Residual capability of alkali binding by hydrated pozzolanic cements in long-service concrete structures [PDF]

open access: yes, 2018
An experimental procedure was developed and applied to cement pastes made with two different pozzolanic cements (CEM IV/B (P) and CEM IV/B (V)) in order to ascertain the existence of a residual capability of alkali binding by long-term hydrated ...

Redox Oligomer Assembling Hierarchical Reinforced Framework Cathodes for Ultra‐Stable High‐Performance Zinc‐Ion Batteries

open access: yesAdvanced Science, EarlyView.
Redox phenoxoline‐benzoquinone oligomer has been designed as reinforced concrete framework like freestanding cathodes for high‐performance ZIBs. An optimal specific capacity of 339.5 mAh g−1 was contributed with exceptional retention of 87.5% after 65 000 cycles at 10 A g−1. Flexible energy storage is also demostrated.
