Abstract: Most gels and elastomers introduce sacrificial bonds in the covalent network to dissipate energy. However, long‐term cyclic loading caused irreversible fatigue damage and crack propagation cannot be prevented. Furthermore, because of the irreversible covalent crosslinked… read more here.

DOI: 10.1002/mame.201700347
Abstract: Polybenzimidazole membranes imbibed with phosphoric acid can support high proton conductivity at 120–200 °C, and have therefore emerged as the state-of-the-art electrolytes for fuel cells operating in this temperature range. This work presents a novel… read more here.

DOI: 10.1021/jacs.1c01642
Abstract: This study explores a bottom-up approach toward negatively curved carbon allotropes from octabenzo[8]circulene, a negatively curved nanographene. Stepwise chemical reduction reactions of octabenzo[8]circulene with alkali metals lead to a unique highly reduced hydrocarbon pentaanion, which… read more here.
