Designing for Degradation: Transient Devices Enabled by (Nano)Cellulose

open access: yesAdvanced Materials, EarlyView.
Recent progress in transient devices enabled by (nano)cellulosic materials is reviewed. Transiency mechanisms, advantages of nanocelluloses, and a suite of applications are discussed. A circular thinking approach coupled with life cycle assessment is applied to critically revisit the potential, advantages, and challenges of nanocellulose‐enabled ...

Rapid Surface Reconstruction of In2S3 Photoanode via Flame Treatment for Enhanced Photoelectrochemical Performance

open access: yesAdvanced Materials, EarlyView.
A rapid surface reconstruction strategy is proposed to enhance the charge collection efficiency and stability of indium sulfide (In2S3) photoanode via a high‐temperature flame treatment. This method selectively transforms the In2S3 surface into a diffusionless In2O3 and generates bulk sulfur vacancies, resulting in surface‐reconstructed In2S3 (sr‐In2S3)

A Bio‐Inspired Perspective on Materials Sustainability

open access: yesAdvanced Materials, EarlyView.
This perspective discusses natural materials as inspiration for sustainable engineering designs and the processing of materials. First, circularity, longevity, parsimony, and activity are presented as essential material paradigms. The perspective then uses many examples of natural and technical materials to introduce principles such as oligo ...
