Nanofiber PVA‐Based Membranes Incorporating Functionalized Spanish Broom Derivatives for Sustainable Water Purification

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study investigates Spanish broom (Spartium junceum) as a renewable source for electrospun composite membranes in sustainable water purification. MCC and biochar were functionalized with eco‐friendly precursors and nanomaterials (i.e., HNT, β‐CDs) to develop hybrid PVA nanofiber composites.

Molten Salt Electrolyte for Enhanced Low‐Temperature Sodium Liquid Metal Batteries

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study introduces the application of a low‐temperature, high‐conductivity, solvent‐free Na/KFSI molten salt electrolyte in sodium liquid metal batteries. Additionally, this electrolyte facilitates the formation of a stable and NaF‐rich cathode electrolyte interphase (CEI) on the alloy cathode, enabling stable cycling at an unprecedentedly low ...

Carbon‐Negative Upcycling of Sewage Sludge into Superiorly Stable Gel Via Liquid‐Phase Utilization Strategy for Water‐Remediation

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This work developed a low‐temperature sludge hydrothermal coupled with gel crosslinking strategy which could upgrade the waste liquid generated from sewage sludge hydrothermal treatment into the hydrothermal‐liquid‐gel. The inventive hydrothermal‐liquid‐gel exhibited the enhanced pollutant removal capability, high synthetic stability, and superior ...
