Key to reducing defects in multi-materials

Materials used in the fields of aerospace, automobiles, medical equipment, and defense need to withstand extremely harsh environments. Small flaws in the materials, such as cracks, can lead to catastrophic consequences and massive economic loss. However, most materials cannot handle such high temperatures and pressures. Multi-materials, like functionally graded materials (FGMs), which combine different materials to produce improved performance, are ideal in this situation.

New imaging method makes microrobots visible in the body

Researchers at the Max Planck ETH Center for Learning Systems, Germany, have developed an imaging technique that for the first time recognizes cell-sized microrobots individually and at high resolution in a living organism.
