Hollow Titanium Nitride Nanotruss (image) California Institute of Technology Share Print E-Mail Caption This image shows a three-dimensional, hollow titanium nitride nano truss with tessellated octahedral geometry. Each unit cell is on the order of 10 microns, each strut length within the unit cell is about three to five microns, the diameter of each strut is less than one micron, and the thickness of titanium nitride is roughly 75 nanometers.
