Calcium oxychloride formation in pastes containing supplementary cementitious materials: Thoughts on the role of cement and supplementary cementitious materials reactivity

open access: yesRILEM Technical Letters, 2016
Over the last decade many concrete pavements in North America have begun to show excessive damage at the joints. This damage appears to be due to two primary causes: classic freeze-thaw damage due to local saturation caused by the pooling of water at the

Fast‐Responding O2 Gas Sensor Based on Luminescent Europium Metal‐Organic Frameworks (MOF‐76)

open access: yesAdvanced Functional Materials, EarlyView.
Luminescent MOF‐76 materials based on Eu(III) and mixed Eu(III)/Y(III) show rapid and reversible changes in emission intensity in response to O2 with very short response times. The effect is based on triplet quenching of the linker ligands that act as photosensitizers. Average emission lifetimes of a few milliseconds turn out to be mostly unaffected by

Differentiating the Synergistic Interactions Between Li+ Salts and Cyclic to Linear Carbonate Ratios to Enable Wide‐Temperature Performance of Lithium‐Ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
The coordination in carbonate solvents and degradation products of lithium difluoro(oxolato) borate (LiDFOB) salt enables sufficient passivation of both LiNi0.8Mn0.1Co0.1O2 (NMC811) cathode and graphite anode in the absence of ethylene carbonate (EC).

Protophilic TiOx/Ti3C2Tz Nanosheets for Hyper‐Efficient Closed‐Loop Pd Recycling

open access: yesAdvanced Functional Materials, EarlyView.
Protophilic TiOx/Ti3C2Tz NSs enable selective Pd(II) recovery through in situ adsorption‐reduction into Pd(0) NPs from spent catalyst leachates and industrial wastewaters. The resulting Pd/NS composites are directly upcycled as efficient HER electrocatalysts or regenerated for reuse through controlled surface regeneration.

Side Reaction Pathway Modulation for Hydrogen Evolution‐Free Aqueous Zn‐Ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
A ZnO–TeO2–Te ternary composite layer with a unique rice grain‐like morphology is spontaneously formed on the Zn anode via telluric acid additive. This functional interphase effectively suppresses side reactions such as zinc hydroxide sulfate formation, hydrogen evolution, and Zn corrosion, enabling highly reversible and stable Zn metal cycling in ...

Ion‐Selective Microporous Membranes via One‐Step Copolymerization Enable High‐Performance Redox Flow Batteries

open access: yesAdvanced Functional Materials, EarlyView.
A scalable one‐step copolymerization strategy is developed to produce low‐cost microporous ion exchange membranes that boost both the efficiency and lifespan of flow batteries. When combined with organic electrolytes in aqueous systems, these membranes enable safe and cheap flow battery energy storage, supporting the widespread integration of renewable
