Acceleration of spheroidisation in a medium carbon steel processed by equal channel angular pressing Open
A medium carbon alloy steel was processed using equal channel angular pressing (ECAP) with a view to accelerating the softening process during subsequent annealing. The steel was pressed at 600°C for up to four passes. The original well-al…

Three-dimensional bioprinting of artificial ovaries by an extrusion-based method using gelatin-methacryloyl bioink Open
The aim of this study was to design and fabricate a three-dimensional (3D) printed artificial ovary. We first compared the printability of gelatin-methacryloyl (GelMA), alginate and GelMA–alginate bioinks, of which GelMA was selected for f…
