Article
Electrifying the upcycling of plastics
Polyvinyl chloride (PVC) is challenging to recycle owing to the formation of hydrochloric acid during depolymerization at high temperatures. Now, a method for upcycling PVC that relies on its intrinsic reactiv...

Continuous, autonomous subsurface cargo shuttling by nature-inspired meniscus-climbing systems
Water-walking insects can harness capillary forces by changing their body posture to climb or descend the meniscus between the surface of water and a solid object. Controlling surface tension in this manner is...

Diversity-oriented synthesis of polymer membranes with ion solvation cages
Microporous polymers feature shape-persistent free volume elements (FVEs), which are permeated by small molecules and ions when used as membranes for chemical separations, water purification, fuel cells and ba...

Universal chemomechanical design rules for solid-ion conductors to prevent dendrite formation in lithium metal batteries
Dendrite formation during electrodeposition while charging lithium metal batteries compromises their safety. Although high-shear-modulus (Gs) solid-ion conductors (SICs) have been prioritized to resolve the press...

Closed-loop recycling of plastics enabled by dynamic covalent diketoenamine bonds
Recycled plastics are low-value commodities due to residual impurities and the degradation of polymer properties with each cycle of re-use. Plastics that undergo reversible polymerization allow high-value mono...

Open AccessHarnessing liquid-in-liquid printing and micropatterned substrates to fabricate 3-dimensional all-liquid fluidic devices
Systems comprised of immiscible liquids held in non-equilibrium shapes by the interfacial assembly and jamming of nanoparticle−polymer surfactants have significant potential to advance catalysis, chemical sepa...

Open AccessMolecular understanding of polyelectrolyte binders that actively regulate ion transport in sulfur cathodes
Polymer binders in battery electrodes may be either active or passive. This distinction depends on whether the polymer influences charge or mass transport in the electrode. Although it is desirable to understa...
