Coins, monetisation and re-use in medieval England and Wales: new interpretations made possible by the Portable Antiquities Scheme. [PDF]

open access: yes, 2013
Coins are a vital source of evidence for many aspects of the medieval past. In this thesis a large volume of provenanced coin records collected and published online by the Portable Antiquities Scheme (PAS) are analysed to look for patterns of ...

Engineering Intelligent Graphene Oxide‐Cellulose Membranes: Suppressing Thermal Runaway for a Safer Aqueous Zinc‐Ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
A novel thermos‐responsive hydroxypropyl cellulose/graphene oxide (HPC/GO) composite membrane is fabricated for reversible temperature‐gated ion transport in aqueous zinc‐ion batteries. Enabled by LCST‐driven structural transition, unimpeded ion diffusion at room temperature delivers high capacity, while elevated temperature suppresses transport; full ...

Dynamic Proton Activity Regulation via Brønsted Bases Enables Durable and High‐Energy‐Density Zn||MnO2 Batteries

open access: yesAdvanced Functional Materials, EarlyView.
Our study demonstrates Brønsted base‐mediated proton transfer for HOAc dissociation regulation in weakly acidic electrolytes, where imidazole achieves optimal dynamic proton equilibrium‐simultaneously stabilizing Zn anodes and enabling efficient Mn2+/MnO2 conversion.

Formation of Quasi‐Decoupling Interface on Li‐Metal Anodes in High Donor Electrolyte

open access: yesAdvanced Functional Materials, EarlyView.
Li‐metal anode (LMA) is stabilized by introducing Li2Te2 as an electrolyte additive for Li‐metal batteries. Upon contact with Li, Li2Te2 spontaneously converts to Li2Te, which electronically isolates Li from dimethyl sulfoxide due to its large bandgap and minimal Bader charge transfer.
