Self‐Assembly of Organic–Inorganic Copolymers Toward Bio‐Inspired Cementitious Composites
Advanced Science, EarlyView.Organic–inorganic copolymerization of calcium silicate hydrate and thioctic acid produces a self‐organized nanocomposite inspired by the disordered collagen–mineral architecture of trabecular bone. The resulting material combines a compressive strength above 300 MPa with intrinsic physical reprocessibility, retaining over 80% of its strength and energy

Advanced Science, EarlyView.We demonstrate that the inverse relationship between viscosity and conductivity in structured electrolytes can be circumvented by leveraging their hydrogen bonding networks for Grotthuss proton transport. Using a mixture of imidazole and levulinic acid, we show that the existence of extended hydrogen‐bonded chains that can rapidly reorient result in ...
