An investigation of joint tissue derived stem cells for articular cartilage tissue engineering
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2011)Tissue engineering has emerged as a promising approach to repair damaged articular cartilage. The associated drawbacks with the isolation and expansion of chondrocytes from autologous tissue have prompted significant ... -
Towards engineering whole bones through endochondral ossification
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2014)A number of clinical situations exist where bone regeneration is required in large quantities, such as for the treatment of critical size bone defects and for the replacement of whole bones lost due to trauma or disease. ... -
On the use of indentation technique to assess fracture properties of ceramics at the microscale
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2011)Classic methods to determine fracture properties of ceramics (like Single-Edge Notched Beam or Compact Tension) are accurate at the macroscale but inappropriate to estimate local fracture properties which are decisive at ... -
Acceleration of engineering and scientific applications using trivial operand processing
(Trinity College (Dublin, Ireland).
