Growing evidence supports a critical role of metal-coordination complex crosslinking in soft biological material properties such as underwater adhesion and self-healing. Given their exploitation in such desirable material applications in nature, bio-inspired metal-coordinate complex crosslinking no doubt provides unique possibilities to further advance synthetic polymer materials engineering. Using bio-inspired metal-binding polymers, initial efforts to mimic these material properties have shown promise. In addition, novel opportunities for new fundamental insights on how hierarchical polymer network mechanics can be strongly coupled to supramolecular crosslink dynamics are also emerging. Early lessons from studies of these hierarchical chemo-mechanical couplings will be presented.
Computer Science rests on an unphysical division between the description of a computation and its implementation. Many issues in computing, including its scalability, efficiency, and security, arise at that interface. I will introduce alternative approaches to aligning the representations of hardware and software, and explore some of the social and economic implications of programming atoms as well as bits.
