Synthesis and Application of P(EDOT-co-Py)@MWCNT Hybrid as Cathode Electrode for Aqueous Aluminum-Ion Batteries

Nanoenergy Advances
A hybrid material based on the copolymerization of EDOT (3,4-ethylenedioxythiophene) and Py (pyrrole), 1:1 monomer ratio, onto multi-walled carbon nanotubes (MWCNTs) was synthesized through a multistep functionalization approach.

Ten rules for robust taxonomy in ecological datasets

New Phytologist, EarlyView.
A workflow for better use and integration of taxonomic‐related information into ecological datasets. Summary Accurate taxonomy, including species identification and naming, underpins ecological inference, yet taxonomic information in ecological datasets is often inconsistently recorded or weakly standardized.
