Toward Energy Efficient Electrochemical Valorization of Waste Nitrate and Sulfide

open access: yesAdvanced Materials, EarlyView.
This work introduces an integrated electrochemical strategy couples nitrate reduction with sulfide oxidation for energy‐efficient wastewater valorization. A Cu‐Co dual‑site catalyst, engineered for close proximity, promotes *NO2 relay and subsequently NH3 formation, enabling the system to operate at substantially reduced cell voltages and produce high ...

Mistletoe‐ and Mussel‐Inspired Fabrication of Hierarchically Structured Protein‐Cellulose Scaffolds From Biomolecular Condensates

open access: yesAdvanced Materials, EarlyView.
Merging materials processing tricks inspired by mussel and mistletoe fiber fabrication, solutions of cationic mussel byssus proteins were mixed with modified anionic nanocrystalline cellulose, producing distinctive core‐shell condensates. Simple processing of condensate suspensions using freeze‐drying produced hierarchically structured porous protein ...

The Vegan Villain Sets Out to The End of Summer: Functionalized Coatings as Biohybrid UV‐Sensors

open access: yesAdvanced Materials Interfaces, EarlyView.
This study introduces biohybrid coatings incorporating E. coli biomass expressing photoconvertible fluorescent proteins as UV‐A responsive elements. Upon irradiation at 400 nm, the coatings exhibit an irreversible fluorescence shift from green to red within 15 min. Notably, the photoconversion capability is retained after >1 year of storage.
