Industry already accounts for approximately one-third of global greenhouse gas emissions and these emissions are growing quickly as the developing world industrializes and emissions-intensive materials are used to deliver better performing technologies. We need sustainable materials processing solutions that fit the scale and urgency of the challenge.

Nanoscale dual-phase alloys composed of alternate metal (soft) and intermetallic or covalently bonded (hard) strengthening phase exhibit high strength, high strain hardening rate, and measurable plasticity at ambient and elevated temperatures. Here we report unusual plasticity carriers in intermetallic Al 2 Cu and covalently bonded Silicon in Al-Si and Al-Cu alloys based on multiscale experiments and modeling.

We are working to accomplish for cells something akin to what a shepherd and sheepdogs bring to flocks of sheep: control over large-scale collective cellular motion. As coordinated cellular motion is foundational to many forms of multicellular life, being able to ‘herd’ or program large-scale cell migration raises exciting possibilities for accelerated healing, tissue engineering, and novel biomaterials.

The ability to move is a trait of all animals. Yet how do animals, including ourselves, get around in this complex and uncertain world with an ease and agility we find hard to recreate in engineered systems?
