Carbon nanotubes (CNTs) were aligned in gelatin methacryloyl (GelMA) hydrogels using dielectrophoresis approach. Mouse embryoid bodies (EBs) were cultured in the microwells fabricated on the aligned CNT-hydrogel scaffolds. The GelMA-dielectrophoretically aligned CNT hydrogels enhanced the cardiac differentiation of the EBs compared with the pure GelMA and GelMA-random CNT hydrogels. This result was...
In this study, various amounts of oxygen were added to Ti–10Cr (mass%) alloys. It is expected that a large changeable Young’s modulus, caused by a deformation-induced ω-phase transformation, can be achieved in Ti–10Cr–O alloys by the appropriate oxygen addition. This “changeable Young’s modulus” property can satisfy the otherwise conflicting requirements for use in spinal implant rods: high and low...
