Slimming down through frustration Abstract In many diseases, proteins aggregate into fibers. Why? One could think of molecular reasons, but here we try something more general. We propose that when particles with complex shapes aggregate, geometrical frustration builds up and fibers generically appear. Such a rule could be very useful […]
From cylinder packings to auxetic periodic tensegrity structures Abstract I will present a chiral, triply-periodic tensegrity structure, which displays local reentrant geometry at its vertices. Our tensegrity structure is based on the β−Mn cylinder packing from structural chemistry, and contains all symmetries of the cylinder packing itself. The tensegrity structure is auxetic, as demonstrated by the modelling of a quasi-static extension and compression […]
