Fabrication and evaluation of PLA/MgAlO scaffolds manufactured through 3D printing method.

In this study, we synthesized magnesium aluminate spinel (MgAlO) with a particle size ranging from 35 to 70 nm using a facile combustion approach. Then, we used a 3D printing (FDM) machine to produce PLA/x wt% MgAlO (x = 0, 2, 4, 6, and 8) scaffolds. To investigate the crystal structure, microstructure, biodegradability, and thermal characteristics of the produced materials, we employed X-ray diffraction analysis (XRD), field emission scanning electron microscope (FESEM), Inductively Coupled Plasma (ICP), Simultaneous Thermal Analysis (STA), and compressive strength analyses.

Structural and optical characterizations of Ce -doped YSO phosphors via the addition of TEOS.

In this work, Y O phosphors were synthesized utilizing facile sol-gel, combustion, and solid-state techniques. The tested synthesis processes provided various particle sizes from nano to submicron. To synthesize YSO:Ce via a sol-gel method, tetraethylorthosilicate (TEOS) was used as the precursor for SiO .
