The smallest skeletons in the marine world observed in 3-D by synchrotron techniques

Coccolithophores are microscopic marine algae that use carbon dioxide to grow, and release carbon dioxide when they create their miniature calcite shells. These tiny, abundant planktonic microorganisms could therefore be ...

3-D experiments shed new light on shape memory alloys

Shape memory alloys are well known for their remarkable properties—superelasticity, shape memory and actuation allow them to be crumpled up and then spring back to a "remembered" original shape.
