Transplantation of bone implants is currently recognized as one the most effective means treating defects. Biobased and biodegradable polyester composites combine good mechanical degradable properties polyester, thereby providing an alternative for implant materials. Bone tissue engineering (BTE) accelerates defect repair by simulating microenvironment. Composite scaffolds support formation further accelerate process repair. The introduction 3D printing technology enables preparation to be more precise, reproducible, flexible, which a very promising development. This review presents physical BTE summarizes strategies adopted domestic international scholars improve based on biobased polyester/ceramic in recent years. In addition, future development prospects field challenges expanding production clinical applications are presented.

Abstract Recycled polyethylene terephthalate (RPET) was doped with Neodymium Oxide (Nd 2 O 3 : 0, 1, 2, 4, and 8 wt.%) to investigate its structural, optical, dielectric, mechanical properties. X-ray diffraction (XRD) analysis revealed that pure RPET exhibited an amorphous structure, while the incorporation ofNd induced formation of crystalline phases, crystallinity increasing as Nd concentration increased. Fourier-transform infrared (FTIR) spectroscopy identified chemical interactions between , evidenced by a new band around 535 cm −1 . Optical using diffuse reflectance UV–Vis showed reduction in gap from 3.75 eV for 2.25 8wt.% samples, indicating enhanced optical Dielectric studies doping significantly decreased dielectric constant RPET, contributing thermal stability constant. Furthermore, loss conductivity improved, observed across varying temperatures. Dynamic (DMA) adding wt.% reduced storage modulus 1.62 GPa approximately 0.26 at 35 °C, attributed structural softening. These improvements suggest -doped is suitable applications requiring conductive REPT, low modulus, stability, energy dissipation capabilities.

Review Upcycling of Waste Plastics into Value-Added Chemicals Jin Xu and Jing Zhang * State Key Laboratory Chemical Engineering, East China University Science Technology, 130 Meilong Road, Shanghai 200237, Correspondence: [email protected] Received: 8 November 2024; Revised: 22 January 2025; Accepted: 24 March Published: 27 2025 Abstract: The rapid increase in plastic production has led to a severe waste crisis, driving the development various recycling technologies mitigate this growing issue. However, these often encounter substantial economic environmental challenges their implementation. An increasingly attractive alternative is chemical upcycling, which can transform plastics value-added chemicals. This review systematically examines upcycling applicable major commercial plastics, including polyethylene terephthalate (PET), polyolefins, polystyrene (PS), polyvinyl chloride (PVC). We focus on key strategies such as solvolysis, catalytic pyrolysis, hydrocracking hydrogenolysis, along with some emerging approaches electrocatalysis photooxidation, aiming summarize trends plastics.

Coassembly of hybrid microscale biomatter for robust, water-processable, and sustainable bioplastics

Science Advances, Год журнала: 2025, Номер 11(14)

Опубликована: Апрель 2, 2025

Unlike conventional methods that typically involve extracting biopolymers/monomers from biomass using lots of hazardous chemicals and high energy, the direct utilization biological matter (biomatter) without extraction offers a more sustainable alternative for bioplastic production. However, it often suffers insufficient mechanical performances or limited processabilities. Herein, we proposed hybrid microscale biomatter coassembly strategy leverages interactions between inherent microarchitectures waste cotton fiber pollen particles. With minimal preprocessing, they form castable slurry can spontaneously organize into dense fiber-laminate network, exhibiting properties (52.22 megapascals 2.24 gigapascals) toxic organic heavy machinery. The resulting features controlled hydration-induced microstructural disassembly/reassembly, enabling water-based processability complex, dynamic architectural systems. In addition, demonstrates good biodegradability, closed-loop recyclability, satisfactory environmental benefits, outperforming most common plastics. This study provides an instant nature-derived paradigm bioplastics’ production, processing, recycling, offering promising solution facilitating eco-friendly advanced applications.
