| In their chiral nematic states, the materials have a helical macrostructure which acts like a diffraction grating and selectively reflect light just like a compact disc does. |
| Macrostructure is characterized by the width of annual rings defined by the number of rings per 1cm of the section measured in radial direction on a crosscut. |
| It's delimitation: the macrostructure must be delimited historically, geographically, thematically and depending on the knowledge of language from the supposed users. |
| The diffusion coefficients determined are then averaged over the macrostructure of the surrounding excited volume. |
| The macrostructure of the shell surface ensures a safe primary fixation and promotes the osseointegration of the cup. |
| The sample can then be etched to reveal the microstructure and macrostructure of the metal. |
