Organotrifluoroborate‐Driven Phase Stabilization and Defect Suppression for Wide‐Bandgap Perovskites

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A multifunctional additive, trifluoro(pyrrolidin‐1‐ium‐1‐ylmethyl) borate (PyMe‐BF3), leverages B‐F coordination and N‐H hydrogen bonding to passivate undercoordinated Pb2+, fill halide vacancies, and suppress phase segregation. Its preferential enrichment at the buried interface targets the defect‐rich region, enabling simultaneous wide‐bandgap ...

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

open access: yesENERGY &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 ...

Ethnography in ESP

open access: yes
Understanding contextualized language use, how it mediates and is mediated by social practice has long been a central endeavor in English for Specific Purposes, with the aim of supporting the development of more tailored language instruction. This chapter examines how ethnographic approaches have become instrumental in this endeavor.
