DOI: 10.1002/adma.202203049

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.

Published in 2017 at "Macromolecular Materials and Engineering"

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/acsami.3c15690

Abstract: Metallic lithium (Li) is considered as the "Holy Grail" anode material for next-generation energy storage systems due to its extremely high theoretical capacity and low electrochemical potential. Before the commercialization of the Li electrode, dendritic… read more here.

Published in 2021 at "Journal of the American Chemical Society"

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.
