A novel shear-thinning hybrid bioink with good printability, mechanical support, biocompatibility, and bioactivity was developed by combining gellan gum, sodium alginate, and thixotropic magnesium phosphate-based gel (GG–SA/TMP-BG).

Atom-thick two-dimensional materials usually possess unique properties compared to their bulk counterparts. Their properties are significantly affected by defects, which could be uncontrollably introduced by irradiation. The effects of electromagnetic irradiation and particle irradiation on 2H MoS 2 two-dimensional nanolayers are reviewed in this paper, covering heavy ions, protons, electrons, gamma rays, X-rays, ultraviolet light, terahertz, and infrared irradiation. Various defects in MoS 2 layers were created by the defect engineering. Here we focus on their influence on the structural, electronic, catalytic, and magnetic performance of the 2D materials. Additionally, irradiation-induced doping is discussed and involved.

A novel magnesium phosphate-based gel (TMP-BG) with excellent printability was developed for application in 3D printing.
