Long unobserved and recently discovered: towards a better understanding of protected‐area species dynamics using curated species lists

open access: yesEcography, EarlyView.
Protected areas are designed to shield populations from harmful human impacts. However, in the face of global climate change, a static approach to conservation within these areas is neither feasible nor desirable. One key measure of ecological change at this scale is the arrival of new species and the local extinction of others. Despite strong interest

Ultra‐Fast and Economical Pre‐Breakdown Electrochemical Synthesis of Intrinsically Conductive Polymer Suspension for Production of Safe Lithium‐Ion Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This paper presents a breakthrough pre‐breakdown electrochemical method for synthesizing polyNiMeOSalen suspensions, achieving an 83% yield and nanoscale dispersion ($1500/kg) and environmental impact (1.42 kg CO2eq/kg). We report a novel pre‐breakdown electrochemical synthesis method for producing polyNiMeOSalen suspensions with exceptional ...
