Self‐Charging Persistent Mechanoluminescence with Mechanics Storage and Visualization Activities

open access: yesAdvanced Science, 2022
AbstractPersistent mechanoluminescence (ML) with long lifetime is highly required to break the limits of the transient emitting behavior under mechanics stimuli. However, the existing materials with persistent ML are completely trap‐controlled, and a pre‐irradiation is required, which severely hinders the practical applications.

Layered Potassium Titanium Niobate/Reduced Graphene Oxide Nanocomposite as a Potassium-Ion Battery Anode

open access: yesNano-Micro Letters, 2023
Highlights KTiNbO5 and KTiNbO5/reduced graphene oxide (rGO) nanocomposites were successfully synthesised via solvothermal methods. Optimising the rGO wt% yielded a composite with 12 wt% (KTNO/rGO-12).

Supercapattery: Merit merge of capacitive and Nernstian charge storage mechanisms [PDF]

open access: yesCurrent Opinion in Electrochemistry, 2020
Supercapattery is the generic name for hybrids of supercapacitor and rechargeable battery. Batteries store charge via Faradaic processes, involving reversible transfer of localised or zone-delocalised valence electrons. The former is governed by the Nernst equation.
