative effects of phthalates. Owing to its superior plasticizing capabilities and low biotoxicity, cyclohexanedicarboxylic acid (CHDA) ester is considered the best substitute for phthalate plasticizers and has been approved for a variety of markets, including medical devices, toys for children, food contact materials, and other products. , …”

Cyclohexane dicarboxylic acid (CHDA) ester, a kind of environmental-friendly plasticizer, can be produced by phthalates hydrogenation. However, the synthesis of catalysts with high activity and selectivity is a challenge due to the stability of aromatic rings. In this work, a series of ultrauniform Ru nanoclusters supported by γ-Al2O3 are synthesized for the hydrogenation of diisononyl phthalate (DINP). Results show that the conversion of DINP and the selectivity of diisononyl-cyclohexane-1,2-dicarboxylate (DINCH) both reach 100% at 140 °C and 3 MPa H2 pressure. Diisononyl-cyclohexene-1,2-dicarboxylate (4H-DINP) and 1,2-cyclohexanedicarboxylate-7-methyloctyl ester are found; the hydrogenation reaction network of DINP is constructed. Alkali metal ions adsorbed on the surface of Ru nanoclusters prepared by the polyol method can stabilize Ru3+-Hδ− species by electrostatic interaction, thus affecting the hydrogenation activity of the catalyst, following the order of Li+ > Na+ > K+ > Cs+. Ru-based catalysts prepared by the polyol method have good prospects for application in phthalates hydrogenation.
