3D-printed poly(ethylene) glycol diacrylate (PEGDA)-chitosan-nanohydroxyapatite scaffolds: Structural characterization and cellular response.

Polymer-based scaffolds with bioactive materials offer great potential in bone tissue engineering. Polyethylene glycol diacrylate (PEGDA) scaffolds fabricated via liquid crystal display 3D printing technique lack inherent osteoconductivity. To improve such properties, chitosan of 10 and 20 wt% and nanohydroxyapatite (nHA) (3-10 wt%) were incorporated into PEGDA scaffolds.

Synergistic effects of the hybridization between boron-doped carbon quantum dots and n/n-type g-CN homojunction for boosted visible-light photocatalytic activity.

Dye wastewater has raised a prevalent environmental concern due to its ability to prevent the penetration of sunlight through water, thereby causing a disruption to the aquatic ecosystem. Carbon quantum dots (CQDs) are particularly sought after for their highly tailorable photoelectrochemical and optical properties. Simultaneously, graphitic carbon nitride (g-CN) has gained widespread attention due to its suitable band gap energy as well as excellent chemical and thermal stabilities.
