Investigation of the mechanical stability of polyethylene glycol hydrogel reinforced with cellulose nanofibrils for wound healing: Molecular dynamics simulation

Amin Koochaki et al.

Summary: Wound healing can be improved through various materials, and nanocomposites are considered promising structures for this purpose. In this study, a PEG hydrogel-cellulose nanocomposite was introduced to enhance wound healing. Molecular dynamics simulations were used to analyze the mechanical stability of the nanocomposite, showing its physical stability at standard conditions. The results demonstrated that the inclusion of cellulose into the PEG hydrogel improved its mechanical performance, making it suitable for clinical applications.

The effects of atomic percentage and size of Zinc nanoparticles, and atomic porosity on thermal and mechanical properties of reinforced calcium phosphate cement by molecular dynamics simulation

Shakour Shojaei et al.

Summary: This study used MD simulation to investigate the effects of different percentages and sizes of NPs, as well as porosity, on the thermal and mechanical behavior of reinforced cement. Increasing the NPs percentage from 1% to 3% increased the maximum temperature, but further increasing it to 5% decreased the maximum temperature. Increasing the radius of Zn NPs improved the ultimate strength and Young's Modulus. Increasing porosity resulted in a decrease in ultimate strength, Young's Modulus, and maximum temperature.

Advances in biodegradable and injectable hydrogels for biomedical applications

Yi Li et al.

Summary: In situ-forming injectable hydrogels are smart biomaterials with great potential in various biomedical applications, including drug/protein/gene delivery, tissue engineering, and regenerative medicine. These hydrogels can be injected into living bodies at room temperature, gradually degrade over time, and release active substances.
