Controlled Optically Active Hierarchical Nanostructures of Side‐Chain Sequence‐Regulated Graphene Nanoribbons

open access: yesAdvanced Science, EarlyView.
The restrained side‐chain accessibility and versatility of GNRs extremely impede their multifunctionality, solution processability, and numerous solution‐based applications. We report herein a robust liquid‐phase bottom‐up synthesis approach for high‐efficiency preparation of side‐chain sequence‐regulated functional GNRs.

Three Dimensional Printing of Bioinspired Composite Aerogels for Solar Steam Generation

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
Freshwater scarcity demands efficient purification strategies. Inspired by desert grasses, reduced graphene oxide‐doped polyacrylamide aerogels with longitudinal grooves are fabricated via high‐speed three‐dimensional printing and freeze‐drying. The biomimetic design enables dual‐mode water transport, achieving a capillary flow of 2.16 cm in 10 minutes
